Pivot-Bracket Leg Assembly for Self-Leveling Tables on Uneven Surfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing self-leveling platforms face challenges in maintaining stability on uneven surfaces and require leg assemblies that can be folded for space-efficient transportation and storage.
Innovation Solution
The development of foldable leg assemblies with rotatable bracket assemblies and pivot devices that allow for self-leveling on uneven surfaces, featuring a stem and flange receiving region, and a leg receiving portion to accommodate multiple legs, enabling the platforms to be collapsed for easier handling and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If triangular pivoting leg assemblies are used for self-leveling platforms, then the platform can maintain stability on uneven surfaces, but the device occupies excessive space and is difficult to transport and store
Solution Approach 1:
The leg assembly is divided into multiple sections that can pivot relative to each other. The leg is segmented into an upper section and a lower section connected by a pivot mechanism, allowing the leg to be folded into a compact configuration for transport while maintaining its full extended length for stable platform support on uneven surfaces.
Solution Approach 2:
The leg assembly incorporates dynamic pivot joints that allow the leg to adapt its configuration between extended and folded states. The pivot mechanism enables the leg to automatically adjust its angle and position to maintain platform levelness on uneven ground, while also allowing manual folding for compact storage and transportation.
2Reliability
If fixed leg assemblies are used to maintain platform levelness on uneven surfaces, then stability is improved, but the device cannot be easily collapsed for transportation and storage
Solution Approach 1:
The leg assembly uses dynamic pivot joints that allow automatic adjustment to maintain platform levelness on uneven surfaces. The same pivot mechanism enables easy manual folding for transport, providing both automatic stability adjustment and manual collapsibility without requiring separate mechanisms.
Solution Approach 2:
The pivot mechanism is designed to automatically adjust the leg angle and position in response to uneven surface conditions, self-regulating to maintain platform levelness without user intervention. This self-adjusting capability works seamlessly with the manual folding function for easy transport.
3Strength
If traditional support structures are used, then the platform can be supported, but they are not adjustable for maintaining level position on uneven surfaces
Solution Approach 1:
The support structure replaces fixed traditional legs with dynamic pivot-mounted legs that can automatically adjust their angle and position. This allows the strong support capability of traditional structures to be maintained while adding the adaptability to self-adjust for uneven surface conditions and maintain platform levelness.
