PLTW The Design Process Steps
Terms in this set (42)
Repeating a process to yield results successively closer to the goal.
A method of shared problem solving in which all members of a group spontaneously, and in an unrestrained discussion, generate ideas.
A tool for systematically ranking alternative solutions according to a set of criteria. This is the step for brainstorming and exploring alternative ideas based on further knowledge and technologies.
An iterative decision-making process that produces plans by which resources are converted into products or systems that meet human needs and wants or solve problems.
A written plan that identifies a problem to be solved, its criteria, and its constraints. The design brief is used to encourage thinking of all aspects of a problem before attempting a solution.
A systematic problem-solving strategy used by engineers, with criteria and constraints, used to develop many possible solutions to a problem or to satisfy human needs and wants and winnow (narrow) down the possible solutions to one final choice.
A person who designs any of a variety of things.
A person who is trained in and uses technological and scientific knowledge to solve practical problems.
To form an idea of the amount or value of; assess.
A visual, mathematical, or three-dimensional representation in detail of an object or design, often smaller than the original. A model is often used to test ideas, make changes to a design, and to learn more about what would happen to a similar, real object.
The process of understanding a problem, devising a plan, carrying out the plan, and evaluating the plan in order to solve a problem or meet a need or want.
Human activities used to create, invent, design, transform, produce, control, maintain, and use products or systems; a sequence of actions that combines resources to produce an output.
A full-scale working model used to test a design concept by making actual observations and necessary adjustments.
Systematic, scientific, documented study.
A method for collecting data.
Define the Problem
Step 1 of the Design Process- Using a Design Brief, the problem is presented with criteria needed to be fulfilled in the solution.
Step 2 of the Design Process- Gathering of ideas and narrowing it down using a decision matrix to determine the best design for the solution.
Research and Brainstorming
Needed to Generate Concepts
Develop a Solution
Step 3 of the Design Process- Use of technical drawings to begin seeing the entire picture of the solution. Develop detailed and annotated sketches of design.
Completed in Step 3 of the Design Process. Develop detailed and annotated sketches of design.
Step 5 of the Design Process- Test, prove that the solution solves the problem presented in Defining the Problem (step 1)
What individuals do together to solve a problem that is presented in Define the Problem (step 1)
Construct and Test Prototype
Step 4 of the Design Process- Make a 3D model of the solution (prototype). Fabricate a functional prototype and test under controlled conditions, record results and evaluate it's effectiveness.
Step 6 of the Design Process- presentation of solution to the people who offered the Design Brief (problem)
Used to document the project and given to the people who offered the Design Brief (problem)
Used to communicate the project to the people who offered the Design Brief (problem)
A sketch in which an object's parallel edges are drawn with parallel lines, typically at 30-degree angles to the horizontal baseline. There are no vanishing points and three sides of the object can be seen simultaneously.
A sketch typically including three primary views of an object that are drawn using orthographic projections. The top, front, and right primary views of the object are projected onto a drawing plane perpendicular to each view. An isometric sketch of the object is often included.
The process of working together in a common process.
Rules or requirements that a design must follow.
A limit or restriction to a design process. Constraints may be such things as appearance, funding, space, materials, and human capabilities.
Measurement in length, width, and depth.
cerebral palsy (CP)
A condition that affects body movement and coordination. It is caused by brain injury or brain malformation that occurs before, during, or immediately after birth when an infant's brain is still developing.
Observing (documenting) the operation of a device and describing its function and design specifications.
A change or improvement designed to produce optimal accuracy and function.
A type of pictorial drawing in which vanishing points are used to provide the depth and distortion that is seen with the human eye.
A preliminary visual of a possible idea for a design. Most thumbnail sketches are not full size and have little detail. Their purpose is to help quickly explore possible alternative designs.
A statement that briefly describes the design goals and needs of stakeholders.
A clear and concise identification and description of the design problem or opportunity.
A solid modeling design method where parts of a whole geometric primitive are removed to create a new object.
Having the dimensions of height, width, and depth.
