Summary

  • Team Roles

  • Team Constitution

  • Timeline

  • 10 steps of 12-step Design Process

  • Background/Justification

  • Customer

  • Scope

  • Deliverables


Team Roles

Roles

  • Leader- Nate Kunzer

  • Scribe- Keval Amin

  • Scribe- Charvee Makwana

  • Timekeeper- Grant Wetherton


Team Constitution

  • Respect each other

  • Avoid blaming others for any failures

  • NO idea will be ridiculed

  • NO ONE member will dominate over others

  • Respect each others opinions


Timeline


Problem Statement

  • Work for Alpha Engineering Company

  • Disposition needs to be reduced by 70%

  • Failure to do so results in $.05 penalty per can

  • Device that crushes cans to as little as 30% of their original size


Background/Justification

  • Have to reduce 70% of can disposition

  • For every can not crushed; $0.05 penalty


Customers

  • Alpha Engineering Company

  • Mr.Pritchard- ITC Teacher


Scope

Resources

  • Ms. Hernacki- dimensions, calculations

  • Mr. Hund- CAD

  • Mr. Pritchard- Building, dimensioning

    Materials

  • Aspen wood

  • Ply wood

  • Nails

  • Wood Glue


Scope (cont)

  • Customer Constraints

    • 18”x24”x30”.

    • one simple machine.

    • can must fall into bin

    • No human intervention

    • can bin must slide in and out.

    • Must be manually operated.


Deliverables

  • Technical Report

  • PowerPoint Presentation

  • Final Can Crusher

  • CAD Drawings


Brainstorming

  • History of Can Crushers

  • Self-Loading system

  • Purpose of a can crusher

  • Relation to real world

  • Amount of cans crushed at once

  • Size of hole where cans fall, once crushed


Research & Generate Ideas

We can use the following simple machines…

  • Lever

  • Axle

  • Pulley

    Consider the following when building…

  • Dimensions of an aluminum can

  • What kind of wood will be the most stable


Identify Criteria & Specify Constraints

  • At most must be 18” by 30” by 24”

  • Needs one simple Machine

  • Bin must hold 20 crushed cans

  • Must be manually operated

  • All parts must be fabricated

  • Cans must fall into the bin once crushed

Build Process

  • Can Bin

  • Can Body

  • Stopper

  • Connector

  • Lever

  • Crusher

  • Final Assembly


Test Plan


Prototype

  • Could not always follow build process

  • Helpful and gave ideas in building

  • Some parts did not fit together


Test & Monitor


Refine

  • Bought wood that was stable

  • Re-made handle so that it was longer

  • Re-made entire can crusher

  • Re-made hole in handle


Lessons Learned

  • Adjust to a work group and different people

  • Manage our time and use it wisely

  • Don't procrastinate

  • Problem solve


Summary

  • Communication skills

  • Built can crusher from scratch

  • Problem solved
