Vacuum Waste Collection Vehicle Auxiliary Power Generator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile waste collection systems face challenges in efficiently and cost-effectively supplying power to electric agitators in waste storage tanks, particularly due to the need for long and expensive electric supply lines and coordinating power supply across multiple housing estates with shared waste collection points.
Innovation Solution
A vacuum operated waste collection system with a vehicle-mounted auxiliary electrical power generator that supplies power directly to the agitator through a stationary waste pipe system, eliminating the need for external power connections by integrating an electrical connection interface in the docking station, allowing for automatic power delivery only when a tank with an agitator is connected for emptying.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If long electric supply lines are drawn from available supply points to waste storage tanks, then electric power can be supplied to agitators, but installation costs and system complexity increase significantly
Solution Approach 1:
The patent combines the vacuum vehicle's mobile power generator with the waste collection system, merging the power supply function into the existing mobile platform. This eliminates the need for separate external power lines by utilizing the vehicle's onboard generator to power agitators through the existing vacuum pipe infrastructure.
Solution Approach 2:
The system enables self-service by allowing the vacuum vehicle to generate and supply its own power to the agitators during waste collection operations. The mobile generator on the vehicle serves the power needs of the connected tanks without requiring external power infrastructure.
2Ease of operation
If external power connections are installed for waste storage tanks, then agitators can be powered, but installation expenses and coordination across multiple housing estates increase
Solution Approach 1:
The vacuum vehicle serves multiple functions: waste collection through vacuum suction and power supply to agitators. The mobile generator and control system are integrated into the vehicle, allowing it to universally serve multiple tanks across different housing estates without requiring separate power installations for each location.
Solution Approach 2:
The vacuum pipe system acts as an intermediary medium that also serves as the power transmission pathway. Electrical conductors are integrated within the existing vacuum pipe infrastructure, using the established connection route to deliver power to tanks without requiring separate external power lines.
3Device complexity
If mobile power supply is used instead of fixed power lines, then installation costs are reduced, but power supply reliability must be maintained
Solution Approach 1:
The system transitions from a static power supply infrastructure to a dynamic mobile power supply. The generator on the vacuum vehicle can move to different locations and connect to different tanks as needed, providing flexible and reliable power supply adapted to the actual operational requirements of waste collection.
Solution Approach 2:
The control system monitors the connection status and operational needs of tanks, automatically controlling the generator's output and connection. This feedback mechanism ensures that power is supplied reliably only when and where needed, maintaining system reliability while optimizing power supply efficiency.
