The "Friendly" Mouse Trap


Context

"EEK!!! Help there's a mouse in the house!" Oh no, that's one of your parents freaking because one of those disease ridden,
smelly, dirty rodents is in your house. They don't want to kill it, but they don't want to touch it either. How can you help them get
rid of this common household pest?



Problem

In groups of 2, design a mousetrap that is both mouse and user friendly.



Design Constraints

          Maximum length of 30cm
          Maximum height of 15cm
          Maximum cost of materials used: $4.00
          Must be made of 75% recycled materials
          Must be mouse friendly (mouse can be released unharmed)
          Must be user friendly (operator can release mouse without having to touch it)
          Must be reusable
          Deadline May 13, 1999



Design Considerations

          Is it user friendly? - Keep it simple
          Use appropriate material
          Mouse resistant (gnawing, etc.)
          Long lasting
          Add a personal touch in the design (feelings, style, likes, etc.)
          Keep in mind the inside and how it will affect the mouse
          Make your mousetrap presentable and something you'd want to buy



Sequence

        1.Brainstorm different ideas
        2.Look for and select materials
        3.Develop an idea from your brainstorming sketches
        4.Sketch your idea. Is it feasible?
        5.Make a final orthographic drawing of your selected solution
        6.Make a working drawing of your mouse trap
        7.Build a paper model of your mousetrap. Will it work?
        8.Begin construction
        9.Test the finished prototype
       10.Make necessary modifications
       11.Personalize your product



Management Issues

End of day 1: Check student progress? Are they on track?

End of day 2: Approve preliminary sketches

End of day 3: Students should have begun orthographic drawing

End of day 4: Verify final and working drawings

End of day 5: Model should be completed

End of day 8: Trap finished and handed in
