TRASH TRAP
VIRTUAL PROTOTYPE PRESENTATION

2. INTRODUCTION
● The Waterwheel rubbish Trap captures floating rubbish to protect rivers and aquatic life.
Its hydrodynamics and simple mechanical design traps and holds trash like plastic bottles,
bags, and leaves.
● The Waterwheel Trash Trap collects floating garbage using water's natural movement. A
massive waterwheel or conveyor belt moves, helped by the water stream, slowly
accumulating waste. Authorities may easily dispose of gathered rubbish by putting it in a
bin or container.

CONSIDERATION

7. DFMA
● Minimize Part Count: Reduce the number of individual parts in the design as much as possible.
● Design for Standardization: Utilize standard parts and components wherever possible.
● Design for Safety: Incorporate safety features into the design, such as proper guards or fail-safe
mechanisms, to protect both the operators and the end-users of the waterwheel trash collector.
● Design for Sustainability: Consider the environmental impact of the manufacturing and assembly
processes.
● Design for Quality: Implement features that ensure high-quality assembly, such as self-aligning
parts or foolproof design elements that prevent incorrect assembly.
● Modular Design: Utilize a modular design approach, dividing the waterwheel trash collector into
sub-assemblies that can be manufactured and assembled independently.
● Design for Tooling: Consider the required tooling for manufacturing and assembly processes.
● Design for Ease of Manufacturability: Simplify the manufacturing process by designing
components that can be easily produced using standard manufacturing techniques.

8. HUMAN FACTOR
● Safety Considerations :
The remote control system should incorporate safety features to protect both the operator and the
environment. Proper safety training and guidelines should be provided to operators to ensure safe operation.
● Ergonomics :
The design of the remote control device should take into account ergonomics to minimize operator fatigue and
discomfort during prolonged use. The device should be designed with appropriate button layouts, sizes, and
tactile feedback to ensure comfortable and efficient operation
● Maintenance :
Regular maintenance and repairs are essential for the smooth functioning of the Waterwheel Trash Trap. They
ensure that the collector remains in good working condition and can promptly address any technical issues.
● Environmental Considerations :
Humans need to be knowledgeable about the environmental impact of the Waterwheel Trash Trap. Human
operators can make informed decisions to minimize these impacts and prioritize environmentally responsible
collection practices.
● Continuous Improvement and Innovation:
Human factors contribute to the ongoing improvement and innovation of the Waterwheel Trash Trap. By
actively engaging with stakeholders, listening to feedback, and incorporating new technologies or design
enhancements, manufacturers can develop more efficient and user-friendly versions of the device.

10. ENGINEERING ANALYSIS

11. ASSUMPTION
• Waterwheel Trash Traps can run for 1 hour long.
• Maximum load capacity can be load in trash box is 7 kg.
• The battery used are D-type 13A
• The material for trash box is Plastic PP(homopolymer, low flow)

12. CALCULATIONS
Calculate the power consumption for motors
Therefore, the battery capacity needed for the RC boat to
run for 1 hour is 0.675 Watt (W)
● (assuming the battery voltage matches the motor voltage)
Have 3 motors
● P = V*I
● P1 = 1.5V*0.15A
● P1 = 0.225 Watt
Calculate the battery capacity in milliamp-
hours (mAh)
● Capacity = 12A * 1 hours *
1000
● Capacity = 12,000 mAh
= 0.225 Watt x 3 motors
Total Power Consumption =0.675 Watt
Therefore, the battery capacity needed for Water
Wheel Trash Trap with three motors, each rated at
0.15 A and 1.5V, to run for 1 hour is 12,000 mAh.

• Details of Plastic PP materials:
• Base on analysis using Ansys Workbench, by
applying 70 kg load for all surface of inside trash box,
it is found that factor of safety is 3.4503 which is
greater than 1, meaning that the part is safe.
