Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Collapsible frame structures that rely on elastic cords for assembly are often cumbersome and limited in load-bearing capacity.
Innovation Solution
A collapsible support frame with segmented legs pivotally connected to a collar, held together by an elastic cord, allowing for easy folding and deployment, with leg segments seating within the collar to maintain structural integrity and prevent separation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If frame members are held together by an elastic cord, then assembly is facilitated, but the structure becomes cumbersome and load-bearing capacity is limited
Solution Approach 1:
A collar acts as an intermediary component that receives and secures multiple leg segments. The collar provides a centralized attachment point where leg segments can be connected through pivotable joints, replacing the need for complex cord-based connections while maintaining ease of assembly.
Solution Approach 2:
The legs are divided into multiple separable segments that can be independently assembled and connected to the collar. This segmentation allows the frame to be easily disassembled for storage while maintaining structural integrity when assembled, resolving the contradiction between ease of operation and strength.
2Volume of moving object
If leg segments are separable for storage, then compact storage is achieved, but leg segments may become lost or separated
Solution Approach 1:
Multiple leg segments are merged into a single assembly unit by connecting them to the central collar through pivotable joints. This merging ensures that all segments remain attached to each other via the collar, preventing loss or separation while maintaining compact storage capability.
Solution Approach 2:
The pivotable joints allow the leg segments to dynamically transition between folded and deployed positions. When folded, segments are compact; when deployed, they automatically assume their load-bearing positions, ensuring reliability throughout the transformation process.
3Adaptability or versatility
If legs are pivotally connected to collar, then folding and deployment are enabled, but structural complexity increases
Solution Approach 1:
The collar serves multiple functions: it acts as a central connection point for leg segments, provides pivotable joints for folding/deployment, and maintains structural integrity during transformation. This multi-functionality reduces the need for additional specialized components, thereby limiting the increase in structural complexity.

Function Achieved in This Case
Facilitates compact storage and efficient load-bearing capacity while preventing leg segments from becoming lost or separated, enhancing assembly and stability.
Implementation Method 1
The elastic cord provides tension that keeps the leg segments together in the deployed position, and prevents the leg segments from becoming lost or separated in the folded position

AI summary
A collapsible support frame includes a plurality of segmented legs pivotally connected to an inner surface of a collar, and are held together by an elastic cord. The legs pivot between a folded position and an deployed position. In the folded position, the legs segments form a bundle to facilitate storage or transport. Portions of the legs segments may seat within leg seats formed in the outer surface of the collar. In the deployed position, the legs pivot to contact leg support seats formed at angles in an inner surface of the collar. After contact, each leg extends in a different direction supported by its respective leg support seat. The elastic cord provides tension that keeps the leg segments together in the deployed position, and prevents the leg segments from becoming lost or separated in the folded position.
