Mouse Trap CarFront wheel Design Problem

Design and Drawing for Production
Blocks 3 and 4
Today’s lesson:

Problem: I need a front wheel for my mouse trap car
Design Statement: Design and draw using Autodesk inventor a front wheel for the mouse trap car
Constraints: The size of the wheel should have a 50 mm diameter
• Material: The material that will be used will be rapid prototype medium
• The axle of the wheel must be a 7mm diameter wooden dowel
• Wheel to axle attachment: The wheel must be designed to be fixed tightly so the axle will spin with the wheel.
• Design and manufacture: The wheel design must be made on Inventor using the revolve tool and will be manufactured on a Rapid Prototype machine

Ideas: Use your engineer’s notebook or grid paper to design a front wheel. Your teacher will show you some ways that you can fix a wheel to an axle so that they will rotate together.

The basic design: Open a Standard (mm) IPT file. Use the line tool and the dimension tool to create the profile shown here.
