combining a sleek, customisable design with robust health-tracking features. The minimalist look appeals
to users, while the functionality aligns with fitness and connectivity needs. This balance requires thoughtful
design choices, where aesthetics complement functionality without overshadowing usability, creating
products that users find both attractive and practical
VI. 1. Designers could take inspiration from termite mounds, which maintain stable internal temperatures through
natural ventilation. For a building in a hot, dry climate, the design could incorporate a central cooling system
mimicking the termite mound’s airflow channels. This system would use passive cooling, drawing cool air
from the ground and allowing hot air to escape from vents at the top. Additionally, the building’s exterior
could have reflective, light-colour materials to minimize heat absorption, similar to desert plants. This design
reduces reliance on air conditioning, conserving energy while maintaining a comfortable indoor climate.

2. To redesign a toaster for elderly users, I would focus on ergonomic and safety features. Larger, easy-to-grip
knobs and buttons would reduce strain on the hands, making the toaster more accessible for those with
limited dexterity. I would include a lever that requires minimal force to press down and pops up smoothly
to avoid abrupt movements. Clear, large-print labels and high-contrast colours would enhance visibility for
users with impaired vision. A cool-to-touch exterior and automatic shut-off feature would prevent burns
and ensure safety. These adjustments prioritise functionality and ergonomics.
