Q

Describe the design process in terms of two sets of three simple stages.

A

A simple (3-stage) description of the design process proceeds as:

  1. Generation of alternatives
  2. Evaluation of alternatives
  3. Communication of the selected design

Three phases of the design process proceed as:

  1. Conceptual Design
  2. Preliminary Design
  3. Detailed Design
2
Q

Map out the design process.

A
4
Q

Describe Conceptual Design.

A

Conceptual design: seeking concepts or schemes that might be applicable to realizing the client’s objectives. A concept is an outline solution to the problem.

5
Q

Describe Preliminary Design.

A

Preliminary design: proposed concepts are “fleshed out”:

  • The most important attributes of the design identified.
  • Key aspects are sized and selected.
  • Some performance specifications are clearly tied to the design.
  1. Model and analyze chosen design
  2. Test and evaluate chosen design
6
Q

Describe Detailed Design.

A

Detailed design: Refinement of the preliminary design, including selection of all parts and dimensions.

  1. Refine and optimize chosen design.
  2. Assign and specify design details.

The result is usually a set of documents and drawing such that another person or company can complete the design without further contact with the designer (enables replication).

7
Q

Map out the three phases of the design process.

A
8
Q

Organize the activities of the design process into the phases of the design process.

A
9
Q

Outline the steps (1-4) involved in defining the problem.

A

Problem Definition (or Framing) proceeds as follows:

  1. Clarify objectives.
  2. Establish metrics for objectives.
  3. Identify constraints.
  4. Revise client’s problem statement.
10
Q

Outline the steps (5-10) involved in conceptual design.

A

Conceptual design proceeds as follows:

Step 5: Establish functions.

Step 6: Establish requirements (function specifications).

Step 7: Establish means for functions.

Step 8: Generate design alternatives.

Step 9: Refine and apply metrics to design alternatives.

Step 10: Choose a design.

11
Q

Outline the steps (11-12) involved in preliminary design.

A

Preliminary design proceeds as follows:

Step 11: Model and analyze chosen design.

Step 12: Test and evaluate chosen design.

12
Q

Outline the steps (13-14) involved in detailed design.

A

Detailed design proceeds as follows:

Step 13: Refine and optimize chosen design.

Step 14: Assign and fix design details.

13
Q

What critical step (step 15) is involved in design communication?

A

Step 15: Documentation of final design is the backbone of design communication.

14
Q

What processes are involved in documentation for the final design?

A
  • Report
  • Drawings
  • Fabrication Specifications
15
Q

Map out the feedback and iteration involved in the design process.

A
