Design Technology 1109 NotesDesign Technology 1109 NotesPlanning: a systematic, organized method of approaching a problem. In the context of this course, planning means following the Design Process.
3 Components of Design
1) Creative - the expression of a person’s ideas.
- is unique to an individual.
2) Technical - the application of technology to the resolution of the design idea.
3) Aesthetic – relates to how pleasing a design is to look at.
A good design expresses a person’s creativity with a balance of technical quality as represented by the functionality of the product, and of aesthetic quality.
Functionality: is a measure of how well the product meets the needs, as expressed in the design problem.
Aesthetic Quality: is determined through the use of both the principles and elements of design.
Principles of Design:
- Emphasis
- Balance
- Proportion
- Rhythm
Elements of Design:
- Colour (hue, tent, saturation)
- Shape/Form
- Line
- Texture
Design: - Plan to solve a problem.
- Visual communication of an idea.
Science: the study of natural events.
Technology: - is the practical application of scientific knowledge… it uses resources and information to produce goods and services.
- the evolution of scientific knowledge is often (especially now) dependent on new and emerging technology.
Technology can de defined as resources/knowledge, process (the activity of development and use of technology), as well as the product (output).
- People
- Time
- Information
- Knowledge
- Capital
- Tools/Machines
- Materials
There are four types of system outputs: for more detail, click here to visit Integrated Systems 1205 notes.
To solve technological problems, especially concerning Design Technologies, we employ the Problem Solving Model.
Design Technologies: those materials that can be used to express ideas through the design process and which can be used to generate a solution to a technological problem.
Symbols:
- Used to represent objects when drawing the actual object would be superfluous; too time consuming, to difficult, or place too much information on drawing.
- Symbol sets exist for pretty much every specialized area like plumbing, electrical, woodworking, etc.
Alphabet of lines:
Visualization: the process of looking at drawings which may include various pictorial renderings, various views of an object, assorted sectional views, and detail drawings, and creating a mental image of what the object is, what it looks like, how it is assembled and possibly how it works.
Two basic methods of presenting visual designs of objects are:
1) Pictorial or isometric: where a three dimensional image is prepared (ie. a “picture”)
2) Orthographic or multiview: observe an object from various sectioned views to gain a clear picture of all dimensions and measurements. Represented in only two dimensions per view: usually top, side, and end.
Protection lines: __________________
A thin line used by designers to establish a relationship between dimensions of the same object in multiple views.
Dimensions:
- Used to indicate the size of various components of an object.
- Dimensions are placed on drawings according to rules, which exist to keep the drawing from becoming too confusing.
Notes: Exactly what the name indicates. Notes provide additional information that is pertinent to the understanding of a drawing.
Labels: very simple names attached to drawings. They are used to identify views, sections, details, and drawing sheets in series of drawings.
