What is a design ?
• The word “design” is often used as a genetic term that refers to
anything that was made by a conscious human effort.
• Design is also a process that is used to systematically solve problems.
3
What is a design process ?
• Design process is a method to solve problems and create things people
want. It's like a step-by-step plan where you come up with many ideas,
but in the end, you choose the best one to meet people's needs.
• There are several design processes used in different technical fields.
• The following is the most common design process practice:
4
1- Define
problem
2- Brainstorm
3- Research &
generate
ideas
4- Identify
criteria and
constraints
5- Explore
possibilities
6- Select
approach
7- Develop
design
proposal
8- Model or
prototype
9- Test and
evaluate
10- Refine
11- Create or
make
12-
Communicate
results
Design Process
5
1- Define a problem
• Receive a problem to solve from the client.
• Gather information.
• Be inspired through media exposure of a current problem and take
action.
6
2- Brainstorm
• Brainstorming is when a group of people
gets together to share and come up with
lots of ideas on a topic. It's a creative and
open-minded way to think of possibilities
without worrying about perfection.
• Develop preliminary ideas.
7
3- Research and generate ideas
• Conduct interview with those who affected by problem.
• Research solutions that may already exist; identify shortcomings and
reasons why they are not applicable to this situation.
• Compile ideas and report findings to the team.
8
4- Identify criteria and specify constraints
• Identify what the solution should do and the degree to which the solution
will be pursued.
• Identify constraints ( i.e., budget and time are typical considerations).
• Draft the design brief.
9
5- Explore possibilities.
• Consider further development of brainstorming ideas with constrains
and tradeoffs.
• Explore alternatives ideas based on further knowledge and
technologies.
10
6- Select an approach
• Review brainstormed information and
answer any lingering questions.
• Narrow ideas down through a voting process,
or by use a decision matrix.
• Decide on final idea, usually through group
consensus.
Decision matrix is a tool to evaluate and select the best
option between different choices.
11
7- Develop a design
proposal
• Making annotated sketches for further
details.
• Make decisions regarding material types
and manufacturing methods.
• Generate computer models to refine the
ideas.
• Produce working drawings so the idea can
be built.
• implement the design in this stage.
Example of initial working drawings for different
design of helmets
12
Example of working drawings for architecture engineering
13
Example of working drawings of a car’s Electrical Circuit for electrical
engineering 14
Example of working drawings of floor plan for interior design engineering
15
Example of working drawings of building footing reinforcement for civil engineering
16
8- Make a model or prototype
• Make models to help communicate with
idea, and study the aspects such as shapes,
form, fit or texture.
• Construct a prototype ( i.e., A a simple and
small test model of an idea) from the
working drawings, so the solution can be
tested.
Example of scaled model prototype
17

3D printing prototype of shoes design
18
9- Design, test and evaluate
• Design experiments and test the prototype in controlled and working
environment.
• Gather performance data; analysis and check results against established
criteria.
• Conduct a formal assessment to flash out areas of concerns, identify
shortcomings, and establish any need for redesign the work.
19
10- Refine the design
• Make design changes; modify or rebuild the prototype.
• Make refinement until accuracy and repeatability of the prototype’s
performance results are consistent.
• Update documentation to reflect changes.
• Get feedback from users to see if the requirements have been met.
20
11- Create or make solution
• Determine custom/mass production.
• Consider packaging.
12- Communicate processes and results
• Communicate the designer’s final solution through media such as Power point,
poster session, and technical report
• Market the product.
• Distribute
21
