Collapsible Swing Frame with Cross-Brace for Rigidity and Portability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing collapsible infant swing frames lack structural rigidity and stability when unfolded for use and are difficult to transport or move within a living space.
Innovation Solution
A collapsible swing frame design featuring first and second supports with a cross-brace pivotally coupled between them, providing stability and allowing the frame to move between expanded and collapsed configurations, along with wheeled base hubs for improved portability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a collapsible support frame is used for compact storage and transport, then portability is improved, but structural rigidity and stability deteriorate
Solution Approach 1:
The support frame is divided into multiple collapsible sections with pivot joints, allowing the frame to be segmented into foldable units. This enables the frame to collapse into a compact configuration for portability while maintaining structural integrity when expanded for use.
Solution Approach 2:
The frame incorporates dynamic elements including pivot joints and locking mechanisms that allow the structure to transition between collapsed and expanded states. The cross-brace with locking mechanism provides dynamic stability, locking into place when expanded to ensure rigidity during use while allowing collapse when unlocked.
2Volume of moving object
If the frame is made collapsible for compact storage, then storage space is reduced, but structural stability when unfolded deteriorates
Solution Approach 1:
The collapsible frame sections are designed to nest within each other when collapsed, with the cross-brace and support members folding into a compact nested configuration. This minimizes storage volume while the locking mechanism ensures that when expanded, the nested sections form a stable, rigid structure.
Solution Approach 2:
The frame utilizes composite construction combining rigid materials for the support members with flexible connection elements. The cross-brace and support frame are made from materials that provide both structural strength when assembled and flexibility for collapsing, achieving a balance between storage compactness and operational stability.

AI summary
A collapsible swing frame for supporting a child receiving receptacle includes first and second support members, and upper swing mechanism, and a cross-brace pivotally coupled between the first and second support members. Preferably, the collapsible swing frame is movable between an expanded configuration and a collapsed configuration. Preferably, the cross-brace provides a rigid and substantially supportive connection between the first and second support members.
