Lecture 7 - Design and Economics Flashcards
What is design?
A plan or drawing to show the look, function and/or workings of a building, system, or other object before it is made
What are key points about the design centre Bauhaus?
1) Translates to ‘school of building’; was founded six months after the end of WW1
2) Operational from 1919-1933 until it was closd by Nazi pressure; deemed a centre of communist intellectualism
What workshop did Marcel Breuer run from 1924-1928?
Cabinetmaking workshop
What are key points about the design centre Skunkworks Projects?
1) More aviation focused
2) ‘Skunk Works’ is a pseudonym for Lockheed Martin’s Advanced Development Programs; created in June 1943
3) Philosophy for rapid innovation
What is the term ‘skunkworks’ generally used to describe?
This term is used to describe an elite group within an organization which has:
1) A hugh degree of autonomy
2) Unhampered by bureaucracy
3) Main task of working on advanced/secret projects with a goal of innovation
What are steps (in order) which make the design process?
1) Research
2) Design Requirements
3) Feasability
4) Conceptualization
5) Preliminary Design
6) Detailed Design
7) Integration and Testing
8) Production Planning
What are key points of the step ‘research’?
1) Significant amount of time allotted to locating information
2) Consideration should be given to existing applicable literature, anything that has already been patented/intellectual property
3) Mindful of the sources being used
What are key points of the step ‘design requirements’?
1) One of the most important part of the design process; predicts the fate of a project
2) Putting in requirements and their analysis
3) This step essentially guides the design through the rest of the process
4) Framework of the design project
5) Compared to the requirements at the end to ensure it meets expected functionality
What are the two sets of design requirements?
1) Requirements given by the customer; general overview of required functionality
2) Internal requirements; where the compay created a set of internal/more specific requirements for the design
What are the 3 types of statements in a requirements document?
1) Shall (Requirement) - Must be implemented (and must be testable)
2) Will (Fact) -Will state a fact or declaration of purpose for the design
3) Should (Goal) - Non-mandatory, typically defines something to maximize or minimize
What are key points of the step ‘feasability’?
1) Evaluate the design idea by performing a feasability study and analysing the designs potential to determine whether the project can proceed into the design phase
2) Studies based on two main criterias: is the project achievable, is the project within cost constraints
What are key points of the step ‘conceptual design’?
1) Concept studies are often a phase of project planning that includes producing ideas and considering the pros and cons of inplementing those ideas
2) Done to minimize likelihood of error, manage costs, etc
3) Weighted trade studies = concrete method of evaluation
What are key points of the step ‘preliminary design’?
1) Overall system and it’s conceptualization plans may provide early project configuration
2) System may be broken into subsystems responsible for various tasks
3) Focuses on creating a baseline for the project to be built upon
What are key points of the step ‘detailed design’?
1) Further elaborates each aspect of the project by complete description
2) Making sure every specification is measured out (a complete product on paper)
3) CAD programs
What are key points of the step ‘verification and validation testing’?
1) Another round of evaluations
2) Verification = Meets the design specifications
3) Validation = meets the operational needs of the user
