Lever Adapter with Extendable Legs for Vehicle Lifting Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for lifting vehicles during emergency rescue operations are inefficient, as they require extensive time, multiple components, and lack stability, especially when dealing with newer vehicles with unpredictable behavior due to their design and materials.
Innovation Solution
A portable and universal lever adapter device that can be used with various jacks, featuring extendable and retractable support legs with stabilizing feet and a jack attachment piece, allowing for quick and stable lifting of vehicles by distributing the load and providing a tripod-like stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional jacks with single contact point structures are used, then the device is simple and inexpensive, but the vehicle becomes unstable and unsafe when lifted
Solution Approach 1:
The jack structure is segmented into multiple contact points (at least two contact points) instead of a single contact point, allowing the load to be distributed across multiple locations on the vehicle undercarriage, thereby improving stability and safety during lifting operations
Solution Approach 2:
The jack design transitions from a single-point contact (zero-dimensional contact) to multi-point contact (distributed contact across space), adding spatial dimensionality to the contact structure, which enhances stability by creating a more robust support geometry
2Productivity
If airbag method is used to lift vehicles, then lifting capability is achieved, but multiple components and extensive time are required
Solution Approach 1:
The jack is designed with universal adaptability to work with various vehicle types and undercarriage configurations through multiple contact points and adjustable features, eliminating the need for specialized equipment like airbags for different vehicle scenarios
Solution Approach 2:
The jack structure is pre-configured with multiple contact points and stabilization features before deployment, allowing for immediate and efficient lifting without the need for preliminary setup of multiple components or inflation sequences required by airbag systems
3Ease of operation
If vehicle undercarriage is close to the ground, then vehicle design is compact, but access for rescuers becomes inconvenient and difficult
Solution Approach 1:
The jack incorporates dynamic adjustment capabilities with movable contact points and adjustable support structures that can adapt to varying clearance heights, allowing rescuers to access the undercarriage area more easily even when the vehicle sits low to the ground
