Computing Tray Lock Assembly for Accidental Latch Release Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Computing trays in computing systems are prone to accidental release due to unintentional contact with the latch, disrupting the system.
Innovation Solution
A lock assembly with a fixed and movable bracket system that can be adjusted between a releasing and secured position, preventing the latch from activating when touched accidentally.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a simple latch mechanism is used for releasing the computing tray, then the ease of operation is improved, but the reliability deteriorates due to accidental release
Solution Approach 1:
The locking mechanism is divided into two independent components: a latch for releasing the tray and a separate lock assembly for preventing accidental release. This segmentation allows each component to perform its specific function - the latch provides easy operation while the lock assembly ensures reliability by requiring intentional manipulation to disengage.
Solution Approach 2:
The lock assembly acts as an intermediary between the user and the latch mechanism. It mediates the interaction by providing an additional control layer - the movable bracket must be deliberately positioned to allow latch operation, thereby preventing accidental triggering while maintaining intentional accessibility.
2Reliability
If a lock assembly is added to prevent accidental release, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The lock assembly incorporates a movable bracket that can dynamically switch between a locked position (blocking the latch) and an unlocked position (allowing latch operation). This dynamic element provides the security function without requiring a completely separate locking mechanism, thereby limiting the increase in device complexity.
Solution Approach 2:
The lock assembly is integrated with the existing latch mechanism rather than being a completely separate system. The movable bracket combines with the latch structure to provide both security and release functions, merging multiple functions into a unified assembly that minimizes additional complexity.
3Reliability
If the movable bracket is positioned to block the latch, then the reliability is improved, but the ease of operation deteriorates due to additional manipulation steps
Solution Approach 1:
Before releasing the computing tray, the user must first disengage the movable bracket from the blocking position. This preliminary action ensures intentional operation while maintaining a simple subsequent latch release process. The bracket can be easily moved to the disengaged position, minimizing the additional effort required.

AI summary
A computing system includes a computing tray for receiving a computing device; a latch attached to the computing tray for releasing the computing tray during installation or removal operations; and a lock assembly for preventing accidental release of the computing tray. The lock assembly includes a fixed bracket having two fixed sides, one of the fixed sides being a mounting side attached to the computing tray near the latch; and a movable bracket having two movable sides attached respectively to the two fixed sides. The movable bracket is adjustable relative to the fixed bracket between a releasing position and a secured position. The movable bracket allows the latch to release the computing tray in the releasing position, and the movable bracket physically blocks the latch from releasing the computing tray in the secured position.
