11 Lecture 1 Introduction to Design Engineering

22 What is Design? A process of formulating a solution to a problem to satisfy/fulfill a set of criteria/requirements

33 Why study the design process? Right process yields right results Effective design process affects product cost product quality time to produce

44 Design Process vs. Design Methods Design Process – a series of processes involving identification of needs, planning, setting up specifications, conceptualization and product development Design Methods – the techniques employed during design process

55 Design: a Multidisciplinary activities Materials Marketing Avionics Aeronautical Testing Government Electrical Mechanical Production Software

66 How do we cope? Sequential/Traditional Concept Customers Marketing Production Engineering Design Concurrent Design Concept  Team work  Team work – Design, Manufacturing, Customers, Marketing & Sales, Vendors  Tools and Techniques  Tools and Techniques – CAD, Design Process best practices, Paper and pencil  Product and process information  Product and process information – requirements, concepts, products, phases of PLC, Manufacturing process plan, Design process plan

77 Design Process: WHERE and WHEN Complex design environment Complex design environment – multidisciplinary and complex tasks e.g. Automotive, Aerospace, Marine, Building. Systematic approach and methods – Systematic approach and methods – Taguchi’s, Pugh’s, Pahl & Beitz, or Design Best practices. Can we do without? Risk of product failure Risk of product failure – miscalculation in design World is becoming more competitive World is becoming more competitive – issues of time to market, product quality, leading edge

88 Knowledge in Design R&D R&D - vital element in design. Knowledge is POWER Engineers play significant role, e.g. Automotive – VVT, AC module, GIS Computer/IT – new hardware Advanced Materials Micro engines Satellite technology
