Innovation Solution
A locking device with a flat base plate and oblong detent springs that can be mounted on a printed circuit board, allowing for precise and reliable locking of adjusting means without pressure on one side, enabling easy installation and access, and featuring a design that can be attached using standard fastening means or pretensioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cylindrical projecting engaging means is used for locking the adjusting means, then locking engagement is achieved, but precise locking becomes difficult when the adjusting means is moved quickly and high manufacturing precision is required
Solution Approach 1:
The locking device is divided into separate functional components: a base plate mounted on the printed circuit board and detent springs that engage with the adjusting means. This segmentation allows each component to be optimized independently, reducing the need for high overall manufacturing precision while maintaining reliable locking engagement.
Solution Approach 2:
The detent springs provide a dynamic locking mechanism that can quickly engage and disengage from the adjusting means positions. The spring mechanism allows for rapid response to quick movements of the adjusting means, achieving reliable locking without requiring extremely precise manufacturing tolerances.
2Reliability
If a cylindrical projecting engaging means is used for locking, then locking engagement is achieved, but the installation height of the adjusting means increases
Solution Approach 1:
The locking mechanism transitions from a vertical cylindrical engagement to a planar arrangement where detent springs engage with positioning elements on the adjusting means. This dimensional change allows the locking function to be achieved within the plane of the printed circuit board, reducing the installation height.
3Reliability
If a cylindrical projecting engaging means is used for locking, then locking is achieved, but the force load on one side of the adjusting means becomes uneven
Solution Approach 1:
Multiple detent springs are distributed at different locations on the base plate, each engaging with corresponding positioning elements on the adjusting means. This distribution of locking points ensures that the force load is evenly distributed across multiple contact points rather than concentrated on one side, preventing uneven force distribution.
