Technological Design
The development of new technology is called technological design. It is similar to scientific investigation. Both processes use evidence and logic to solve problems. Steps of the technological design process include:
- Identify a problem.
- Research the problem.
- Generate possible solutions.
- Select the best solution.
- Create a model of the solution.
- Test the model.
- Refine and retest the model as needed.
- Communicate the final solution.
Consider the problem of developing a solar-powered car. Many questions would have to be researched in the design process. For example, what is the best shape for gathering the sun's rays? How will the energy from the sun be stored? Will a back-up energy source be needed? After researching the answers, possible designs are developed.
This takes imagination as well as reason. Then a model is made of the best design, and the model is tested. This allows any problems with the design to be worked out before a final design is selected.
Technological design always has constraints. Constraints are limits on the design. Common constraints include laws of nature such as the law of gravity, properties of the materials used, and costs of production. Ethical concerns are also constraints on many technological designs. Like scientists, engineers must follow ethical rules. For example, the technologies they design must be as safe as possible for people and the environment. Engineers must weigh the benefits and risks of new technologies, and the benefits should outweigh the risks.
