Design Process : Present ideas in group. Generate and record ideas. Seek quantity not quality. Keep the mind alert through rapidly paced sessions. Show Answer
Design Process Answer: Brainstorm Back to Board
Design Process Question for 10 points Initiate further development of brainstorming ideas with constraints and tradeoffs considered. Explore alternative ideas based on further knowledge and technologies Show Answer
Design Process Answer for 10 Points Explore Possibilities Back to Board
Design Process Question for 15 Points Identify a problem that exists. Determine the root cause. Gather information. Show Answer
Design Process Answer for 15 Points Define a Problem Back to Board
Design Process Question for 20 Points Reassess the validity of the design criteria and make adjustments to the design brief, if necessary. Work through the design process until the solution satisfies the design criteria. Update the documentation of the final solution. Show Answer
Design Process Answer for 20 Points Refine the Design Back to Board
Design Process Question for 25 Points Present oral presentations with visual aids (computer generated slide show, models, prototype). Develop written reports with appropriate graphic documentation (charts, graphs, technical drawings, renderings, etc.). Market the Product. Distribute. Show Answer
Design Process Answer for 25 Points Communicate Processes and Results Back to Board
Give Four examples of Geometric Constraints Show Answer
Constraints (Perpendicular, Parallel, Tangent, Coincident, Concentric, Collinear, Horizontal, Vertical, Equal, Fix, Symmetric) Back to Board
What is a parametric constraint? Show Answer
Parametric Constraints (Used to control the size and location of geometry. May Take the form of abstract algebraic formulas such as d1=(d2*d0)/d5.) Back to Board
What is an Assembly constraint? Show Answer
A parameter that defines the geometric relationships between components in a CAD assembly. Back to Board
Name three assembly constraints. Show Answer
Mate, flush, angle, tangent, insert… Back to Board
What are the 6-degrees of freedom? Show Answer
Degrees of Freedom:A component floating in space has six degrees of freedom:3 rotations around the X, Y, and Z axes.3 lineartranslations along the X, Y, and Z axes. Back to Board
Name the three main types of 3-D pictoral sketching Show Answer
Isometric Oblique and Perspective Back to Board
What is an isometric sketch? Show Answer
Isometric – angle to the horizon is 30° for both depth and width, 90° for height; all axis drawn to the same scale. Back to Board
What is a perspective drawing? Show Answer
Perspective – Lines converge on a ‘vanishing point’ (VP) off in the distance. Subdivided into additional types: 1 point has one VP on the horizon, 2 point perspective has two VPs on the horizon and 3 point perspective has three VPs, two on the horizon and one either above or below. Back to Board
What is an oblique drawing? Show Answer
Oblique – width is show horizontal, depth goes back at an angle, typically 30°, 45° or 60°. Back to Board
What is the difference between cavalier and cabinet drawings? Show Answer
Cabinet is half depth cavalier is full depth Back to Board
What is reverse engineering? Show Answer
The process of taking a product apart to determine function Back to Board
What are the three types of analysis involved in reverse engineering? Show Answer
Visual Functional Structural Back to Board
What are the six elements of visual design? Show Answer
Line Color Form/Shape Space Texture Value Back to Board
What are the five principles of design? Show Answer
Balance Rhythm Emphasis Proportion and scale Unity Back to Board
What is difference between structural and functional analysis? Show Answer
Functional Analysis (the product’s purpose is identified; determine how the product functions; the system’s inputs and outputs are listed) Structural Analysis (materials used; fastening methods) Back to Board
What is a Gantt Chart? Show Answer
(A time and activity bar chart that is used for planning, managing, and controlling major programs that have a distinct beginning and end.) Back to Board
