Valve Unit Inner Channel Sanitary Water Leakage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional systems for delivering cold, hot, and mixed water with optional carbonation require complex and time-consuming installations, leading to increased costs and safety risks due to potential water leakages from numerous connections.
Innovation Solution
A valve unit with an inner supplying channel directly connects the filtering unit to the sanitary water inlet, eliminating the need for upstream branch pipes and simplifying the connection process, allowing for quicker and safer assembly by an unskilled operator.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional systems use upstream T-shaped pipe-fittings and ball valves for connecting filtering unit to water supply network, then the system can deliver purified water with optional carbonation, but the installation time increases and water leakage risks increase due to numerous connections
Solution Approach 1:
The patent merges the filtering unit directly with the valve unit by integrating the filtered water outlet channel within the valve unit body. This eliminates the need for separate T-shaped pipe-fittings and ball valves, reducing the number of connections from multiple external joints to a single integrated structure, thereby reducing installation time and eliminating leakage risks at connection points.
Solution Approach 2:
The valve unit is designed to perform multiple functions: it controls both sanitary water flow and purified water flow, integrates the filtering unit connection, and provides mixing capabilities. This multi-functionality eliminates the need for separate dedicated components for filtering unit connection and control, simplifying the overall system and reducing installation complexity.
2Ease of manufacture
If conventional systems use multiple separate components (T-shaped pipe-fittings, ball valves, mixer-delivery unit, filtering unit), then the system can provide selective delivery of cold, hot, and mixed water with purification, but the installation cost increases and operator skill requirements increase
Solution Approach 1:
The patent combines multiple separate components (filtering unit, valve unit, mixing mechanism) into a single integrated valve unit structure. The filtering unit is directly connected to the valve unit body through an integrated outlet channel, eliminating the need for separate T-shaped pipe-fittings and ball valves. This reduces device complexity and makes installation simpler and more accessible to unskilled operators.
Solution Approach 2:
While integrating components, the patent maintains functional segmentation within the valve unit body through internally defined channels and cavities. The valve unit body contains distinct regions for sanitary water inlet, hot water inlet, filtered water outlet, and mixing chamber, allowing each function to remain independent while being physically integrated, thus simplifying installation without compromising functionality.

AI summary
The system comprises a valve unit connected to a filtering unit for the selective delivery of cold, hot and mixed sanitary water, respectively either refrigerated or boiling purified water with optional carbonation. The valve unit comprises a base body for housing a first mixer tap, of the cartridge type, which is connected to a first delivery duct of the sanitary water, as well as a second control tap for the purified water, connected to a second delivery duct internal to the previous one. The outlet or each outlet of the purified water of the filtering unit is connected to an inlet of the second control tap, whereas the inlet of the cold water of the filtering unit is directly connected to the inlet of the cold water of the first mixer tap, by means of a branched channel that is provided inside the base body of the valve unit.
