Toilet Assembly Flush Pipe Dosing Device Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing toilet assemblies often require the reservoir for cleaning substances to be located on top of the toilet bowl, which can compromise hygiene and limit flexibility in toilet bowl designs.
Innovation Solution
The toilet assembly features a flush pipe that extends from the water tank to the toilet bowl, with the dosing device mounted directly to the flush pipe, allowing for the introduction of cleaning substances during flushing. This design enables the reservoir to be placed at a higher height, facilitating gravity-fed dosing and improving hygiene.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the reservoir is located on top of the toilet bowl, then the cleaning substance can be easily introduced, but it compromises hygiene and limits flexibility in toilet bowl designs
Solution Approach 1:
The dosing device is moved from the traditional top-mounted position on the toilet bowl to a lateral mounting position on the flush pipe. This spatial repositioning in a different dimension (from vertical top-mounting to horizontal side-mounting) resolves the hygiene issue while maintaining the dosing function.
Solution Approach 2:
The flush pipe serves as an intermediary carrier for the dosing device. Instead of mounting the dosing device directly on the toilet bowl, it is mounted on the flush pipe which connects the water tank to the toilet bowl, allowing indirect integration that improves hygiene and design flexibility.
2Ease of manufacture
If the reservoir is located on top of the toilet bowl, then the cleaning substance can be easily introduced, but it limits flexibility in toilet bowl designs
Solution Approach 1:
By relocating the dosing device from the vertical top surface to the horizontal flush pipe, the invention enables compatibility with various toilet bowl designs including wall-mounted bowls without top openings, thereby increasing design versatility.
Solution Approach 2:
The dosing device mounted on the flush pipe becomes a universal solution that can be integrated with different types of toilet bowls (floor-mounted, wall-mounted, various designs) rather than being limited to specific bowl types with top openings.
3Object-affected harmful factors
If the dosing device is mounted to the flush pipe, then hygiene is improved and design flexibility increases, but the device complexity increases
Solution Approach 1:
The dosing device is designed as a separate, modular component that can be independently mounted to the flush pipe. This segmentation allows for simpler individual components that are easier to manufacture, install, and maintain, offsetting the increased system complexity through modularity.
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 configuration allows for improved hygiene by eliminating the need for a top-mounted reservoir and enabling the use of various toilet bowl designs, while ensuring effective introduction of cleaning substances during flushing.
Implementation Method 1
the reservoir is located at a distance from the dosing device and the dosing device and the reservoir are fluidly connected to each other through a tube. This provides the opportunity to place the reservoir at a higher height level than the dosing device such that the cleaning substance may be introduced into the water flush pipe by gravity

AI summary
A toilet assembly (1) comprises a water tank (5), a toilet bowl (3) which communicates with the water tank (5) through a flush channel, a reservoir (10) for containing a cleaning substance and a dosing device (11) for introducing a cleaning substance from the reservoir (10) into the flush channel. The dosing device (11) and the reservoir (10) are fluidly connected to each other. At least a portion of the flush channel is formed by a flush pipe (8) which extends from a water outlet (9) of the water tank (5) to the toilet bowl (3) where it is mounted to a water inlet of the toilet bowl (3). The dosing device (11) is mounted to the flush pipe (8).
