What is Design?
|
creating new solutions to problems
|
|
|
What are the challenges of Design?
|
Creativity- new creation
Complexity- making decisions on variables/parameters Choice- choices btw solutions Compromise- balancing requirements |
|
|
What are the design operations?
|
1. explore alternatives
2. formulate models 3. specify components 4. select material |
|
|
What are the steps in product life cycle?
|
1. R&D
2. Market Study 3. Production 4. Intro 5. Growth 6. Maturity 7. Decline |
|
|
What are static products?
|
- incremental change
- customer not eager to change - fashion/styling plays little role - stable no. of large producers - high price competition - little market research - mature/stable technology - industry restrict change - process (not product) research |
|
|
What are dynamic products?
|
- customer drives change
- many small producers - new products with advancing technology - high product differentiation - low industry standardization - product (not process) research |
|
|
What are examples of static & dynamic products?
|
Static - automobiles and consumer products
Dynamic - telecommunication systems and softwares |
|
|
What are the design requirements?
|
1. Physical
2. Aesthetic 3. Performance 4. Cost 5. Manufacturing technology 6. Environmental |
|
|
Whare are the pitfalls of traditional design?
|
- design decisions affect life cycle cost
- process optimisation cannot be made up for careless design - change after design stage is too expensive |
|
|
Whare the phases of technology advancement?
|
1. Invention - idea conceived
2. Innovation - idea practiced/utilized 3. diffusion - innovation widespread initiation |
|
|
Why is design important?
|
- major effect on COST
- QUALITY built into product - determines cycle TIME |
|
|
What is the aim of DFM?
|
- minimise COST
- minimise development cycle TIME - increae QUALITY |
|
|
Whare are the steps of conceptual design?
|
1. id customer needs
2. define problem 3. gather info 4. conceptualize 5. select concept 6. refine PDS 7. review design |
|
|
Whare is embodiment design?
|
- product archictecture
- configuration design - parametric design |
|
|
What are the considerations for planning for manufacture?
|
- process sheet
- design tools - production plant - work schedule & inventory control - quality assurance - standard time/cost - information flow |
|
|
What are the considerations for planning for distribution?
|
- shipping
- shelf life - warehouse arrangement - market exercise |
|
|
What is involved in detail design?
|
- add missing info
- prepare drawings - prepare assembly instructions - build/test prototypes - review design |
|
|
What are the considerations for planning for use?
|
- ease

|
|
What is functional organization?
|
-commong background (expertise)
-economies of scale -formal interaction btw units -slow decsion making -static products |
