Question 1 Report

Fig. 1 shows two designs for the same hand tool. Design A is assembled with screws and Design B is glued and welded.

Explain how each design affects repair and recycling at the end of the product's life. [4]

Answer

Answer Details

Design assembled with screws: screws can be removed with a common tool, so a worn component can be replaced and the tool can remain in use for longer. [1] At the end of its life, the assembly can be opened and different materials can be separated into the correct recycling streams. [1]
Design glued and welded: permanent joints cannot normally be opened without damaging or destroying the product. A failure in one component can therefore end the life of the complete tool. [1] The joined materials cannot be separated economically, so the product is likely to be landfilled or shredded as mixed waste rather than effectively recycled. [1]

Removable mechanical fixings support repair and material separation; permanent joints obstruct both. [4]
