Design Problem
• State the design problem clearly. Explain how
you intend to solve it in general terms.
• The Problem and Design Brief are sometimes
viewed as two different sections of the design
process. However, they are very closely related.
Before you can can start a design project you
must find a ‘problem’ to solve. Sometimes this
may be given to you as a question set by the
teacher or the Examinations Board and is
usually a paragraph of writing. The ‘design brief’
follows the ‘problem’ and states clearly how you
intend to solve the design problem.
4
Analisys
• List as many questions as you can about the
project you are attempting. E.g. What
materials can I use ?
What safety considerations must I keep in
mind ?
• The ANALYSIS is one of the early sections in
the design process. It involves listing as
many questions as you can think of
regarding your project. The questions will
vary from project to project but usually the
majority of these questions are the same,
whatever the project you are attempting.
5
Synthesis
• Answer the questions in the analysis
• The ‘Synthesis’ is the section that follows the
‘Analysis’ and is the answers to the questions.
Usually it is impossible to answer all the
questions until you have nearly completed the
the design project. You will find that some
questions can only be answered when the
research section has been completed. For
example, any question on the choice of
materials, or the way ergonomics is applied to
your project, must be answered after you have
researched these important areas.
6
Solution
• Produce a working drawing of your solution with a
parts list. This must have measurements and
constructional details.
• A working drawing is the final ‘constructed’ drawing,
produced as part of the design process. It usually
consists of a front, side and plan view of the
solution. Sometimes there are two views but this
depends on the complexity of the solution.
Dimensions are added so that any person using the
working drawing can manufacture the design.
Usually there are at least six dimensions but you can
add as many as you feel are required in order for the
manufacturer to make your solution.
7
Evaluation
• Designers evaluate their finished products or
prototypes in order to test whether they work
well and if the design can be corrected or
improved. Whatever you have designed it is
important to evaluate your work constantly
during the project.
Evaluation can take a variety of forms:
– General discussion with other pupils, staff and
others.
Questionnaires / surveys carried out at any time
during the project.
Your personal views, what you think of existing
designs.
Most important of all - what do you think of your
designs, prototypes and finished products ?
Can you think of any other ways of evaluating
your work ?
