- Design methodology and human factors Linear (systematic) and iterative design; user-centred design; inclusive design; biomimicry; design thinking (empathise, define, ideate, prototype, test).
- Materials science and selection Metals (ferrous, non-ferrous, alloys), polymers (thermoplastics, thermosets, elastomers), woods and manufactured boards, ceramics and glass, composites (GRP, carbon fibre, reinforced concrete), and smart materials (shape-memory alloys, thermochromic and photochromic materials, piezoelectric materials).
- Manufacturing processes One-off, batch, mass and continuous production; just-in-time; flexible manufacturing systems.
- Structures and mechanisms Frame and shell structures; forces: tension, compression, shear, bending, torsion. Triangulation; reactions at supports; simple beam calculations using moments; factor of safety = ultimate stress ÷ working stress.
