Universal Jack Stand With Continuous Opening for Stable Jacking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Standard jack stands are not compatible with contemporary vehicle jacks and often require placement away from designated jacking locations, leading to instability and potential vehicle damage when used with scissor or floor jacks.
Innovation Solution
A jack stand design featuring a hollow body with a continuous opening at the top and a jack pad with a downturned rail and extension, allowing the jack pad to be supported by the jack stand while maintaining support at the manufacturer-designated jacking location, ensuring stability and compatibility with various jacks and vehicles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If standard jack stands are used with separate support structures, then the jack stand can support the vehicle, but it cannot support the vehicle at the same location as the jack, requiring placement away from designated jacking locations
Solution Approach 1:
The jack stand is designed to surround and integrate with the jack structure, merging the support functions of both devices. The hollow body configuration allows the jack to be positioned within the jack stand, enabling both devices to operate at the same location rather than requiring separate placement positions.
Solution Approach 2:
The jack stand employs a nested structure where the hollow body encompasses the jack, allowing the jack to be inserted into the jack stand's cavity. This nesting arrangement enables the jack stand to support the vehicle at the exact same location as the jack, eliminating the need to place the jack stand at a different position.
2Ease of manufacture
If jack stands are designed with fixed support structures, then manufacturing is simplified, but compatibility with different types of jacks and vehicles is reduced
Solution Approach 1:
The jack stand is designed with a universal hollow body structure that can accommodate multiple types of jacks (scissor jacks, floor jacks, racing jacks) and different vehicle configurations. This multi-functional design allows a single jack stand model to work with various jack types and vehicle platforms without requiring complex specialized components.
Solution Approach 2:
The jack stand incorporates an adjustable support platform with height adjustment capability, allowing the platform to be raised or lowered to match different vehicle heights and jack positions. This dynamic adjustment feature enables the same jack stand structure to adapt to various vehicle types and jack configurations while maintaining structural simplicity.
3Device complexity
If the jack stand requires placement away from the jacking location, then the support structure can be simplified, but vehicle stability and safety are compromised
Solution Approach 1:
By merging the jack stand support structure with the jack location, the design eliminates the need for separate support positions. The hollow body configuration allows the jack stand to be positioned exactly where the jack operates, providing stable vehicle support while maintaining structural simplicity through the integrated design rather than requiring complex positioning mechanisms.

AI summary
A jack stand for a vehicle includes a plurality of walls joined together to form a body, the body being hollow. A base is formed by lower edges of the walls and a top surface joins top edges of the walls. One of the walls includes a wall opening and the top includes a top opening, the wall opening and the top opening extending towards one another, meeting proximate the top edge of one of the walls, thereby forming a single, continuous opening extending from the top into one of the walls.
