Sanitary Valve Handle Alignment for Precise Rotary Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rotary handle devices for sanitary valves lack the ability to adjust the handle operating element's rotary position precisely relative to a defined functional position of the rotary adjustable unit, limiting their adjustability and alignment capabilities.
Innovation Solution
A rotary handle device with a user-operable alignment unit that allows the handle body parts to rotate steplessly within an alignment angle range, enabling continuous rotation and precise alignment of the handle operating element relative to the rotary adjustable unit, even when the handle body is coupled in a single or multiple discrete rotational positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the handle body is coupled to the rotary-adjustable unit in discrete rotational positions, then the coupling is simple and reliable, but the handle operating element cannot be positioned precisely relative to the rotary-adjustable unit
Solution Approach 1:
The handle body is divided into two separable parts: a first handle body part that couples to the rotary-adjustable unit, and a second handle body part that carries the handle operating element. This segmentation allows independent positioning of each part, enabling precise alignment while maintaining simple coupling mechanisms.
Solution Approach 2:
The alignment unit enables dynamic adjustment of the rotational position of the second handle body part relative to the first handle body part. This dynamic capability allows the handle operating element to be positioned precisely at any desired angular position, not just at discrete coupling positions.
2Adaptability or versatility
If the handle body can only be coupled in a single rotational position, then the coupling structure is simple, but the handle operating element lacks adjustability
Solution Approach 1:
Dividing the handle body into two parts with an alignment unit between them provides adjustability without requiring multiple coupling positions. The first part maintains simple single-position coupling, while the second part can be independently aligned through the alignment unit.
Solution Approach 2:
The alignment unit acts as an intermediary mechanism between the two handle body parts. It provides the necessary adjustment capability while keeping the coupling to the rotary-adjustable unit simple and straightforward.
3Ease of operation
If adjacent coupling rotational positions are spaced apart by a fixed angular distance, then the coupling positions are well-defined, but continuous adjustment of the handle operating element is not possible
Solution Approach 1:
The alignment unit introduces dynamic adjustability, allowing the second handle body part to be rotated to any angular position within an alignment angle range. This enables continuous positioning of the handle operating element, making precise alignment of markings possible while maintaining well-defined coupling positions.
