2 Overview  Design for “…”  Protocols  Herman Miller Case  Tool Demonstration  EQFD (QFDE) 2

3 Sustainability Product and Process Protocols and Frameworks 1970s & 1980s Pollution Control Pollution Prevention 1990s Eco-Efficiency Design for Environment The Natural Step Industrial Ecology 2000s Cradle to Cradle Life Cycle Analysis Biomimicry 3

4 Design for…  Manufacturing and Assembly  Disassembly  Recycle  Reuse  Logistics  Or Design for Sustainable Supply Chain Management 4

5 Sustainable Design & Supply Chain  Aspects of sustainability can pervade all design activities affecting the product during its life time:  Social, economic, and environmental aspects of Raw materials Production Packaging Transportation Redistribution Disassembly Recycling  Measures (Carbon Footprint, LCA, energy, water, etc.) and Methods (EQFD) 5

6 Internal competition to reduce unnecessary air in their product packaging to lower logistics cost and increase efficiency in transportation and warehouse Example: Ikea’s Air Hunting Competition Glimma tea candle 6

7 Air= Packaging Space  How does this effect:  Transportation loads  Vehicles  Warehouse  Environment 7

8 Design for Environment Flow and Support Tools DfE Project Development* Project Concept Development (QFDE Tool) Conceptual Design Qualitative design review on sustainability aspects Design Detail Quantitative design review on sustainability (LCA) Production * Initially, a philosophy or framework may create guiding principles such as C2C or Natural Step 8

10 Environmental Quality Function Deployment  Quality Function Deployment is a product development tool that comes out of Japan (House of Quality)  Typically used to optimally meet customer needs  Converts their needs (CN) to measurable engineering characteristics/metrics (EC/EMs)  Targets are then set for EC/EMs  Second stage translates the EC/EMs to specific components parts and design features. (third and forth stage sets up manufacturing process and production process)  EQFD accounts for environmental needs and characteristics 10

11 Why use this tool?  Team approach: pulls designers, marketing, engineers, and process development people together to look at the impact of their decisions on the final product,  Systematic: considers environmental impact of design choices & alternatives in an orderly way,  Sequential development: customer & environmental needs are considered up front and trickle through system,  Customer & environment needs, engineering metrics, components, manufacturing process, & production process.  Proven track record of success with new product development. 11

12 Fundamental Design Objectives 12  Maximize customer satisfaction (using customer and other stakeholders)  What are the customers needs for the product both functionally and environmentally?  Minimize cost of use  Minimize environmental impacts

13 Sample of Environmental Needs and Engineering Metrics Environmental Needs  Less material usage  Less energy & water consumption  Easy to transport and store  Easy to process and assemble  High durability  Easy to reuse  Easy to disassemble & sort  Easy to maintain  Easy to compact  Safe to incinerate  Easy to dispose of or safe to landfill  Harmless to biosphere  Safe emissions Environmental Engineering Metrics  Weight  Volume  Number of parts  Variety of materials  Likelihood of getting dirty or oxidizing  Hardness  Physical lifetime  Energy consumption  Rate of recycled material  Sensory impact (noise, visual, etc.)  Emissions mass (air, water, soil)  Biodegradability  Material Toxicity 13

14 Class Demonstration of EQFD  EU direction requires EuPs to incorporate life- cycle-based environmental considerations into product development process  Other criteria that you should consider? EuP: Energy Using Products Green Product Design for Hairdryer 14

15 Life Cycle Analysis Scope Extracting & processing raw materials Manufacturing Packaging Transportation & Distribution Useful life, maintenance & reuse Recycling Disposal at end of life 15

16 Voice of Customer issues  Dries quickly  Quiet  Comfortable to hold  Less energy consumption  Operates easily  Reliable  Portlable  Easy to disassemble  Easy to smash  Easy to sort  Easy to recycle  Safe to incinerate  Safe to landfill Typical Needs (pick 3) Needs related to Environment (pick 3) Rate the importance of each on a scale of 1-5 for your 6 items 16

20 Looking at your weight-importance scores  What is more important measurement?  What should the producer focus on here? 20

21 Other Details of Interest 21  Are any of these related factors (roof of house)?  What problems or opportunities might this reveal?  Right side of house and basement, competitor’s situation > strategic insights?
