Built-in Solid Hygiene Holder for Urinal Bowl
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sanitary ware systems, particularly in public urinals, face issues with unsightly and easily damaged liquid hygiene chemical containers, space inefficiency, rapid chemical consumption, and the need for protective equipment, which compromise hygiene and aesthetics.
Innovation Solution
A sanitary basin with a built-in holder for solid hygiene products, where the product mixes with flushing water through hidden drain lines, ensuring efficient distribution and visibility of stock levels without external installation or moving parts, maintaining a clean and elegant appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If liquid hygiene chemicals are stored in containers and hung on the urinal, then hygiene function is provided, but the appearance becomes unsightly and the containers are easily damaged or stolen
Solution Approach 1:
The patent extracts the hygiene product storage function from external containers and integrates it into the urinal bowl structure itself. The holder is built into the bowl, removing the need for separate hanging containers, thus maintaining appearance while preserving hygiene function.
Solution Approach 2:
The patent merges the storage function with the urinal bowl structure by integrating the holder directly into the ceramic body. This combination eliminates the visual clutter of external containers while ensuring the hygiene function remains reliable and accessible.
2Reliability
If liquid hygiene chemicals are used, then hygiene function is achieved, but more space is required for bulk storage and chemicals are consumed quickly
Solution Approach 1:
The patent changes the physical state of the hygiene product from liquid to solid tablets. This parameter change allows for more compact storage with higher density, reducing the volume required for bulk storage while maintaining effective hygiene function through controlled dissolution in water.
3Reliability
If liquid hygiene chemicals are used, then hygiene function is provided, but protective clothing and replenishment equipment such as syringes are required
Solution Approach 1:
The patent employs disposable solid hygiene tablets that are simple to replace. Unlike liquid chemicals requiring syringes and protective gear, the solid tablets can be easily inserted into the holder without special equipment, significantly reducing device complexity and safety requirements for maintenance.
4Shape
If a dispenser for hygiene products is built into the urinal, then appearance is improved and no external installation is needed, but the structure becomes more complex
Solution Approach 1:
The patent segments the holder into modular components that can be independently manufactured and assembled. The holder consists of a recess portion integrated into the bowl and a separate cover portion, allowing for simplified manufacturing processes while achieving the desired integrated appearance without excessive structural complexity.
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 solution provides easy access to hygiene products, eliminates the need for protective equipment, ensures continuous hygiene without unsightly external containers, and allows for electronic stock monitoring, enhancing both hygiene and aesthetics in sanitary facilities.
Implementation Method 1
a solid hygiene product (which will dissolve in water) is received in the holder
Implementation Method 2
the one or more drain lines extend between the mixing chamber and the substantially vertical surface portion

AI summary
The basin i.e. urinal basin (102), has a mixing arrangement (114) arranged above or in an upper part of a bowl (104). The mixing arrangement includes an inlet pipe (118) that is connected to a mixing chamber (116) to supply liquid i.e. flushing water, to the mixing chamber. A metal holder (126) holds a hygiene product i.e. solid hygiene product, such that a section of the holder is arranged within the mixing chamber to mix the hygiene product with the liquid in the mixing chamber during utilization. Drain pipes (120) extend between the mixing chamber and the bowl.
