Removable Wall Element for Rimless Toilet Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Toilets and urinals with flushing rims face difficulties in cleaning the areas around the flushing rim and rear sections due to dirt accumulation, which is challenging with conventional cleaning methods, especially in institutional settings where hygiene is paramount.
Innovation Solution
A removable wall element designed to fit within the toilet bowl, allowing for easy access and cleaning of the areas where flushing water flows through, preventing soiling and maintaining the flow profile without the need for direct attachment to the ceramic bowl.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rim is provided on the toilet bowl for flushing water to spill, then the flushing function is improved, but cleaning of the rim and rear areas becomes difficult due to dirt accumulation
Solution Approach 1:
The toilet bowl is divided into separate functional areas: a rimless design separates the flushing water flow path from the seating area, allowing the rear wall section to be independently accessible for cleaning while maintaining the flushing function through side wall openings
Solution Approach 2:
The traditional rim structure is completely removed from the toilet bowl design. Instead of having a rim that traps dirt, the flushing water is directed to strike the rear wall and flow down the inner surface, extracting the rim function while eliminating its cleaning problems
2Ease of operation
If cleaning agents are attached to the flushing water flow profile in rimless toilets, then routine cleaning is improved, but the flow profile is disrupted and proper rinsing is prevented
Solution Approach 1:
A separate cleaning agent container is introduced as an intermediary component that does not interfere with the flushing water flow. The container is positioned to allow cleaning agents to be applied to the bowl surface without obstructing the water jets or disrupting the flow profile necessary for proper rinsing
3Ease of operation
If manual cleaning of outlet openings and crevices is performed, then soiling removal is attempted, but the process is unhygienic and does not achieve desired results
Solution Approach 1:
The toilet bowl design enables self-cleaning through the flushing water flow that naturally wets and flushes away dirt from the inner surface. The rear wall section is designed to be wetted by the flushing water, allowing the system to clean itself without requiring manual intervention in difficult-to-reach areas
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
Facilitates easy and hygienic cleaning of the toilet bowl, preventing clogging and maintaining the flow profile, making it suitable for institutional use by allowing the wall element to be removed and cleaned separately.
Implementation Method 1
the rinsing water, through its impact on the wall section, the shape of the guide elements, and the shape of the bowl's inner wall, completely wets the inner surface of the bowl to be cleaned
Implementation Method 2
The cleaning agents gradually dissolve in the cistern over a multitude of flushing cycles, thus providing flushing water containing cleaning and/or fragrance agents
