Rotating Container Flushing Device for Toilet Bowl Leak Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flushing devices for toilet bowls are prone to water leaks due to lime scale and particle interference with the seal or valve mechanism, leading to costly and hard-to-detect issues.
Innovation Solution
A flushing device with a rotating container in the tank, where the operating handle is offset from the axis of rotation, allowing for leverage control of water evacuation, and a flared bottom for efficient waste detachment, eliminating the need for seals or valves between the tank and bowl.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a seal or valve mechanism is used to close the flushing pipe opening, then the flushing device can control water flow, but it becomes prone to water leaks due to limescale and particle interference
Solution Approach 1:
The patent removes the seal and valve mechanism from the flushing pipe opening, eliminating the components that are susceptible to limescale and particle interference. The flushing pipe remains open without any closing elements, and water flow control is achieved through the rotating container mechanism instead.
Solution Approach 2:
Instead of using a closing mechanism (valve or seal) to control water flow, the invention inverts the approach by using an opening mechanism - a rotating container that can be filled with water and then discharged. The control is achieved by preventing water discharge rather than allowing it and then closing it.
2Ease of operation
If an operating handle is mounted at the axis of rotation, then the mechanism is simpler, but it provides poor leverage control for water evacuation
Solution Approach 1:
The operating handle is deliberately positioned asymmetrically relative to the rotation axis, specifically at a distance from the axis. This asymmetric positioning creates a longer moment arm that provides better mechanical leverage for rotating the container, making it easier to operate despite the slightly more complex mounting structure.
3Productivity
If a flat-bottomed tank is used, then the structure is simpler, but water is poured out at low speed with little training effect on waste
Solution Approach 1:
The tank bottom is designed with a curved, flared shape instead of a flat surface. This curvature concentrates the water flow and increases its velocity as it exits, creating a more effective flushing action that efficiently evacuates waste from the bowl.
4Ease of operation
If a groove of sufficient length is provided in the tank wall, then the container can rotate through a variable angle for water control, but the handle may interfere with user space when seated
Solution Approach 1:
The groove is positioned in the vertical wall of the tank rather than extending horizontally into the user space. This spatial repositioning in another dimension allows the handle to operate vertically or along the wall surface, providing water quantity control through rotation while avoiding interference with the horizontal user space when seated.
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
This design provides better control over water quantity, reduces leaks, and enhances waste evacuation efficiency while avoiding damage to mechanical systems like crank rods or rack pinions, promoting water savings and user-friendly operation.
Implementation Method 1
The maneuvering handle being thus off-centered from the axis of rotation of the container, it makes it possible to act with a leverage effect on the rotation of the container
Implementation Method 2
the bottom of the tank can advantageously be flared at least on the side of the fallout intended to conduct this fallout of water facing the part of the bowl to be cleaned
