Transcript of The Design Cycle

@ United Nations International School, Hanoi, Vietnam.
Inquiry &
Analysis

1. Explain your DESIGN PROBLEM.
2. Write your GUIDING QUESTIONS & RESEARCH STRATEGY.
3. RESEARCH relevant information to solve the problem.
4. BRAINSTORM ideas & write your DESIGN BRIEF.
Developing
Ideas

Creating
the Solution.

Evaluate
The Product Design
Design Cycle

Parts List
Make a list of all of the parts in your design. Include sizes, materials, quantity, and the tools & machinery required to manufacture your design.
Step-by-step
Plan of Manufacture
Explain in a sequence of instructions all of the steps required for you to create your design. List any tools & machinery, and explain all the processes used.
Gantt Chart
Produce a Gantt Chart to plan out the timing of manufacture.
Specification
Write a Design Specification to clarify what your design must have, do, look like...
Consider size, ergonomics, function, aesthetics, target market, design features, location of use, environmental issues, material choice, construction methods, finishing processes... etc.
Design Ideas
Draw a range of design ideas using
a variety of drawing techniques.
Be sure to Analyse & Annotate each design.
Analyse
- What are all of the good points, bad points, and how can you improve each?

Annotate
- Fully explain all of the parts of your designs to ensure they are easily understood.
Evaluate each design against your
design specification
Look back at your design specification. Is it the same? If not, why...?
Final Design
Now produce a final design. It can be an improved version of one of your design ideas, or a completely new design.
Draw your design in 3D, add colour & shading, annotate thoroughly, justify your choice of final design, and evaluate it against the design specification.
3D View
Exploded View
CAD
Justification of your Final Design
Why did you choose this as your final design?
Google Sketchup Tutorials
Pro-Desktop Tutorials
2D Design Tools Tutorials
(Computer Aided Design)
Evaluate your Final Design against the Design Specification
Look back at your design specification. Is it the same as your final design? If not, why...?
2. Create your design to the best of your ability.
1. Produce a work plan to create your design.
Orthographic Drawings
Draw a detailed front view of your design including all measurements.

2. Evaluate your design against your design specification based on testing.
Evaluate your design against your Design Specification
Does it meet your Design Specification? If not, why not?
Testing from the End User
How has your design had an impact on the end user?
Modifications to your design
Now that you have evaluated your design explain how you would improve it?
Draw your improved design/modifications.
Has it changed their life for the better? If so, how?
Give evidence of the testing - Photos, names, dates...
Self Assessment
Get your peers to assess your design.
What do you think about your peers' comments?
3. Follow your work plan to complete your design.
1. Perform relevant & thorough testing to measure the success of your design.
3. Explain how your design can be improved?
4. How did your design impact the end user?
Test your design in its intended place,
by the intended user.
Your choice of peers should be relevant. Eg: Do not have students in your class give you feedback if you designed a chair for your family. Your family should provide you with this feedback.
Design Problem
Explain the need, or the problem you are trying solve. Who is the product for? Is it for a specific person or a target market? Why do they need it? How will it help them? Why did you chose this project? How did you come up with the idea?
Explain how you intend to solve your Design Problem.
Brainstorm
Do a Brainstorming activity to identify all of the important aspects of your design.
Research Plan
Create a table to plan all of your research. Explain how, when, why and what you will research.
Research Existing Designs:
Research according to your Research Plan.
Why did you choose these designs?
What are the good & bad features of each design?
How can you improve each design?
Guiding Questions
What information do you need to find out to help make your design?
A good starting point is to consider all of the things you do not know about your project.
Ensure all questions are open - meaning there cannot be Yes or No answers.
Ask mostly "How" or "Why" questions.
Summarize all of the information you gathered.
Research -
Interview:
Interview your end user, or an expert in the area to find out exactly what is required for the design.
Research - Real World:
Take some photos
Disassemble existing designs, or other similar items which are suited to your design.
Photographs
Research
Anthropometrics
What measurements on the human body are related to your design?
Write down some key words then ellaborate on them to fill your page with many different ideas.
Add colours, shapes and pictures to make it look great and to create more ideas.
Conclusion
Bibliography
Write a conclusion at the end of every section of your research.
What have you learnt from this research?
What decisions have you made based on your research?
Take measurements related to your design
Keep a record of all of your sources of information.
Analyse your research
Photographs
