PROBLEM STATEMENT

The Question

How can we apply what we know about “Theory of Machines”

to our everyday life ?

PROBLEM DEFINITION

IssueSustainability

SolutionRecyclingEngineers responsibilityUncrushed cans waste spaceSmall volume-more cans recycled efficiently

The Machine  refers to the procedures and techniques used to address the three phases of a machine’s lifecycle:

- invention, which involves the identification of a need, development of requirements, concept generation, prototype development, manufacturing, and verification testing;

- performance engineering involves enhancing manufacturing efficiency, reducing service and maintenance demands, adding features and improving effectiveness.

- recycle is the decommissioning and disposal phase and includes recovery and reuse of materials and components.

PROBLEM DEFINITION

We contribute to a more sustainable world by helping people to recycle materials into valuable products.

ORIGIN OF CAN CRUSHER

A can crusher is an instrument used for crushing soda cans.

This is done to make storage easier.

This provides more space in the bin.

The very first can crusher was the human foot.

These can crushers are used in the real world when people or companies that have aluminum cans want to save space in the recycling bin.

BACKGROUND

The can crusher employs a slider-crank as it’s a sliding mechanism. This allows the crusher to exert a larger amount of mechanical leverage to the can. The motor drivers the crank-arm which then slides the piston forward via a connecting linkages.After the piston has crushed the can , the discharge door expel the crushed can into a receptacle below.

TIMELINE

MECHANISM SYNTHESIS AND ANALYSIS

Synthesis : design a mechanism to perform a desired function.

Analysis : given a mechanism, perform kinematics and kinetics analysis (Graphical techniques and Analytical methods)

MECHANISM SYNTHESIS

The drawings are diving into two categories, which are:

1) Sketching: all the ideals for tin can crusher are sketched on the paper to ensure that ideas selection can be made after the selected design choose.

2) Solid Works Application: The design or concept sketched is transfer to solid modeling and drawing using Solid Work Application.
