OCR Engineering Design Level 1/Level 2 (J822) Past Papers

Engineering Design assignments at Distinction level require systematic design methodology, not just creative output. A design specification should contain quantifiable criteria: dimensions (not 'small' but '200mm × 150mm × 50mm'), material requirements (not 'strong' but 'withstand 50N load without permanent deformation'), cost constraints, user requirements, and sustainability considerations. Each criterion should be measurable — this makes design evaluation objective rather than subjective. Engineering drawing communication requires knowledge of conventions. Third angle projection (used in the UK and USA) places the front view top-centre, the plan view below it, and the end view to the right. First angle projection (European standard) places views in opposite positions. Always state which standard you are using. Dimensions should be placed outside the object, not through it; use leader lines for small features; include a title block with part name, material, scale, and drawing number. Design evaluation is a reflective process that should compare the final design against each criterion in the original specification. Use a structured evaluation table: list each specification criterion, measure or test whether the design meets it, and identify improvements. Distinction-level work evaluates through multiple methods (physical testing, user feedback, virtual simulation) and proposes specific, technically justified modifications — not 'make it better-looking' but 'increase the wall thickness from 2mm to 3mm to prevent buckling under the specified 50N load'.
