3. PROBLEM STATEMENT
The Question
How can we apply what we know about “Theory of Machines”
to our everyday life ?

4. PROBLEM DEFINITION
Issue
 Sustainability
Solution
 Recycling
 Engineers responsibility
 Uncrushed cans waste space
 Small volume-more cans recycled efficiently

5.  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.

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

7. 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.

8. 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.

14. TIMELINE

15. 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)

16. 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.

17. 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.
 Explore Possibilities
 Select an Approach
 Develop a Design Proposal
2) Simulating the 3D Model | Criteria and Constraints
 Maximum space: 200x350x180 mm
 Volume must be 70% less than originally
 At least 1 simple machine
 Manually operated

18. 3D-MODEL SIMULATION (SOLIDWORKS).

19. 3D MODEL

21. MECHANISM MOTION ANALYSIS
It is divided into two categories, which are:
 MATLAB Application: The Mechanism virtual prototype calculations
Displacement, velocity and acceleration equations’ is transfer to MATLAB
modeling.
 Calculations of mechanisms’ degree of freedom, position, velocity and
acceleration of mechanism.
