IOT POLY ENGINEERING I1-3 Components: –Goals Humans develop technology to meet needs Each artifact meets more than one goal –Inputs Resources that go into a system and are used by it –Processes Design Process, Production Process, Mgt. Process –Outputs Technological systems are designed to produce specific outputs. Manufactured products, constructed structures, communicated messages, transported people or goods. –Feedback and Control Using information about the outputs to regulate the system. Technology as a System FOT REVIEW

IOT POLY ENGINEERING I1-5 Design Process Design Principles –Design is the result of a formal, sequential process. –Design is mostly driven by profit motive and market. –Design is the result of goal-oriented research. –Designs must be continually checked, refined, and improved. Note: –Design problems seldom arise in a clearly defined form. –Design requirements sometimes compete with each other.

IOT POLY ENGINEERING I1-5 1.Safety – is the product safe to use/construct? 2.Reliability – will it work consistently over time? 3.Cost – is it affordable? 4.Quality Control – does it meet customer requirements? 5.Environmental Concerns – does it harm the natural or human environment negatively? 6.Manufacturability – can it be made? 7.Maintenance – how easily can it be maintained or upheld? 8.Ergonomics – how efficiently can the human body utilize it? Constraints on the Engineering Design Process (A constraint is a limit or restriction)

IOT POLY ENGINEERING I1-5 1.With a partner, choose a technology system. 2.Identify the likely constraints on the design of that system. List the generic 8 constraints, and fill in relevant ideas. Constraints on the Engineering Design Process (A constraint is a limit or restriction)
