Grip Locking Structure for Terminals With Connector Load Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional locking devices for terminals are inefficient in preventing unauthorized use and theft, especially for portable devices like smartphones and tablets, as they can be easily bypassed or require location tracking after the device is stolen.
Innovation Solution
A grip-type locking device that physically and electrically secures the terminal, using a cable with an integrated injection-molded part to prevent load transmission to connectors, and a controller to activate an alarm during theft attempts, ensuring the terminal remains locked within a user's control range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If GPS tracking and authentication software are used to prevent terminal theft, then location tracking capability is improved, but response time after theft occurs is delayed
Solution Approach 1:
The locking device is pre-installed on the terminal before theft occurs. The grip structure and locking mechanism are already in place, ready to immediately restrict terminal use upon detection of theft, eliminating the time delay associated with post-theft tracking and authentication procedures.
Solution Approach 2:
The device implements preliminary anti-theft measures through physical locking mechanisms that prevent terminal removal or unauthorized access before theft can be completed. The alarm system is pre-configured to trigger immediately upon detection of forced removal, counteracting the theft attempt in real-time rather than after the fact.
2Reliability
If the terminal is securely mounted to prevent separation, then theft prevention is improved, but the connector and communication port may be damaged by external forces
Solution Approach 1:
The cable acts as an intermediary element between the locking mechanism and the terminal connector. It absorbs and redirects external forces applied during theft attempts away from the vulnerable connector and communication port, protecting these components from damage while maintaining effective theft prevention.
Solution Approach 2:
The vulnerable connector and communication port are extracted from the direct path of external forces by positioning them separately from the main locking structure. The cable routing and connector placement are designed so that force applied to the locking mechanism does not directly transmit to the connector, isolating these components from harmful stress.
3Reliability
If a complex locking mechanism is used to prevent unauthorized use, then security is improved, but device complexity and cost increase
Solution Approach 1:
Multiple security functions are merged into a single integrated locking device structure. The grip mechanism, alarm system, and physical locking features are combined in one unit, providing comprehensive security without requiring multiple separate components or complex configurations.
Solution Approach 2:
The locking device is designed for self-service operation with intuitive grip-based locking and release mechanisms. The terminal user can easily secure and release the device without requiring complex authentication procedures or technical knowledge, maintaining high security while minimizing operational complexity.

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.
