Infant Swing Power Layout for Space and Water Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional infant swings face space constraints and design inflexibility due to integrating power supply devices within the driving hub, which can lead to water exposure and electrical leakage, compromising the appearance and functionality.
Innovation Solution
Separate disposition of the driving device and power supply device, where the power supply is placed on a leg assembly electrically connected to the driving device, reducing structural occupancy and elevating it above the bearing surface to prevent water exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the power supply device is disposed in the driving hub, then the power supply can be integrated with the driving mechanism, but the occupied space of the driving hub increases and structural design flexibility is reduced
Solution Approach 1:
The patent divides the infant swing into separate functional modules: the driving hub containing only the motor and driving components, and the leg assembly containing the power supply device. This segmentation allows each module to be optimized independently, maintaining integration benefits while preserving design flexibility in other areas of the swing structure.
2Device complexity
If the power supply device is disposed in the driving hub, then integration is achieved, but the power supply device may be exposed to water and electrical leakage may occur
Solution Approach 1:
The power supply device is extracted from the driving hub and relocated to the leg assembly. This extraction removes the electrical components from the area most susceptible to water exposure (near the bearing surface), thereby preventing electrical leakage while maintaining a compact integrated design through proper spatial arrangement.
3Reliability
If the power supply device is disposed separately on the leg assembly, then protection from water is improved, but the structural configuration becomes more complex
Solution Approach 1:
While the power supply device is separated from the driving hub for protection, the patent merges the power supply structure with the leg assembly framework. The power supply is positioned within the leg assembly's structural boundaries, combining two functions (support and power housing) into one integrated structural element, thereby reducing overall structural complexity despite the functional separation.

AI summary
An infant swing (10) includes a support frame (12), a holding frame (14), a driving device (16), and a power supply device (18). The support frame (12) includes a first connecting port (20), a second connecting port (22), and a leg assembly (23). Two ends of the leg assembly (23) are connected to the first connecting port (20) and the second connecting port (22). The holding frame (14) is pivoted to the first connecting port (20) and the second connecting port (22). The driving device (16) is disposed on the first connecting port (20) for driving the holding frame (14) to swing relative to the support frame (12). The power supply device (18) is disposed on the leg assembly (23) and is electrically connected to the driving device (16). The power supply device (18) is used for providing the driving device (16) with power for driving the holding frame (14).
