Swing Seat Assembly Rotating Support Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing swing seat assemblies lack a reliable mechanism for rotating the seat relative to a stationary support structure, limiting user flexibility and comfort in changing orientations.
Innovation Solution
A support portion comprising a pair of rotatably coupled support bars, with a bolt assembly allowing 180-degree rotation between the lower and upper support bars, facilitated by elongate cables connecting the seat to both bars and a stationary structure, enabling secure and adjustable positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed support structure is used, then structural stability is maintained, but rotation capability is lost
Solution Approach 1:
The support structure transitions from a static fixed connection to a dynamic rotatable joint. The lower support bar is rotatably coupled to the upper support bar through a bolt assembly that allows rotational movement while maintaining structural integrity. This enables the swing seat to rotate between different orientations (e.g., 180 degrees) while the bolt assembly maintains secure coupling throughout the rotation.
2Adaptability or versatility
If a rotatable joint is added, then rotation capability is enabled, but device complexity increases
Solution Approach 1:
The support structure is divided into separate components: an upper support bar, a lower support bar, and a bolt assembly. The rotatable joint is created by coupling these segments together, allowing rotation while keeping each component relatively simple in design. This segmentation enables the rotation function without requiring a completely complex mechanism.
3Reliability
If secure coupling is maintained during rotation, then structural integrity is preserved, but ease of operation is reduced
Solution Approach 1:
The bolt assembly acts as an intermediary mechanism between the upper and lower support bars. It provides secure coupling that maintains structural integrity during rotation, while also serving as a mediator that allows controlled rotational movement. The bolt assembly can be positioned at different locations along the support bars to adjust the rotation characteristics and ease of operation.

AI summary
A swing seat assembly, including a seat portion and a support portion, a lower support bar and an upper support bar, a lower set of elongate cables having first ends coupled with the lower support bar and second ends coupled with the seat portion, and an upper set of elongate cables having first ends coupled with a stationary support structure and second ends coupled with the upper support bar. The lower support bar is rotatably coupled with the upper support bar.
