|
Design is
|
art- create solutions, modifying designs (products and processes are designed)
|
|
|
Analysis is
|
science- study solution options- rigorous, precise, laborious, maybe boring(make sure it works)
|
|
|
What does analysis inform
|
design
|
|
|
What are the stages of design
|
problem, problem definition, brainstorming solutions, prototyping/implementation, testing/evaluation
|
|
|
problem definition
|
the definition will affect the solutions
|
|
|
what are the 3 important terms in brainstorming
|
quantity- more ideas results in better chance of great idea, variety- chance to combine ideas and use diverse groups of people, and don’t criticize-discourages new contributions, evaluate ideas after done generating new ones
|
|
|
experiments inform design process (4 things)
|
observe, hypothesize, predict behavior of design, and experiment
|
|
|
what are the 3 types of experimental variables
|
independent, dependent and control
|
|
|
what is PERIOD analysis
|
P-parameters of interest determined, E-establish the range of parameters, R-repetition of each test, I-increments of each parameter specified, O-order to vary the parameters and D-determine number of measurements needed
|
|
|
how to identify criteria(3 things)
|
clear- which is better, distinguish options, and should be measurable
|
|
|
describe a pairwise comparison
|
chart that compares each option to each other rating which is better for a certain criteria of the project
|
|
|
describe a weighted benefit analysis
|
first column-criterias, second column-the weight of importance for each criteria(ex: 1-10 scale), next columns-options. You then add the scores for each option, then use judgment not just highest score
|
|
|
what does engineering design require(4)
|
knowledge, creativity-we can grow our creativity, people skills/communication, and planning ability
|
|
|
what are 4 main aspects of the not rigid design process
|
synthesis, analysis, communication and implementation
|
|
|
what is synthesis in the design process
|
id problem, constraints and criteria, and search for solutions
|
|
|
what is analysis in the design process
|
search for solutions, analyze them, choose best
|
|
|
what is communication in the design process
|
choose best solution, document it and communicate it
|
|
|
what is implementation in the design process
|
communicate solution and construct it and verify its performance
|
|
|
what is the iterative period in the design process
|
info needed at the beginning is not known until after completing later steps
|
|
|
what is iteration
|
problem solving method with a succession of approximations, each building on the preceding, used to achieve desired degree of accuracy- requires to cycle backwords
|
|
|
what is another name for iteration
|
successive approximation
|
|
|
what are the 4 characteristics of engineering science problems
|
well-posed, unique solution, closure and specialized knowledge
|
|
|
what is needed to be well-posed in engineering science problems
|
complete problem statement, unambiguous and free from internal contradiction
|
|
|
what are the typical answers to a unique solution in engineering science problems
|
a number, set of number or symbolic
|
|
|
what does it mean by closure in engineering science problems
|
easy to recognize when problem has been solved and answer has been obtained
|
|
|
what is specialized knowledge
|
expect homework on circuits not economics when taking circuits
|
|
|
what does open ended mean in design
|
many solutions, some better than others
|
|
|
what does ill-structured mean in design
|
solutions cannot be found following step by step processes
|
|
|
what is a studio aspect to learning design
|
learn by doing, gain experience and developing skills
|
|
|
how should thinking work in design
|
think of all considerations, think parallel rather than serial
|
