Foldable Frame with Outwardly Slanted Legs for Enhanced Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing foldable tables with vertical legs are often unstable and difficult to fold and unfold, making them inconvenient to use.
Innovation Solution
The design incorporates a frame with pivotally coupled leg assemblies that are rotatable between a use position and a storage position, featuring outwardly slanted legs to enhance stability and a mounting assembly with supporting assemblies to control rotation and stabilization, allowing for easier folding and unfolding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If vertical legs are used in foldable tables, then the structure is simple, but the stability is poor
Solution Approach 1:
The patent applies asymmetry by designing legs that slant outward at specific angles rather than being vertical. The first and second legs of each leg assembly slant outward at a first angle, while when in use position, they slant outward at a second angle. This asymmetric angular design expands the supporting area and significantly improves table stability while maintaining structural simplicity.
2Ease of operation
If foldable mechanism is added to enable folding, then the convenience is improved, but the difficulty to fold and unfold increases
Solution Approach 1:
The patent applies dynamics by making the leg assemblies rotatable relative to the mounting assembly between use position and storage position. The leg assemblies are pivotally coupled and can rotate, allowing the table to transition between folded and unfolded states. This dynamic design enables easy folding and unfolding while maintaining stability when in use position.
Solution Approach 2:
The patent applies parameter changes by varying the angles of the legs at different positions. The first and second legs slant outward at a first angle when folded, and at a second angle when in use position. This parameter change optimizes both the folded compactness and the unfolded stability, making the folding mechanism more efficient and easier to operate.
3Stability of the object's composition
If outwardly slanted legs are used, then the stability is enhanced, but the supporting area needs to be expanded
Solution Approach 1:
The patent applies asymmetry by designing the leg assemblies with specific outward slant angles. The first and second legs of each assembly slant outward at a first angle, and when in use position, they slant outward at a second angle. This asymmetric angular configuration naturally expands the supporting area while enhancing frame stability through the widened base.

AI summary
A foldable frame with enhanced stability includes a mounting assembly, a first leg assembly and a second leg assembly. Each of the first and second leg assemblies are pivotally coupled with the mounting assembly and rotatable with respect to the mounting assembly between a use position and a storage position. Each of the first and second leg assemblies includes a substantially straight first leg and a substantially straight second leg. The first and second legs are slanted outwardly to increase the supporting area and thus enhance the stability of the foldable frame and stability of other structures supported by the foldable frame.
