Adjustable Power Socket With Rotating Hollow Sleeves
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional power sockets with fixed plug orientations are inefficient due to varying sizes and shapes of rectification transformers, leading to reduced availability and increased risk of electrocution from dust exposure and improper plug alignment, especially when trying to accommodate three-tabbed plugs.
Innovation Solution
A power supply with adjustable plug insertion direction, comprising multiple hollow sleeves and conductive modules with clamping parts, allowing rotation of plug holes to align with different clamping parts for flexible plug insertion without moving the internal conductor, thus enhancing usability and reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional power socket with fixed plug holes is used, then the structure is simple and easy to manufacture, but the availability decreases when rectification transformers with large volumes cover neighboring plug holes
Solution Approach 1:
The hollow sleeves are designed to be rotatable around the conductive modules, allowing the plug holes to dynamically change orientation. This enables users to adjust the plug insertion direction to accommodate different plug types and sizes, resolving the contradiction between fixed structure and adaptability.
2Adaptability or versatility
If a rotation socket is used to increase availability, then more plug orientations are possible, but three-tabbed plugs cannot be plugged in due to the two-holed plug hole structure
Solution Approach 1:
The power socket is divided into separate functional components: conductive modules that remain stationary and hollow sleeves that rotate. The plug holes are integrated into the hollow sleeves rather than being fixed to the conductive modules, allowing independent rotation of the sleeve to achieve three-tabbed plug compatibility while maintaining structural simplicity.
3Reliability
If traditional exposure design of power socket is used, then the structure is simple, but the power socket cannot shelter or insulate the plug holes not in use, decreasing life time and increasing electrocution risk
Solution Approach 1:
The hollow sleeves serve multiple functions: they provide the plug holes for electrical connection, enable rotation for different plug orientations, and act as protective covers for the conductive modules. When plugs are not in use, the hollow sleeves shelter the plug holes, preventing dust ingress and reducing electrocution risk, thus achieving protection without additional complex structures.

AI summary
The present invention discloses a power supply including a first conductive module, a second conductive module connected to the first conductive module, and a plurality of hollow sleeves. The first conductive module and the second conductive module respectively include a plurality of first clamping parts and second clamping parts, wherein a position of each second clamping part corresponds to one of first clamping parts. The hollow sleeves are housing around the first conductive module and the second conductive module. Each hollow sleeve includes at least one plug hole, and covers one of the first clamping parts and the corresponding second clamping part. When rotating the hollow sleeve, the plug hole selectively coincides with the first clamping part or the second clamping part, so that multiple fins of a plug are inserted into the first clamping part or the second clamping part through the plug hole.
