Top Exam Board Tips
- When asked to redesign a product for ease of assembly, systematically reduce the number of separate parts by combining functions where possible, and justify each change with a clear rationale linked to reduced assembly steps.
- Always refer to standard DFMA guidelines, such as minimizing fasteners, using symmetric parts to avoid orientation errors, and designing parts that are self-aligning, as these are well-recognised in mark schemes.
- For material and process selection questions, use a structured approach like a decision matrix or property charts and explicitly mention trade-offs between cost, performance, and manufacturability.
- In coursework, document your DFMA analysis with both initial and improved assembly sequence diagrams, quantifying time savings or cost reductions where possible to strengthen your evidence.
- Always document your design journey: a logbook showing the iterative process, including failures and refinements, demonstrates application of design thinking.
- Use a combination of communication methods: quick freehand sketches for initial ideas, detailed orthographic projections for manufacture, and physical models to test ergonomics.
- When presenting models, explain how they connect to the design specification and user requirements, highlighting key features and materials.
- Use the PESTLE (Political, Economic, Social, Technological, Legal, Environmental) framework to ensure all relevant influences are considered in extended answers.
- When referencing legislation, state the full name and, if possible, the specific regulation number (e.g., Regulation (EU) 2023/1230) to demonstrate precision.
- Embed real-world case studies—such as the development of medical devices under MDR 2017/745 or automotive design shaped by Euro NCAP safety ratings—to illustrate the interplay of influences and constraints.
Common Mistakes to Avoid
- Confusing design for manufacture with design for assembly: students often focus solely on how parts are made rather than how they are assembled, or vice versa.
- Overlooking the impact of tolerances: assuming parts will always fit perfectly without considering tolerance stack-ups that can complicate assembly.
- Selecting materials based only on mechanical properties without evaluating their formability, machinability, or joining characteristics, leading to impractical production plans.
- Neglecting to consider the entire product lifecycle, such as disassembly for maintenance or recycling, when proposing design simplifications.
- Students often skip the empathy phase, leading to solutions that do not address actual user needs.
- Misinterpreting design thinking as a linear process rather than an iterative loop, resulting in a lack of refinement.
- Inadequate communication: providing sketches without annotations, dimensions, or material specifications, making it hard to interpret the design.
- Confusing social factors with cultural ones: e.g., treating affordability (economic) as a social trend rather than a purchasing power issue.
