Industrial Design Vocabulary Quiz
12 multiple-choice questions on industrial and product design vocabulary: prototype, ergonomics, CAD, mock-up, usability, iteration, design brief, rendering, injection moulding, user testing, form factor and manufacturing tolerance. B2–C1 level.
This quiz focuses on how the target vocabulary for Industrial Design is actually used in context at B2–C1 level, rather than testing bare definitions. Correct answers you will need to identify include terms such as prototype, ergonomics, Computer-Aided Design, mock-up and iteration, each embedded in a full example sentence so you have to judge meaning from context, not just recognise an isolated word.
Working through all 12 questions and checking the explanations in the FAQ below is a quick way to spot any terms you are still unsure of. Revisiting the quiz again after a day or two, rather than only once, is one of the most reliable ways to move new vocabulary from passive recognition into words you can use confidently yourself in speaking and writing.

Industrial Design Vocabulary — FAQ
What is a prototype in industrial design?
A prototype is an early model or sample of a product built to test a design concept before full production. Prototypes range from simple foam or cardboard mock-ups to fully functional models. They allow designers and engineers to evaluate shape, ergonomics, materials and usability before committing to expensive manufacturing tooling. The word comes from Greek 'prototypon', meaning 'first impression'.
What is ergonomics and why does it matter in product design?
Ergonomics (also called human factors engineering) is the science of designing products, systems and environments to match the physical and cognitive capabilities of the people who use them. Good ergonomic design reduces fatigue, injury and error while improving comfort and productivity. In product design, ergonomic principles influence the shape of handles, the height of controls, the legibility of displays and the weight distribution of handheld devices.
What does CAD mean and how is it used in design?
CAD stands for Computer-Aided Design. It refers to software tools — such as SolidWorks, Rhino, AutoCAD or Fusion 360 — that allow designers and engineers to create precise 2D technical drawings and 3D digital models of products. CAD files can be used to generate renderings, run simulations, produce technical documentation and send geometry directly to CNC machines or 3D printers for prototyping and manufacture.
What is the difference between a mock-up and a prototype?
A mock-up is typically a rough, non-functional visual or physical representation of a product used to explore form, proportions and aesthetics early in the design process. It is usually quick and cheap to make. A prototype, by contrast, is a more developed model — often functional — used to test specific aspects of performance, usability or manufacturing. Both are tools for communication and testing, but prototypes are typically more refined and closer to the final product.
What does 'design brief' mean in a project context?
A design brief is a document that defines the scope, goals, constraints and requirements of a design project before work begins. It typically includes the problem to be solved, the target user, the budget, timeline, technical constraints and any aesthetic or regulatory requirements. A well-written design brief aligns the designer and the client from the start, preventing misunderstandings and guiding all subsequent design decisions.
What is iteration in the design process?
Iteration is the practice of repeatedly refining a design through cycles of making, testing and improving. Rather than trying to get the design perfect in one attempt, designers build a version, test it against user needs or technical requirements, learn from the results and then improve the design in the next cycle. This iterative approach is central to user-centred design methodologies such as Design Thinking and Agile product development.
What is a rendering in industrial design?
A rendering in industrial design is a realistic visual representation of a proposed product, showing its appearance in terms of colour, material, surface finish, lighting and shadow. Renderings can be produced digitally using software such as KeyShot or Blender, or drawn by hand using markers and coloured pencils. They are used to communicate design concepts to clients, stakeholders and marketing teams before a physical prototype is built.
What is injection moulding and what products use it?
Injection moulding is a high-volume manufacturing process in which molten thermoplastic material is injected under pressure into a steel or aluminium mould. When the material cools and solidifies, the mould opens and the finished part is ejected. It is one of the most common methods for producing plastic consumer products, including bottle caps, electronic housings, toys, automotive components and medical devices. Tooling costs are high but the process is highly repeatable and cost-effective at scale.
What is user testing and when does it happen?
User testing (also called usability testing) is a research method in which real representative users interact with a product — or a prototype of it — while designers observe and record their behaviour. It typically happens at multiple stages: early in the process with low-fidelity prototypes to test concepts, and later with high-fidelity prototypes or finished products to catch usability issues before or after launch. The insights gathered directly inform redesign decisions.
What is manufacturing tolerance and why is it important?
Manufacturing tolerance is the permissible range of variation in a product's dimensions or properties during production. For example, a hole specified as 10 mm diameter with a tolerance of ±0.1 mm means any hole between 9.9 mm and 10.1 mm is acceptable. Tolerances are critical because no manufacturing process is perfectly repeatable: tight tolerances ensure parts fit and function correctly but increase cost, while looser tolerances are cheaper but may affect quality or assembly.
