Problem Statement and Concept

Our project for the semester consists of creating an automated can crushing machine. The purpose of the machine would be to easily load and crush a standard size alumnium beverage can. If possible we would like to be able to load and crush multiple cans in succession.

In order to automate this process many machine elements will be included:

1. Electric Motor
2. Quick Return Mechanism
3. Gearing\gear reductions
4. Linkages
5. Flywheel
6. Mechanical advantage parts
7. Bearings

Customer Requirements and Engineering Specifications

Number	Customer Requirements	Engineering Specifications	Target (units)	Verification/Validation
1	Easily mountable (Basic)	Time to mount(min) [Estimate the time to mount based on the geometry/complexity and number of parts]
2	Be able to crush cans quickly	Cans per minute (15) [Using Working Model, it will be possible to simulate the can crusher and time how many cans it can crush in one minute]
3	Standard alumunium cans. ie. Beer, Soda, Juice	Dimensions and material properties (cm,yield strength) [Measure actual cans and check their material property]
4	Minimal jamming	Rate (jams/100,1000) crushes [Estimate how many jams the can crusher will have based on the geometry/complexity of the can]
5	Crush cans to a certain thickness	Average thickness of crushed can (cm) [Set the can crusher to a certain displacement when crushing a can guaranteeing the can will be of a certain thickness when it is crushed]
6	Not very loud	Decibels (dB) [Do a sound test while crushing a can under similar circumstances as the automatic can crusher]
7	Reasonable size	Dimensions/Volume (cm/cm^3) [Measure dimensions in Working Model]
8	Reasonable cost	Dollars ($) [Estimate cost based on physical parameters of can crusher]
9	Aesthetics	Customer satisfaction survey (%) [Conduct a survey on people based on what the design concept of the can crusher looks like]
10	Durable	Number of crushes until failure (#) [Estimate the durability of the can crusher based on physical parameters of the machine]
11	Safe (Child Proof)	No. of sharp edges, finger size openings (#)(cm)
