Sliding Mechanism Locking Structure for Impact-Resistant Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sliding mechanisms in personal computers, involving exterior, intermediate, and interior plates, are prone to damage from external impacts due to complex structures and high manufacturing costs, with components like stop blocks and locking elements being easily damaged.
Innovation Solution
A slide positioning device with an exterior plate featuring a stop block, an intermediate plate equipped with a pivot element and resilient element, and an interior plate with a push element, allowing for stable sliding action without damage under external forces by using a pivot element that disengages from the stop block upon deformation of the resilient element.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional sliding mechanism uses multiple components (locking element, stop block, resilient element) to provide stability, then the server can be securely retained when pulled outward, but the structure becomes complicated and manufacturing expense increases
Solution Approach 1:
The patent combines the locking element and stop block into a single integrated structure on the intermediate plate. The stop block is formed as an integral part of the intermediate plate rather than a separate component, reducing the total number of parts while maintaining the locking function through the interaction between the stop block and the resilient element.
Solution Approach 2:
The intermediate plate serves multiple functions: it acts as a structural support, incorporates the stop block for positioning, houses the resilient element for locking, and provides the locking mechanism itself. This multi-functionality reduces the need for separate dedicated components for each function.
2Reliability
If a conventional sliding mechanism uses a stop block and locking element to prevent sliding, then stability is provided, but these components are easily damaged under external impact
Solution Approach 1:
The resilient element is pre-installed in a compressed or tensioned state to provide cushioning protection to the stop block and locking mechanism. When external impact occurs, the resilient element absorbs and dissipates the shock energy, preventing direct transmission to the fragile locking components and reducing the risk of damage.
Solution Approach 2:
The patent utilizes the external impact force to trigger the release mechanism. When impact exceeds a certain threshold, it causes the resilient element to deform beyond its normal range, automatically disengaging the locking mechanism and allowing the plates to slide. This converts harmful impact into a beneficial automatic release function.
3Ease of operation
If the intermediate plate is pulled outward from the exterior plate, then the server can be accessed for repair, but great impact can cause ruin of the sliding mechanism
Solution Approach 1:
The locking mechanism is designed to be dynamic rather than fixed. The resilient element can deform under load, allowing the system to adapt to different force conditions. During normal operation, the mechanism maintains a stable locked state for easy server access. Under excessive impact, the dynamic response allows automatic release or deformation to prevent catastrophic failure.
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
The solution simplifies the structure, reduces damage from external impacts, and maintains stability during server removal and reinstallation, enhancing the durability and cost-effectiveness of the sliding mechanism.
Implementation Method 1
a resilient element that is mounted securely on the inner side surface and that has a free end in contact with the front end of the pivot element; and the interior plate having a push element that is fixed on the outer side surface and that is formed with a cam face. When an external force applied on the exterior plate so as to cause sliding action between the interior plate and the intermediate plate results in abutment of the cam face of the push element against the resilient element, thereby deforming the free end of the resilient element, which in turn rotates the pivot element about its axis

AI summary
A positioning device for a sliding mechanism includes slidably connected exterior plate, intermediate plate and interior plate, characterized by the exterior plate having a stop block; the intermediate plate formed with a through hole, including having a pivot element mounted pivotally adjacent to the through hole and having a projection extending through the hole to engage the stop block, thereby preventing sliding action between the exterior and intermediate plates, a resilient element having a free end in contact with the rear end of the pivot element; and the interior plate having a push element with cam face; when an external force applied on so as to cause sliding action between the interior plate and the intermediate plate results in abutment of the cam face against the resilient element, thereby deforming the resilient element and rotating the pivot element about its axis, thereby disengaging the projection from the stop block.
