Q

With analysing questions, how many points should you make?

A

As many as you can, try to get an even ammount of pros and cons - but doesnt matter - have to justifty each point to secure full marks

Q

What is the best way to answer the analysis question?

A

To round up all your points using specification and somtimes the image provided and make sure you can justify each one and then writing as many as you can in rougly a mark per min so 8 mins 2 mins planning 6 mins writing

Q

What is a systems approach?

A

When a systematic approach is taken as a stratagie - this can include using bar charts, flow charts, pi charts, surveys, graphs etc + logical approach is particularly useful in electronics where there is an input, process and output close input,

Q

What is iterative design?

A

A continual cycle of improving a design -
* Research
* Design
* Test
* Analyse
* Research
* Design …..

20
Q

What is design fixation?

A

When a designer becomes focused on a single idea/ has tunnel vision - when a designer can only think of one specific idea which narrows down variation/ creativity

21
Q

What are some of the most common methods to generating designs?

A
  • Sketching
  • Mindmaps
  • Prototyping
  • 3D CAD drawings
  • Testing
22
Q

What are the benefits of prototyping ideas?

A

Can help to understand -
* how to manufacture it/ possible materials
* how it functions
* scale and physical interaction
* aesthetics

23
Q

What are the 3 different types of testing?

A
  • Destructive testing
  • Non-destructive testing
  • Market testing
24
Q

What is destructive testing?

A

Testing used to determine how a product would respond under extreeme conditions - help designer produce the safest product e.g. a car to make sure all passengers would be safe if in a car crash

25
Q

What is non-destructive testing?

A

Testing that evaluates a product for any defects/ flaws without causing any damage - designers can sometimes use x-rays to examine any flaws

26
Q

What is market testing?

A

When a product is given to a foucs group or client to see how in preforms in use - normally done once the product has been deemed safe

27
Q

List 2 reasons why accuracy is important when making products?

A
  • To ensure all mechanisms fuction as intended by manufacturer
  • To ensure product is the correct scale/ size for consumer
28
Q

What does tolerence mean?

A

Tolerence is the ammount in which a measurement can vary without affecting a function or the manufacture

29
Q

What does it mean if a product has a high tolerence?

A

That it doesnt have to be exact - large area for not precise measurements

30
Q

What does if mean if a product has a low tolerence?

A

That it has to be extremely precise

31
Q

List 3 ways to maintain accuracy when prototyping

A
  • Measuring and quality control continuously/ comparing to technical drawing
  • Using a productin aid e.g. jig or template to ensure speed and also high accuracy
  • If using CAD checking digital measurements/ units
32
Q

What is tesselation?

A

The efficient interlocking of shapes (that match) to minimise waste

33
Q

What is nesting?

A

Nesting is cleverly arranging different shapes together to reduce waste

34
Q

What does wastage mean?

A

The process of removal of mateiral using tools and equipment - ideally good designers try to minimise ammount of waste produced e.g. nesting/ tesselation

35
Q

What is kerf?

A

The width of the blade that you are using - needs to be taken into account when marking out/ cutting especiallty if a product has a low tolerence (because if its e.g. 0.5mm thick that could take up/ cut away material that was required/ in the tolerence)

36
Q

Why does the kerf of a saw/ laser need to ben taken into consdideration?

A

Because it can take away material e.g. if a design was tesselated and then cut with a 3mm saw, it would take off material so you have to take kerf into consideration anf, for example, leave a 3mm gap when tesselating

37
Q

What is a dautum point?

A

A surface/ edge used as a reference from which measurements are taken to improve accuracy

38
Q

What is a ferrous material?

A

One that contains iron

39
Q

What is kevlar?

A

Kevlar is a type of aramid fiber. It is woven into textile materials and is extremely strong and lightweight, with resistance toward corrosion and heat. It is used in vast applications such as aerospace engineering (such as the body of the aircraft), body armor, bulletproof vests, car brakes, and boats.

40
Q

What is a commercial process for timber?

A

routing or turning

41
Q

What is a modern material?

A

Developments made through the invention of new or
improved processes

42
Q

Give an example of a modern matieral

A

Graphene is a single carbon layer material which is hypothetically 100 times stronger than steel. It is hypothetical because we are yet to manufacture it in large enough quantities to prove this. In theory, it could provide body armour that is bulletproof, invisible and almost weightless.

43
Q

What is Process time?

A

The processing time is the time required to process a work item. It is the time spent on manufacturing a product or providing a service

44
Q

Name a product assosciated with fairtrade

A
  • bannas
  • cotton
45
Q

What is the need of fairtrade?

A
  • improves pay for farmers in developing countries
  • improves access to education for families
  • gives small scale farmers access to large global scale markets
  • ensures workers get a fair price for their work
46
Q

Give an example for people whom benifit from fairtrade

A

Farmers/ families of farmers who recieve help via ensuring good pay and providing eduacation for their children e.g. communities that get help setting up local ammenities such as schools/ shops/ wells etc
