External Cleaning Assembly for Internal Flow Path Sterilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional human body part washing devices face challenges in efficiently sterilizing and descaling their internal flow paths due to the inability to circulate sterilization or descaling liquids effectively within these paths.
Innovation Solution
A new-type cleaning device and method that includes a movable cleaning assembly outside the washing assembly, utilizing a water pump and intermediate device to circulate cleaning liquid through the internal flow path, allowing for thorough and efficient cleaning without occupying internal space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a sterilization component is arranged in the internal flow path to sterilize the internal flow path, then the sterilization function is improved, but the device complexity increases and the component cannot be removed from the washing device
Solution Approach 1:
The cleaning assembly is extracted from the internal flow path and positioned externally. The water pump circulates cleaning liquid from the external cleaning assembly through the internal flow path, enabling sterilization without permanently installing components inside the flow path. This resolves the contradiction by maintaining sterilization function while reducing device complexity and enabling removable cleaning components.
Solution Approach 2:
The water pump acts as an intermediary device that transfers cleaning liquid from the external cleaning assembly through the internal flow path. This mediator enables the cleaning function without requiring the cleaning assembly to be permanently integrated into the flow path, thus reducing device complexity while maintaining sterilization effectiveness.
2Reliability
If a sterilization component is arranged in the internal flow path, then the sterilization function is improved, but the sterilization liquid cannot circulate efficiently and is wasted
Solution Approach 1:
The water pump creates a continuous circulation system where cleaning liquid flows from the external cleaning assembly through the internal flow path and returns to the cleaning assembly. This continuous circulation ensures the sterilization liquid is reused repeatedly, preventing waste and improving sterilization effectiveness through multiple passes.
Solution Approach 2:
The circulation system recovers the cleaning liquid after it passes through the internal flow path, returning it to the cleaning assembly for reuse. This recovery mechanism prevents the loss of expensive sterilization liquid and maintains efficient sterilization function over extended periods.
3Reliability
If an electrolytic cell is provided in the flow channel to produce sterilizing water, then the sterilization function is improved, but the device complexity increases
Solution Approach 1:
The electrolytic cell functionality is extracted from the internal flow path and replaced by an external cleaning assembly containing pre-prepared sterilizing solution. The water pump circulates this external solution through the flow path, achieving sterilization without installing complex electrolytic equipment inside the washing device, thus reducing device complexity.
4Device complexity
If the cleaning assembly is arranged outside the washing assembly, then the device complexity is reduced and operational flexibility is improved, but the cleaning effectiveness may be compromised
Solution Approach 1:
The water pump serves as an intermediary that bridges the external cleaning assembly and the internal flow path, ensuring effective delivery of cleaning liquid despite the external positioning. This mediator maintains cleaning effectiveness by providing sufficient flow pressure and circulation while allowing the cleaning assembly to remain external, thus reducing device complexity.
Solution Approach 2:
The continuous circulation of cleaning liquid from the external cleaning assembly through the internal flow path and back ensures sustained cleaning effectiveness. The repeated circulation passes allow thorough cleaning without requiring the cleaning assembly to be internally positioned, maintaining effectiveness while reducing device complexity.
