What is Brainstorming?
A group technique for solving problems, generating ideas, stimulating creative thinking, etc. by
unrestrained spontaneous participation in discussion.
What are Constraints?
1. A limit to a design process. Constraints may be such things as appearance, funding, space,
materials, and human capabilities. 2. A limitation or restriction.
What is the Decision Matrix?
A tool used to compare design solutions against one another, using specific criteria.
What is a Design Brief?
A written plan that identifies a problem to be solved, its criteria, and its constraints.
What is the Design Process?
A systematic problem-solving strategy, where multiple solutions are devised that will be
narrowed down to one based on critera and constraints of the design.
What is a concept sketch?
A graphical representation of an idea that can quickly communicate design intent and details
with tonal shading.
What is an Engineering Notebook?
A book in which an engineer will formally document, in chronological order, all of his/her work
that is associated with a specific design project
,What is a measurement?
Is the best estimate of a quantity
What is an Innovation?
An improvement of an existing technological product, system, or method of doing something
What is an Invention?
A new product, system, or process that has never existed before, created by study and
experimentation.
What is a Dimension?
A measurable extent in a particular direction, such as the object's width, height, and depth.
What is an Isometric?
A form of pictorial sketch in which all three drawing axes form equal angles of 120 degrees with
the plane of projection.
What is a multiview drawing?
A drawing which contains views of an object projected onto two or more orthographic planes.
What is a Orthographic Projection?
A method of representing three dimensional objects on a plane having only length and breadth.
Also referred to as Right Angle Projection.
What is a Pictorial Drawing?
A sketch that shows an object's height, width, and depth in a single view.
What is a Perspective Drawing?
A form of pictorial sketch in which vanishing points are used to provide the depth and distortion
that is seen with the human eye.
What is an object line?
Thick and dark and Define the object
What is a construction line?
Very lightly drawn lines to guide drawing other lines and shapes
What is a hidden line?
,Show interior detail not visible from the outside of the part
What is a Projection Line?
An imaginary line that is used to locate or project the corners, edges, and features of a three-
dimensional object onto an imaginary two-dimensional surface.
What is an Accuracy?
The degree of closeness of measurements of a quantity to the actual (or accepted) value.
What is Frequency?
The rate at which something occurs over a particular period or in a given sample.
What is a Histogram?
A graph of vertical bars representing the frequency distribution of a set of data.
What is the 1st quartile?
median of the first half of the data.
What is the 3rd quartile
median of the upper hald of the data
What is the Mean?
A measure of center in a set of numerical data, computed by adding the values in a list and then
dividing by the number of values in the list.
What is the Minimum?
Smallest value of the data set.
What is the Maximum?
Largest value in the data set.
What is the Median?
A measure of center in a set of numerical data. is the value appearing at the center of a sorted
version of the list - or the mean of the two central values if the list contains an even number of
values.
What is Mode?
The value that occurs most frequently in a given data set.
, What is Precision?
The degree to which repeated measurements show the same result.
What is Scale?
1. A straight-edged strip of rigid material marked at regular intervals and used to measure
distances. 2. A proportion between two sets of dimensions used in developing accurate, larger
or smaller prototypes, or models of design ideas.
What are Significant Digits/figures?
The digits in a decimal number that carry meaning contributing to the precision or accuracy of
the quantity.
What is a Design Statement?
A part of a design brief that challenges the designer, describes what a design solution should do
without describing how to solve the problem, and identifies the degree to which the solution
must be executed.
What is a Prototype?
A full-scale working model used to test and improve a design concept by making actual
observations and necessary adjustments.
What is a Scale Model?
An enlarged or reduced representation of an object that is usually intended for study purposes.
What are Working Drawings?
Drawings that convey all of the information needed to manufacture and assemble a design.
What is a Through/thru hole?
Hole cuts through entire thickness
What is a clearence hole?
Hole large enough to allow screw head (and driver) to pass through
What is a blind hole?
A hole that does not cut through the entire thickness
What is a countersink hole?
