Antitheft Link Member for Single-Cable Computer and Interface Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing antitheft methods for computers and interface devices require complex operations involving separate security cables and keys for each device, making it cumbersome to secure both simultaneously.
Innovation Solution
An antitheft device with a link member that can be displaced between two positions, regulating detachment based on the attachment of a security cable, allowing for single-cable protection of both the device and interface, with an engagement mechanism that prevents accidental disconnection during data transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate security cables are attached to both the computer and interface device, then both devices are protected against theft, but the operation complexity increases and key management becomes cumbersome
Solution Approach 1:
The patent combines two separate security cable attachment operations into a single integrated operation. The link member integrates the computer security cable attachment and interface device security cable attachment, allowing both to be secured simultaneously through one attachment action rather than requiring separate operations for each device.
Solution Approach 2:
The link member serves multiple functions: it acts as both the security cable attachment mechanism for the computer and the security cable attachment mechanism for the interface device. This multi-functional design eliminates the need for separate security cable systems and simplifies key management by providing a unified interface.
2Reliability
If separate security cables are attached to both the computer and interface device, then both devices are protected against theft, but the number of security cables and keys increases
Solution Approach 1:
The patent merges the functionality of two separate security cables into a single integrated link member. Instead of requiring one security cable for the computer and another for the interface device, the link member combines both attachment functions, reducing the quantity of security cables from two to one.
3Ease of operation
If the link member can be freely displaced, then attachment/detachment operation is simple, but accidental disconnection may occur during data transfer
Solution Approach 1:
The link member is designed with dynamic characteristics, allowing it to be easily displaced for attachment and detachment operations. The first position enables secure attachment while the second position facilitates simple detachment, providing operational flexibility without compromising connection stability when properly engaged.

AI summary
By attaching a connector 16 to an interface device connector 105, engaging a hook member 17 in a security slot 106, and attaching a security cable 30 to a first security slot 21, displacement of a link bar 19 is regulated by a head portion 32 of the security cable 30 and displacement of the connector 16 and the hook member 17 can be regulated. Since a computer 100 and an interface device 10 can be protected against theft by the single security cable, they can be shifted to the locked state with ease.
