Hinged Module Locking for Secure Computer Chassis Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Computer systems lack effective mechanisms to prevent unauthorized removal of modules from a chassis, which can lead to system malfunction, data unreliability, and theft, as existing designs primarily rely on mechanical couplings that do not provide a locking mechanism to inhibit removal.
Innovation Solution
A module locking device with a first member coupled to the chassis and a second member connected via a hinge, allowing the second member to pivot between a locked position that inhibits removal and an unlocked position that facilitates removal, utilizing a locking mechanism, such as a keyed fastener, to secure the second member in the locked position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mechanical coupling device is used to secure modules to the chassis, then the module is prevented from unintentionally sliding out, but the device does not provide adequate protection against unauthorized removal
Solution Approach 1:
The locking device incorporates a movable second member that can pivot between a first position (blocking module removal) and a second position (facilitating module removal). This dynamic mechanism allows the system to transition between secure and accessible states, resolving the contradiction between preventing unauthorized removal and enabling legitimate maintenance operations
Solution Approach 2:
The locking mechanism acts as an intermediary between the module and the chassis, controlling the interaction between them. By introducing this intermediate locking component, the system achieves both secure attachment (preventing unauthorized removal) and controlled accessibility (allowing legitimate removal with proper authorization), thus resolving the technical contradiction
2Ease of manufacture
If modules are easily removable from the chassis, then installation and maintenance is simplified, but unauthorized removal and theft become more feasible
Solution Approach 1:
The locking device is segmented into multiple functional members: a first member coupled to the chassis, a second member that pivots to block or facilitate removal, and a locking mechanism. This segmentation allows each component to perform its specific function while collectively providing both ease of legitimate assembly and protection against unauthorized removal
Solution Approach 2:
The locking feature is applied locally at the module-chassis interface rather than requiring complete system redesign. The locking device integrates seamlessly with the existing mechanical coupling while adding security functionality only where needed, maintaining ease of assembly for legitimate operations while preventing unauthorized removal
3Reliability
If a locking mechanism is added to prevent unauthorized module removal, then security is improved, but device complexity increases
Solution Approach 1:
The locking mechanism is merged with the existing mechanical coupling structure. The first member couples to the chassis, the second member couples to the first member via a hinge, and the locking mechanism selectively locks the second member. This integration combines security functionality with the existing module attachment system, providing protection without requiring a completely separate complex locking system

AI summary
Provided in some embodiment is a module locking device including a first member coupled to a computer chassis during use, a second member coupled to the first member via a hinge. The hinge enables the second member to move between a first position that inhibits removal of one or more modules from the computer chassis during use and a second position that facilitates removal of one or more modules from the computer chassis during use. The module locking device also includes a locking mechanism that selectively locks the second member in the first position to inhibit removal of one or more modules from the computer chassis during use.
