Infant Swing Foot-Mounted Power Supply for Compact Folding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional infant swings face design challenges when integrating a power supply device, as it often requires additional space in the driving hub, affecting flexibility and increasing the volume, which compromises the swing's structural design and aesthetics.
Innovation Solution
The power supply device is integrated onto a foot of the infant swing using a carrier, first and second feet, a pivotal positioning mechanism, and a driving device, allowing the power supply to be positioned on the pivot base without occupying extra space in the driving hub, thus maintaining compactness and flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the power supply device is disposed in the driving hub, then the infant swing can achieve swinging function, but the volume of the driving hub increases and the structural design flexibility is reduced
Solution Approach 1:
The power supply device is extracted from the driving hub and relocated to the foot assembly. Specifically, the power supply device is disposed on the first foot or second foot, separate from the driving hub, thereby reducing the driving hub volume and maintaining structural design flexibility while still providing power for the swinging function.
Solution Approach 2:
Instead of placing the power supply device within the horizontal space of the driving hub, the invention relocates it to the vertical extension - the foot assembly. This dimensional relocation allows the power supply device to be positioned in an underutilized space, reducing interference with the driving hub's internal layout and maintaining overall compactness.
2Ease of manufacture
If the power supply device is disposed in the driving hub, then the infant swing can achieve swinging function, but the look of the infant swing is affected
Solution Approach 1:
The power supply device is extracted from the visually prominent driving hub area and relocated to the foot assembly, which is less visible when the infant swing is in use. This extraction maintains the compact appearance and aesthetic design while still providing the necessary power supply function.
3Volume of stationary object
If the power supply device is disposed on the foot, then the compact appearance and flexibility are maintained, but additional space is required on the foot structure
Solution Approach 1:
The power supply device is merged with the foot assembly by disposing it on the first foot or second foot, utilizing the existing foot structure as the mounting platform. This integration approach maintains overall compactness while incorporating the power supply function into the foot assembly without requiring completely separate structural elements.

AI summary
An infant swing (10) includes a carrier (12), a first foot (14), at least one arm (16), a second foot (18), a pivotal positioning mechanism (24), a driving device (20), and a power supply device (22). The arm (16) is connected to the first foot (14) and the carrier (12). A second pivot base (30) of the second foot (18) is pivotally connected to a first pivot base (28) of the first foot (14) . The second foot (18) is used for supporting the carrier (12) on a holding surface (26) cooperatively with the first foot (14) and the arm (16). The pivotal positioning mechanism (24) is disposed between the first pivot base (28) and the second pivot base (30). The pivotal positioning mechanism (24) is used for constraining rotation of the second foot (18). The driving device (20) is used for driving the arm (16). The power supply device (22) is used for providing electric power to the driving device (20) so as to make the carrier (12) capable of swinging relative to the first foot (14).
