Spring-Reset Locking Assembly for Easy Board Card Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing locking assemblies require additional force to maintain an unlocked state when separating a board card from a bracket, and they do not automatically return to their original position after unlocking, making the process cumbersome.
Innovation Solution
A locking assembly with an elastic member and rotating member that automatically locks and unlocks a terminal element, allowing it to be easily secured and released without additional force, featuring a sliding block and rotating mechanism that uses the elastic member's rebound force to return to its original position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a locking assembly is used to fix a board card on a bracket, then the board card is secured against vibration and impact, but additional force is required to maintain the unlocked state when separating the board card
Solution Approach 1:
The locking assembly employs a rotating member that can dynamically transition between locked and unlocked states. The rotating member rotates about an axis to engage or disengage the locking protrusion from the locking groove, enabling easy state transitions without requiring sustained force to maintain the unlocked state.
Solution Approach 2:
The elastic member provides self-service by automatically returning the rotating member to its initial position after unlocking. When the locking force is removed, the elastic member's restoring force automatically resets the rotating member, eliminating the need for additional force to maintain the unlocked state and preparing the assembly for the next locking operation.
2Device complexity
If a locking assembly requires additional force to maintain unlocked state, then the locking mechanism remains simple, but the unlocking process becomes cumbersome
Solution Approach 1:
The locking mechanism replaces complex multi-component mechanical systems with a simplified structure consisting of a rotating member with locking and unlocking portions. The rotating member works in conjunction with a sliding block and elastic member to achieve both locking and automatic resetting functions, reducing overall device complexity while improving ease of operation.
3Device complexity
If the locking assembly does not automatically return to original position, then the structure remains simple, but the locking process becomes cumbersome requiring manual resetting
Solution Approach 1:
The elastic member connected to the rotating member provides automatic resetting functionality. When the rotating member is rotated to the unlocked position, the elastic member stores potential energy and automatically returns the rotating member to its initial locked position, enabling rapid successive locking operations without manual resetting and improving overall locking efficiency.

AI summary
A locking assembly includes a fixing mechanism, an elastic member, a sliding block, and a rotating member. The fixing mechanism defines a sliding groove and a receiving groove. The sliding groove extends along a first direction. The elastic member is disposed in the receiving groove. The sliding block is movably disposed in the fixing mechanism along a second direction. The sliding block includes a first blocking portion and a first protruding portion. The first protruding portion protrudes from the receiving groove along the first direction. The rotating member rotatably is disposed on the fixing mechanism. The rotating member includes a second protruding portion. The second protruding portion can rotate around the first direction and resist against the first protruding portion, such that the second protruding portion drives the sliding block to move along the second direction to compress the elastic member.
