IB Design Technology Topic A3.4.2 Responsible Use of Electronics Revision Notes (HL) | RevisionDojo

Written by official IB examiners

Electronics Are Everywhere, So the Design Choices Matter

Electronics are now in almost every product, so a small design decision gets multiplied by millions of units.
A responsibly designed electronic product has to satisfy three demands at once:
1. Safe: it must not harm the user or the environment.
2. Energy efficient: it must do its job for the least energy possible.
3. Sustainable: it must last, and be repairable and recyclable at the end of its life.

Note

These three often pull against each other.
A sealed, glued case is safer and more waterproof, but it is also impossible to repair, so it fails on sustainability.
Responsible design is the management of that tension, not a checklist.

Safe

Protecting the user: shielding, insulation and proper ventilation keep voltage and heat away from hands.
Fail-safes: warnings, automatic shutdown and circuit breakers make the product safe when it goes wrong, not just when it works.
Environmental safety: avoiding toxic materials such as lead and mercury, which leach out of landfill and into ecosystems.

Energy Efficient
