Card 1concept

Question

What is the key question in design for disassembly?

Answer

What fails first, and how deep is it buried? In almost every powered product the answer is the battery.

Card 2concept

Question

Name four changes that improve disassembly.

Answer

Screws or released clips instead of adhesive; the shortest-lived part reachable first; one fastener type throughout; and materials marked and not bonded together.

Card 3concept

Question

Why is repair the largest environmental saving?

Answer

It avoids a whole new product — all its extraction, manufacture and distribution. No material substitution comes close.

Card 4concept

Question

Why is design for disassembly often ignored?

Answer

It costs assembly time on every unit, paid by the manufacturer, for a benefit somebody else receives years later — which is why it is regulated.
