## 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
5. Flywheel
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)
