Sanitary Valve Upper Part With Slide Handle for Compact Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing valve upper parts require a sufficient spindle length for arcuate movement of the handle, leading to an unobtrusive and compact arrangement that is perceived as optically disruptive due to the handle's distance from the fitting.
Innovation Solution
A valve upper part design where the gripping part is configured as a slide with a pivot space, allowing translational movement of the spindle, enabling arcuate movement within the slide's pivot space without involving the slide in the arcuate movement, and utilizing a driver axle guided through an oblong hole for force transfer, along with a spring element for biasing and a motion link for secure connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the spindle is made long enough to allow arcuate movement of the handle, then the handle can be positioned at a sufficient distance from the fitting for proper operation, but the arrangement becomes optically disruptive and loses compactness
Solution Approach 1:
The invention divides the movement function into two independent components: the slide provides translational movement for force transfer, while the pivot space accommodates the arcuate movement of the spindle end. This segmentation allows each component to be optimized independently, enabling compact overall design while maintaining full operational capability.
Solution Approach 2:
The invention transitions from a single-dimensional rotational movement (traditional arcuate handle movement) to a two-dimensional movement combination: translational movement of the slide along the spindle axis plus arcuate movement within the pivot space. This dimensional change enables the handle to be positioned close to the fitting while still achieving the necessary movement range for operation.
2Shape
If the spindle length is reduced for a compact design, then the arrangement becomes more aesthetically pleasing and less disruptive, but the handle cannot achieve sufficient arcuate movement for proper operation
Solution Approach 1:
The slide acts as an intermediary mechanism that converts translational movement into force transfer to the spindle, enabling arcuate movement without requiring a long spindle. The driver connected to the slide transfers force through the oblong hole, mediating between the linear slide movement and the rotational spindle movement, thus allowing compact design while maintaining operational capability.
Solution Approach 2:
The invention makes the movement mechanism dynamic by allowing the slide to translate along the spindle axis while simultaneously accommodating the arcuate movement of the spindle end within the pivot space. This dynamic configuration enables the system to adapt its movement pattern based on operational requirements, achieving both compactness and full range of motion.
3Ease of manufacture
If a traditional rotating spindle mechanism is used, then the structure is simple and easy to manufacture, but the handle must be positioned at a distance that creates an unobtrusive and compact arrangement perceived as optically disruptive
Solution Approach 1:
The invention merges two movement functions into a single integrated mechanism: the slide both provides the translational movement for force transfer and contains the pivot space for arcuate movement. This merging eliminates the need for a long spindle while maintaining operational capability, achieving compact handle positioning without significantly increasing manufacturing complexity.
Solution Approach 2:
The pivot space is nested within the slide structure, with the driver and oblong hole contained within the slide body. This nesting arrangement allows the arcuate movement mechanism to be housed within the compact slide structure, enabling close handle positioning while maintaining the necessary movement range for operation.

AI summary
A valve upper part for inserting into a sanitary fitting includes a head piece, in which a spindle is pivotably mounted, which protrudes from the head piece at the first end of the spindle and engages with a control disk at the second end of the spindle using a pin, which control disk is in contact with a rotationally fixed passage disk, which has at least one through opening, a gripping part being arranged at the first end of the spindle. The gripping part is designed as a slide, which has a pivot space, which accommodates the first end of the spindle in every pivot position and in which a driver element is arranged, by means of which the spindle is connected to the slide.
