Q

What is continuous improvement? (kaizen)

A
  • It is an approach that seeks to be continually improved and develop product services and procedures for the better.
21
Q

Efficient working aims to remove waste from any process which may manifest itself as:

A
  • wasted time
  • overproduction
  • wasted resources including power
    -wasted activity
22
Q

What is pollution?

A

the release of contaminating substances that are likely to harm the natural environment

23
Q

How does the pollution of our rivers, seas and waterways affect us?

A

Water pollution also poses a direct threat to wildlife. Many pollutants are toxic to aquatic life, causing disease and death among fish and other species.

24
Q

What is global warming?

A
  • primarily caused by an excess of CO2 in the atmosphere that traps heat warming the earth.
  • the burning of fossil fuels increases the amount of CO2 therefore increases the amount of heat.
25
Q

How dangerous is battery production ?

A
  • battery production uses finite and dangerous metals.
  • the production process is very intensive
  • proper disposal of batteries is required to prevent leaching alkalis into the environment. which could damage wildlife.
26
Q

what’s the alternative to battery power?

A

rechargeable batteries

27
Q

Why is research and development so important in companies?

A

those companies who are first to the market with a new product can often have a key advantage over their competitors.

28
Q

What is a technology push?

A

new technology is often pushed onto the market driven by research.
Often consumers are not aware of the new technology and the advantages it brings.

29
Q

What is a market pull?

A

consumer driven pressure causes manufactures to continuously develop new products or add functionality to existing products.

30
Q

Case Study: spider silk

A
  • Spider silk has greater tensile strength than steel yet it is lightweight with high elasticity.
  • synthetic spider silk could be the biggest technological advancement since nylon
31
Q

What are Cobots?

A

they are collaborative robots or “cobots” are being developed to allow greater human-robot interaction. Robots will work with humans rather than for them. they can significantly improve productivity.

32
Q

what is inclusive design?

A
  • design may be developed to be easily used by the elderly or disabled.
33
Q

what are the benefits of automation?

A
  • increased efficiency and productivity
  • robots can replace manual jobs therefore saving labour costs.
34
Q

What is Computer Aided Design (CAD)?

A

CAD software is used to create precise 2D or 3D drawings/models.

35
Q

Advantages of CAD?

A
  • CAD is very accurate
  • designs can be worked on by remote teams simultaneously
  • Designs can be created, saved and edited easily, saving time
36
Q

Disadvantages of CAD?

A
  • CAD is complex to learn
  • software can be very expensive
  • security issues - risk of losing data
37
Q

What is Computer Aided Manufacture (CAM)?

A
  • automated machinery is controlled by software to manufacture physical parts.
  • CAM uses computer numerical control (CNC) and CAD files to create a design for the machinery to follow.
38
Q

CNC Miling?

A

CNC mining machines work in three dimensions to produce intricately and accurately machined objects.

39
Q

What is CNC laser cutting?

A

is a computer-controlled cutting machine that uses a high-powered laser beam to cut through materials such as metal, wood, and plastic.

40
Q

what is flexible manufacturing systems (FMS)

A

FMS involve an assembly of automated machines commonly used on short-run batch production lined where the products frequently change.

41
Q

What is Lean Manufacturing?

A

Lean manufacturing is a Japanese concept, based on minimising costs and maximising efficiency by cutting down on waste and the amount of materials and energy used in production.

42
Q

What is Just In Time (JIT) production?

A
  • items are created as they are demanded. No surplus stock of raw materials, components or finished parts are kept.
43
Q

Advantages of JIT?

A
  • no warehousing costs
    -stock doesn’t become damaged
  • reduces waste
44
Q

Disadvantages of JIT?

A
  • more planning is required
    -risk of production delays
    -reliant on your supply chain
45
Q

the success of new technologies are frequently evaluated according to these following points?

A
  • cost
    -reliability
    -longevity
    -sustainablity
    -recyclability
46
Q

if you are designing a new product, you will need to gather opinion and facts about?

A
  • available technology
  • size of market
  • the market need
  • successes and failures of other products
47
Q

what is planned obsolescence?

A

Planned obsolescence describes the practice of designing products to break quickly or become obsolete in the short to mid-term.

48
Q
A
