Toilet Flushing Device Actuation Assembly Horizontal Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional toilet flushing systems require difficult maintenance of the sealing gasket due to the need to remove the entire flushing mechanism, which is cumbersome in concealed or narrow cisterns, leading to issues with access and space constraints.
Innovation Solution
A toilet flushing device with a vertically mounted actuation assembly that allows for easy maintenance by enabling the actuation assembly to be disassembled and removed through a simple horizontal translational movement via a vertical light in the housing, using a removable first actuating rod with blocking means to prevent unintended extension during operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the entire flushing mechanism is removed to access the sealing gasket, then the gasket can be replaced, but the operation becomes difficult in concealed or narrow cisterns due to space constraints
Solution Approach 1:
The flushing mechanism is divided into separate components: the housing remains fixed in the cistern, while the actuation assembly (containing the valve and sealing gasket) can be independently removed. This segmentation allows maintenance of the sealing gasket without removing the entire flushing mechanism, solving the space constraint problem in concealed or narrow cisterns
Solution Approach 2:
The actuation assembly is extracted as a removable component from the housing. The vertical light in the housing peripheral wall provides an extraction path, allowing the actuation assembly to be removed horizontally through the light without disturbing the housing's position in the cistern, enabling easy access to the sealing gasket
2Ease of repair
If the actuation assembly is made removable through a vertical light, then maintenance becomes easier, but the housing structure becomes more complex
Solution Approach 1:
The vertical light extends through the entire height of the housing peripheral wall, creating a vertical extraction path. This dimensional feature allows the actuation assembly to be removed horizontally through the light, adding a maintenance access dimension without significantly complicating the housing structure

AI summary
The invention relates to a water flush device (10) comprising a housing (20) and an actuating rod (51) fitted with a flapper (53) in its lower portion. In the configuration of use, the rod is joined to the housing and projects from an upper opening (33) and a lower opening, and is vertically movable between a closed position in which the flapper closes off the discharge opening (7) in the cistern (1), and a discharge position in which the flapper is located above the discharge opening. A vertical aperture (30) extends up the entire height of the housing and is in communication with the upper and lower openings. The aperture is configured so that the rod can be removed from the housing by way of a horizontal translational movement via the aperture.
