Infant Swing Frame Layout for Stability and Hand Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Infant swings with driving modules and battery assemblies configured at connecting devices compromise stability and lack protection guards, raising the center of gravity and exposing infants to potential harm from hanging arms.
Innovation Solution
The infant swing design includes a frame body with pivoting front and rear leg frames, a seat assembly, a driving module at the pivot, protection guards between the leg frames to prevent harm, and a battery assembly positioned at the bottom to lower the center of gravity and enhance stability, along with skidproof foot assemblies for stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the driving module and battery assembly are configured at the connecting devices, then the functional mechanism is integrated, but the center of gravity is raised and stability decreases
Solution Approach 1:
The battery assembly is repositioned from the upper connecting devices to the lower leg frames, changing the spatial dimension of component placement. This dimensional relocation moves heavy components downward, lowering the center of gravity while maintaining functional integration through proper structural connection.
2Device complexity
If protection guards are not installed, then the structure is simple, but infants are exposed to harmful factors from hanging arms
Solution Approach 1:
Protection guards are introduced as intermediary safety components between the hanging arms and the infant. These guards act as a protective barrier that prevents direct contact between the infant and potentially harmful moving parts, while maintaining relative structural simplicity through straightforward guard design.
3Stability of the object's composition
If the battery assembly is positioned at the bottom of the frame body, then the center of gravity is lowered and stability is improved, but the electrical connection to the driving module becomes more complex
Solution Approach 1:
The battery assembly is extracted from the upper connecting devices and placed in the lower leg frames, separating the power source from the driving mechanism's immediate vicinity. This extraction allows for independent optimization of stability (through lower positioning) while electrical connections are managed through dedicated wiring channels or flexible connectors.

AI summary
Infant swing has a front leg frame and a rear leg frame pivoting to each other and connecting to a seat assembly via a driving module at the pivot between the front leg frame and the rear leg frame for swinging the seat back and forth. Two protection guards are mounted and connected between the front leg frame and the rear leg frame for preventing the toddler from being harmed when reaching his/her hands out between the frame and the seat as the toddler sits in the seat and swings relative to the frame. A battery assembly that provides power for the driving module is configured at the bottom of the frame for effectively lowering the center of gravity of the infant swing and providing higher stability. Skidproof foot assemblies mounting at the elbows of the front leg frame and the rear leg frame can further provide stability and integrity.
