Adjustable Lock Device for Universal Anti-Theft Hole Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lock devices for electronic devices require multiple versions to accommodate different anti-theft lock hole specifications, making them uneconomical and inconvenient to use.
Innovation Solution
A lock device with a housing, rotating hooks, and a driving mechanism that can adjust its width by moving along different axes, allowing it to fit various lock hole sizes, and a braking element for secure locking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a lock device is designed for a specific anti-theft lock hole specification, then it can securely lock that particular size, but it cannot accommodate different lock hole sizes, requiring multiple versions
Solution Approach 1:
The lock device employs a rotating hook mechanism that can dynamically adjust its opening width by rotating between different positions. The hook rotates relative to the housing along a plane parallel to the X-Y plane, allowing the front-end portion to open to different widths corresponding to different lock hole sizes. This dynamic adjustment eliminates the need for multiple static lock device versions.
Solution Approach 2:
The lock device is designed with universal adaptability to accommodate multiple lock hole specifications through a single device. The driving device can be selectively moved to extend along the Z-axis by different depths, enabling the same lock device to fit various lock hole sizes without requiring separate devices for each specification.
2Adaptability or versatility
If multiple lock device versions are purchased for different specifications, then each version fits its specific lock hole size, but it increases cost and storage requirements
Solution Approach 1:
The lock device integrates multiple functions into a single unit, allowing it to accommodate different lock hole specifications through the adjustable rotating hook mechanism. Users only need to carry one lock device instead of multiple versions, reducing both quantity and storage requirements.
Solution Approach 2:
The dynamic rotating hook mechanism enables a single lock device to adapt to different lock hole sizes on-demand, eliminating the need to purchase and carry multiple static versions for different specifications.
3Adaptability or versatility
If the rotating hook opens to a larger width, then it can accommodate larger lock holes, but it reduces the locking security for smaller lock holes
Solution Approach 1:
The rotating hook dynamically adjusts its opening width based on the lock hole size being used. When locked, the lock body restricts the movement of the driving device to specific positions that ensure proper engagement. The hook can rotate to different positions along the X-Y plane, with each position optimized for specific lock hole sizes, maintaining security while providing adaptability.
Solution Approach 2:
The lock body includes a braking element that protrudes to engage with the force applying member at specific positions, creating localized locking points. The guide ramp with steps provides discrete positioning options, ensuring that the hook engages at the correct width for each lock hole specification, thereby maintaining reliability across different sizes.

AI summary
A lock device is provided. The lock device includes a housing with a front opening at an end; a rotating hook disposed in the housing and being rotatable relative to the housing, the rotating hook including a front-end portion and a rear-end portion, the front-end portion at least partially protruding from the front opening, and the rear-end portion extending toward a direction opposite to the front-end portion; a driving device disposed in the housing and selectively moveable to change widths by which the front-end portion is opened respectively; and a lock body disposed in the housing, when the lock body is locked, the lock body restricting a movement of the driving device.
