Segmented Holding Nut for Stainless Steel Sensor Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing measuring devices face challenges in reliably mounting stainless steel evaluation modules with deep drawing production methods onto conventional cast housings, especially in applications with hygiene requirements, due to the inordinately large effort required for implementing screw threads.
Innovation Solution
A measuring device design featuring a sensor module with a first screw thread and an evaluation module with a second screw thread, where the threads are secured by clamping limbs and an actuating element, allowing for secure engagement and rotation prevention, with a holding nut that interlocks shape-wise and axially, enabling reliable mounting of stainless steel evaluation modules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If stainless steel housings are produced by deep drawing method for hygiene requirements, then hygiene compliance and material durability are improved, but implementation of screw threads becomes excessively difficult and time-consuming
Solution Approach 1:
The holding nut is segmented by a slit into two clamping limbs that can independently deform to engage with the screw thread, allowing the stainless steel housing to be divided into functional segments that simplify thread implementation while maintaining hygiene standards
Solution Approach 2:
The clamping limbs are designed to be dynamically deformable through the slit, allowing them to flex during engagement with the screw thread and then lock into position, transforming a static rigid structure into a dynamic adaptive connection that is easier to manufacture
2Ease of manufacture
If conventional cast housings with screw threads are used, then ease of thread implementation is improved, but hygiene requirements and material suitability for certain applications are compromised
Solution Approach 1:
The solution combines stainless steel material (for hygiene compliance) with a composite connection mechanism involving the holding nut with clamping limbs, creating a hybrid system that achieves both hygiene requirements and ease of thread implementation
3Reliability
If screw threads are securely engaged to prevent rotation, then mounting reliability is improved, but device complexity increases due to additional clamping and rotation prevention mechanisms
Solution Approach 1:
The holding nut merges multiple functions into a single component: it provides clamping force through the deformable limbs, prevents rotation through the engagement geometry of the limbs with the screw thread, and maintains axial positioning, thereby reducing overall device complexity while improving mounting reliability

Implementation Method 1
an actuating element, which acts on the first clamping limb and on the second clamping limb, and which deflects the clamping limbs relative to one another, whereby the first screw thread and the second screw thread are clamped against one another and are secured against rotation relative to one another

AI summary
A measuring device comprises a sensor module and an evaluation module mounted on the sensor module. The sensor module includes a first component having a first screw thread, and the evaluation module includes a second component having a second screw thread. The screw threads engage with one another by screwing; wherein the first or the second component has a slit, which essentially extends into the component in a plane perpendicular to the thread axis; and there are formed by the slit a first clamping limb and a second clamping limb of the component, which are separated from one another by the slit. On the component there is furthermore arranged an actuating element, which acts on the first clamping limb and the second clamping limb, and deflects the clamping limbs relative to one another, whereby the first screw thread and the second screw thread are clamped against one another and secured against rotation relative to one another.
