Considera;on of a Good Design •  What makes a good design? Review: Different Views of Design •  A simplified itera;on process (Fig. 1.2) •  Design method vs. Scien;fic method •  A problem ­solving methodology; Descrip;on of Design Process •  Phase I: •  Phase II: Q: What are the tasks to accomplish? Phase III of the Design Process: Detailed Design •  A complete engineering descrip;on of the design; •  A specifica;on for each special ­purpose part and standard part; •  Tasks: Descrip;on of Design Process Phase V: Planning for manufacturing Q: What are the tasks? Descrip;on of Design Process Phase V: Planning for distribu;on Q: What are the issues? Phase VI: Planning for use Q: What is the problem to address? Q: What are the problems should be considered? Descrip;on of Design Process Phase VII: Planning for re;rement of the products Before: Now: Why do we care? CAE The driving force: A bit of history: What is the greatest impact on design? What are the benefits? (surface quality op;miza;on); Concurrent Engineering Overlapping & Concurrent manner; Key technology base: What can CAE help us in design? Concurrent Engineering Example: Design of Boeing 777 Design for Codes & Standards Ques;on: Why do we need codes & Standards? What is code? What is standard? What are the difference? Design for Codes & Standards What are the different types of codes? Example: How to categorize standards? Examples: Why do companies follow standards? What is the biggest factor in saving? GT: ...
