Organizing Product design and development :Transition of design into manufacture

1. Organizing Product design and development :Transition of design into manufacture by T.A.C: Garth Alexander Althea Smith Babatunde Olubando Chiwuzie Odunukwe

2. Product Design, Why? Many companies have problems in making a successful transition from the design and development concept into a full-scale product manufacture. Some of the major problems include:

3. Product Design, Why? Deficiencies in product design. Delays for modification. Outsourcing of product parts.

4. Producibility analysis and Parallel working Producibility analysis has become an important tool in evaluating the viability of a product design. If carried out before the pre-production phase, it can be very effective.

5. Producibility analysis and Parallel working Some indirect cost incurred during the creation of a part are: The documentation. Process planning . Procurement. Quality assurance. Production control. Storage and distribution.

6. Producibility analysis and Parallel working An integrated system where all members of the design team can collaborate will help reduce and manage the bottleneck in the process.

7. Producibility analysis and Parallel working Product planning considering real customer needs to be included in the design process. This reduces losses for rework or “built-to order” parts for different customers were the manufacturing environment was not built for that purpose.

8. Simultaneous Engineering The incorporation of the design and development of the product and the actual manufacturing process is a major focus of simultaneous engineering. Its benefits are: Products arrive to market in a shorter time. More features are incorporated in the product at a lesser cost. More new products are produced more often.

9. Design For Manufacture and Assembly (DFMA) This is a systematic method of analyzing a proposed design and establishing methods of saving manufacturing and assembly costs. Some typical benefits of this method are: component part reduction of 30%. Assembly cost reduction of 40%. Overall product cost reduction of up to 35%.

10. Robust design and Taguchi Methods Robustness is the ability of a product to work well in a wide range of operating conditions. Dr. Taguchi's system of quality engineering includes consideration of tolerance design, process parameter design and various quality controls.

11. Robust design and Taguchi Methods The approach typically: identify key controlling parameters (set up, components, suppliers etc) separate these into the crucial few and the less important many reduce the variation of the important parameters by redesign, parameter design and tolerance design open up the tolerance on less important parameters to reduce costs.
