Topic 12.1: Design for manufacture Questions

Draw two fastening methods, one that allows disassembly and one that does not, labelling each.

A sensor’s internal chassis is keyed so it fits its housing in just one orientation. What strategy is applied?

Outline how design for disassembly can reduce waste from a desk organiser made of timber and metal.

Explain how three DfM strategies could reduce the environmental impact of a reusable storage crate. Consider these proposals: use suitable ribs instead of solid thick moulded sections; combine fixed dividers where function permits; use releasable hinges and separable labelled polymers.

Which approach includes designing a lamp for its making process, component assembly and later disassembly?

A toy housing combines two fixed brackets into one moulding and uses fewer fitting operations. What strategy is being used?

A drawing review asks how a product is made, put together and taken apart. What is the review applying?

A redesign of a watering can means its handle and body are formed as one part. Outline one way this can reduce manufacturing costs.

A proposed community tool stand uses locally available timber sections, straight cuts and drilled holes made with existing workshop tools, and standard bolts joining pre-drilled modules. Explain how these choices suit available materials, the manufacturing process and assembly.

A flat-pack stool uses identical bolts, pre-drilled panels and one assembly tool. Which strategy do these choices demonstrate?

Outline how design for disassembly can extend the life of a portable radio when its battery fails.

A redesign of a desk organiser means its dividers and base are one moulding. Outline one way this can reduce manufacturing costs.

A redesign of a cable guide means its mounting bracket and clip body are one moulding. Outline one way this can reduce manufacturing costs.

Outline how design for disassembly can extend the life of a desk fan when its switch fails.

Outline how design for disassembly can reduce waste from a cycle light made of polymer and aluminium.

Explain how three DfM strategies could reduce the environmental impact of a modular garden bench. Consider these proposals: cut repeated boards efficiently from standard stock; use a small number of repeated fittings; attach weathered slats with accessible screws.

Outline how design for disassembly can reduce waste from a display frame made of steel and fabric.

List two design features that would make a modular stool easier to disassemble.

Outline two design-for-disassembly aspects that could extend the service life of a modular stool.

A fan casing uses accessible screws so its motor and plastic can be recovered separately. Which strategy is shown?
