What is the Design Process?
1. Define Problem
2. Generate Concepts
3. Develop a Solution
4. Construct and Test Prototype
5. Evaluate Solution
6. Present Solution
What is a Design Process?
A systematic problem-solving strategy, with criteria and
constraints, used to develop many possible solutions to solve or
satisfy human needs or wants and to narrow down the possible
solutions to one final choice.
What is a Design Brief?
A written plan that identifies a problem to be solved, its criteria
and its constraints.
What is a Decision Matrix?
A tool used to compare design solutions against one another
using specific criteria.
What are technical drawings?
Drawings that provide technical information necessary to produce
a product. They include information such as material, size shape,
and assembly, of necessary.
What is a test report?
A report that includes the data and analysis of the prototype
testing.
What are project recommendations?
A list of recommendations to optimize or redesign the solution.
What is a project portfolio?
A collection of documents selected for a specific purpose.
What is an isometric pictorial?
,A type of technical sketch that appears three dimensional
because it shows three sides on an object and is proportional to
the real object being drawn.
What is engineering?
Engineering is the application of mathematics and scientific
principles to better or improve life.
Different types of pictorals
Isometric, Oblique, and Perspective
What is a cavalier oblique pictorial?
An oblique pictorial in which the height, width, and depth are
represented at full scale.
What is a cabinet oblique pictorial?
An oblique pictorial in which depth is represented as half scale
compared the the height and width scale.
What is an oblique pictorial?
A type of technical sketch in which the width dimension is
horizontal.
What is an isometric pictorial?
A type of technical sketch in which the width dimension is not
horizontal and it shows all three sides "equally". Three adjacent
faces share a single point.
What is the box method?
A technique used in sketching to maintain proportionality. Starts
with a sketcher envisioning an object contained within an
imaginary box.
What is a multiview drawing?
A drawing that shows two or more two-dimensional views of a
three-dimensional object.
Width
The measure of an object from side to side.
Height
The measure of an object from top to bottom.
Depth
The measure of an object from the front to the back.
What are perspective drawings?
, A drawing that offers the most realistic 3d view of all the pictorial
methods, since it portrays the object in a manner that is most
similar to how the human eye perceives the visual world.
Different types of perspective representations
one point, two point, three point
One-Point Perspective Drawing
In this type of drawing, there is only one vanishing point on the
horizon line.
Two-Point Perspective Drawing
In this type of drawing, there are two vanishing points, this is the
most common type of drawing.
Three-Point Perspective Drawing
In this type of drawing, the view gets either a worm's eye view or
a bird's eye view of an object.
Perspective
The depth lines recede to a single vanishing point and the width
lines recede toward a vanishing point
What is an orthographic projection?
A technique used to create multiview drawings. Any projection of
the features of an object onto an imaginary plane of projection.
What is a projection plane?
The surface onto which a two dimensional view of a three
dimensional object is projected and created.
Projection Lines
They are used to project each corner outward until they reach the
projection plane.
What are hidden lines.
Hidden edges in each view are indicated by dashed lines.
Construction Line
Very lightly drawn line to guide drawing other lines and shapes.
Object Line
Defines the object, thick and dark.
Hidden Line
Shows interior detail not visible from the outside of the part.
Center Line
