Tech Design
Term | Definition |
---|---|
Technology | The modification of the natural environment in order to satisfy human needs and wants. |
Technology Literacy | The ability to use, manage, understand, and access technology |
Materials Technology | The technology of producing, altering, and combining materials. |
Information and Communication Technology | The technology of transporting people and goods.The technology of communicating to people and machines. |
Transportation Technology | The technology of transporting people and goods. |
Medical Technology | The technology of caring for the sick and curing disease |
Agriculture and Bio Technology | The technology of farming and DNA. |
Construction Technology | The technology of building and maintaining structures |
Energy and Power Technology | The technology of producing and transferring energy into work/power |
Manufacturing Technology | The technology of producing goods in a factory. |
Science | The knowledge of the natural world (Discovery). Helps us develop technology. |
Invention | A totally new product, produced from ideas and imagination. |
Innovation | An improvement to an invention. You will have more innovations than inventions. |
Positive Outcomes vs. Negative Outcomes | Positive: technology solves problems, Negative: creates new problems |
Systems Model | A group of units/parts that work together. Consists of input, process, output and sometimes feedback. |
Open-Loop System: | A system in which there is no feedback. Input>Process>Output |
Closed-Loop System: | A system in which there is feedback. Input>Process>Output>Feedback |
Systems Thinking: | Viewing problems as parts of an overall system. What component is causing the problem? |
Controls | Mechanisms or steps that are performed using information about the system that cause the system to change. |
Input | Anything put in to a system. Can be capital ($), raw materials, people (labor), fuel, etc. |
Process | The process of changing/using the inputs. Ex. The burning of the fuel to produce power/work in an engine. |
Output | The results of the system. Can be power, movement, a product, etc. |
Feedback | Information about the system that can be used to alter the system. Can be a gauge or other measurements. |
Criteria | The problem you are trying to solve/the goal of your design. Example: Design a bridge. |
Constraint | Limitations to your design. You may have a time limit, money limit or specifications for the appearance. |
Prototype | A full-scale working model of the product. For example the crash car used to test car safety. |
Newton’s 1st Law | An object remains still or remains in motion unless acted upon by an outside force. |
Newton’s 2nd Law | Force = mass x acceleration. The greater the mass, the more force that is needed to move it. |
Newton’s 3rd Law | For every action, there is an equal and opposite reaction |
Mechanical Advantage | A force that is increased by the use of a machine. Ex. using a drill to drive a screw. |
