Electrical Product Design Review: Microwave

WRAP’s free design reviews and follow-up support use product teardown to investigate opportunities where product re-design could improve profit, reduce costs and reduce environmental impact.

This case study describes a product design review of an own brand domestic 800W, 20 litre capacity microwave for a major retailer. Various cost saving opportunities were identified and annual savings, per 100,000 sales per year, were estimated to be:

  • ~ £320,000
  • ~300 tonnes of CO2e

These savings would be through reduced product returns and ways to make the product in a more cost effective manner without compromising quality.

Key opportunities:

  • specify lighter components to reduce the materials used in manufacture;
  • simplify design with fewer components to reduce assembly time;
  • modify the design to improve durability of components with the potential to fail;
  • use more recycled plastic in concealed plastic parts;
  • specify more energy efficient components; and
  • review packaging design for better pallet loading and utilisation of shipping containers.
