Rotating Locking Part with Radial Spring Webs for Fastening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening arrangements are complex and difficult to easily interconnect and disengage two elements, as they require precise rotation and compression of spring elements to secure the connection.
Innovation Solution
The fastening arrangement employs radially resilient spring webs with web wings that move between a mounted and demounted position, utilizing bearing tenons and depressions to engage and disengage catch noses with the second element, allowing simple mating and separation by rotating the locking part.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rotatable locking part with spring element is used to interconnect two elements, then the connection can be secured, but the operation becomes complex and difficult to easily interconnect and disengage
Solution Approach 1:
The locking part is segmented into distinct functional components: a head plate for engagement, a foot shaft for rotation, radially resilient spring webs for catching, and catch noses for interlocking with the second element. This segmentation allows each component to perform its specific function independently, simplifying the overall operation while maintaining secure connection.
Solution Approach 2:
The locking part utilizes dynamic movement through rotation to transition between locked and unlocked states. The radially resilient spring webs dynamically adjust their position based on rotational angle, automatically engaging or disengaging catch noses from the second element without requiring manual compression or complex manipulation.
2Reliability
If precise rotation and compression of spring elements are required, then secure connection is achieved, but the operation becomes difficult and time-consuming
Solution Approach 1:
The locking mechanism is designed to be self-actuating through rotation. The radially resilient spring webs automatically compress and expand based on the rotational position of the foot shaft, and the catch noses automatically engage or disengage from the second element. This self-service mechanism eliminates the need for separate compression actions or precise manual manipulation, significantly reducing operation time while maintaining secure connection.
3Reliability
If catch noses engage behind the second element in mounted position, then secure interconnection is achieved, but disengagement requires complex rotation and spring compression
Solution Approach 1:
The disengagement mechanism utilizes dynamic rotation of the foot shaft to automatically transition the spring webs between engaged and disengaged states. Rotating the foot shaft by at least 90 degrees causes the radially resilient spring webs to shift position, automatically releasing the catch noses from the second element without requiring separate compression or manipulation steps, thereby simplifying the disengagement process.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design enables easy interconnection and disconnection of elements by shifting catch noses in and out of engagement, providing a secure connection in the mounted position and releasing in the demounted position, simplifying the process.
Implementation Method 1
resilient spring webs movable in a radial direction are configured on the foot shaft

AI summary
A fastening arrangement includes a locking part having a head plate and a foot shaft configured with catch noses, bearing tenons, and spring webs having catch noses and web wings. The receiving element includes a profiled surface and an edge wall including inwardly convex portions and outwardly concave portions. When the locking part is in a mounted position, the bearing tenons are disposed in first depressions while the spring webs are in a rear engagement position in which the catch noses engage behind an element. When the locking part is in a demounted position, the bearing tenons are disposed in second depressions and the spring webs are in a released position in which they are out of engagement with the element.
