100% Correct Exam Answers- 2025/2026
Updated
What is the difference between a prototype and a final product in design technology?
A prototype is a preliminary model used to test and evaluate concepts, while a final product is the
completed, market-ready version.
How does ergonomics impact the design process?
Ergonomics ensures that a product is comfortable, efficient, and safe for human use, improving both
functionality and user satisfaction.
What is the role of sustainability in product design?
Sustainability involves designing products that minimize environmental impact through
energyefficient materials, recycling, and waste reduction.
How do anthropometrics influence design decisions?
Anthropometrics involves studying human body measurements to design products that fit
comfortably and safely for the intended user group.
What are the main considerations when choosing materials for a design?
Considerations include the material’s strength, durability, cost, availability, environmental impact, and
suitability for the product’s purpose.
Why is it important to consider aesthetics in design?
Aesthetics enhance the visual appeal of a product, which can influence consumer desire, brand
image, and market success.
What is the role of CAD software in modern design technology?
1
, CAD software allows designers to create precise and editable digital models, facilitating testing,
modifications, and communication of designs.
How do environmental factors affect design technology?
Environmental factors, like climate, geography, and resource availability, influence material choice,
energy efficiency, and overall sustainability of a design.
What are the key components of the iterative design process?
The iterative design process includes prototyping, testing, evaluating, and refining a design based on
feedback and performance.
How does user feedback contribute to product development?
User feedback helps designers understand real-world functionality, preferences, and pain points,
leading to improvements and refinements.
What is the importance of the manufacturing process in design?
The manufacturing process determines the efficiency, cost, and quality of production, influencing the
final product's market competitiveness.
How can a designer ensure that a product is cost-effective without compromising quality?
By optimizing material use, selecting efficient manufacturing methods, and focusing on minimal
waste, designers can balance cost and quality.
What are the differences between qualitative and quantitative testing in design?
Qualitative testing focuses on user experiences and feedback, while quantitative testing gathers
measurable data to evaluate performance and efficiency.
Why is prototyping essential in the design process?
Prototyping allows designers to test ideas, identify potential issues, and make adjustments before
producing the final product.
