What is Design?to fashion after a plan - Webster's dictionary to design is to create something that has never beenalthough engineers are not the only people who design thingsTo design is to pull together / synthesis something new or to arrange existing things in a new way to satisfy a recognized need of society2

DesignGood design requires both analysis and synthesisUnderstand how the part will perform in serviceAble to calculate expected behavior before it exists in physical form by using the appropriate disciplines of science and engineering and the necessary computational tools ANALYSISIdentification of the design elements that will comprise the product into workable system - SYNTHESIS3Engineering Design ProcessStarts with recognition of the need for the product.Both design and redesign require knowledge of the intended use of the product, plus information on theMarketTechnical dataMaterials and productionFor any product design you are part of a team!!!

Engineering Design Process contnDetermine the needStarts with recognition of a needSketching of the solution (product) is very useful during this step.Establish known informationIncludes gathering information on aspects of the products such as possible materials, market analysis, ability to manufacture, cost to manufacture, etc.

5Engineering Design Process contnStimulate Design ConceptsConsider the various aspects in the manufacture of the product such as material, shape, etc.Investigate Design Concepts with Analytical ToolsUse modern methods and tools to analyze design alternatives.

6Engineering Design Process contnGather all information and reviewGather together all information and design alternatives and review so that decisions can be made.Test the design that appears best.Accept, Modify, or RejectOptimize the design by iteration7Types of DesignOriginal design - innovative design, It employs an original, innovative concept to achieve a needAdaptive design - adapts a known ' solution to satisfy a different need to produce a novel applicationRedesign - improve an existing design8Types of DesignSelection design - design task consists of selecting the components with the needed performance, quality, and cost from the catalogs of potential vendorsIndustrial design - improving the appeal of a product to the human senses, especially its visual appeal, more artistic than engineering
