Modular Device Latch Mechanism for Anti-Theft Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modular computing systems with small form factors are vulnerable to theft due to their compact design, which makes it difficult to secure multiple modules using a single anti-theft device effectively.
Innovation Solution
The modular computing system incorporates a latch mechanism with attachment tabs and a Kensington lock-compatible design, allowing multiple modules to be secured with a single anti-theft device by disabling the latch from changing positions when the lock is inserted, ensuring the modules remain attached and preventing unauthorized removal.

Engineering Contradiction Analysis
1Area of stationary object
If modular computing systems use small form factors to reduce footprint, then the system footprint is reduced, but the vulnerability to theft increases
Solution Approach 1:
The system is divided into multiple modular devices that can be individually secured using the latch mechanism. Each module can be independently attached and detached, allowing the anti-theft device to secure the entire stack while maintaining the compact footprint of individual modules.
Solution Approach 2:
The latch mechanism acts as an intermediary between the attachment tabs and the anti-theft device. It translates the mechanical action of inserting the anti-theft device into a secure locking state, enabling effective anti-theft protection in compact modular designs.
2Ease of operation
If multiple modular devices are secured with a single anti-theft device, then the ease of securing improves, but the complexity of the latch mechanism increases
Solution Approach 1:
Multiple latch mechanisms are merged into a single integrated system that can secure multiple modular devices simultaneously. The latch arms can engage with multiple attachment tabs across different modules, allowing one anti-theft device to control the security of the entire stacked configuration.
Solution Approach 2:
The latch mechanism is designed with universal functionality to handle multiple attachment tabs and modules. The same latch structure can engage with different modules in the stack, providing multi-functional security without requiring separate locking mechanisms for each device.
3Reliability
If the latch is designed to control engagement of attachment tabs, then the security effectiveness improves, but the device complexity increases
Solution Approach 1:
The latch mechanism is designed to automatically engage and disengage based on the insertion and removal of the anti-theft device. The spring-loaded arms naturally move into position to engage attachment tabs when the device is assembled, and automatically release when the anti-theft device is removed, eliminating the need for complex control systems.

AI summary
An example modular device includes a housing having an upper side, a lower side, and a sidewall having a first opening. The modular device also includes an attachment tab to attach the peripheral device to a second modular device at the upper side. The modular device further includes a latch disposed within the housing. The latch includes a main body having a second opening aligned with the first opening to receive an anti-theft device. The latch also includes a latch arm extending from the main body to control an engagement of the attachment tab with the second modular device. The latch further includes a latch unlocking tab exposed at the lower side to control a position of the latch.
