What is Design?
You Can Find Design Everywhere
and that's why looking for a definition may not help you grasp what it is
It's what drew you to the last piece of furniture you bought
It is there in the last dress you brought..!
it's what made online banking possible!!!
You can see it on your Mobile phones
It is what determines the beauty of constructions
It is even controlling traffic!
It safeguard power transmission process
It is running the whole Automobile industry !!!
Design in Nature
Human activities characterized as design
Design is conceiving and giving form to artefact's that solve problems
Design is not mathematics !!!
Yes.Design is a Science tooKnowledge ascertained by observation and experiment, critically tested, systematized, and brought under general principles
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:MaterialsMethodsTools and equipment's
It is not 100% Engineering Engineeringis 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.OrArts and science of utilizing the forces and materials of nature for the benefit of mankind and for the direction of mans activities towards this end.
You can find elements of Art in DesignArt 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.
Design is the combination of Science, Technology, Engineering & Arts
Simple Designs are the most complex !!!Here, the combination occur Science+Engineering+Technology+Art
Why we are using wooden handle for hammer/axe ?
Science, Engineering, Technology & ArtScience gives the Principle for temperature measurement -Thermal expansion of solids and liquidsEngineering uses this principle to design a thermometerTechnology bring the concept into real world Art make it comfortable and more ergonomic
Why Design?
Design brings solutions for too may problems
Design integrate Creativity with Technology
Consider you have a steel wire of 5mm diameter What you can do with it?
Design is a dynamic process it keep improving products
Improvements inFunctioningStrengthDurabilityEffectivenessEconomyComfort & ErgonomicsAesthetics
There is no ultimate designs !!!Still you got a chance on everything around you !
You are the Superhero
How Design?
Through Human activities resulting from Observations and identify the problem Experimentations Logical thinking and Judgment Organizing results under general principles Application of principles Manipulations
The Greatest Designer.?How to observe ?

and so, Humans learned design basically from the Natureand he continues to do soIts there in your blood !!!
Experimentations
It test the viability of theoretical assumptionsIt trace out possible errors and improve productIt may leads to new ideas and innovations
Logical thinking and Judgment
Logic requires the act of reasoning by humans in order to form thoughts and opinions, as well as classifications and judgment
Organizing results under general principlesCollective thinkingMapping requirements and principlesAnalyse the results Re engineer the idea based on results
Application of principlesLets do it Integration of Science, Technology & Art through EngineeringStill you may face different problems keep solving issuesAfter optimization you will have your product
ManipulationsThere is no ultimate designs keep improving your productIntegrate added advantages Try alternate solutions
Observations and identify the problem Experimentations Logical thinking and Judgment Organizing results under general principles Application of principles Manipulations
Let's Design
