Foldable Power Supply With Perpendicular Pivoting Axis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing foldable sockets cannot be used vertically due to parallel rotation shaft direction, causing plug or transformer interference when trying to use them in different orientations.
Innovation Solution
A foldable power supply device with a pivoting unit between two sockets, where the rotation shaft direction is not parallel to the plugging holes, allowing for both block-type and vertical configurations, enabling plugs or transformers to be inserted in two face-to-face directions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the rotation shaft direction is parallel to the plugging direction of the sockets, then the foldable socket can be closed or opened to any angle, but all plugs can merely be plugged into the plugging holes in the same direction causing interference
Solution Approach 1:
The patent changes the rotation shaft direction from being parallel to the plugging direction to being perpendicular to it. This dimensional change allows plugs to be inserted in two face-to-face directions when the device is folded, eliminating plug interference while maintaining foldability.
2Length of stationary object
If the foldable power supply device is opened to become a block type, then the height is lowered and it can be used as a multi-hole type, but it occupies more space
Solution Approach 1:
The patent employs a foldable structure with a pivoting connection that allows the device to dynamically change between an opened block type configuration (lower height, multi-hole usage) and a folded vertical type configuration (compact footprint). This dynamic adaptability resolves the contradiction between height reduction and space occupation.
3Area of stationary object
If the foldable power supply device is folded to become a vertical type, then one side can align with the wall and space is saved, but plugs or transformers may interfere with each other
Solution Approach 1:
The patent uses asymmetric orientation of plugging holes on the two sockets. When folded vertically, the plugging holes are positioned at different orientations relative to the wall, allowing plugs to be inserted in two face-to-face directions without interference, while maintaining the compact vertical footprint.

AI summary
A foldable power supply device includes a first socket, a second socket, and a pivoting unit. The first socket has multiple sets of first plugging holes and first conductive plates. The second socket has multiple sets of second plugging holes and second conductive plates. The pivoting unit is located between the first socket and the second socket. The direction of the rotation shaft of the pivoting unit is not parallel to the plugging direction of the first plugging holes and the second plugging holes. Thereby, the foldable power supply device can be opened into a block type to lower its height and be used as a multi-hole type. Alternatively, the device can also be folded to become a vertical type so that one side of the device can align with the wall, and the plugs or the transformers can be plugged into the device in two face-to-face directions.
