Introduction (Definitions and abbreviations)

Introduction (Definitions and abbreviations) PLM: Product lifecycle management STEP: Standard for the exchange of product model data Eco-Design A design approach for product design Special consideration is given to a products environmental impact during its whole lifecycle. ”Reduces adverse impact of products on the environment, right from the early stage of design and throughout the entire product lifecycle.”

Introduction (Chapter 3) Computer aided sustainable design: How designer and CAD applications can reduce damage of products and the environment. Content in general: Today’s impact of computer aided design (CAD) on Eco-Design processes and how they can be improved in the future. How a product designer should organize and plan his/her design Which features should be implemented in CAD and Eco-Design applications in order to simplify a designer’s daily work.

How CAD affects today’s environment CAD Feature Benefit Environmental impact Virtual prototypes and simulation Less need for physical tests & prototypes Less wasted materials Concurrent engineering Less need for traveling Less fossil fuel usage & CO2 emissions Modeling Less paper usage Less tropical deforesration → decreace in CO2 emissions → mitigating climate change Less energy, water and chemical usage. Ability to visualize Faster/better communication → Speeds things and minimizes a need for rework Natural resources are utilized more efficiently Ability to run CAD applications in mobile devices Ability to work outside Potentially less energy used by appliances in home/office

How CAD affects today’s environment (Concurrent engineering) Concurrent engineering design approach All phases of manufacturing operate simultaneously. Product and process design run parallel

How CAD affects today’s environment (Concurrent engineering) Overall benefits Reduce in product development costs Improves communication Less traveling Increases in overall product quality 30 to 40 % reduction in project times and cost 60 to 80 % reduction in design modification after product release Environmental impact Less fossil fuel usage and CO2 emissions

How CAD affects today’s environment (Virtual prototypes & simulation)

How CAD affects today’s environment (Modeling) In the past information was retained mentally or written down to piece of papers Component collisions Supply of incorrect quantities of parts Incorrect sizes of parts Nowdays information is saved in model files Models can be directly forwarded to CAM applications and CNC machines. No need for paper Easy to edit Models retain their integrity
