Design By evolution

žOr Traditional design

žIt Means Making Slight Modifications In Exiting Designs

žIn The Past Designs Used To Evolve Over Long Spans Of Time. The Leisurely Pace of Technological Change Reduced The Risk Of Making Major Errors.

žA Designer Does Not Require Much Of Its Analytical Capabilities.

žExample- Development Of Bicycle From Its Crank Operated Version To Its Present Day Chain And Sprocket Version, Took Almost More Than A Century.

žAs We Can See Bicycle Already Exists from More Than A century And Its Present Version Only With A Slight Modifications That  Too Took A Very Long Time.

žThis Was Typical “Example Of Design By Evolution”.

Disadvantages Of Design By Evolution

žUnsuitability For Mass Production.

žLimited to Village Level i.e., limited to Smaller Areas . Unacceptable At Urban Level i.e., Cannot Serve The Needs Of Larger Areas.

žMore Wastage Less Use.

žDifficulty in Modification- A design by Evolution Is Shaped By Demands Of Time. We Cannot Use Sophisticated Tools & Techniques Such As CAD (Computer aided Design) workstation That Can Generate a No Of Alternative Designs Within Minutes.

žEvolutionary Designs Are Slower Process That Cannot meet Today’s Rapidly Changing Needs & Technology.

žUnable To Tap New Technologies- Evolutionary Design Relies Heavily On Small Modifications In An Existing Design.
