What is Engineering Design?

• In order to create and build things, engineers
  must be involved in a design process
• ABET definition of design
• the process of devising a system, component, or
  process to meet desired needs

2
Chapter 13 Engineering Design Section 13.2 The
Design Process

• 10 Stage Design Process
• Identify the problem / product innovation
• Define the working criteria / goals
• Research and gather data
• Brainstorm / Generate creative ideas
• Analyze potential solutions
• Develop and test models
• Make the decision
• Communicate and specify
• Implement and commercialize
• Perform post-implementation review / assessment

3
Chapter 13 Engineering Design Section 13.2 The
Design Process

• Stage 1 Identify the problem / product
  innovation

• It is critical to establish the actual problem
  clearly
• Less likely to be an issue in an academic
  setting, where the professor provides structure
• In industry settings, very important to clarify
  what the problem is before attempting to solve it

4
Chapter 13 Engineering Design Section 13.2 The
Design Process

• Stage 2 Define the working criteria / goals
• Examples of working criteria include
• How much will it cost?
• Will it be difficult to produce?
• What will be the size, weight, strength?
• What will it look like?
• Will it be easy to use?
• Will it be safe to use?
• Are there any legal concerns?
• Will it be reliable and durable? And more

5
Chapter 13 Engineering Design Section 13.2 The
Design Process

• Stage 3 Research and Gather Data
• Having good, reliable background information is
  necessary for the team to begin exploring all
  relevant aspects of the problem
• Team members must determine
• What types of information will be needed
• The best sources of that information

6
Chapter 13 Engineering Design Section 13.2 The
Design Process

• Stage 3 Research and Gather Data
• Examples of research/data gathering include
• What information has been published about the
  problem?
• Is there a solution to the problem that may
  already be available?
• If there is an available solution, who is
  providing it?
• What are the advantages / disadvantages of their
  solution?
• What is the cost? Is cost a significant issue?
• What is the ratio of time spent compared to
  overall costs? And more

7
Chapter 13 Engineering Design Section 13.2 The
Design Process

• Stage 4 Brainstorm / generate creative ideas

• Brainstorming to creatively develop as many
  potential solutions to a problem as possible
• Every idea that is spontaneously contributed from
  the group is recorded
• No preliminary judgments are made about any
  members idea, no matter wild that idea may be
• Goal to develop a long list of possible
  alternative solutions to the problem at hand.

8
Chapter 13 Engineering Design Section 13.2 The
Design Process

• Stage 5 Analyze Potential Solutions

• Once brainstorming ideas have been narrowed,
  further narrowing to a few ideas can be
  accomplished by
• Examining the list and eliminating duplicates
• Allow the group to ask clarifying questions
• Ask the group to evaluate the ideas.

9
Chapter 13 Engineering Design Section 13.2 The
Design Process

• Stage 5 Analyze Potential Solutions

• Forms of analyzing potential solutions include
• Common Sense
• Economic Analysis
• Analysis using basic engineering principles and
  laws
• Estimation
• Analysis of compatibility
• Computer Analysis techniques
• Conservative Assumptions

10
Chapter 13 Engineering Design Section 13.2 The
Design Process

• Stage 6 Develop and Test Models

• Brainstorming and further Analysis have narrowed
  options to just a few. The remaining options
  will now be developed and tested.
• Models used by engineers to develop and test
  include
• Mathematical models
• Computer models
• Scale models
• Diagrams or graphs

11
Chapter 13 Engineering Design Section 13.2 The
Design Process

• Stage 6 Develop and Test Models

• Testing Prototypes will help determine
• Durability
• Ease of assembly
• Reliability
• Strength
• Environmental
• Quality consistency
• Safety
• Consistency of testing

12
Chapter 13 Engineering Design Section 13.2 The
Design Process

• Stage 7 Make the Decision

• Team members must establish a means to compare
  and evaluate the results from the testing stage
• Common Method Used to Make the Decision
• Decision Table
• Helps members to visualize the merits of each
  option)
• Decision Table Columns include (a) Working
  Criteria, (b) Weighted Point Totals, (c)
  Individual Point Totals

13
Chapter 13 Engineering Design Section 13.2 The
Design Process

• Stage 8 Communicate and Specify

• Before manufacture of a part/ product/ structure,
  there must be thorough communication, reporting
  and specification of all aspects of that item
• Types of communication include

• Written Reports
• Summaries of technical presentations
• Diagrams

• Drawings / Sketches
• Computer Printouts
• Charts
• Graphs

14
Chapter 13 Engineering Design Section 13.2 The
Design Process

• Stage 9 Implement and Commercialize

• Next-to-last stage of the design process
• Final Opportunity for revision (or termination)
  of project
• Project manager, team leaders and the following
  key individuals are involved in this step
• Management / Key Supervisory Personnel
• Technical Representatives
• Business Representatives
• Attorneys / Legal Support Staff

15
Chapter 13 Engineering Design Section 13.2 The
Design Process

• Stage 10 Perform Post-Implementation Review and
  Assessment

• At this stage, project is assumed to be in full
  production
• This stage involves the termination of the design
  project team (since the product is now part of
  the companys overall product line).
• Products performance is reviewed, an assessment
  report is prepared, and future suggestions
  provided
