Removable Bidet Shower Arm with Sealed Coupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Shower toilets with non-removable shower arms face challenges in hygiene maintenance, as users need to access and clean the entire length of the shower arm protruding into the toilet bowl, which is prone to soiling and calcification, affecting cleanliness and appearance over time.
Innovation Solution
A shower toilet design with a removable shower arm part that features a coupling with transverse line transitions, offset and sealed by sealing rings, allowing for easy removal and cleaning, including the option to detach the front part with the shower nozzle for frequent cleaning and replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the shower arm is made non-removable to simplify the structure, then the device complexity is reduced, but the ease of cleaning deteriorates because users cannot access the entire shower arm for cleaning
Solution Approach 1:
The shower arm is divided into two separable parts: a first shower arm part that remains in the toilet body and a second shower arm part that can be removed. This segmentation allows users to access and clean the entire shower arm by simply detaching the second part, resolving the contradiction between structural simplicity and cleaning accessibility.
Solution Approach 2:
The second shower arm part is designed to be extractable from the first shower arm part through a coupling mechanism. This extraction capability enables users to remove the shower arm portion that protrudes into the toilet bowl for thorough cleaning, maintaining ease of operation while preserving structural simplicity.
2Ease of operation
If the shower arm is made removable to improve cleaning accessibility, then the ease of cleaning is improved, but the device complexity increases due to the coupling mechanism with sealing rings
Solution Approach 1:
The shower arm is segmented into removable and fixed portions connected by a coupling mechanism. This segmentation enables easy removal for cleaning while the coupling structure with sealing rings ensures proper connection and sealing, balancing accessibility with controlled complexity.
Solution Approach 2:
The coupling mechanism acts as an intermediary between the first and second shower arm parts, providing a standardized interface for attachment and detachment. The sealing rings serve as intermediaries to ensure proper sealing during connection, simplifying the overall design while enabling removable functionality.
3Productivity
If the shower arm protrudes further into the toilet bowl to improve showering function, then the showering performance is improved, but the object-generated harmful factors increase due to greater exposure to soiling and calcification
Solution Approach 1:
The shower arm is segmented into a fixed portion and a removable portion. This allows the shower arm to protrude sufficiently into the toilet bowl for effective showering while enabling easy removal for cleaning, thereby reducing soiling and calcification accumulation on the exposed surfaces.
Solution Approach 2:
The second shower arm part can be detached and cleaned separately, allowing users to remove and clean the portion most prone to soiling. This discarding and recovering approach enables maintenance of hygiene standards while maintaining the protruding configuration for optimal showering function.

AI summary
The WC comprises multiple movable shower arms (6,11,14) that are mounted in a lavatory housing of a toilet bowl or projected into the toilet bowl. The shower arms are removed by an operation of the toilet bowl. The shower arms include a coupling (13) that comprises multiple line transitions which are oriented transverse to a longitudinal direction of the shower arm. The line transitions of the shower arm are separated and sealed with multiple sealing rings by pressing by a mounting movement of the shower arm. An independent claim is included for a method for cleaning a shower-type WC.
