Question 1

How do I evaluate the social impact of a new technology in my design?

Accepted Answer

Start by identifying who is affected: users, workers, communities, and society at large. For example, if you're designing a smart home system, consider privacy (data collection), convenience (automation), and potential job loss for security guards. Use a table to list positive and negative impacts, then weigh them against each other. In your evaluation, explain how your design decisions mitigate negative impacts—like adding user control over data sharing.

Question 2

What is the difference between ethical and moral implications in design?

Accepted Answer

Ethical implications refer to professional codes of conduct and societal norms—like ensuring a product is safe and not deceptive. Moral implications are more personal, based on individual beliefs about right and wrong. For example, using child labour is both unethical (violates labour laws) and immoral (most people believe it's wrong). In exams, you can use the terms interchangeably, but it's good to show you understand the nuance.

Question 3

How do I apply lifecycle assessment to a technology like 3D printing?

Accepted Answer

Break it into stages: raw materials (plastic filament from oil or recycled sources), manufacturing (energy for printing, waste from supports), distribution (shipping digital files vs. physical goods), use (energy consumption, durability), and disposal (can it be recycled?). Compare with traditional manufacturing: 3D printing uses less material but may use more energy per part. Your evaluation should conclude whether the technology is more sustainable overall for a specific application.

Question 4

Can you give an example of a cultural impact of a new technology?

Accepted Answer

Sure. Consider the use of AI in music composition. It can create new genres and preserve traditional music by analysing patterns, but it might also homogenise music if algorithms favour popular styles. A designer creating a music app might decide to include features that promote diverse cultural expressions, like a 'world music' filter. In your evaluation, discuss how technology can both celebrate and threaten cultural diversity.

Question 5

What economic factors should I consider when evaluating a new material?

Accepted Answer

Key factors include: cost of raw materials (e.g., rare earth metals vs. abundant ones), manufacturing costs (energy, labour, tooling), market demand (will consumers pay more for sustainable materials?), and long-term savings (e.g., lower maintenance). Also consider economic impact on local communities—e.g., using a locally sourced material supports local jobs but might be more expensive. Always link back to your design decisions: if the material is too costly, you might use it only for key components.

Question 6

How do I structure an exam answer on critical evaluation of technology?

Accepted Answer

Use a clear structure: 1) State the technology and its purpose. 2) Describe one impact (e.g., environmental) with specific evidence. 3) Explain how this impact informs a design decision (e.g., choosing a biodegradable material). 4) Repeat for a second impact (e.g., social). 5) Conclude by weighing the trade-offs and justifying your final design choice. Use connectives like 'however', 'on the other hand', and 'therefore' to show critical thinking.
