Rigid Frame Swing Structure for Adult-Child Safety and Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing swings often have complex structures with many moving parts, which can lead to injuries from catching loose clothing or body parts, and are supported by chains that complicate the design and make it difficult for adults to get in and out of the seat.
Innovation Solution
A swing design featuring a rigid frame with a bent tubular structure that reduces the number of moving parts and eliminates the need for chains, allowing for easy adult access and minimizing the risk of injury by positioning the frame's intermediate portion below the adult's eye level for secure holding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If chains are used to connect seats to support structure, then the swing can be suspended and moved, but the risk of catching loose clothing or body parts increases and the structure becomes more complex
Solution Approach 1:
The patent removes chains entirely from the design. Instead of using chains to connect the adult seat and child seat to the support structure, the invention uses a rigid frame with integrated attachment points that directly connect to the support structure, eliminating the intermediate chain components that pose safety hazards.
Solution Approach 2:
The rigid frame acts as an intermediary structure between the support structure and the seats. Rather than using flexible chains, the rigid frame provides a stable, chain-free connection mechanism that maintains structural integrity while eliminating the pinching hazard associated with chain-link connections.
2Adaptability or versatility
If many moving parts are included in the swing design, then the swing can provide various functions and adjustments, but the risk of catching loose clothing or body parts increases
Solution Approach 1:
The swing is divided into distinct functional segments: a rigid frame structure, an adult seat, and a child seat, each with fixed connections. This segmentation eliminates the need for moving adjustment parts while maintaining the ability to provide different seating configurations for adults and children.
Solution Approach 2:
Instead of designing a swing with many adjustable moving parts that require mechanisms for modification, the invention inverts the approach by creating a fixed, rigid structure where adaptability is achieved through the configuration of fixed elements rather than movable ones. The rigid frame with integrated seat attachments provides functionality without requiring adjustment mechanisms.
3Ease of operation
If the adult seat is positioned low for easy access, then adults can easily get in and out, but the swing structure requires higher support points for stability
Solution Approach 1:
The rigid frame is designed with a multi-dimensional configuration where the seat attachment points are positioned at optimal heights for stability, while the adult seat itself is accessible from ground level. The frame extends upward to provide stable support points while the seating area remains accessible, resolving the contradiction through spatial arrangement in multiple dimensions.

AI summary
A swing comprising an adult seat and a child seat, said two seats connected together via a common frame and arranged such that the two seats face each other. The common frame comprises a rigid frame, said rigid frame having a first portion, a middle portion and a second portion, said middle portion being arranged between the first and second portions. The swing is arranged to be suspended from the first portion. The adult seat is attached to the second portion. The child seat is attached to the middle portion. In this way a simple construction is provided which is safe and easy to use for both adults and children.
