Valve Fitting with Integral Stop Valves for Leakage Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional shower valve fittings lack efficient control mechanisms for managing hot and cold water flow, leading to inefficiencies in distributing water between tub spouts and shower heads, and often require complex installations that can be prone to leakage.
Innovation Solution
A valve fitting with integral stop valves and actuators that control fluid flow through angularly offset receiving bores, utilizing a plaster guard for secure mounting and easy access to stop actuators, allowing for precise control of water flow between open and closed positions, thereby preventing leaks and improving distribution efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional valve fittings are used without integral stop valves, then the installation is simpler, but control over water flow distribution is inefficient and leakage is more prone
Solution Approach 1:
The patent combines the stop valve functionality directly into the valve fitting body by providing receiving bores and actuators that are integral parts of the fitting. This merging of functions eliminates the need for separate stop valve components while achieving reliable water flow control and leakage prevention at multiple points in the distribution system.
Solution Approach 2:
The valve fitting is designed to perform multiple functions: it serves as both the main water distribution point and incorporates stop valves for controlling flow to individual outlets. The integral actuators provide both aesthetic coverage (plaster guards) and functional control (stop valve operation) within a single integrated structure.
2Ease of operation
If stop actuators are positioned for easy access, then operation is more convenient, but the mounting structure becomes more complex
Solution Approach 1:
The patent positions the actuator input ends within the plane of the outer surface of the plaster guard, effectively moving the control interface to a convenient accessible dimension. The plaster guard itself serves as the mounting structure that provides both structural support and aesthetic coverage, eliminating the need for additional mounting brackets or complex positioning mechanisms.
3Adaptability or versatility
If multiple inlets and outlets are provided for comprehensive water distribution, then functionality is enhanced, but control and leakage management become more difficult
Solution Approach 1:
The patent segments the water distribution system by providing separate receiving bores for hot and cold water supplies, and separate outlets for shower and tub connections. Each segment has its own integral stop valve actuator, allowing independent control of water flow to different destinations while maintaining a unified valve fitting structure.
