Flush Tank Filling Tap With Self-Cleaning Integrated Filter
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Filling devices for flushing tanks in sanitary appliances tend to accumulate deposits, leading to malfunctions, and are difficult to clean, especially when mounted in-wall or embedded, requiring disassembly from the mains water supply.
Innovation Solution
A tap with an integrated filter that allows for cleaning using the mains water flow without disassembly, enabling quick and simple assembly and mounting in various positions, and includes a removable cartridge with operating positions for filtration, cleaning, and manual inspection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an integrated filter is added to the tap, then deposit accumulation is prevented and reliability is improved, but device complexity increases
Solution Approach 1:
The filter is integrated directly into the tap body, combining the filtration function with the tap structure. This prevents deposit accumulation in the filling device while avoiding the need for a separate filter unit, thus improving reliability without excessively increasing complexity.
Solution Approach 2:
The tap is designed to perform multiple functions: water flow control, filtration, and self-cleaning. The integrated filter serves both filtration and easy-cleaning purposes, as the entire tap can be removed and cleaned under running water, reducing maintenance complexity.
2Adaptability or versatility
If the filling device is mounted in-wall or embedded, then adaptability is improved, but ease of operation for cleaning deteriorates
Solution Approach 1:
The tap is designed as a removable, modular component that can be easily detached from the filling device. This segmentation allows the tap to be mounted in various positions (in-wall or embedded) while maintaining easy accessibility for cleaning by simply removing the tap under running water.
Solution Approach 2:
The tap incorporates a dynamic removal mechanism that allows it to be easily detached and reattached. This dynamic design enables flexible mounting positions while ensuring that cleaning remains simple and accessible, as the tap can be quickly removed and cleaned under running water without disassembly.
3Manufacturing precision
If manual cleaning requires disassembly and detachment from mains water, then manufacturing precision is maintained, but loss of time increases
Solution Approach 1:
The tap is designed as a separable component that can be easily removed from the filling device without complex disassembly. This segmentation maintains manufacturing precision through standardized connection interfaces while dramatically reducing cleaning time by allowing the tap to be quickly detached and cleaned under running water.
Solution Approach 2:
The tap is pre-designed with a removable structure that anticipates cleaning needs. The connection interface is prepared in advance to allow easy detachment, so when cleaning is needed, the user can quickly remove and clean the tap under running water without time-consuming disassembly procedures.
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 integrated filter reduces the need for frequent cleaning, prevents deposit accumulation, and facilitates easy maintenance by using the water flow for self-cleaning, ensuring the tap remains functional and easy to maintain.
Implementation Method 1
The tap (1) is equipped with an integrated filter, which makes it possible to reduce, or even eliminate, the need for cleaning the filling device connected to the tap
Implementation Method 2
