Lectures 1-5 Flashcards
What is the Technology readiness level of a product
defines the maturity of the product
What does TRL stand for
technology readiness level
What is the form of a product
The shape of the product
What is the function of a product
The function of the product
What is ergonomics
The design for human use and interface
What is aethetics
Design for beautiful appeal
What is product design a combination of?
Engineering design and industrial design
What does industrial design include
Aesthetics, ergonomic, safety and reliability
How many technology readiness levels are there
9 with TRL0 being the idea and TRL9 being a commercially applicable product
What describes the different stages a product goes through from an idea to a product with a fully commercial application
Technology readiness levels
When a new product uses new technology, what TRLs should it go through
all of them
When a product uses existing technology, which TRLs should it go through
From TRL4 (small scale prototype)
Does a product have to sequentially go through the TRL levels
No, level 2 may start before level 1
What TRL levels do universities deal with
TRL 0-4
What TRL levels do industry tend to deal with
TRL 2-9
Why is it important for products to go through systematic methods and procedures?
So that decisions can be made efficiently and effectively
How many parts may a car contain
10,000 parts
Why is a product so complex
because a product has thousands of parts and each part involves a lot of precise design information. Also each part may also represent a complex technology itself
Give an example of a known unknown
true safety margins (some safety margins may be less than thought)
Give an example of an unknown unknown
load cases that cannot be predicted
Explain the complexity of organisations that may occur when producing a car
Designing a car involves multiple companies with diverse multi-disciplinary design teams consisting of thousands of people. A car may contain parts from 100s of different suppliers in a hierarchical structure
Why must each part have a paper trail
so that it can be shown where a part has come from and that the original supplier has quality control methods and has carried out necessary test verification. This is to help give proof if a company is prosecuted for false claims
Describe the complexity of documentation
The fact that commercial products need verification and documentation
What are the 8 major objectives of a car
Technical performance Cost Environment Ergonomics Aesthetics Reliability and Safety Manufacturing
