High-Lift Jack Safety Link for Secure Shackle Tab Lifting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current high-lift jack adaptors are unsecure and unstable, prone to slipping out of place during use, posing safety risks in lifting operations.
Innovation Solution
A safety link system comprising an upper bracket and a lower bracket with slots for secure attachment to a vehicle shackle tab and a jack's lift pad, utilizing clevis pins and cotter pins for stability and prevention of slippage, designed to connect a jack to a vehicle bumper through shackle tabs, enhancing safety and stability during lifting operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional jack adaptors are used to connect jack to vehicle, then the lifting operation can be performed, but the connection becomes unsecure and unstable, prone to slipping out of place
Solution Approach 1:
The safety link is divided into two separate brackets: an upper bracket for securing to the vehicle shackle tab and a lower bracket for securing to the jack runner. This segmentation allows each bracket to be optimized for its specific connection point, ensuring secure attachment at both ends independently and preventing slippage during lifting operations.
2Device complexity
If a simple connection method is used, then the device complexity is reduced, but the stability and anti-slippage performance deteriorates
Solution Approach 1:
The safety link acts as an intermediary component between the jack and the vehicle shackle tab. It includes an upper bracket with slots for the shackle tab and a lower bracket with slots for the jack runner, providing a stable and secure connection that prevents slippage while maintaining reasonable structural simplicity.
3Reliability
If the safety link uses multiple slots and pins for secure attachment, then connection reliability improves, but the ease of operation decreases due to more assembly steps
Solution Approach 1:
The upper and lower brackets each include multiple slots that can accommodate different positions and orientations of the shackle tab and jack runner slots. This universal design allows the same bracket structure to work with various vehicle and jack configurations, maintaining ease of operation while ensuring reliable attachment through proper slot alignment and pin securing.
