Bidet Pump Inversion for Warm Water Supply
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing excrement treatment apparatuses face issues with initial cold water spraying in bidets, residual water leakage during relocation, inefficient drainage of stagnant water, high pump load, and complex filter replacement processes, leading to user discomfort, environmental contamination, and increased operational effort.
Innovation Solution
The apparatus operates pumps in reverse to collect cold water before heating, includes a drainage line for easy water removal, uses dual pumps for increased pressure, and features a simplified filter design with sequential air filtration and automatic UV lamp power blocking for safe replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the pump operates in forward direction only, then washing water is supplied to mounting unit, but cold residual water is sprayed in initial washing operation
Solution Approach 1:
The pump is made to operate in reverse direction to collect cold residual washing water from the supply path before the instantaneous water heater, then operates in forward direction to supply heated water, ensuring warm water is provided from the initial washing operation
2Adaptability or versatility
If connector of connection tubes is separated to replace mounting unit, then mounting unit can be replaced, but residual washing water is poured into floor
Solution Approach 1:
The pump collects all residual washing water in the supply path before the instantaneous water heater into the washing water storage tank before the mounting unit is replaced, preventing water from being poured onto the floor when connection tubes are disconnected
3Reliability
If stagnant washing water is not drained from washing water storage tank, then storage is simple, but bacteria propagation and decomposition occur
Solution Approach 1:
The pump automatically drains stagnant washing water from the washing water storage tank back to the drainage line when the water level reaches a predetermined height, eliminating the need for manual drying operations and preventing bacterial propagation
4Stress or pressure
If one pump is used for washing water supply, then device complexity is low, but gushing pressure is insufficient
Solution Approach 1:
The washing water supply system is divided into two parallel pumps, allowing each pump to operate independently and provide sufficient gushing pressure to the mounting unit, thereby improving washing efficiency without requiring a complex dedicated pump design
5Reliability
If filter unit has complex coupling structure, then filtration is effective, but filter replacement is difficult
Solution Approach 1:
The filter unit is divided into separable components with simplified coupling structures, allowing the filter element to be easily removed and replaced while maintaining effective filtration performance through the modular design
