CHAPTER 4 - EMBODIMENT DESIGN
ERGONOMIC AND HUMAN FACTOR DESIGN
To optimize human well-being and overall system performance
Understanding interactions among human and products or systems
Objectives
Anticipate human errors
Provide feedback and good display
Stardardization
DESIGN FOR ENVIRONMENT
When product useful life is over
Disposed
Reused
Recycled
Factors
Economics
Less expensive
Customer expection
Consumers are increasingly more aware of the value of recycling
Government Regulation
Forcing attention on the environment
Knows as green design, environmentally conscious design, lifecycle design
PRODUCTION ARCHITECTURE, CONFIGURATION DESIGN AND PARAMETRIC DESIGN
CONFIGURATION DESIGN
Factors
Material selection
Manufacture method
Function
Refining
Less abstract
:More detailed descriptions
Patching
Improvement without changing its function
Design special purpose parts and the selection of standard components, like pumps and motors
PARAMETRIC DESIGN
Tolerances
Tighter
High cost
Less chance for vibration in moving parts
Larger
Low cost
Poor performance
Steps
Find alternative design
Analyze & evaluate
Understand the design problem
Refine & optimize
Objective
Set values for the design variables
Produce best possible design
Considering
Performance
Manufacturability
Example
Shaft & bearing clearances and fit
Determine the exact values, dimensions and tolerances of the components
PRODUCT ARCHITECTURE
Example
L Bracket
Process
Cluster the elements of the schematic
Create a rough geometric layout
Create a schematic diagram
Identify the interactions between modules
Determining the arrangement of the physical elements of the design into groups
DESIGN FOR MANUFACTURE ( DFM )
Methods
Process-driven design
Design of Experiment (DOE)
Taguchi method
Based on minimizing the cost of production including minimizing the time to market while maintaining a hi standard of quality
DESIGN FOR ASSEMBLY (DFA)
The study of the ease of assembling various parts and components into final product
Integrating DFA and DFM helps contribute to the competitive success of products.
With DFA, every parts has to be checked
