Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current filling limiting devices for sanitary facilities are unreliable, prone to clogging, aesthetically unpleasing, and require complex production due to exposed openings that can be tampered with and clogged by floating elements or sediment.
Innovation Solution
A concealed filling limiting device with a pipe system and vent control valve, utilizing a membrane and magnetic plug mechanism to control water flow, preventing clogging and ensuring reliability and ease of production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If openings are made on the wall of the filling tank at the maximum filling level, then the filling level can be limited, but the tank becomes weaker and more prone to clogging
Solution Approach 1:
The invention extracts the filling level control function from the tank wall itself by introducing a separate pipe system that connects to the tank. The pipe extends to the maximum filling level and provides an overflow path, eliminating the need to create openings in the tank wall. This preserves the structural integrity and strength of the tank while achieving the same filling limitation function.
Solution Approach 2:
The pipe system acts as an intermediary element between the filling tank and the drainage system. Instead of directly opening the tank wall, the pipe mediates the water flow at the maximum filling level, providing a controlled overflow path that maintains tank strength while ensuring reliable filling level control.
2Reliability
If openings are made on the tank wall, then filling can be limited, but the openings are exposed to clogging by floating elements and sediment
Solution Approach 1:
The invention removes the opening from the tank wall environment and relocates the filling control function to a pipe system that is inaccessible to floating elements and sediment. The pipe extends vertically to the maximum filling level and connects to the drainage system, creating a clog-resistant overflow path that is protected from contaminants in the water.
Solution Approach 2:
The invention changes the spatial arrangement by extending the pipe vertically to reach the maximum filling level, rather than creating a horizontal opening in the tank wall. This vertical configuration, combined with the pipe's connection to the drainage system, creates a dimensionally separated overflow path that is less susceptible to clogging by floating elements and sediment.
3Reliability
If openings are made on the tank wall, then filling can be limited, but the openings are accessible to users and subject to intentional tampering
Solution Approach 1:
The invention extracts the filling control function from the accessible tank wall surface and relocates it to an inaccessible pipe system. The pipe extends vertically and connects to the drainage system in a location that is not easily accessible to users, thereby preventing intentional tampering while maintaining the filling level limitation function.
4Reliability
If openings are made on the tank wall, then filling can be limited, but production becomes more complex and costly
Solution Approach 1:
The invention removes the complex requirement of creating precise openings in the tank wall and replaces it with a simpler pipe system. The pipe can be easily manufactured and installed, connecting to the tank at the base and extending to the maximum filling level, thereby simplifying production while achieving reliable filling control.
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
The device provides long-term reliability, prevents clogging, and simplifies production while maintaining strength and aesthetics by concealing the vent control valve and using a magnetic plug system to manage water flow without exposed openings.
