Multi-Fold Foldable Frame with Nested Subsections for Compact Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing foldable frames are often bulky when folded, requiring large storage and transport spaces, and are fixed in size when unfolded, unable to accommodate different user needs or preferences.
Innovation Solution
The development of pivoting/locking mechanisms, foldable frames, and frame assemblies that can be folded multiple times, allowing for compact storage and easy transportation, and can be easily connected or detached to meet various user needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the foldable frame is designed to fold only in half, then the structure is simple, but the storage and transport space required is large
Solution Approach 1:
The foldable frame is divided into multiple subsections (first front subsection, second front subsection, first rear subsection, second rear subsection) that can be folded independently at multiple locations, enabling the frame to be folded into quarters or eighths rather than just in half, significantly reducing storage volume
Solution Approach 2:
When folded, the subsections are arranged in a nested configuration where the first front subsection and first rear subsection are disposed between the second front subsection and second rear subsection, allowing the frame to compact into a much smaller volume
2Stability of the object's composition
If the foldable frame is designed with fixed size when unfolded, then the structure is stable, but it cannot accommodate different user needs or preferences
Solution Approach 1:
The frame incorporates pivoting connections at multiple locations (front section pivotally connected to middle support, rear section pivotally connected to middle support, subsections pivotally connected to each other) that allow the frame to be configured in different sizes when unfolded while maintaining stability through locking mechanisms
Solution Approach 2:
The frame can be configured to provide different sizes to meet different needs or preferences of different users, and can also be detached to form separate smaller frames, making it versatile for multiple applications
3Device complexity
If the foldable frame lacks a locking mechanism, then the structure is simple, but accidental folding cannot be prevented
Solution Approach 1:
The locking mechanism is designed to automatically engage and lock the subsections in their unfolded position through the pivoting/locking mechanism, preventing accidental folding without requiring continuous user attention or complex control systems

AI summary
A foldable frame includes a front section, a rear section, a front support, a rear support, and a middle support. The front section includes a first front subsection and a second front subsection foldable relative to each other, and the rear section includes a first rear subsection and a second rear subsection foldable relative to each other. The front support is pivotally connected to the first front subsection, and the rear support is pivotally connected to the first rear subsection. The second front subsection and second rear subsection are pivotally connected to the middle support. When folded, the first front and rear subsections are disposed between the second front and rear subsections, with the front support disposed between the first and second front subsections and the rear support disposed between the first and second rear subsections.
