Adjustable Leg Assembly for Stable Tables on Uneven Terrain
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional support structures, such as sawhorses and tables, are prone to instability and wobbling on uneven terrain due to their static design, posing safety hazards and inefficiencies in portability and storage.
Innovation Solution
An adjustable support assembly featuring rotatable legs with leg exchange brackets that allow for differential elevation adjustment and secure locking, enabling stable support on varying terrain and easy storage and transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional static support legs are used, then the structure is simple and easy to manufacture, but the structure becomes unstable on uneven terrain
Solution Approach 1:
The patent applies the dynamics principle by transforming static support legs into adjustable legs that can dynamically adapt to uneven terrain. Each leg is equipped with an adjustment mechanism allowing independent length modification, enabling the structure to accommodate variable ground conditions and maintain stability without requiring a completely complex redesign of the overall structure.
2Adaptability or versatility
If adjustable legs are added to provide terrain adaptation, then the structure becomes stable on uneven ground, but the device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the support structure into independent adjustable leg units, each with its own adjustment mechanism. This allows terrain adaptation capability to be added to individual legs rather than requiring a complex integrated system, reducing overall device complexity while maintaining adaptability across uneven surfaces.
3Strength
If static sawhorse design is used, then the structure is robust and strong, but it is cumbersome for portability and storage
Solution Approach 1:
The patent applies dynamics by enabling the sawhorse legs to be collapsed or adjusted to compact positions, transforming the structure from a fixed, space-consuming form to a dynamic, compact configuration for storage and transport, while maintaining structural robustness when deployed.
4Ease of operation
If telescoping or folding legs are used to improve portability, then the structure becomes easier to store, but stability and ease of use are compromised
Solution Approach 1:
The patent applies segmentation by using discrete adjustable leg units with independent adjustment mechanisms rather than integrated telescoping or folding systems. This segmentation allows each leg to be independently optimized for both compact storage and stable support, avoiding the stability compromises inherent in conventional telescoping designs.

AI summary
An adjustable assembly with at least a pair of adjustable legs is used to stabilize a support element on a wide range of terrains. Each of the adjustable legs is engaged with a leg exchange bracket 13 that is adapted for and connected to a support element such as a sawhorse beam, a tabletop, or other leg-bearing support element. Each of the adjustable legs can be variably adjusted to adapt to height and other terrain surface variations so as to provide an essentially steady and generally level support surface. Once the desired adjustment is selected, the legs are locked. If the terrain changes or there is a need to transfer the support surface to another terrain, the legs can be readily unlocked, the position of one or more legs adjusted, and the lock(s) reengaged to provide a steady and generally level assembly on the changed terrain. The assembly can also be configured so that it can be reversibly engaged with a variety of work surfaces either by removal of the full assembly from the support surface, or removal of the legs from their respective leg exchange brackets. An assembly can be readily disengaged from a first support surface, and reengaged with a second support surface. The legs of the assembly are easily adjusted to allow for stacking and for ease of transport of the support surface.
