Existing cleaning devices for containers with human waste require increased equipment and construction volume to incorporate both low-pressure and high-pressure cleaning systems, leading to higher production costs and complexity.
Innovation Solution
A cleaning device with a multi-stage pump system that includes both low-pressure and high-pressure stages, where the cleaning fluid is routed through a bypass to the nozzle system, allowing for efficient switching between low-pressure and high-pressure modes using a single nozzle system, reducing the need for multiple nozzles and components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If both low-pressure and high-pressure cleaning systems are incorporated into the cleaning device, then cleaning performance is improved, but device complexity and construction volume increase
Solution Approach 1:
The patent combines both low-pressure and high-pressure cleaning systems into a single integrated cleaning device. The device includes a pump system that can operate in both low-pressure and high-pressure modes, and a nozzle system that can handle both pressure ranges. This merging eliminates the need for separate cleaning devices for different pressure requirements, reducing overall equipment expenditure while maintaining comprehensive cleaning performance for various soiling levels.
Solution Approach 2:
The cleaning device is designed with universal functionality to perform both low-pressure cleaning (for initial soiling removal) and high-pressure cleaning (for heavy soiling) using a single device. The pump system can switch between operating modes, and the nozzle system is configured to effectively deliver cleaning fluid at both pressure levels, making the device adaptable to different cleaning scenarios without requiring multiple specialized devices.
2Productivity
If a high-pressure cleaning system is added to the cleaning device, then removal rate for heavy soiling is improved, but construction volume and production costs increase
Solution Approach 1:
The patent integrates the high-pressure cleaning capability into the existing low-pressure cleaning device structure. The pump system is designed with both low-pressure and high-pressure stages, and the nozzle system is configured to effectively deliver cleaning fluid at both pressure levels. This integration allows the device to achieve high removal rate for heavy soiling without requiring a completely separate high-pressure cleaning system, thereby minimizing construction volume increases.
3Productivity
If multiple nozzle systems are used for low-pressure and high-pressure cleaning, then cleaning effectiveness is improved, but device complexity increases
Solution Approach 1:
The nozzle system is designed with universal functionality to effectively deliver cleaning fluid at both low-pressure and high-pressure modes. The nozzles are configured with specific geometries and arrangements that allow them to perform optimally across a range of pressure levels, eliminating the need for separate nozzle systems for low-pressure and high-pressure cleaning. This reduces the number of components and simplifies the overall device structure while maintaining cleaning effectiveness.
