Rotating Power Plug for Multi-Standard Socket Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Power converters require multiple adapters to function with different international wall socket standards, making it inconvenient for users to connect them across various countries.
Innovation Solution
A power plug design featuring an insulating housing, rotating axles, plug pins, and a rotating ring that allows for conversion between different standards by sliding a serrated strip, driving the plug pins to rotate between an eight-shape and parallel state, enabling compatibility with multiple socket types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a power converter uses a fixed plug design, then it can be reliably connected to a specific wall socket standard, but it cannot be used in countries with different socket standards without additional adapters
Solution Approach 1:
The plug pins are designed to be rotatable relative to the insulating housing through rotating axles, allowing the plug to dynamically change its configuration between different standards (e.g., American parallel configuration and Australian eight-shape configuration). This dynamic adjustment eliminates the need for multiple fixed adapters.
Solution Approach 2:
The single power plug is designed to perform multiple functions by supporting different plug standards through rotation. The plug can be configured to match both American and Australian wall socket standards, making one device universally compatible with multiple countries' electrical infrastructures.
2Adaptability or versatility
If multiple adapters are used to support different wall socket standards, then compatibility with various countries is achieved, but the ease of operation deteriorates due to the need to attach and detach adapters
Solution Approach 1:
The rotating mechanism allows users to easily switch between different plug standards by simply rotating the plug pins, eliminating the cumbersome process of attaching and detaching multiple adapters. The sliding strip with serrated teeth provides a simple manual rotation interface.
3Adaptability or versatility
If the plug pins are made rotatable to achieve different standards, then adaptability improves, but the device complexity increases due to additional rotating components
Solution Approach 1:
The plug is segmented into functional components: the insulating housing, the rotating axles, the plug pins, and the sliding strip mechanism. This segmentation allows each component to have a specific function while working together to achieve the overall goal of multi-standard compatibility.
Solution Approach 2:
The rotating axles are nested within the insulating housing, and the sliding strip is positioned between the top and bottom covers. The compact nested arrangement minimizes the overall device size while incorporating the necessary rotating mechanism for standard conversion.

AI summary
A power plug includes an insulating housing in which a receiving barrel is crossed, top and bottom covers covering top and bottom ends of the receiving barrel, a sliding strip slidably located between the top and bottom covers with serrated sliding teeth protruding on two opposite sides thereof, two rotating axles located at two sides of the sliding strip with rotating teeth protruding on two relative insides thereof and meshed with the sliding teeth, two plug pins vertically integrated in the rotating axles and a rotating ring sheathing outside the receiving barrel with two pushing blocks protruding at an inside wall thereof. The pushing blocks project into the receiving barrel and are against two ends of the sliding strip to push the sliding strip to slide by rotating the rotating ring so as to drive the rotating axles together with the plug pins to rotate relatively.
