Intro Flashcards
Product liability
• Legal obligation of the company/manufacturer to account for health and safety risks of the product
- not the resellers responsibility
- does not only apply to defective products
Why does the cost of a defect to the company increase further along the production process?
• product liability
- refers to the legal responsibility of manufacturers, distributors and sellers for injuries or damages caused by defective products
•future issues
- should the faulty component be part of a larger system, the cumulative damage can become very expensive to repair
•logistics of recalls
- if recalls are necessary, it can be very costly to do a full product recall, transporting, storing, fixing and redistributing the defective goods can be expensive
• Opportunity cost
- valuable resources are being spent going backwards to fix things instead of progressing and growing
What is online monitoring? And some of its benefits
It is part of the 4th Industrial Revolution. It can detect faulty parts while the part is still on the production line, and halt production, preventing that defect from moving further thus saving future costs. Can benefit process quality control.
Name the two cycles involved in Green Manufacturing and briefly describe them.
Biological cycle: biodegradable (how the component decomposes in the ground). A component has a biological cycle if it is BIODEGRADABLE.
Industrial cycle: the process in which a component is RECYCLED
Give some design considerations regarding Design for Disassembly (DFD)
• ease of disassembly at the end of the product life cycle
• a focus on tear down for recycling
Give some examples of poor DFD
Milk cartons have aluminum foil on the interior which is difficult to separate from the cardboard - making recycling more difficult.
Coke bottles and their lids are made of two different types of plastic, and therefore can’t be recycled together making the process more tricky.
Computer chips and components are difficult to remove and disassemble from the motherboard.
Give some examples of good DFD
Desks or tables are designed to be assembled and disassembled by making use of rivets, fasteners, screws and bolts instead of using things like glue or welding components together permanently.
Give some design considerations regarding Design for Service
• easy access to components that you expect will need to be replaced
• show consideration for maintenance
Regarding a faulty camera and a smart phone, and being able to replace the camera instead of the entire smart phone.
What action would play into DFD and what action would play into DFS?
DFD: being able to remove the camera from the smart phone
DFS: replacing the camera without replacing the smart phone.
Implications of alloying in DFD & DFS
• the fact that metal is an alloy instead of pure metal in the case of popular alloys like AL2024 does not affect recyclability
• unless used in galvanising (protective playing against corrosion), there will not be a pure metal used in engineering application
• most alloys have a small alloy percentage
• If separation is necessary, it’ll be done by a chemical process
Name a concern with alloying and give an example
From a design for recyclability (DFR) perspective, pollutants are the main concern with alloys.
An example is chromium, which is a known environmental pollutant that can be found in stainless steel.
