Tap Mounting With Isolator Valve Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid delivery devices, such as taps, require complex installation and maintenance processes, including separate connections for hot and cold water supplies and often necessitate disconnecting the water supply to isolate or replace the tap body, which can be cumbersome and inefficient.
Innovation Solution
A fluid delivery device with a detachable body element that uses a push-fit mechanism secured by rotation, allowing the body element to be easily attached and detached from the mounting element without disconnecting from the fluid supply, featuring a clamping assembly for secure mounting and an isolator valve assembly that controls water flow based on the body element's rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the body element is made detachable for easy maintenance and replacement, then the ease of repair is improved, but the reliability of fluid flow control may worsen due to potential leakage at connection points
Solution Approach 1:
The tap is divided into separate body element and mounting element that can be independently replaced. The body element containing the valve mechanism can be detached and replaced without affecting the mounted connection to the fluid supply, enabling easy maintenance while maintaining system reliability through sealed connection interfaces.
Solution Approach 2:
A sealed connection interface acts as an intermediary between the detachable body element and the mounted mounting element. This intermediary connection maintains fluid tightness during detachment and reattachment operations, preventing leakage while allowing easy replacement of the body element.
2Reliability
If separate isolating valves are installed for hot and cold water supplies, then the reliability of fluid isolation is improved, but the device complexity increases
Solution Approach 1:
The isolating valve functionality is merged with the body element itself. The valve mechanism is integrated into the detachable body element, combining the flow control and isolation functions in one component rather than requiring separate isolating valves for hot and cold water supplies.
Solution Approach 2:
The body element serves multiple functions: it acts as both the flow control valve and the isolation mechanism. By making the body element detachable and integrating the valve mechanism, it provides both mixing/flow control and fluid isolation capabilities that would otherwise require separate components.
3Loss of time
If the mounting element remains connected to the fluid supply during body element replacement, then the loss of time is reduced, but the ease of operation worsens due to restricted access for disconnection
Solution Approach 1:
The tap is segmented into a permanently mounted mounting element connected to the fluid supply and a detachable body element. This segmentation allows the body element to be easily detached and replaced from the accessible front side without requiring disconnection of the mounted mounting element or access to hidden connection points.
Solution Approach 2:
The mounting element serves as an intermediary that remains permanently connected to the fluid supply while providing an accessible interface for attaching and detaching the body element. This intermediary structure enables quick replacement operations without affecting the mounted connection to the water supply.

AI summary
A fluid delivery device comprises a mounting element (5) for connection to a fluid supply (7, 9) and a body element (3) mounted on the mounting element (5) for controlling discharge of fluid from the device. The body element (3) is detachable from the mounting element (5) without disconnecting the mounting element (5) from the fluid supply (7, 9). The mounting element (5) includes an isolator valve assembly having an open position to connect the fluid supply (7, 9) to the body element (3) when the body element (3) is mounted on the mounting element (5) and a closed position to isolate the fluid supply (7, 9) when the body element (3) is removed from the mounting element (5), wherein the isolator valve assembly moves between the open and closed positions as the body element (3) is attached to and detached from the mounting element (5).
