5. Mechoptronics How WOULD You Define Engineering?

6. Questions to be Answered What is its objective ? How does it function/operate ? On what is it based ? How are its goals achieved ? What are its consequences/results?

7. Wikipedia Definition Engineering is the design, analysis and/or construction of works for practical purposes. One who practices engineering is called an engineer. . . . . . Engineers use imagination, judgment and reasoning to apply science, technology, mathematics and practical experience. The result is the design, production and operation of useful objects or processes. The broad discipline of engineering encompasses a range of specialized sub-disciplines . . . .

8. New Definition A profession that applies the knowledge base of the physical, mathematical and biological sciences together with practical experience to create practical solutions to the problemsof mankind for the purpose of providing him with a better quality of life together with control and use of the natural resources and the environment in which he exists. Its goal is the creation of physical devices, processes and systems that meet the needs, desires and requirements of man in the society he has developed and lives in.

9. Engineering Disciplines Based on Applicable Sciences • Mechanical Engineering – Physical principles of motion and thermal energy behavior • Electrical Engineering – physics of electricity, magnetism, electronics and digital theory • Chemical Engineering – science of chemical and thermal transformation of materials • Industrial Engineering – management and organizational theory and information processing

10. Mechoptronics How Would you define design?

11. Wikipedia Definition Design . . in the context of . . applied arts, engineering, architecture . . is used both as a noun and a verb. “Design” as a verb refers to the process of originating and developing a plan for a new object (machine, building, product, etc.). As a noun, “design” is used both for the final plan or proposal (a drawing, model or other description), or the result of implementing that plan or proposal (the object produced). Designing normally requires considering aesthetic, functional, and many other aspects of an object, which usually requires considerable research, thought , modeling, interactive adjustment and re-design. Design as a process can take many forms . .

12. New Definition (Design) An iterative creative activity, also undertaken by Engineers, that results in the production of the description and specifications of a device, system or process that meets some recognized or identified need of society based on existing technology and science while making use of available resources within some set of constraints applicable to the circumstances in question.

13. Mechoptronics How would you define design engineering

14. Design Engineering (Mechoptronics) Design Engineering applies the practices and methodologies of creativity/innovation, operational analysis and decision making skills together with the appropriate scientific and technological knowledge base to the solution of real engineering problems taking into account the available resources and constraints of the circumstance in question.

15. Conclusion • Design Engineering as a discipline consists of the collection of practices, methodologies and synthesis skills used to carry out the engineering design process. • Creativity and Innovation, Operational Analysis and Decision Theory are basic to the Design Engineering skill set. • The fundamentals of Design Engineering are similar for all engineering disciplines although the underlying disciplinary science knowledge base is different.

21. Synthesis versus Analysis • Synthesis entails the act of creating something that did not exist before by integrating information that has been learned. • In other words, when we put together a whole series of skills, we say we are synthesizing those skills. • Synthesis is very similar to analysis. When a person analyzes they determine the key components of the argument. In many situations, a person analyzes while synthesize.

22. Examples of Synthesis Objectives • Mathematics: Apply and integrate several different strategies to solve a mathematical problem. • Arts/Music: Create a painting that uses various principles of perspective to achieve a specific effect. • Science:Apply multiple physical principles to solve new scientific problems. • Mechoptronics?????

25. Mechoptronics Introduction Introduction to the Design Cycle Design Approaches Design Brief and Product Design Specification

26. IB Design Cycle Model (DCM)

27. Design Cycle Model (DCM): A Systematic Activity • Investigation • Identifying or Clarifying a Need or Opportunity • Analyzing, Researching and Specifying Requirements • Innovation and Inventiveness • Generating Ideas and Possible Solutions • Operational Analysis • Developing and Refining the Chosen Solution • Product Development • Realizing or Manufacturing the Chosen Solution • Decision Making • Testing and Evaluating the Chosen Solution

28. Convergent Nature of the Design Process Top-Right: “The first nebulous idea evolves in the client’s mind into an ill-defined problem.” Middle: “This is presented to the designer as a brief and the design process produces a well-defined solution, which eventually results in a specific object” Bottom: “The development or existence of this object might spark off more nebulous ideas…”

29. Design Approaches or Solution Methods • Incremental Design – Process of taking an existing product and making it better • Radical Design – Innovation-driven creativity • Convergent Thinking – Application of knowledge or research gathered, and then applied, to “converge” or focus on arriving at the single best solution to a proposed problem (very analytical) • Divergent Thinking – Creative approach to problem solving where a range of alternative, creative, unusual or innovative solutions to a problem are considered

35. Information Retrieval • What are some sources of information? • Clarify in what situation to use each?

36. Design Specification • Consists of researched information related to the product (produced by the designer) • Clarifies ideas and is updated regularly • Not just a list but provides justification for the inclusion of information • Very specific statements not aimed at directing the design but focusing the designer’s attention through statements of restrictions What should you include? Important factors?

37. Questions • What do we need to know to move forward to build a design specification? • What are the most important factors for your specific project? • What type of design approach will we take?
