Side-Mounted Bin Cleaning With PTO Pressure Washing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional garbage bin cleaning systems are inefficient, labor-intensive, and often require multiple passes for thorough cleaning, leading to water waste and inefficiencies due to separate gas engines, and are limited by rear-mounted designs that cannot navigate narrow spaces.
Innovation Solution
A vehicle-mounted garbage bin cleaning system with a power takeoff driven pressure washing system, featuring a pair of arms for lifting bins into a hopper, and internal and external spray rods with high-pressure rotating nozzles, powered directly by the vehicle's transmission, allowing for simultaneous interior and exterior cleaning without separate gas engines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If conventional automated cleaning processes are used, then cleaning automation is achieved, but multiple passes are required and many interior areas remain untouched
Solution Approach 1:
The cleaning system divides the bin cleaning into distinct interior and exterior cleaning operations using separate spray rods. The interior spray rod cleans the bin interior while the exterior spray rod cleans the bin exterior, allowing each area to be thoroughly cleaned in a single pass without requiring multiple passes over the same area.
Solution Approach 2:
The system transitions from a single-point cleaning approach to a multi-dimensional cleaning approach by positioning spray rods at different locations (interior and exterior) and orientations. This allows simultaneous cleaning of multiple surfaces from different angles, improving cleaning completeness in a single operation.
2Ease of operation
If rear-mounted cleaning mechanisms are used, then cleaning capability is provided, but the truck cannot navigate narrow roads or alleys
Solution Approach 1:
The cleaning mechanism is repositioned from the rear of the truck to the side of the truck, changing the spatial dimension of operation. This side-mounted configuration allows the truck to access and clean bins in narrow roads and alleys without requiring the truck to back up or maneuver in tight spaces, significantly improving adaptability to various cleaning locations.
3Power
If separate gas engines are used to power water pumps, then pressurized water delivery is achieved, but maintenance requirements and costs increase
Solution Approach 1:
The system merges the power source for the water pumps with the truck's existing engine, eliminating the need for separate gas engines. The truck's engine drives the water pumps through a mechanical drive system, combining multiple functions into a single power source and thereby reducing maintenance requirements, fuel costs, and overall system complexity.
Solution Approach 2:
The truck's engine is utilized for multiple functions: powering the truck itself and simultaneously powering the water pumps for bin cleaning. This multi-functional use of the truck's engine eliminates the need for dedicated separate engines, reducing the number of components that require maintenance and lowering overall operational costs.
4Productivity
If conventional automated cleaning processes are used, then cleaning is performed, but exorbitant amounts of water are consumed
Solution Approach 1:
The system applies water locally and efficiently by using targeted high-pressure spray rods that deliver water precisely where needed on the bin surfaces. This localized water application replaces conventional methods that use excessive amounts of water, reducing water waste while maintaining effective cleaning performance.
