Flush-Mounted Valve Knob Coupling for Readable Control Labels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flush-mounted valves for sanitary fittings face issues with control knobs that can no longer be read when rotated, requiring additional components for rotational fixation, which increases space requirements and risks detachment.
Innovation Solution
A valve design featuring a rotatable flow control element and a valve knob with a rotary coupling that secures the control knob non-rotatably to the valve housing, eliminating the need for additional space-consuming components and preventing unintentional detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the control knob is made rotatable for adjusting flow volume, then the valve operation is improved, but the control knob label becomes unreadable when rotated
Solution Approach 1:
The control mechanism is segmented into two independent rotational elements: the control knob for opening/closing the valve and the flow control element for adjusting flow volume. This segmentation allows each element to perform its function without interfering with the readability of the other, resolving the contradiction between operational ease and information retention.
2Loss of information
If additional components are added to prevent control knob rotation, then the control knob remains readable, but the valve requires more space
Solution Approach 1:
The patent merges the control knob and flow control element into a single integrated assembly where the control knob is non-rotatably connected to the valve body while the flow control element handles flow adjustment. This merging eliminates the need for additional separate components to prevent rotation, thereby reducing space requirements while maintaining label readability.
3Ease of manufacture
If the control knob is made detachable for ease of assembly, then the manufacturing process is simplified, but the control knob may become unintentionally detached
Solution Approach 1:
The control knob is pre-connected to the valve body through a non-rotatable connection during manufacturing, ensuring it remains securely attached during operation. This preliminary action of establishing a secure connection prevents unintentional detachment while maintaining ease of assembly through the simplified connection mechanism.

AI summary
A valve for a flush-mounted body of a sanitary fitting, at least having a valve housing with a longitudinal axis, a rotatable flow control element for adjusting a flow volume of a liquid flowing through the valve, and a valve knob for opening and closing the valve. The valve knob can be adjusted via the flow control element, rotationally and parallel to the longitudinal axis, by a control knob for the valve, and the control knob is fastened to the valve knob by a rotary coupling so that the control knob can be non-rotatably fastened relative to the valve housing.
