Modular Bidet Attachment: Rotating Snap-Fit Mounts for Easy Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bidets face issues such as grime accumulation in mounting disc openings, difficulty in cleaning the toilet bowl due to secure fixation, accidental water activation, and interference between the bidet sprayer nozzle and toilet seat due to varying toilet bowl shapes.
Innovation Solution
A modular bidet attachment with snap-fit mounting discs, a rotating chassis design, a lever handle with automatic shut-off, and a 105-degree angled sprayer nozzle to address these issues, enhancing cleanliness, ease of installation and removal, and compatibility with various toilet designs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the bidet is securely fixed in place, then the bidet provides stable and reliable operation, but it becomes very difficult to clean the toilet bowl and access certain areas of the toilet
Solution Approach 1:
The bidet attachment is divided into modular components including a removable bidet body, separate mounting disc, and detachable sprayer assembly. This segmentation allows the bidet to be securely mounted during operation but easily removed for cleaning, resolving the contradiction between stability and cleaning accessibility.
Solution Approach 2:
The mounting system transitions from a static secure fixation to a dynamic removable connection. The mounting disc with opening allows the bidet to be firmly attached during use but easily detached when cleaning is needed, providing adaptability between operational stability and maintenance accessibility.
2Object-generated harmful factors
If the sprayer nozzle hangs at a 90 degree angle into the bowl, then the water spraying function is achieved, but it interferes with the toilet seat due to varying bowl shapes
Solution Approach 1:
The sprayer assembly is designed with adjustable positioning capabilities, allowing the nozzle angle and position to be modified to accommodate different toilet bowl shapes. This dynamic adjustment ensures proper water spraying function while adapting to various toilet designs, eliminating interference with the toilet seat.
Solution Approach 2:
The sprayer nozzle parameters including angle and position can be changed to optimize performance for different toilet configurations. By adjusting these parameters, the system maintains effective water spraying while avoiding interference with the toilet seat across various bowl shapes.
3Ease of manufacture
If the mounting disc opening is large enough for easy installation, then installation is simplified, but grime accumulates in the opening over time
Solution Approach 1:
The mounting disc opening is minimized or eliminated by using an external mounting mechanism that attaches to the toilet bowl edge rather than requiring a large opening in the disc. This extraction of the opening function reduces grime accumulation while maintaining installation ease through the external mounting interface.
Solution Approach 2:
The mounting disc design incorporates localized features such as small precision openings or alternative mounting interfaces that prioritize cleanliness. By concentrating the mounting function in specific localized areas rather than requiring large openings, the design reduces grime accumulation while maintaining installation simplicity.
4Ease of operation
If the water valve lever is easily operable, then user activation is convenient, but water can be accidentally turned on by children or bumping
Solution Approach 1:
The water valve lever incorporates an automatic shut-off mechanism that preliminarily prepares to close the water flow after a set duration. This preliminary action ensures that even if the lever is accidentally activated by children or bumped, the water flow will automatically stop after a predetermined time, preventing accidents.
Solution Approach 2:
The water valve system includes feedback mechanisms such as timers or sensors that monitor the activation state and automatically shut off water flow after a set period. This feedback loop provides both user convenience for activation while preventing accidental continuous operation by children or bumping.

AI summary
A modular bidet attachment. The modular bidet attachment includes mounting discs that mount to a bidet chassis via a snap fit mechanism. The mounting discs include openings that are less than half the length of the diameter of the mounting discs. The mounting discs are configured to rotate after being mounted to the chassis.
