The Design Process

1
The Design Process

• Drawing And Design For Production
• Engineering

2
What is Designing?

• It is simply translating ideas into reality.
• It is a technical form of problem solving.
• Provides a plan to create, implement, evaluate,
  and improve a product or process.

4
Identify the Problem

• Identify and define the problem.
• This step involves investigating the needs and
  opportunities.
• The problem must be real and clearly stated.

• survey/market research
• accident
• complaints
• need identified

5
Framing a Design Brief

• Develop the Design Brief
• This step involves clarifying the results you
  want to achieve
• Stating pre-determined Specifications and
  criteria such as time, cost, size, shape,
  materials, users, place of use, and special
  functions should be listed.

6
Design Brief( 2 Parts )

• Give an introduction to the solution that you
  plan to implement. Restate the identification in
  a manner that reflects a solution.
• List anticipated specifications and guidelines
  that the solution must follow.
• This step often leads back to redesign of part or
  all of the solution and the process begins again.
• Tests should be conducted on models and prototype.

7
Investigation and Research

• Gather all pertinent information for future
  reference.
• This step should involve the following resources
• Human factors
• Ergonomics
• Existing devices and systems
• Existing knowledge and solutions

8
Generating Alternative Solutions

• Explore possible solutions.
• This stage involves brainstorming and ideation.
  (some initial sketching of thumbnails is needed)
• This step involves searching for solutions and
  information.
• Several different solutions should be explored.
  Investigation may help clarify need or problem.

(Brainstorming)
(Thumbnails)
9
Brainstorming

• Record your thoughts and ideas with quick notes
  or sketches.
• Discuss these with your team members.
• Record any tangent concepts .
• Investigate any additions, sources, or ideas
  discussed.
• All solutions and ideas are welcome.

10
Thumbnail Sketches

• Recorded ideas with quick sketches
• Initial ideas with little thought to scale or
  accuracy
• Can include some initial notes or ideas.

11
Choosing the Optimal Solution(s)

• Assess the alternatives.
• Refinement of preliminary ideas. Annotated
  Sketches
• This step involves assessing all the solutions
  generated and choosing the best one(s)
• Implement the Design Matrix
• The best choice or choices move on to step 6

12
Annotated Sketches

• Refine your preliminary thumbnail sketches.
• Add notes and comments
• Weigh your specifications

13
A Design Matrix

• Using a matrix, select a workable solution

14
Developmental Work

• In this step you will further develop your
  optimal choice(s).
• More support research
• You will develop your initial drawings.
• This step involves experimentation with
• different materials
• mechanical systems (kinematics)
• Fastening techniques
• Shapes and sizes
• preliminary models

15
Drawings

• Working Drawings
• Assembly Drawings
• ( Choose one of the above )

16
Working Drawings

• A drawing that supplies information and
  instructions for the manufacture or construction
  of machines and structures.
• Typically shows individual views of the object.

17
Modeling and Prototyping

• The last stage of a product prior to testing and
  production
• This step involves the development of models, and
  prototypes.

(Types of Models)
18
Prototyping of Design Solutions

• Models are used as representations of system
  design for refinement and testing of the product.
  (3 types)
• Appearance - Looks like Model
• Function - Works Like Model
• Prototype - Looks like Works like Model

19
Testing And Evaluation

• Evaluate the results.
• This step involves testing the solution and
  assessing the process.
• Demographic testing
• Survey groups
• Scientific testing and analysis

20
Assembling Drawing

• A drawing showing the product in its completed
  state.
• An exploded assembly is a very common type of
  assembly drawing. It shows the individual pieces
  of the object unassembled, and it shows the
  pieces aligned to each other demonstrating how to
  assemble the object.
