This core content provides the foundational knowledge for Design Technology, focusing on the integration of manufacturing and engineering principles within the design cycle. It explores how designers and engineers consider human factors, sustainable practices, material properties, and production techniques to create effective solutions. The practical application involves analysing products, developing design proposals, and employing modelling and prototyping to refine concepts.

Examiner Tips

Expert advice for maximising your marks

💡Always reference specific anthropometric data sets (e.g., 5th percentile female) when discussing ergonomics.
💡Structure answers using the design cycle: investigate, design, plan, create, evaluate.
💡Use clear, annotated diagrams and sketches to support explanations.
💡In evaluation, balance benefits and limitations rather than providing only positive aspects.
💡For data-based questions, show calculations and units explicitly.

Common Mistakes

Pitfalls to avoid in your exam answers

Confusing ergonomics with anthropometrics, or failing to use specific anthropometric data.
Overlooking the full lifecycle assessment, focusing only on materials and not end-of-life disposal.
Producing CAD models that lack proper constraints or realistic dimensions.
Assuming one manufacturing process is universally optimal without considering batch size or material limitations.
Neglecting user feedback in the design iteration process.
