Dual-Arm Child Glider Structure for Stable Low-Roll Motion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Infant swings and gliders often cause discomfort due to rolling motion and lack of stability, with support frames either being unstable or too large for convenient use.
Innovation Solution
A child motion device with a compact, stable support frame that provides a side-to-side gliding motion with minimal rolling, featuring a base portion, upright portion, and pivotally connected swing arms to generate a gliding motion, allowing for adjustable orientations and entertainment features like display panels and electronic controls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single arm is pivotally mounted to support the child receiving receptacle, then the device can provide swinging motion, but it introduces significant rolling motion that causes discomfort
Solution Approach 1:
The support structure is divided into multiple arms (first and second swing arms) instead of a single arm. Each arm is pivotally mounted to the support frame at different locations, creating a segmented configuration that distributes the motion and reduces harmful rolling effects on the child support portion.
Solution Approach 2:
The swing arms are positioned asymmetrically relative to each other, with the first swing arm pivotally mounted at a first location and the second swing arm pivotally mounted at a second location that is offset from the first location. This asymmetric arrangement creates a more stable motion pattern that minimizes rolling.
2Stability of the object's composition
If the support frame is designed to provide stability, then the device becomes stable, but the footprint size becomes too large for convenient use
Solution Approach 1:
The first and second swing arms are coupled together at a coupling point that is positioned between their respective pivot locations. This merging of the two arms into a coupled configuration creates structural stability while maintaining a compact footprint, as the coupled arrangement efficiently distributes loads without requiring a large base area.
Solution Approach 2:
The coupling of the swing arms creates a three-dimensional structural configuration that provides stability in multiple directions simultaneously. The coupled arms form a spatial arrangement that resists tipping and rolling forces without requiring a large horizontal footprint, effectively using vertical and diagonal support elements to achieve stability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device reduces child discomfort by minimizing rolling motion and providing a stable, compact, and versatile gliding motion, suitable for various orientations and easy mobility, while maintaining stability and entertainment options.
Implementation Method 1
a pair of swing arms having first ends pivotally coupled to the upright portion of the support frame and second ends coupled to the child support portion. A pivoting side-to-side motion of the pair of swing arms generates a gliding side-to-side motion of the child support portion.

AI summary
A child motion device including a support frame, a frame hub coupled to the support frame, a gliding swing mechanism pivotally mounted to the frame hub, and a cantilevered child support portion pivotally mounted to the gliding swing mechanism. In example embodiments, the child support portion can be in the form of a child seat or a bassinet. In example embodiments, the child support portion can be oriented between multiple seat-facing orientations for providing either of a side-to-side gliding movement or a front-to-back gliding movement.
