Flushing Device Valve Arrangement Hygiene
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flushing devices with valve arrangements for urinals, toilets, and bidets face challenges in drinking water hygiene and space efficiency, particularly in avoiding stagnant water and optimizing water flow, with existing designs being complex to assemble and adjust.
Innovation Solution
A flushing device with a valve arrangement where the inflow and outflow channels are aligned straight and parallel, allowing for easy rotation and connection from above or front, featuring a flexible flushing line with an arcuate section guided by a cable, ensuring optimal water flow and hygiene by preventing 'water pocket' formation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the inflow channel and outflow channel are arranged at right angles (prior art design), then the water flow path is extended, but this creates deflection and potential water pocket formation that compromises hygiene
Solution Approach 1:
Instead of arranging channels at right angles as in prior art, the patent inverts the approach by aligning the inflow and outflow channels in a straight line (0° angle), eliminating deflection and water pocket formation while simplifying the overall structure
2Adaptability or versatility
If the valve arrangement is designed for fixed installation orientation, then manufacturing is simplified, but adaptability to different installation scenarios (above or front actuation) is reduced
Solution Approach 1:
The valve arrangement is designed with universal adaptability by providing multiple connection possibilities (above and front actuation) through strategically positioned connection pieces, allowing the same component to serve multiple installation scenarios without requiring separate designs
3Ease of operation
If rigid flushing lines are used, then structural stability is maintained, but height adjustment and installation flexibility are limited
Solution Approach 1:
The patent transitions from rigid to dynamic structures by incorporating flexible flushing lines that can adapt to different heights and positions while maintaining functional integrity, allowing the system to change its configuration based on installation requirements
4Adaptability or versatility
If multiple connection points are added for versatile installation, then adaptability improves, but device complexity increases
Solution Approach 1:
The patent combines multiple connection functions into integrated connection pieces that serve dual purposes (both above and front actuation capabilities), reducing the total number of separate components while maintaining versatile installation options

AI summary
The arrangement (1) has a flushing valve e.g. diaphragm valve, including a valve body with an inflow channel (19) and an outflow channel (20). The inflow channel is attached to a supply line (2), and the outflow channel is attached to a flushing line (3) i.e. flexible pipeline. The channels extend along a common straight line and are arranged in a horizontal plane. The valve is arranged in a fitting cabinet with a front side on which an inspection opening for the valve is arranged. The front side extends in a horizontal or vertical plane.
