Computing Device Security Cable With Lock Unit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Computing devices are vulnerable to both physical theft and electronic intrusion, as physical security measures do not adequately prevent unauthorized access to electronic data, and can be defeated to allow both theft and intrusion.
Innovation Solution
A security cable system that includes a restraining cable with a lock unit, which can be configured to tether a computing device to a stationary object and place it in an inactive state, using a key interface to switch between locking and unlocking configurations, and includes a power connector to supply operating power while verifying identification information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a wire is used to physically tether a computing device to a stationary object, then physical movement of the device is prevented, but the device remains vulnerable to electronic intrusion and unauthorized access to electronic data
Solution Approach 1:
The patent combines physical tethering and electronic security controls into a single integrated security cable system. The lock unit integrates both a physical locking mechanism and an electronic circuit that communicates with the computing device, merging two separate security functions into one unified system that simultaneously provides physical restraint and electronic access control.
Solution Approach 2:
The security cable is designed to perform multiple functions: it physically tethers the device to prevent theft, electronically places the device in an inactive state to prevent unauthorized access, and can provide power to the device. This multi-functional approach addresses both physical security concerns and electronic security vulnerabilities through a single device.
2Reliability
If a lock unit is used to fasten the computing device, then physical theft is prevented, but the device cannot be easily accessed when needed
Solution Approach 1:
The lock unit incorporates a key interface that allows dynamic switching between locked and unlocked states. When the security cable key is inserted and rotated, the lock unit transitions from a fastened state to an unlocked state, enabling easy access to the device when needed while maintaining strong security when the key is removed.
Solution Approach 2:
The security cable key serves as an intermediary element that mediates between the user and the lock unit. The key interface requires the key as a mediator to transition the lock state, providing controlled access without requiring complex authentication procedures or permanent fastening mechanisms.
3Object-affected harmful factors
If the lock unit places the computing device in an inactive state, then electronic access is blocked, but the device cannot function normally
Solution Approach 1:
The electronic circuit in the lock unit dynamically changes the device state between active and inactive based on the presence of the security cable key. When the key is inserted, the device transitions to an active state allowing full functionality; when the key is removed, the device transitions to an inactive state blocking unauthorized access. This dynamic state change resolves the contradiction between security and functionality.

AI summary
A security cable can include a restraining cable and a lock unit attached to the restraining cable. The lock unit can be configured to removably fasten to a computing device. The lock unit can be further configured to switch the security cable between a first configuration and a second configuration. In the first configuration, the lock unit can be fastened to the computing device and can place the computing device in an inactive state. In the second configuration, the lock unit can be removable from the computing device and may not place the computing device in the inactive state.
