Hybrid Distribution Valve for Dual-Source Toilet Flushing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing toilet flushing systems rely solely on water pump pressurization, which consumes a lot of power and cannot function during power outages, and single water inlet distribution valves are inefficient due to unstable tap water pressure, affecting flushing performance.
Innovation Solution
A hybrid distribution valve with a water path distribution module and pressure water inlet module, featuring switching mechanisms and channels for both tap water and water pump connections, allowing seamless switching between modes to adapt to different scenarios.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If water pump pressurization is used for flushing, then flushing effect is improved, but power consumption increases and the system cannot function during power outages
Solution Approach 1:
The distribution valve is designed with dual water inlet capabilities: it can receive pressurized water from the water pump through the first water inlet channel, or receive tap water directly through the second water inlet channel. The switching mechanisms enable the valve to automatically or manually select the appropriate water source, making the flushing system universally adaptable to different operating conditions (powered and unpowered scenarios) without requiring separate systems for each mode.
2Reliability
If a water inlet valve group with closed water tank is added to solve power outage issues, then flushing availability during power outages is improved, but device complexity and cost increase
Solution Approach 1:
The patent merges the functions of the water inlet valve group and the distribution valve into a single integrated distribution valve structure. The switching mechanisms (first and second switching mechanisms) are integrated within the distribution valve body, allowing the valve to perform both water source selection and distribution functions simultaneously. This eliminates the need for a separate closed water tank and water inlet valve group, reducing system complexity while maintaining the ability to flush during power outages by using tap water directly.
3Use of energy by moving object
If the distribution valve is connected to tap water pipeline, then energy saving is improved, but flushing performance deteriorates due to unstable tap water pressure
Solution Approach 1:
The distribution valve incorporates dynamic switching capabilities that allow it to adapt to changing water pressure conditions. The switching mechanisms can respond to pressure variations in the tap water supply and automatically or manually switch between tap water mode (second water inlet channel) and water pump pressurization mode (first water inlet channel). This dynamic adaptability ensures optimal flushing performance regardless of tap water pressure stability, while maximizing energy efficiency by preferring tap water when available and pressure conditions are adequate.
