Valve Top Automatic Reset via Control Sleeve
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing upper valve parts do not automatically return to the 'completely closed' position after fluid dispensing, leading to inefficiencies in water usage, particularly when dispensing hot water.
Innovation Solution
An upper valve part design where the control sleeve is connected to the spindle in an axially displaceable manner via a form fit, with a spring prestressing the control sleeve against the headpiece, and featuring sloping guide edges that increase the restoring force when rotated, allowing automatic return to the 'completely closed' position after actuation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the valve body remains in the open position after actuation, then fluid dispensing is maintained, but water usage increases unnecessarily and energy is wasted
Solution Approach 1:
The valve body automatically returns to the closed position without manual intervention. The spring (7) stores potential energy during opening and automatically restores the valve to closed position, making the system self-regulating and eliminating the need for user action to reset the valve.
Solution Approach 2:
The control sleeve (6) with guide edges (64, 171) provides mechanical feedback through the spring mechanism. When the valve opens, the control sleeve rotates and compresses the spring; when actuation stops, the spring expands and automatically returns the valve to closed position, creating a feedback loop that ensures complete closure.
2Loss of substance
If a spring mechanism with control sleeve is added to enable automatic resetting, then water usage is optimized, but device complexity increases
Solution Approach 1:
The control sleeve (6) serves multiple functions: it guides the spindle (2), transmits rotational motion, provides mechanical feedback through guide edges, and acts as a mounting structure for the spring mechanism. This multi-functionality reduces the need for separate components and minimizes overall complexity.
Solution Approach 2:
The control sleeve integrates the spring mounting structure, guide edges for mechanical feedback, and spindle guidance into a single component. The guide edges (64, 171) are formed directly on the control sleeve, merging the feedback mechanism with the control structure itself, thereby simplifying the overall design.

AI summary
The invention relates to a valve top with a head (1) which is centrally penetrated by a spindle (2) which is rotatably mounted in the head (1) about its longitudinal axis and via which a valve body can be actuated, wherein the spindle (2) is provided with a control sleeve (6) which interacts with a control contour (17) arranged on the head (1) in such a way that, after actuation of the valve body via the spindle (2) in a defined direction, an automatic return of the valve body to a basic position is effected.
