A2 design challenges

Question 1

product life cycle

Answer 1

design
raw material extraction - recycling
raw material processing
manufacturing
packaging
distribution
use/ reuse - maintenance
end of life
landfill or recycled

Question 2

cost reduction over the product life cycle

Answer 2

using the expensive design and compensating for the money by recycling at the end of the product life cycle

Question 3

sustainability

Answer 3

manufactures have to oblige to legal and moral responsibilities. with pressure from governments groups of people and companies have to satisfy the needs of other people to remain in business.
car manufacturers reuse old car parts.

Question 4

reduction of energy during the design

Answer 4

3D CAD modeling
computer simulations
rapid prototyping
online collaboration 
virtual design environments

Question 5

reduction of energy during operation

Answer 5

increasing system efficiency
increasing component efficiency
reducing product mass
reducing product dimensions

Question 6

energy recovery features

Answer 6

hybrid cars use the heat energy from the brakes to turn it into electricity which can power the car

Question 7

reduced product lifecycle costs

Answer 7

allowing for products to be dismantled allows for lower recycling costs

Question 8

integration of different power sources for vehicles

Answer 8

hybrids use electricity and gas to run their engines

Question 9

designing out the risk for employees

Answer 9

providing the proper training for the empolyees

Question 10

reduction of physical mass

Answer 10

heavier objects need more energy to mass

so F1 cars use carbon fibre because it’s light so acceleration is maximised

Question 11

reducing product dimensions

Answer 11

using smaller components. surface mount technology

Question 12

increasing system efficiency

Answer 12

using compatible components and subsystems to minimize overall energy consumption. such as hybrid cars

Question 13

increase in product efficiency

Answer 13

using more efficient components such as LEDs
