Engineering Design Utilizing the Engineering Design Process
Engineers Follow A Process The Engineering Design Process is a step-by-step problem-solving strategy, with criteria and constraints, used to develop many possible solutions and then choose the best one. A Review…
The Engineering Design Process
What is the problem? What exactly are you being asked to do?
What are the requirements? What MUST your solution do? (Be a certain size? Hold a certain amount of weight?)
What are the constraints? A constraint is a limit to the design process. It may be things such as appearance, funding, space, material, and/or human capabilities.
Brainstorm Ideas Brainstorming is a method of shared problem solving in which all members of the group spontaneously generate ideas in an unrestricted discussion
Choose the Best Idea Discuss your ideas. Determine if they meet the requirements and constraints. Then use a matrix to compare each idea and decide which one is the best.
Option- List the things that are good about this design. List the things that are not so good about this design. Design Comparison Chart
Draw Your Design Create a detailed drawing that clearly shows what your solution will look like. This should include the exact criteria for your design. Criteria is the desired specifications(elements or features) of a product or system.
Gather Your Materials Make sure you have everything you will need to create your design.
Follow Your Plan Use your drawings and materials to actually build, create, prepare, etc. your design.
Test It Out Try it and analyze the outcome. Analyze means to examine carefully and in detail so as to identify causes, key factors, possible results, etc.
Does it meet the requirements? If not, begin the process again to find a solution to this problem. If so, begin the process again to make it better.
Does it meet the constraints? If not, begin the process again to find a solution to this problem. If so, begin the process again to make it better.
Are You Ready to Apply This to A Real Life Situation?
You go out for a nice helicopter ride…
What do you do?
A Helicopter Can Land Safely if the Engine Shuts Down while in Flight. How?
The state of flight where the main rotor system Is being turned by the force of the relative wind rather than engine power
the study of forces and the resulting motion of objects through the air
the force that directly opposes the weight of an airplane and holds the airplane in the air
the force generated by the gravitational attraction of the earth on the aircraft; lift must be equal to weight in order to sustain flight.
a force applied to a body to propel it in a desired direction; the force which moves and aircraft through the air
Resistance of the air (technically a fluid) against the forward movement of an airplane
