How do designers analyse and disassemble existing products to learn from them?
Product analysis and product disassembly: evaluating an existing product against function, materials, manufacture, ergonomics, aesthetics, sustainability, cost and market, and taking products apart (reverse engineering) to understand construction and inform new designs.

What this dot point is asking
OCR wants you to explain how a designer analyses an existing product and how disassembly (reverse engineering) reveals its construction, and how both inform a new design. Learning from existing products is a core part of the explore stage and of Component 02.
What product analysis evaluates
The exam reward is linking each analysis strand to how it improves the new design, not just describing what analysis looks at.
Product disassembly (reverse engineering)
Turning analysis into a better design
The limits and risks
Disassembly is destructive (the product may not reassemble), it shows how but not always why a decision was made, a single example may not be representative, and copying a competitor's design raises intellectual-property and ethical issues. A good answer uses analysis to learn and improve, checks findings against other evidence, and respects intellectual property.

OCR 20196 marksExplain how analysing an existing product can help a designer develop an improved version. Refer to at least three things the analysis would consider.Show worked answer →
A Component 02 question marked by points within a levels structure. Markers reward developed analysis points tied to improvement.
Award marks for any three, developed: analysing function shows what the product does well and where it fails, so the new version can fix the weaknesses; analysing materials and manufacture (often by disassembly) reveals what it is made of and how, so the designer can choose better materials or a cheaper process; analysing ergonomics shows whether it fits and is easy to use, so the new version can improve grip, reach or clarity; analysing sustainability shows the materials, repairability and end of life, so the new version can be more recyclable or repairable; analysing cost and market shows the price point and competitors, so the new version can be positioned and priced viably. Each strand of analysis directly informs a specification criterion for the improved product.
A common dropped mark is describing what analysis looks at without linking it to how it improves the new design.
OCR 20228 marksDiscuss the value of product disassembly (reverse engineering) to a designer, and evaluate its limitations and risks.Show worked answer →
A Component 02 levels-of-response question (AO3), marked by levels.
A top-level answer explains the value and weighs the limits. Disassembling a product reveals the materials used, the number and type of components, the construction and assembly methods (snap-fits, screws, adhesives), the tolerances and the design for manufacture and assembly, which a designer cannot tell from the outside. This informs material and process choices, shows how to reduce part count or improve repairability, and benchmarks competitors. The evaluation should weigh the limitations and risks: disassembly is destructive and may not allow reassembly, it shows how but not always why a decision was made, copying a competitor's design raises intellectual-property and ethical issues, and a single example may not be representative. A justified conclusion is that disassembly is highly valuable for understanding construction, materials and assembly, provided it is used to learn and improve rather than to copy, and its findings are checked against other evidence.
Markers reward weighing the value against the limitations and intellectual-property risks with a judgement.
