**Problem Solving**Engineering TechnologyMr. Austin**Objectives**• Understand different approaches to Problem Solving • Identify different characteristics of Problem Solving • Enhance vocabulary by using engineering language**How we learned**• Draw a picture Math Problems • “Work Backward”make the end product first then go back and draw it up and forge the design work • Guess and CheckNo effort—just write down a guess and then check the back of the book for congruency**Types of Problem Solving**• Analytical Problem Solving • Creative Problem Solving**Analytical Problem SolvingThe “Scientific Method”**• Define the problem • Gather the facts • Develop a hypothesis • Perform a test • Evaluate the results**Downfall of the Scientific Method**• The process ends when an acceptable understanding of the studied phenomenon is achieved • Once the first solution is found the search is over**Engineering Approach to…The “Scientific Method”**• Define the problem and make a problem statement • Diagram and describe • Apply theory and equations • Simplify the assumptions • Solve the necessary problems • Verify accuracy to required level**Problem Statement**• Restate the problem in your own words • This ensures that you are solving the correct problem • Check your impression to see if it matches the original problem**Description**• Describe the problem and all that is known • List the information given and what needs to be found • This will help you see if you need to find more information than just the solution**Theory**• State the theory or equations needed to solve the problem • Examples are constants and variables like gravity and density**Simplifying The Assumptions**• Makes problem solving easier and still provide an accurate answer • You could go through each scenario or assume the worst and design to that • Swing set example through age groups**Problem Solution**• Perform calculations to solve the problem • Put all of the information together to come up with the best solution**Accuracy Verification**• Estimate the answer • Simplify the problem and solve • Compare with similar problems and previous work • Ask questions • Compare to research • Compare to personal experience • Repeat calculations • Run a simulation • Redo calculation backwards**Estimation**• Provides quick answers to complex problems • Can be used to check an analysis • Becomes better with more experience**Creative Problem Solving**• What is wrong • What do we know • What is the real problem • What is the best solution • How do we implement the solution**What’s wrong**• Defining the issue • Identify if the problem is worth solving • Identify if there is a problem • Restate problem**What do we know**• Gather all the facts • Do not evaluate whether the information is central to the problem • List all facts known • Get help from someone with a different point of view**What Is The Real Problem**• Most overlooked step in the solution process • Identify why the problem exists • Don’t address the symptoms of the problem but rather the root of the problem • The why must be answered**What Is The Best Solution**• Make a list of all possible solutions • Talk with group members or a non bias person about possibilities • The best solution should be decided by a group after a presentation of the information**Implementing The Solution**• Putting the best possible solution into use • Requires a good amount of resources (mostly money) • To implement a solution you must be able to sell the idea**Evaluating The Solution**• Identify what makes an acceptable solution • establish a criterion for success • A neutral party should evaluate the solution to ensure a non bias report • Congruent to feedback in the USM
