Pluggable Equipment Combination With Segmented Locking Arm
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pluggable device combinations lack a fail-safe, easy-to-implement snap connection mechanism that is user-friendly and efficient.
Innovation Solution
A pluggable device combination featuring a device base and plug-in module with a locking arm and pivot point, where the locking arm's web-like connection point is located on the module housing, forming a pivoting section and actuating section, allowing for a secure and easy release of the locking connection, and incorporating coding elements for secure compatibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a locking arm with pivot point is used to create a snap connection, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The locking arm is segmented into two functional sections: a pivoting section between the pivot point and locking hook, and an actuating section between the pivot point and housing-side connection. This segmentation allows the locking and actuating functions to be independently optimized, enabling easy release operation while maintaining a relatively simple overall structure.
Solution Approach 2:
The locking arm incorporates a pivot point that allows dynamic movement between locked and unlocked positions. The pivoting section can rotate around the pivot point when force is applied to the actuating section, providing dynamic release functionality. This dynamic mechanism achieves easy operation without requiring complex additional components.
2Reliability
If coding elements are integrated into the plug-in module, then the reliability is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The coding elements are merged with the plug-in pockets in a single integrated structure on the module housing. The coding elements protrude from the pocket bottoms and are formed as integral parts of the molding, eliminating the need for separate manufacturing steps and reducing precision requirements while ensuring reliable compatibility coding.
Solution Approach 2:
The coding elements automatically perform the compatibility verification function when the module is inserted into the device base. The hollow coding pins in the base engage with the coding elements during the plugging process, providing self-verifying compatibility checking without requiring additional active components or complex manufacturing precision.
