Grip Locking Structure for Terminals With Cable Load Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional locking devices for terminals, such as smartphones and laptops, are inefficient in preventing unauthorized use and theft, as they can be easily bypassed by thieves after the device is stolen, and are limited to securing devices mounted on vehicles.
Innovation Solution
A grip-type locking device that physically and electrically secures terminals using a body with grips, an interval adjusting pin, and a cable connected to a controller, which absorbs external forces and prevents damage to connectors, allowing for secure use within a user's control range and immediate theft detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If GPS-based authorized area restriction is used, then terminal location can be tracked and unauthorized use restricted, but the terminal can still be easily released by thieves after theft
Solution Approach 1:
The locking device is divided into separate functional components: a body portion that attaches to the terminal, a cable portion that physically restrains the terminal, and a controller portion that monitors security status. This segmentation allows the physical locking function to be independently robust while maintaining system simplicity.
Solution Approach 2:
The locking device is activated before theft occurs, physically restraining the terminal through the cable and grip mechanism. This preliminary physical constraint prevents the terminal from being easily removed or released by thieves, addressing the limitation of post-theft tracking systems.
2Reliability
If the cable is directly connected to the terminal connector, then electrical connection is maintained, but external forces can damage the connector
Solution Approach 1:
The body portion serves as an intermediary between the cable and the terminal connector. It provides a secure attachment point for the cable while maintaining electrical connection to the terminal, thereby preventing external forces applied to the cable from directly damaging the connector.
Solution Approach 2:
The body structure is designed to absorb and distribute external forces before they reach the connector. This beforehand cushioning protects the vulnerable connector from damage during theft attempts or accidental pulls on the cable.
3Reliability
If a secure physical locking mechanism is implemented, then theft prevention is improved, but the device becomes more complex and expensive
Solution Approach 1:
The locking function, electrical connection, and physical restraint functions are merged into a single integrated device. The body, cable, and controller work together as one unit, eliminating the need for separate locking mechanisms and reducing overall system complexity and manufacturing cost.
Solution Approach 2:
The device performs multiple functions simultaneously: physical locking through the cable and grip, electrical connection through the connector, and security monitoring through the controller. This multi-functionality reduces the need for additional components and simplifies the overall system.

AI summary
Disclosed herein is a grip-type locking device for a terminal. The locking device includes a body. Two grips are connected to opposite sides of the body, respectively. An interval adjusting pin adjusts an interval between the two grips, thus locking or releasing the terminal interposed therebetween. A cable is connected at opposite ends thereof to a controller and the terminal, respectively. The cable is securely coupled to the body so that load applied to the cable on the controller is blocked by the body and thus is not transmitted to the cable on the terminal.
