  1. Sustainable Product & process development ISQA 511 Dr. Mellie Pullman

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

  3. Sustainability Product and Process Protocols and Frameworks

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

  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)

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

  7. Air= Packaging Space • How does this effect: • Transportation loads • Vehicles • Warehouse • Environment

  8. Design for Environment Flow and Support Tools * Initially, a philosophy or framework may create guiding principles such as C2C or Natural Step

  9. Cradle to Cradle Philosophy Biological Technical

  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

  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.

  12. Fundamental Design Objectives • 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 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 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

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

  15. Life Cycle Analysis Scope

  16. Voice of Customer issues Typical Needs (pick 3) Needs related to Environment (pick 3) • 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 Rate the importance of each on a scale of 1-5 for your 6 items

  17. Engineering Metrics for producers & environmental view Hair dryer EMs(pick 3) Environmental EMs(pick 3) • Air flow • Air temperature • Weight • Hardness • Physical lifetime • Number of parts • Rate of recyclable materials • Rate of standardized components • Number of materials • Amount of energy consumed • Biodegrability • Toxicity of Materials

  18. Looking at your weight-importance scores • What is more important measurement? • What should the producer focus on here?

  19. Other Details of Interest • 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?
