Burglarproof Device for Electronic Devices Using Lever Arm Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing burglarproof devices for electronic devices are not sufficiently secure and easy to operate, as they often rely on simple locking mechanisms that can be easily compromised, increasing the risk of theft or loss.
Innovation Solution
A burglarproof device featuring a fastener with lever arms surrounding a virtual axis, a control unit with a guiding surface, and a lock core that allows for easy operation between locked and unlocked states, utilizing an elastic member to secure the device to electronic devices through a combination of locking and unlocking mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a simple locking mechanism is used, then the device is easy to operate, but the security is insufficient
Solution Approach 1:
The locking mechanism is divided into multiple independent lever arms (first lever arm, second lever arm, etc.) that can move independently. Each lever arm has its own locking ball and guide surface, creating multiple discrete locking points that collectively provide enhanced security while maintaining operational simplicity through modular design
Solution Approach 2:
The locking balls are nested within recesses on the lever arms, and the lever arms themselves are nested within the housing structure. The control unit is positioned to interact with multiple lever arms simultaneously, creating a nested arrangement where smaller components are contained within larger structural elements, enabling secure multi-point locking
2Reliability
If a secure locking mechanism is implemented, then the security is enhanced, but the operational complexity increases
Solution Approach 1:
The control unit serves multiple functions: it simultaneously controls the movement of multiple lever arms, engages or disengages multiple locking balls, and can be operated through different input methods (button press, rotation, etc.). This multi-functionality consolidates what would otherwise require multiple separate control mechanisms into a single universal control element, enhancing security without proportionally increasing complexity
Solution Approach 2:
Multiple locking functions are merged into a single integrated locking mechanism. The lever arms, locking balls, guide surfaces, and control unit work together as a unified system where the movement of the control unit simultaneously actuates multiple locking components, achieving enhanced security through integration rather than through multiple separate complex mechanisms
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device provides enhanced security by ensuring the fastener is securely attached to electronic devices in a locked state while allowing easy detachment in an unlocked state, addressing the limitations of previous devices by improving operational ease and security.
Implementation Method 1
a locking ball and a guide surface, wherein the control unit moves relative to the fastener and has the guide surface guiding the locking ball to move along the guide surface and toward the virtual axis when the control unit approaches the fastener; the locking ball moves away from the virtual axis when the control unit leaves the fastener

AI summary
A burglarproof device for electronic device including a fastener, a control unit, and a lock core is provided. The fastener includes a plurality of lever arms surrounding a virtual axis. The control unit moves relative to the fastener and drives ends of the lever arms to move toward each other when approaching the fastener; the ends of the lever arms move away from each other when the control unit leaves the fastener. The lock core in an unlocked status permits the movement of the control unit relative to the fastener while the lock core in a locked status restricts the control unit from moving relative to the fastener.
