The document discusses the product design process. It begins with identifying user needs through research. Designers then generate potential solutions by prototyping ideas without constraints. Prototypes are tested with users to get feedback. The design process is iterative, with visualization of ideas, analysis and refinement, leading to implementation. Drawings at different stages communicate and document the solution without ambiguity. An example chair design is provided that is ergonomic and encourages good posture while having a fun personality.

1. Introduction
1. Try to write a description of this object.
2. Test your written description by having
someone attempt to make a sketch from
your description.
You can easily understand that¡
The word languages are inadequate for
describing the size, shape and features
completely as well as concisely.
Cylinder
Drawing: (A Graphical Representation)
The Fact about
If compared with Verbal or Written Description,
Drawing offers idea about the Shape, Size & Appearance of any
object or situation or location, that too in quite a less time.
2. Composition of Graphic Language
Graphic language in ¡°engineering application¡± use
lines to represent the surfaces, edges and contours
of objects.
The language is known as ¡°drawing¡± or ¡°drafting¡±.
A drawing can be done using freehand, instruments
or computer methods
Freehand Drawing
The lines are sketched without using
instruments other than pencils and erasers.
are used to draw straight lines, circles, and curves concisely
and accurately. Thus, the drawings are usually made to scale.
Instruments Drawing
Computer methods
The drawings are usually
made by commercial
software such as
AutoCAD, solid works
etc.
3. Elements of Engineering Drawing
Engineering drawing are made up of
graphics language and word language.

4. What Is Product Design?
? Product design is the process of identifying a market opportunity, clearly defining the
problem, developing a proper solution for that problem and validating the solution
with real users.
¡°Design thinking is a human-centered approach to innovation that draws from the
designer¡¯s toolkit to integrate the needs of people, the possibilities of technology and the
requirements for business success¡±
¡°Good designers have always applied design thinking to product design (whether physical or
digital) because it¡¯s focused on end-to-end product development, and not just the ¡°design
phase¡± part¡±
5. What is the Product Design process?
Conduct research to develop a
deeper understanding of your
users/products.
Create a point of view that
is based on user needs and
insights.
Generate a range of potential
solutions by giving yourself and
your team total freedom.
Build a prototype (or
series of prototypes) to
test your hypothesis.
Return to your
users for
feedback.

14. Favorite chair, the ¡°Revolt chair¡± designed by Dutch designer, is a perfect example of an ergonomic chair. The seat is slightly
angled upwards to counter the forward sliding tension of the legs and the back plate is positioned perfectly to provide
lower-back support, but still allow freedom of movement for the shoulder blades. In addition to being comfortable and
great for your posture, this chair has a childlike personality and wants to be your best friend.
