Straight-column flushing switch with independent manual mode
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional straight-column flushing toilets face challenges with size compatibility issues during replacement or repair, leading to increased costs and difficulties in maintenance, especially when automatic flushing mode fails, affecting the functionality of both automatic and manual flushing modes.
Innovation Solution
A straight-column flushing switch with a sliding module and elastic component that allows for both automatic and manual flushing modes, independent of the water tank's upper cover size, utilizing a support base and special-type gasket for stability and anti-slip functionality, enabling operation under low water pressure and volume conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the straight-column flushing switch is combined with the upper cover of the water tank, then the size of the switch is limited to match the opening size of the upper cover, but this increases the cost and difficulty of replacement or repair
Solution Approach 1:
The flushing switch is separated from the upper cover assembly into an independent component that can be installed separately on the valve assembly. This segmentation allows the switch to be replaced without replacing the entire upper cover, reducing repair costs and complexity while maintaining size adaptability through independent component design.
2Adaptability or versatility
If the pressing component is linked with the straight-column flushing switch, then the opening size matching issue is avoided, but the manual flushing mobile kit operates together with the automatic flushing assembly, causing both modes to fail simultaneously when frequent manual flushing is needed
Solution Approach 1:
The manual flushing and automatic flushing assemblies are separated into independent operational units. The manual flushing mobile kit is designed to operate independently from the automatic flushing assembly, allowing manual flushing to function even when the automatic mode fails. This segmentation ensures reliability by providing independent failure modes.
Solution Approach 2:
A decoupling mechanism or intermediary structure is introduced between the manual flushing pressing component and the automatic flushing assembly. This intermediary allows the manual flushing to be activated independently without necessarily activating the automatic flushing assembly, enabling manual operation even when automatic mode is malfunctioning.
3Ease of operation
If the flushing switch operates under low water pressure and low water volume conditions, then normal flushing function is maintained, but the service life of the flushing switch needs to be extended
Solution Approach 1:
Protective structures such as shock-absorbing materials, cushioning elements, or protective coatings are incorporated into the flushing switch design beforehand. These protective features cushion the impact of low-pressure water flow and reduce wear on critical components, extending the service life while maintaining functionality under low water pressure and volume conditions.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution extends the service life of the flushing switch by reducing the frequency of manual flushing mode usage and maintaining normal operation under low water pressure, while providing anti-slip and anti-loose features on the valve assembly, thus simplifying maintenance and reducing replacement costs.
Implementation Method 1
an elastic component arranged on an outer wall surface of the push rod, the elastic component having one end contacting the base and the other end contacting a bottom surface of the first upper sliding component of the sliding module

AI summary
A straight-column flushing switch and a straight-column flushing toilet are provided. Therein, the straight-column flushing switch includes a body, a base, a sliding module, and a manual flushing module. The sliding module includes a first upper sliding component and a push rod connected to the first upper sliding component. The first upper sliding component movably contacts an inner wall surface of the body. The manual flushing module is positioned on the sliding module. One end of a second upper sliding component abuts against a limiting ring and moves in contact with the inner wall surface of the body. In the automatic flushing mode, the sliding module separates from the manual flushing module, it reduces the frequency of movement of the manual flushing module, thereby extending its lifespan. In cases where the automatic flushing malfunctions, the manual flushing module can effectively perform manual flushing.
