Phases of Design
Customer– Understand the Design
Process
Specification Development– Specification of Information
Conceptual Design– Specification of a Principle– Functional Decomposition– Generate Concepts– Concept Evaluation– Concept Selection– Preliminary
Design/Embodiment
Detail Design Specification of Production
– Process Planning
Manufacture

3 Types of Design
Original– New Products– New Ideas (patents)
Adaptive– Known system to a changed
task– ABS, High Performance
Aircraft → Car
Variant – Vary size– Vary arrangement– Same task
• braking truck• braking car
Redesign– Adaptive – Variant – Bulk of Design Work

Design Techniques for all Levels of Design Systems
Plants (Factories) Equipment (Machining Centers) Individual Machines (Lathe …) Assembly (Spindle Motor) Component (Bearing in Motor) Feature (Ball Track in Bearing)
– Something that is fabricated

Energy Material & Information (EMI)
A design converts Energy Material & Information Main function
– Basis for customer requirement– Essential problem– Crux of problem
Need to understand the problem statement Example
– Design Bolted Joint vs. fasten 2 pieces of metal
Function– What you want to do - changes (manipulates) EMI
Behavior– What it does
