Engineering Design Process

Terms in this set (19)

Engineering Design Process
a systematic, iterative problem-solving method that produces solutions to meet human wants and desires.
Science
the study of the natural world; focuses on how and why things happen.
Technology
the study of the designed world; used to solve practical problems and extend human capabilities; developments in technology are evolutionary and are often the result of a series of refinements to an idea or basic invention; focuses on making things happen.
Scientific Method
a linear method for conducting an investigation, which involves making an observation and performing an experiment to test a hypothesis.
Define the Problem
includes developing a problem statement that identifies the what, who, when, and how the problem should be addressed.
Brainstorm Solutions
includes working as a group to develop ideas for possible solutions; record your ideas and employ the rules of brainstorming.
Research Ideas/Explore Possibilities
includes identifying how the problem or a similar problem was addressed in the past and determining what mathematical and/or scientific knowledge is essential to solve the problem.
Specify Constraints and Identify Criteria
includes identifying the criteria and constraints and documenting essential features of the design or how the problem should be solved.
Criteria
guidelines to help develop a solution.
Constraints
limitations of the design when developing a solution.
Consider Alternative Solutions
it is important that designers stay open-minded and necessary for designers to review their ideas against the established criteria and constraints.
Alternative Solutions
several design ideas that could be used to solve a problem.
Select the Approach
determining how to proceed in the Engineering Design Process is based on a schedule or some type of matrix that outlines all ideas based on the criteria and constraints.
Design Proposal
a way to manage simple projects that includes the who, what, when, where, and how to deliver the work, how the solution will be evaluated, and often includes descriptions, sketches, and technical drawings.
Make a Model/Prototype
models and prototypes can be conceptual (abstract models that use language and graphic-based representations to convey meaning), mathematical (abstract models that use the language of mathematics to describe the behavior of the solution) or physical (three-dimensional models, which represent the solution).
Test and Evaluate
this step in the Engineering Design Process is used to evaluate the model/prototype against the given criteria and constraints; all tests should be developed during the design proposal phase.
Refine/Improve
this is an essential step in the Engineering Design Process and is what makes this process unique. The design is constantly reviewed and revised throughout the process so that an ideal solution is developed.
Create/Make Product
building the final product produced, which reflects the design criteria and constraints as well as shows refinement throughout the Engineering Design Process.
Communicate the Results
the Engineering Design Journal and/or an electronic version of the Engineering Design Journal should be kept to record daily interaction with the design problem. This represents your ideas and thoughts throughout the process.
