Engineering design is a systematic, intelligent process in which engineers generate, evaluate, and specify solutions for devices, systems, or processes whose form(s) and function(s) achieve clients’ objectives and users’ needs while satisfying a specified set of constraints. In other words, engineering design is a thoughtful process for generating plans or schemes for devices, systems, or processes that attain given objectives while adhering to specified constraints.

Introduction to Engineering Design
- 1. Design & Engineering BE-102 Naseel Ibnu Azeez.M.P Asst. Professor, Dept. of Mechanical Engineering, MEA-Engineering College, Perinthalmanna. Email: naseel@live.com
- 3. You Can Find Design Everywhere and that's why looking for a definition may not help you grasp what it is
- 4. It's what drew you to the last piece of furniture you bought
- 5. It is there in the last dress you brought……..!
- 6. it's what made online banking possible………!!!
- 7. You can see it on your Mobile phones
- 8. It is what determines the beauty of constructions
- 9. It is even controlling traffic……!
- 10. It safeguard power transmission process
- 11. It is running the whole Automobile industry !!!
- 12. Design in Nature
- 13. Human activities characterized as design
- 14. Design is conceiving and giving form to artefact's that solve problems………
- 15. Design is not mathematics !!! 𝑓 𝑥 = 𝑎0 + 𝑛=1 ∞ 𝑎 𝑛 cos 𝑛𝜋𝑥 𝐿 + 𝑏 𝑛 sin 𝑛𝜋𝑥 𝐿 𝑥 = −𝑏 ± 𝑏2 − 4𝑎𝑐 2𝑎
- 16. Yes….Design is a Science too Knowledge ascertained by observation and experiment, critically tested, systematized, and brought under general principles
- 17. Design using technology but it is not only technology ! Technology is the branch of knowledge which deals with the conversion of raw materials into articles of utility. This requires knowledge about: o Materials o Methods o Tools and equipment's
- 18. It is not 100% Engineering Engineering is the application of mathematics, empirical evidence and scientific, economic, social, and practical knowledge in order to invent, innovate, design, build, maintain, research, and improve structures, machines, tools, systems, components, materials, and processes. Or Arts and science of utilizing the forces and materials of nature for the benefit of mankind and for the direction of man’s activities towards this end.
- 19. You can find elements of Art in Design Art is the expression or application of human creative skill and imagination, typically in a visual form such as painting or sculpture, producing works to be appreciated primarily for their beauty or emotional power.
- 20. Design is the combination of Science, Technology, Engineering & Arts
- 21. Simple Designs are the most complex !!! Here, the combination occur Science+Engineering+Technology+Art Why we are using wooden handle for hammer/axe …?
- 22. Science, Engineering, Technology & Art Science gives the Principle for temperature measurement -Thermal expansion of solids and liquids Engineering uses this principle to design a thermometer Technology bring the concept into real world Art make it comfortable and more ergonomic
- 23. Why Design?
- 24. Design brings solutions for too may problems
- 25. Design integrate Creativity with Technology
- 26. Consider you have a steel wire of 5mm diameter What you can do with it?
- 46. Design is a dynamic process it keep improving products Improvements in Functioning Strength Durability Effectiveness Economy Comfort & Ergonomics Aesthetics
- 50. There is no ultimate designs !!! Still you got a chance on everything around you !
- 51. You are the Superhero
- 52. How Design?
- 53. Through Human activities resulting from • Observations and identify the problem • Experimentations • Logical thinking and Judgment • Organizing results under general principles • Application of principles • Manipulations
- 54. The Greatest Designer….? How to observe …?
- 56. NATURE IS FULL OF INFINITE CAUSES THAT HAVE NEVER OCCURRED IN EXPERIENCE - LEONARDO DA VINCI
- 57. Life forms
- 58. Plants Grass and Bush Cactus Ornamental plants Tree Creeper
- 61. Devices or Contrivances Holding : Leg Holding : Beak + Legs Javelin Cutting tool

- 107. … and so, Humans learned design basically from the Nature… and he continues to do so… Its there in your blood !!!
- 108. Experimentations • It test the viability of theoretical assumptions • It trace out possible errors and improve product • It may leads to new ideas and innovations
- 109. Logical thinking and Judgment Logic requires the act of reasoning by humans in order to form thoug and opinions, as well as classifications and judgment
- 110. Organizing results under general principles Collective thinking Mapping requirements and principles Analyse the results Re engineer the idea based on results
- 111. Application of principles Lets do it Integration of Science, Technology & Art through Engineering Still you may face different problems keep solving issues After optimization you will have your product
- 112. Manipulations There is no ultimate designs keep improving your product Integrate added advantages Try alternate solutions
- 113. Observations and identify the problem Experimentations Logical thinking and Judgment Organizing results under general principles Application of principles Manipulations
- 114. Let's Design
