Six Steps of Problem Solving
And
Engineering Design Process
SVES Colleges of EngineeringUML – ATP
Lecture 2
Step OneResearch the Problem
• Gather all the information needed to consider this project
• Define the Problem• Completion is realized with a
project proposal
Step TwoDefine the Problem
• Study the problem and list as many facts as possible to fully define the problem
• Completing the design specifications• Set Objectives• Outcome is a set of specifications
Step Two Develop Design Specifications
Define the Problem
• Specifications are a formal document listing the requirements of a project
• Define details that must be met• Can be used as a guide in future projects• Market Specifications
Develop Design Specifications& Specification Format
• General description• Performance• Power requirements• Packaging• Environmental• Operation• Project and production cost• Agency approvals• Special requirements
Develop Design SpecificationsPackaging
• Mechanical size limits• Environmental rating• Shape• Material• Human engineering aspects
Develop Design SpecificationsEnvironmental
• Ambient temperature• Humidity• Vibration• Shock• Electromagnetic interference (EMI)
– Immunity– emissions
Develop Design SpecificationsManufacturing Cost Goal
• Total cost of purchased parts• Labor cost to manufacture• Manufacturing overhead
• The projected costs should be stated at the volume of manufacture for the costs
Develop Design SpecificationsSoftware
• Outline of the planned method of software operation
• All operations that involve the end user• All operations that involve the hardware• Flow charts ( top level )• Flow charts ( sublevel operations )
Step ThreePlan the Solution
• Develop a Plan• Outline Strategy• List steps intended to solve the problem• Outcome is a Project Schedule
Step FourExecute the Plan
• Preliminary design• Component selection• Breadboarding• Prototype development• Outcome working Prototype
Step FiveVerify the Results
• Test design to set design specifications• Review measured results to specifications• Does it meet the specifications ?• Outcome is a reasonable solution to the
problem
Step SixDevelop a set of conclusions
• Results of the project are summarized• Design improvements and performance
monitoring• Design documentation• Outcome is a Final Report
