Collapsible Infant Swing Seat Structure for Compact Folding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current infant swings are cumbersome due to large standing frames and complicated folding mechanisms, making them difficult to transport.
Innovation Solution
A collapsible child motion apparatus with a base, seat, and upright column, featuring pivotally connected frame segments and a magnetic drive system for easy assembly and disassembly, allowing the seat to sway sideways for soothing children while compactly folding for transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If large standing frames and swing arms are used to provide stable support for the child, then the structural stability is improved, but the device complexity and ease of operation deteriorate due to complicated folding mechanisms
Solution Approach 1:
The frame is divided into multiple collapsible segments including side bars, seat support bars, and swing arm segments that can fold relative to each other. This segmentation allows the stable large-frame structure to be broken down into compact sections for easy storage and transport while maintaining structural integrity during use
Solution Approach 2:
The frame incorporates dynamic folding joints and pivot points that allow the structure to transition between expanded stable configuration and collapsed compact configuration. The side bars and seat support bars are designed with movable connections that enable smooth transformation while maintaining stability in the operational state
2Strength
If large standing frames are used to support the seat, then the load-bearing capacity is improved, but the ease of operation worsens due to difficulty in folding and disassembly
Solution Approach 1:
The load-bearing frame is segmented into collapsible sections with defined folding joints. The side bars, seat support bars, and swing arms are divided into segments that can be easily folded while maintaining sufficient load-bearing capacity through proper joint design and structural geometry
Solution Approach 2:
Folding joints and connection mechanisms serve as intermediaries between the load-bearing requirements and the ease of assembly/disassembly requirements. These joints allow the structure to maintain strength during use while enabling simple folding operations for storage and transport
3Adaptability or versatility
If the seat is pivotally connected at the rear end of the bottom frame segment, then the swing motion function is improved, but the ease of operation deteriorates due to complicated folding requirements
Solution Approach 1:
The seat assembly is segmented from the frame structure with a pivotal connection at the rear end of the bottom frame segment. This segmentation allows the seat to swing independently while the frame segments can be folded for storage, combining swing functionality with ease of assembly and disassembly
Solution Approach 2:
The pivotal connection between the seat and the bottom frame segment creates a dynamic swing motion capability. This dynamic connection allows the seat to move freely for soothing the child while the rest of the frame can be statically folded for compact storage when not in use

AI summary
A child motion apparatus includes a base (102), a seat (104) arranged above the base (102), and an upright column (106) disposed below the seat (104). The seat (104) includes a bottom frame segment (114) and a seatback frame segment (116), the bottom frame segment (114) having a front (102B,104A,104B) and a rear end (114A), the seatback frame segment (116) being pivotally connected with the rear end (114A) of the bottom frame segment (114). The upright column (106) pivotally supports the seat (104) above the base (102), and is connected with the bottom frame segment (114) at a location between the front end (114A,114B) and the rear end (114A) thereof.
