Lec 01 Introduction to Product Design and Development

friends we are going to start our discussion
on the topic product design and development as you are well aware that this course is
a four weak course in which we will be discussing the various aspects of product design and
development i am happy to see they are lot of applicants lot of learners who have registered
for this course and i can i sure you that if you take interest in the course you will
not at all be disappoint it friends to start with ours ours is a manufacturing based economies
usually we call us call our self has a agriculture based economy but with the government programs
like make in india stand up india start up india there are so many issues in which we
can contribute and now our focus is more on manufacturing although our focus is there
on agriculture also but with passage of time we have to evolve our self and our focus should
also keep on changing for the betterment of the country as well as the society as a whole now in this course on product design and development
we should start our discussion with the very basic fundamental aspect that why new and
new products are required in the society or in in engineering applications as you will
see india is very good we want to make it as a manufacturing hub of the word but our
major focus in manufacturing is we are manufacturing the products we are assembling the products
but where we are lacking we are lacking in designing the products so were design approach
has to change our engineers have to become self sufficient self reliant in designing
the best possible products that are designed by the designers world wide
so if we see in manufacturing sector we have so many multinational companies were manufacturing
their products in our country but we are not the best designers the design of the car or
of the auto mobile is done in some other your of sure and india is used as manufacturing
hub to produce that product or to manufacture the that product or to assemble that product
so our focus should be to become a designers our focus should be to train our engineers
to become the best designers in the world all though many of our technical institute
like iits mits and other engineering institute have the focus and teach this course of product
design and development at the ug level but the tools and techniques slightly are not
covered in much detail so in this course we will try to and gage the learners in the practical
aspects of product design and development where have whereas we have the theoretical
as knowledge theoretical aspects are known to most of the engineers but the practical
aspects are missing so our focus would be to find tune the practical aspects of the
product design as well as how to develop a product so we will try to see if we can incorporate
some videos also in the lectures that your able to understand that how a complete development
of a prototype can also be done using the product design design and development approach
so today i will just like to introduce as a introductory lecture that what we are going
to do in this course what we are going to learn in this course and what why there is
a need for developing a new product and how we can develop a successful product or what
are the factors that we should keep in mind for developing a successful product
so let us start the presentation ah and try to understand the what we are going to do
in this particular course now this is the outline of the presentation first we will
discuss the course details what we are going to cover in this course secondly the new product
design basic concepts the need of the product design that the need of a new product design
product development new product development strategy with new product development process
and successful product development and product life cycle i will just like to introduce the
product life cycle and we will cover it in the next lecture the details and the analysis
that we can do based on the product life cycle now to start with let us first see the course
details now in course details week one our focus right now we are here we are at the
introduction stage of our course next we will cover the product life cycle we will cover
the product policy of an organization then selection of a profitable product what are
the factors what are the methods which can help us or what is the information or knowledge
that we require to select a profitable product that we will see again we will see the product
design process today i will just outline that what are the various stages but we will have
a detailed discussion that what should be kept in mind when we are going to design a
products so that will be a separate tutorial or a lecture on this product design process
and finally we will see the product analysis so many ideas come to us each one of us is
field up with ideas but in order to convert or in order to change those ideas into reality
and so that they can come or become a tangible product what are the analysis procedures that
are required that we will cover in our last section of week one that will be product analysis
then coming on to week two we will start our discussion with value engineering concepts
now value engineering is an important aspect which should be kept in mind while designing
a product why because the cost is the most important parameter that governs the product
design that we will see in the subsequent lecture so value engineering in is in itself
a complete subject which is generally not taught to the under graduate students in our
country that iit roorkee we have this course as one of the electives for our bachelor students
so i want to introduce this concept of value engineering to all engineers who are attending
this course or to all graduate who are attending this course i am not focusing by applications
or the examples of the case studies only for the engineers even the other learners who
are graduates and who have some kind of innovative mind set they can also attend this courses
or attend this lecture and can get benefited by the discussions that will have during the
course or the knowledge discussion or knowledge sharing that we will have during the course
even you can write to me with your suggestions we can do little bit of modification all also
if the delivery content of the course so that it is beneficial to all the learners who have
registered for the course so value engineering is a very you can say
important aspect in any design process and we will see that what do we know about value
engineering how much knowledge has been develop about value engineering what are the various
case studies related to value engineering and how the concepts and practice of value
engineering can help us to optimize our product design and make our product more competitive
in the market so in value engineering aspects we will be
covering the advantage is applications and ah applications specially in product development
then we will see value engineering problem identification and selection analysis of the
functions or anatomy of the function we will study so there are different types of functions
like ah primary function secondary function tertiary function necessary function unnecessary
functions so we will do that and we will learn that through functional analysis system technique
which is a standard technique of value engineering which is known as fast f a s t if you google
this word f a s t you will see so many examples of fast you will get so that we will cover
and then we will see few successful case studies where the principles of value engineering
have been applied and successfully implemented across the organizations not only in india
but across the world so this value engineering week will be very
very important and i feed that learners will be able to develop a completely new approach
towards product design after going through these lectures or these sessions on value
engineering after the week two in week three our focus will be to develop the skills related
to product design process in this our focus will be introduction of the various product
design tools then we will focus on quality function deployment usually known as qfd computer
aided design design for excellence robust design design for manufacturing design for
assembly and ergonomics in product design so you can see each one of these is a subject
in itself and we will try to bring together only the most important parts of these concepts
like the design for manufacturing the design for assembly there are standard guidelines
for keeping in mind or standard guild lines for the engineers which help the engineers
to develop the products and in order to make it manufacturable manufacturable we should
say easily manufacturable easy to assemble all right so we will cover all this concepts
like design for manufacturing design for assembly not the concept point of view but the application
point of view we will try to explain we will try to understand these with the help of examples
that this was the situation this was the product this was manufactured using this process but
after the applying design for manufacturing guidelines how the product design was changed
to suite to the need of the manufacturing engineer and how it became easy to manufacture
that product after redesigning it you following the dfm or the df guidelines so we will take
those examples in due course of time and you will develop that thought process that if
you use this guidelines how you can modify the existing products and make their manufacturing
simple or in design of a new product you will keep this guidelines in your mind beforehand
and your manufacturing will become easier so all those condition we will see with the
help of various case studies finally we will see the ergonomics in product
design and which is a important accept for example all of you may be sitting on a chair
or may be lying on your bed and watching the tv or watching this lecture on the screen
so there has to be a concept of ergonomics in these your next should be positioned in
a way that it does not hurt you if your leaning in that position for half an hour
similarly if you are sitting on a table the eye ball contact with the screen should be
such that your eyes on get tiered so all these are basic principles of ergonomics which we
will be taken care and we are designing the product so we will see the principles of ergonomics
and our focus will not only the understanding what do we mean by ergonomics but we will
be trying to understand that how ergonomics can be used for designing the various products
and we will try to see the case studies where ergonomics has helped in the product design
so that the products have become successful in our last week we will focus on the design
for manufacturing and assembly guidelines we will see product design for manual assembly
suppose there is a product for example this camera which is recording this complete lecture
it has so many different parts i can see may be there may be two hundred parts that have
gone into this assembly very small assembly of the camera
now what design guideline should be done so that this assembly becomes easier it becomes
full proof and there is no problem while assembling this cam camera small set of but with so many
different different parts which have been joined together to make this complete structure
so all those guidelines we will see that in product design what are the guidelines for
the products which have to be assembled by manual operations then we will see what are
the guidelines for the products which have to be assembled by ah automatic operation
so the point is if you if you see the development of the course initially we are talking of
the product designed the concepts of value engineering in product design and surely we
are moving towards development of the product or the manufacturing of the product so if
you see the title of the course product design and development so the last two weeks more
or less will focus on developing of a prototype or developing of a model of the design that
we have to conceptualize during the first two weeks
so here you can see sorry here you can see the design guidelines for manufacturing of
metallic and nonmetallic products we will see suppose there is a product which has to
be made by casting operation we have to see that when we design that product we should
keep in mind that what are the problem area associated with casting the product so we
will keep those things in mind while designing the product so the during the manufacturing
stage we do not encounter any problem so all those things will be taken care what are the
standard guidelines or rules of thumb or we should be taken into account while we are
designing the product which has to be later on manufactured by any standard manufacturing
process it can be casting it can be forging it can be a sheet metal operation it can be
a machining operation so we will see what are the standard guidelines to be taken care
so the all that will be considered in this ah these ah particular sessions on design
guidelines for manufacturing of metallic and nonmetallic products and then we will see
a very important concept of rapid prototyping and we will see that why rapid prototyping
is important in todays scenario then we will see what is the concept and the advantageous
of rapid prototyping and as i have already told you our focus which will primarily be
on developing the skills related to the product design process
so we will see what are the standard manufacturing process is a standard techniques which are
used under rapid prototyping in which we will see the working principles of stereo lithographic
operators laminated object manufacturing and selective laser sintering and we will see
that how these princi how these processors or techniques work and what type of products
or prototypes we can make out of using these processors out of a concept of rapid prototyping
you can see the four weeks are filled with lot of lot of you can say titles lot of sub
topics but if we go systematically we should be able to address all these points and we
should be able may be after attending the course the deliver the deliverable should
be that you become of designer who has basic concept all basic knowledge about the about
the product development process the techniques use for prototyping the products and the techniques
use for manufacturing the product so it it covers the whole you can say gambit
of the product design prototyping and manufacturing so the knowledge base required is all these
three but even if somebody does not have a engineering background can do this course
as we are not going to delft too much into the details of manufacturing hours will be
a standard approach of product design and prototyping we will not be discussing too
much of manufacturing but the guidelines that have to be taken care of their definitely
we will see that what are the standard guidelines to be taken care when the product design is
getting converted into a tangible product for example the design of this pointer getting
converted into this pointer what are the process is that will be used we will try to understand
these with the help of certain examples and what factors should be consider or what standard
guideline should be consider then we are converting this prototype or in this particular design
into a final product so i think ah the next sessions will be much
more useful because today is a introductory session the next sessions will be much more
useful in cont in context of the application of the principles of product design and development
so let us now first see the introductory part of the course that why product design is an
important concept and why all engineers and all managers and all graduates should know
this concept because idea can come to anybody it is idea nobody as a proprietary right on
the idea ideas are universal anybody can develop a new idea i may have a idea anybody who thinks
fresh who has a innovative bent of mind can and who things the problems or thinks about
the problems all around is life ah can generate different types of ideas
so let us see now the basic process and why there is a need to design ah new product now
every organization has to design develop and introduce new products as a survival and growth
strategy now you can see if i ask you that the room in which you are sitting or the class
room where we are sitting if you see around you may be note down the five products and
just try to evolve that how these products have change or how the technology related
to these products has change or how the designs related to these products have change you
will see that you will be able to write at least ten pages on this five products that
initially these products use to be like this and now the products as evolved over a period
of time and has been converted into a new product
so you that is the importance as a survival or the growth strategy companies always keep
on doing research and development always generating new and new ideas always doing different types
of innovation like ah incremental innovation or the break through innovation to come up
with new and new products so that either they are able to maintain their market share or
they are able to grow or first is survival another is growth so first is to ensure the
survival in the market and second is to further increase their market share by launching new
and new and improvised products a related to the field of specialization
so that is one thing why the new products are being developed and the second thing is
the product design is conceptualization of an idea about a product and transforming of
the idea into the reality this i have already explain that in our course we will try to
see from idea generation to it culmi the culmination of that idea into the final product and to
transform the idea into reality a speci ah specification about the product is prepared
this we will try to understand when we will see in detail that how the product development
process takes place now new product design again thus this specification
is prepared by considering different constraints such as production process customer expectation
etcetera so we will see that when we will design the product we will see the constraints
such as the production process the as i have already explained that in week four our focus
will be to see that what are the various specifications which are dedicated to specific manufacturing
process for example casting that when the product is cast what are the guidelines to
be kept in mind if the if the product has to be made by forging process then what are
the guidelines to be kept in mind all that we will see i will outline all the guidelines
that if the product is made by casting process what are the factors or guidelines to be taken
care of similarly in the product design stage various
aspects of the products are analyzed also final decision regarding the product is taken
on the basis of analysis in week two we will see value engineering which is one of the
analysis tools and specifically focus on the cost of the product in week one our focus
will be on the analysis procedure we will see the marketing aspects the product characteristics
like durability and dependability the economic accepts and we will see the various reliability
aspects so those all aspects broadly we call them the analysis of the product you have
a idea then you have to analyze it using the standard technique and the standard analysis
procedures are followed i have just give an example of few standard procedures that are
followed to analyze the product so that analysis is also a important important part of the
product design then this decision can be any i aspect related to the product for example
dimension and tolerance is type of material for each component
so when we do the analysis we will under grow all this things we will see that what should
be the dimension of the product what should be the tolerances specified for that product
that product should be made of a which type of material and further bother each component
should be made up of the same material or it should be made up of different material
now if you try to relate this concept of product development with your life you can see you
may be right now using a desktop or a laptop for using for listening to this particular
discussion now you can see the materials the one can
have a metallic or body to the lap top one can have a plastic body to a desktop so why
there two different materials the type of selection of material is also very very important
some of you may be using a pen to write down some points now sometimes may be having a
metallic body sometimes may be having a plastic body some may be even using a pencil to do
the same task now it means that selection of a material for a particular product is
also equally important so all that also we will see when we will do the product analysis
now again i am coming to the same point because that is the most important point if you are
doing a course on product design and development first answer you should have in your mind
is that why new products are required when we are leaving a very when we are leaving
very comfortable life we are having the close to we are we are having food to eat we are
having a house to leave then why there is need for new and new products so we should
try to understand that why new products are required as i have already told you that there
is a need for the companies to either survive or to grow so therefore new products is a
necessity for the organization to keep their business going
so this points further high light the need of a new product design i will just reed it
for you organizations are required to design the new products for the following reasons
to be in the business for a long time which we can say is a survival for the company if
they do not come with the new products they will parish there is the very famous saying
if you do note absolute your product you will be absolute it from the market what does that
mean that mean that you have to automatically or you should make your product absolute and
come up with a new product otherwise you will be absoluted you will lose your business and
i will i dont want to name here but there are number of companies in india which were
not able to come up with innovative new designs of their products and ultimately your eliminated
from the market so you can yourself think this can be assignment problem that you can
find out five companies in five indian companies which did not innovate and finally lost business
so that can be one particular question in one of the assignments you can see first is
the survival strategy for the company to satisfy unfulfilled needs of the customers so there
can be so many example i will discuss in the next lectures where there there was a need
that existed in the market and there were companies which satisfied those needs and
made huge profits out of it so the second reason for new product design
process or product design developing a new product is to satisfy unfulfilled needs of
the customers third is too much computation in the existing product line so too you should
write t plus t double o too so too much computation in the existing product line so that is another
thing because of the computation when we will see the product life cycle when we will draw
that product life cycle you will see that there is a maturity phase in which there is
a competition by the various companies so all those that competition also leads to if
you see the automotive market very you good examples are there a companies making initially
two variants only but because of the competition setting in they divided their product variety
or product line into four five different ah automobiles
so the examples are well known to all of you so competition also leads to the new product
development the profit margin is on the decline so that is also one good reason for coming
up with the new product and these profit margin and the too much competition these two points
are related to the product life cycle so when we will come to product life cycle i will
explain these two points again there that why the competition leads to new product development
and why the profit margin leads to new product development or the decline in the profit margin
leads to new product development and the last point here is the companys existing product
line becomes saturated and the sale is on the decline so that is also one good reason
for coming up with ah new product now how much important should be give to the
design is where is easily or very ah importantly explained in this particular slide you can
see how the product design and manufacturing influence the price quality and cycle time
so seventy to eighty percent influence is exercised by design and only to twenty to
thirty percent of the ah you can see influence is shown by or has been reported by manufacturing
what does this mean this means that most of the things get logged at the design stage
only not designing the output will be in the form of a drawing which will have a bill of
materials so you will get that this particular product will be made by this material by this
process this many ah may be nuts and bolts and screws will be used for this product so
most of the things get freezed or most of the things get fixed at the product design
stage only so once the things get freezed the things
get fixed your price also gets fixed quality of the products also get fixed and the cycle
time also more or less get fixed so the influence major is of the design and then the manufacturing
also has some influence twenty to thirty percent if you remember in todays class only in the
very beginning i said that our engineer should focus more on the design philosophy or the
design thinking rather than manufacturing now as a country as a whole we are seeing
that we are manufacturing all the automobiles wherever design input into those automobiles
is very less so that we need to improve and therefore we are running such type of course
where we can slightly improve or slightly influence the design thinking of our engineers
or our budding engineers so this is you can see a very important diagram
we shows the design is an important aspect for any product manufacturing yes twenty to
thirty percent only design may be seventy to eighty percent influence not only on the
price but the quality and the cycle time so this thing has to be taken care of this you
can see a just a most simplistic example of the design of a bicycle you can see from eighteen
hundred and eighteen to nineteen hundred and seventy how the design of the cycle as evolved
over the period of time and current may be this is showing this figure taken from this
source is showing the design of the product till nineteen seventys only if you see the
cycles coming into two thousand sixteen two thousand seventeen the design may have further
change from this design of the mid nineteen seventys so you can see change in the design
nineteen sixty nine the rear wheel is bigger the front wheel is smaller eighteen seventy
the front wheel is bigger the rear wheel is smaller and then equal size wheels
so how the design can evolve may be why there was so many design changes and still there
are design change is change is continuing in the design of the bicycle why we need to
improve on the comfort of the rider we need to improve on the efficiency of the rider
we want need improve on the effectiveness with which our force is getting converted
it our power is getting converted into motion so we need to optimize all these things we
need to optimize based on the ergonomic principles so therefore the design as evolved over so
many periods so many years and current ah current design may not be the final design
may be another twenty years we may evens improvised design of a bicycle so its not that if we
are using the particular product there is no scope of design change the design change
can always happened and change is always should be or change should always be for the betterment
usually we say change is the only truth so change is inevitable and we have to always
keep on looking for change is or looking for the opportunities where we can further improved
the durability the dependability the efficiency the effectiveness of the products and for
that reason only we are under growing this small module of ten hours which can further
influence our design thinking and we can come up with ideas which can satisfy some needs
of the society now all of us have so many ideas but the reasons
for new product failure usually the mortality rate of the ideas is maybe i should say that
if you generate hundred ideas only two ideas will finally we come successful product so
there can be so many ideas floating around us but only two percent of the ideas will
reach to the market and the ninety percent of the ideas will died down so what can be
the reasons that if you have a idea but it is not becoming a successful product so with
the knowledge available in the various books on product design this is a summary of the
reasons which lead to the poor design first one is the over estimation of the market size
usually being for most optimistic in nature usually we say that the product that we are
designing is going to have a bang effect on the market and is going to become the most
successful product so we overestimate the market size and it leads to the product failure
second is the poor design of the product so we are going we may not discuss this first
aspect much in detail because it is relating to the marketing aspects but we will be focusing
on the design aspects so we will see that what is the poor design and what is the good
design than the incorrect positioning of the product wrong timing of launch it is prized
too high if the product is not competitive cost wise then maybe we may not be able to
capture too much of market and the product may not be successful so the prize is also
important in effective promotion again related to sales and promotion management influence
high development cost and computation so the development cost is important so we will further
see that how we can economize how we can optimize the development cost of the product
so management influence is also equally important because sometimes if you are the complete
support of the management the product may be ah is advertised properly is marketed properly
is given preference by the company which is a multi product company and therefore the
product gains in the market and it leads to the success of the product but if the management
is little bit appearance about the product and there is not complete or management support
for the product then sometimes it may lead to valuable that percentage of such cases
maybe very very minimal the major factors in this particular case are the point number
two that is product design and the second can be the high high development cost and
third is the computation and may be to some extend the wrong timing of launching the product
so majorly this four points we will try to address in our subsequent lectures and try
to see that how we can take care of these four points and make a come up with a design
which leads to success in the ah market so that we will try to see
now this is just a basic concept we will have one complete session on the product development
process but this is just an outline that how do a develop new product a new product we
have first the idea generation has i have already told you brain storming can be one
method of idea generation or reading different article related to the new products can be
one good method of idea generation then sometimes looking at the needs around you can be a very
good method of idea generation so idea generation is the first thing second is a screening of
ideas may be we will come up with the better ideas and take them to the next level then
the concept development and testing we will develop a complete concept about that product
it can be a rough sketch of that product just with the pencil we will draw down what is
there in our mind regarding that product rough sketch of the product will need to the concept
then the marketing strategy development suppose ah we have that concept and we have developed
it we will try to figure out the needs and requirements of people or the customers who
were going to used that product business analysis a complete business plan bp usually we call
that can be develop that how much product should be sold in the market to reach to the
brake even else is how much money should be invested to develop this idea into a tangible
product all those things will be sorry all those things will be discuss that the business
analysis level then the product development test marketing and commercialization i should
i tell you that this is not the standard approach which is true in case of each and every product
different segments of the products are there and different segments of product different
such approaches will be there but we will try to develop a thought that for any idea
what are the standard methods for developing or bringing that idea into reality or bringing
that idea into a tangible product so this may not be the standard approach in different
books you may find different approach is of product development and we will try to take
out the best out of each approach or the ah you can say summary of all these approaches
and try to develop our thoughts related to the product development process
now for any successful product development they are five characteristics which we should
keep in mind first one is a product quality product cost development time development
cost and the development capability so these are the five keywords for making successful
products so our focus should be on quality cost time manufacturing cost and the capability
of the company so if we can make best to possible utilization of the development capacity of
a company we can a definitely come up with the products or should i say successful products
and that is the only target that we should come up with successful products
now slightly i would like to introduce today a concept of product life cycle because this
is important for the product development process or the new product development process and
then may be in the next session we will have a complete discussion related to the product
life cycle the product life cycle is the course that a product sales and takes profits takes
over its lifetime so again i will read it for you slightly i was a bit not correcting
reading it product life cycle is the course that a products sales and profits take over
its lifetime in the next slide i will show you how a typical product life cycle looks
like and second point is the product life cycle concept is derived from a fact that
a given products volume and revenue follow a typical pattern of four phases
now what are these four phases that we are going to see so how the sales of a product
will change when it is lost into the market over a period of time that is usually called
the product life cycle and there are typical behavior which is observed for general type
of products and that behavior we try to analyze and use it for our decision making related
to the product development strategy and product development process
so next slide we can see the four phases of life cycle of a product are first one is a
on y axis we see annual sales volume and x axis is the time this is the time and the
annual sales volume the four phases of life cycles of product are first one is introduction
growth maturity or stabilization and decline again to revise introduction growth maturity
and decline so any product which is launched in the market will definitely under growth
these four stages or the sales of that product or the demand of that product will go through
these four stages for starting from introduction growth maturity and finally decline and these
type of inform these type of information or these type of cycles usually will help us
in our decision making related to the new product development
so i will finish todays session here with the brief very brief introduction of product
life cycle but in the next session we will definitely see product life cycle in detail
and we will try to understand that what type of decisions we can make based on the product
life cycle so to revise what we have covered into todays class i have given you ah brief
outline of the topics that we are going to cover in this course on product design and
development then we i have seen we ah i have try to address why new products have to be
develop we have taken an example of a cycle that how it has evolved over a period of time
and finally we have seen that what are the major reasons that lead to the failure of
the product and in the last slide we have just seen a brief we can say in order to continuity
among the lecture we have just seen that there is a product life cycle and the annual sales
of the product change is over a period of time and how the change is how the product
annual sales change over a period of time in in case of general products or in case
of tangible products has been given so there are four stages first one is the introduction
second one is the growth third one is the maturity and forth one is the decline so next
lecture we will see that what decisions we can take of if we have a product life cycle
of a product available or a similar product available with us so thank you very much we
will may be now interact again in lecture number two which will be related to the product
life cycle thank you
