Engineering Technology Mr. 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

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

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
