Rotatable Detachable Plug for Power Converters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional power converters with protruded plugs often interfere with surrounding objects and obstruct socket holes due to fixed plugging directions, making it difficult to plug or unplug them from sockets, especially when traveling to countries with different socket standards.
Innovation Solution
An electronic device with a detachable plug that allows the plugging direction to be changed by rotating the plug, featuring a plug body with four trenches and conductive terminals with L-shaped connection and extension portions, enabling the plug to be assembled in various orientations for improved space utilization and adaptability to different socket standards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the plug is protruded from the main body in a fixed direction, then the power converter can be connected to the socket, but the power converter may interfere with surrounding objects and obstruct socket holes, making it difficult to plug or unplug
Solution Approach 1:
The plug is designed to be rotatable relative to the main body through a bearing structure, allowing the plugging direction to be dynamically adjusted. The rotation mechanism includes a plug body, main body, and bearing that enables the plug to change its orientation from a fixed protruding position to multiple rotational positions, thereby avoiding interference with surrounding objects and facilitating easier plugging and unplugging operations.
2Adaptability or versatility
If the plug has a fixed structure, then the manufacturing is simple, but the plugging direction cannot be changed to adapt to different socket standards
Solution Approach 1:
The plug incorporates a rotatable connection mechanism with a bearing that allows the plug body to rotate relative to the main body. This dynamic structure enables the plug to adapt to different socket standards by changing its plugging direction, while the bearing provides a relatively simple mechanical implementation compared to more complex adjustable mechanisms.
3Adaptability or versatility
If the plug is detachable with rotation capability, then the plugging direction can be changed, but the assembly and disassembly process may cause damage
Solution Approach 1:
The bearing structure provides a smooth rotational interface between the plug body and main body, reducing friction and mechanical stress during assembly and disassembly operations. This dynamic rotation capability allows for controlled movement that minimizes the risk of damage compared to forced detachment of rigid connections.
Solution Approach 2:
The bearing structure acts as a cushioning element that absorbs and distributes mechanical stresses during assembly and disassembly. By providing a compliant rotational interface, the bearing prevents concentrated forces that could cause damage to the plug or main body during the detachable operations.

AI summary
An electronic device with a detachable plug capable of changing plugging direction is disclosed. The electronic device comprises a main body and a plug. The main body has a plug-receiving portion, and the plug-receiving portion comprises at least two conducting pieces. The plug has a plug body and at least two conductive terminals. The plug body comprises four trenches disposed at a bottom thereof and arranged as a square. Each of the conductive terminals comprises a plugging portion, a connection portion and an extension portion, wherein the plugging portion is protruded out of a surface of the plug body, and the connection portion and the extension portion are embedded in the plug body and are corresponding to two adjacent trenches, respectively. Thereby, when the plug is assembled on the plug-receiving portion of the main body, the two conducting pieces are respectively received in two opposite trenches and contacted with either the two connection portions or the two extension portions of the two conductive terminals for power conduction.
