11 The Design Process

12 The Problem 1. May have to invent a solution to a problem 2. May have to change an existing design

13 Investigation FUNCTION: Must solve the problem described in the design brief. What exactly is the use of the article? FUNCTION: Must solve the problem described in the design brief. What exactly is the use of the article? APPEARANCE: Shape, color, and texture should make the object attractive. APPEARANCE: Shape, color, and texture should make the object attractive. MATERIALS: Availability? Cost? Physical Properties (strength, rigidity, color, durability) MATERIALS: Availability? Cost? Physical Properties (strength, rigidity, color, durability) CONSTRUCTION: Hard to make? CONSTRUCTION: Hard to make? SAFETY: The object must be safe, should not cause accidents SAFETY: The object must be safe, should not cause accidents

14 Developing Alternative Solutions Write or draw every idea on paper as it comes to you Write or draw every idea on paper as it comes to you The more ideas you have, the more likely you are to end up with a good solution The more ideas you have, the more likely you are to end up with a good solution

15 Choosing a Solution Your own skills Your own skills The materials available The materials available Time needed to build each solution Time needed to build each solution Cost of each solution Cost of each solution

16 Detailed Drawing Overall dimensions Overall dimensions Detailed dimensions Detailed dimensions Material to be used Material to be used How it will be made How it will be made What finish it will require What finish it will require

17 Models and Prototypes Model is a full-size or small- scale simulation of an object Model is a full-size or small- scale simulation of an object Prototype is the first working version of the designers solution Prototype is the first working version of the designers solution

18 Testing and Evaluating Does it work? Does it work? Does it meet the design brief? Does it meet the design brief? Will modifications improve the solution? Will modifications improve the solution?

19 Manufacturing How many to make? How many to make? Medical equipment produced in hundreds, nuts and bolts produced in millions Medical equipment produced in hundreds, nuts and bolts produced in millions

20 What is Technology?

21 What Counts as Technology? Objects Objects Knowledge Knowledge Activities Activities A Process A Process Sociotechnical System Sociotechnical System

22 Technology is Related to Science Purpose of technology: change in the material environment Purpose of technology: change in the material environment Purpose of science: understanding of nature. Purpose of science: understanding of nature.

23 Technology Involves Design Design is the center of technology Design is the center of technology Design process: begins with perception of a need, continues with formulation of a specification, and ends with an evaluation of the solution. Design process: begins with perception of a need, continues with formulation of a specification, and ends with an evaluation of the solution.

24 Technology Involves Making Motivating factor: desire to fulfill a need. Motivating factor: desire to fulfill a need. All designs should be made or realized. All designs should be made or realized. If the need is to be fulfilled, the design is to be evaluated, and the design activity is to have been purposeful and worthwhile. If the need is to be fulfilled, the design is to be evaluated, and the design activity is to have been purposeful and worthwhile.

25 Technology is Multi-Dimensional Technology is performing a multitude of functions Technology is performing a multitude of functions Examples: working with others, operating within budgets, persuading decision makers, communicating to clients and working to deadlines. Examples: working with others, operating within budgets, persuading decision makers, communicating to clients and working to deadlines.

26 Technology is concerned with Values Value decisions may be called for not only in relation to the specific design criteria, but also in relation to the rightness or wrongness of a particular solution in ethical terms. Value decisions may be called for not only in relation to the specific design criteria, but also in relation to the rightness or wrongness of a particular solution in ethical terms.

27 Technology is Socially Shaped Determined by social interests. Determined by social interests. Technology is shaped by society, by consumer choice. Technology is shaped by society, by consumer choice. Technology can shape society. For example, the technology of the motor car has shaped our environment and our whole way of life. Technology can shape society. For example, the technology of the motor car has shaped our environment and our whole way of life.

28 Technology and Science, go way back… The word science is derived from the Latin word scientia, which simply means knowledge, and the German word wisenschaft, which means systematic, organized knowledge. (Why?) The word technology is derived from the Greek words, techne and logos, which means art or craft. (How?) Science has a relatively recent history – perhaps four centuries, whereas technology has a much longer history, a history as long as humanity.

29 How Technology and Science are related… TechnologyScience Goal: the creation of artifacts and systems to meet people's needs Goal: the pursuit of knowledge and understanding for its own sake Design, invention, production Discovery (controlled by experimentation) Analysis and synthesis of design Analysis, generalization and creation of theories The search for and theorizing about new processes (e.g. control; information) The search for and theorizing about cause (e.g. gravity; electromagnetism) Taking good decisions based on incomplete data and approximate models Drawing correct conclusions based on good theories and accurate data Design, construction, testing, planning, quality assurance, problem solving, decision making, interpersonal and communication skills Experimental and logical skills
