Foldable Frame Supporting Assembly for Stability Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing foldable frames lack stability when in use, which is a significant issue for applications such as foldable beds and tables.
Innovation Solution
The design incorporates pivotally connected mounting and leg assemblies with supporting assemblies that control rotation and provide additional support to ensure stability when the frame is unfolded, utilizing a combination of pivotally and rotatably connected members and linkages to maintain structural integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a simple foldable frame structure is used, then ease of manufacture and portability are improved, but stability when in use deteriorates
Solution Approach 1:
The frame is divided into multiple independent leg assemblies (first, second, and third leg assemblies) that can be separately manufactured and assembled. Each leg assembly includes distinct components (mounting assemblies, supporting assemblies, lateral bars, legs) that can be produced independently, simplifying manufacturing while maintaining overall structural stability when assembled together.
Solution Approach 2:
The frame incorporates dynamic elements including pivotally connected mounting assemblies that allow rotation, and supporting assemblies with controllers that can selectively move along members to adjust and control the rotation of leg assemblies. This dynamic capability enables the frame to adapt to different usage states (folded vs. unfolded) while maintaining stability when in use.
2Ease of operation
If pivotally connected mounting and leg assemblies are used to enable folding, then portability and ease of operation are improved, but structural stability deteriorates
Solution Approach 1:
The supporting assemblies act as intermediary elements between the pivotally connected mounting assemblies and leg assemblies. These supporting assemblies include controllers that selectively move along members to control the rotation of leg assemblies, providing stability during operation while maintaining the ease of folding through pivotal connections.
Solution Approach 2:
The frame utilizes parameter changes in the form of selective movement of controllers along members of the supporting assemblies. This allows control over the rotation parameters of the leg assemblies, enabling the frame to transition between folded and unfolded states while maintaining structural stability during use through controlled parameter adjustment.

AI summary
A frame includes first and second mounting assemblies pivotally connected with each other. The frame also includes first, second and third leg assemblies. The first leg assembly is pivotally connected the first mounting assembly. The second leg assembly is pivotally connected with the second mounting assembly. The third leg assembly is pivotally connected with both of the first and second mounting assemblies. The frame further includes one or more supporting assemblies to enhance stability of the frame. A supporting assembly includes first, second and third members and a controller. The first member is connected with the third leg assembly. The controller is connected with the first member and selectively movable along the first member. The second member is pivotally connected with the controller and the first mounting assembly, and the third member is pivotally connected with the controller and the second mounting assembly.
