Infant Swing Leg-Mounted Power Supply for Hub Space Relief
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional infant swings face design constraints due to the need to accommodate both the driving and power supply devices within the same hub, leading to increased space occupation and reduced structural flexibility, as well as potential exposure to water and electrical risks.
Innovation Solution
The power supply device is relocated to the leg assembly, which is electrically connected to the driving device, allowing for separate placement and reducing the occupied space within the hub, thus enhancing design flexibility and protecting the power supply from water exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the power supply device is disposed in the driving hub, then the infant swing can be powered, 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 functional modules: the driving hub contains only the driving device (motor), while the power supply device is separated and disposed on the leg assembly. This segmentation allows each component to be optimized independently and enables greater structural design flexibility.
Solution Approach 2:
The power supply device is extracted from the driving hub and relocated to the leg assembly. This extraction reduces the space occupation within the driving hub and eliminates the constraint that previously limited structural design flexibility.
2Reliability
If the power supply device is disposed in the driving hub, then the infant swing can be powered, but the driving hub requires extra containing space
Solution Approach 1:
The power supply device is extracted from the driving hub and relocated to the leg assembly. This extraction directly reduces the volume and space occupation of the driving hub, allowing for a more compact and efficiently designed driving mechanism.
3Reliability
If the power supply device is disposed in the driving hub, then the infant swing can be powered, but the configuration of other components in the driving hub is affected
Solution Approach 1:
The patent segments the power supply system from the driving mechanism by placing the power supply device on the leg assembly rather than in the driving hub. This segmentation simplifies the driving hub's component configuration, allowing for more straightforward assembly and maintenance.

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