Introduction to Design

define a component

smallest identifiable part of a system

define a boundary

something that separates the system from the environment

define engineering design (1)

the process of devising 1). a system 2). component 3). process to meet a desired need/according to a set of specifications

t/f - it is better to base designs off of existing ideas instead of solely relying on your own idea

true

t/f - the main decisive factor in choosing a design option is the client's preferences, values, and priorities

true

define the engineering life cycle (8 steps)

1) needs analysis 2) feasibility study 3) preliminary design 4). detailed design 5). production 6). distribution 7). consumption 8). retirement

list the 4 types of information

1). TECHNICAL 2). stimulation 3). economic 4). acquisition

what should a good purpose statement include?

1). a goal 2). objectives 3). constraints

what are the objectives of evaluating the alternative designs?

1). determining whether alternatives will meet design objectives and constraints 2). estimating production costs 3). failure analysis 4). esthetics (evaluating function and form)

list the fundamental elements of the design process

1). establishment of objective 2). synthesis 3). analysis 4). construction 5). testing 6). evaluation

what does a good project plan include?

1). list of available resources 2). order of tasks to be completed 3). estimates of start/completion dates 4). cost estimations 5). other info relevant to the client

list the 4 characteristics of engineering science problems

1). problem statement is compact and well posed 2). problem has a presumed closure (the solution is presumed to exist) 3). solution is unique and compact 4). problem utilizes specialized knowledge

universal design objectives regardless of the design stage includes...

1). progress updates and project status 2). recording and justifying all changes (written and/or oral)

define the 9 step model of the design process (1-4)

1). recognizing the need (asking questions, don't jump to conclusions) 2). defining the problem (asking more questions, creating purpose statement) 3). planning the project 4). gathering information (how to approach the problem)

define the 9 step model of the design process (5-9)

5). conceptualizing alternative approaches (other ways to approach the problem) 6). evaluating alternatives 7). selecting the best alternative 8).communicating the design 9). implementing the preferred design

what are the objectives of alternative solution conceptualization?

generating a wide range of design options. there is "no such thing as a bad idea" at this stage.

define a subsystem

a collection of components

define a system

a collection of elements that interact to fulfill a function

define engineering design (2)

a decision making process
