Make the brief specific
A drawing shows geometry. Add the loads, temperature exposure, contact conditions and assembly method to show what the part needs to do.
Keep packaging connected to the route
The pack sees loading, storage, transport and unloading. Define the vulnerable surfaces and handling conditions before comparing protective formats.
Use recovery as a design input
Local collection, separation and reuse arrangements influence a realistic end-of-life strategy. Discuss these alongside the initial product design.
