Locking Link With Integrated Cam Cover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional security link devices require an additional padlock to function securely, making them cumbersome and difficult to operate due to their weight and complexity, especially when locking and unlocking securing members like chains.
Innovation Solution
A locking link device that integrates a cover and link mechanism, allowing for secure locking and unlocking without the need for a separate padlock, where the cover moves between locked and unlocked positions to facilitate easy operation with a single hand.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an additional padlock is used to secure the link device, then security is improved, but weight and device complexity increase
Solution Approach 1:
The patent integrates the locking mechanism directly into the link device by incorporating a movable cover that can transition between open and closed positions. The cover includes a cam surface that engages with a cam follower on the link body, creating an integrated locking system that eliminates the need for separate padlocks while maintaining security functionality.
Solution Approach 2:
The link device is designed to perform multiple functions: it serves as both a connecting link and a locking mechanism. The movable cover with cam surface provides locking capability, while the same structure allows for easy opening and closing operations, making the device universal and eliminating the need for additional specialized locking components.
2Reliability
If an additional padlock is used to secure the link device, then security is improved, but weight increases
Solution Approach 1:
The locking function is merged into the link device structure itself. The cover and cam mechanism are integrated components that provide locking capability without requiring a separate padlock, thereby eliminating the additional weight that would be imposed by a standalone locking device.
3Reliability
If a separate padlock is used with the link device, then security is improved, but ease of operation deteriorates due to cumbersome handling
Solution Approach 1:
The locking and unlocking operations are simplified by integrating the mechanism into a single movable cover that can be operated with one hand. The cam surface and follower arrangement allows the cover to be easily moved between positions, eliminating the cumbersome two-handed operation required by traditional padlocks.
Solution Approach 2:
The cover is designed to be movable rather than fixed, allowing it to transition smoothly between open and closed positions. This dynamic design enables easy operation where the cover can be freely moved to lock or unlock the device, contrasting with the static, difficult-to-operate traditional padlock systems.
