What can you learn by taking apart and critiquing products that already exist?

Analysing existing products through product analysis and disassembly: examining materials, components, manufacture, function, ergonomics, aesthetics, cost and environmental impact to learn from them and inform new designs.

What this dot point is asking

OCR J310 expects designers to learn from existing products and practice. The main tool is product analysis, often involving disassembly (taking a product apart). By examining how a product is made, what it is made from, how well it works and what it costs, a designer gathers real evidence to inform a new design and to write a justified specification. In the written exam this appears as questions on what disassembly reveals and how analysing rivals helps a new design.

What product analysis is

A designer rarely starts from nothing. Studying products that already address a similar need is faster and more reliable than guessing, and it grounds the new specification in evidence.

What to analyse

A useful memory aid for this is ACCESS FM (Aesthetics, Cost, Customer, Environment, Size, Safety, Function, Materials), a checklist that prompts you to consider each angle in turn.

What disassembly reveals

Taking a product apart shows what looking at the outside cannot:

  • The materials used inside and how many different ones (fewer, similar materials are easier to recycle).
  • The fixings and joints (screws, snap-fits, adhesives, welds), which hint at how it was made and whether it can be repaired.
  • Evidence of the manufacturing method (moulding marks, machined surfaces, standard components).
  • Where the product might fail or could be simplified.

Turning analysis into a better design

Analysis is only useful if it feeds the new design. From a product analysis you can:

  • Keep what works (a feature users value, a sensible material choice).
  • Fix what fails (a part that breaks, a control that is awkward).
  • Set realistic targets for cost, quality and performance, based on what rivals achieve.
  • Find a gap to make your design better (more sustainable, easier to use, cheaper).

Try this

Q1. State two things a designer can learn by disassembling a product. [2 marks]

  • Cue. Any two of materials used, how parts are joined, how it was manufactured, where it might fail.

Q2. Give one letter of ACCESS FM and state what it prompts you to consider. [2 marks]

  • Cue. For example F = Function (does it do its job well?), or M = Materials (what is it made from and why?).

OCR J310/01 20183 marksDescribe what a designer can learn by disassembling an existing product.
Show worked answer →

A 3-mark Describe wants three things learned from taking a product apart.

Materials and components: which materials and parts are used and why (for example a tough polymer casing, standard screws). Construction and manufacture: how the parts are joined and how the product is likely to have been made (snap-fits, moulded parts, fixings), which shows the scale of production. Function and improvement: how the parts work together, where it could fail, and how it could be made cheaper, safer or easier to repair.

Markers reward three distinct points (materials, construction/manufacture, function or how it could be improved). Repeating one idea in different words caps the mark.

OCR J310/01 20226 marksA student is designing a new reusable coffee cup. Explain how analysing existing coffee cups would help them develop a better design.
Show worked answer →

A 6-mark Explain wants product analysis applied to the coffee cup.

Analysing materials shows what works (an insulating wall to keep drinks hot, a food-safe lid) and what to avoid, so the student can choose better materials. Analysing function and ergonomics reveals problems users complain about (lids that leak, cups too hot to hold, hard to clean), giving clear targets to improve. Analysing manufacture and cost shows how rivals keep the price down, helping the student set a realistic cost. Analysing environmental impact (is it recyclable, how long does it last?) suggests sustainability improvements that differentiate the new design.

Markers reward several developed points, each naming what is analysed and how it informs the new cup. A general "to get ideas" answer with no specifics caps the mark.
