Rotating Pin Multifunctional Plug for Universal Power Standards
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The varying national and regional power plug and socket standards across countries make it difficult to use electrical appliances in different regions, as commonly used plugs are not compatible with foreign sockets.
Innovation Solution
A multifunctional plug with a rotating pin piece and conductive contact system that allows for interchangeable connections with different plug standards, enabling the pin to extend into and conduct with other plug assemblies, and a power adapter that integrates this plug for universal compatibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single fixed plug design is used, then the structure is simple and easy to manufacture, but the adaptability to different national and regional power standards is poor
Solution Approach 1:
The pin piece is designed to be rotatable relative to the main body, allowing it to change its spatial orientation and configuration. This dynamic element enables the plug to adapt to different socket standards by rotating the pin piece to appropriate angles, transforming a static single-function plug into a dynamic multi-function device.
Solution Approach 2:
The plug integrates multiple functions into a single device by combining a main body with a multi-positioned pin piece. The pin piece can be positioned in different configurations to match various national and regional power standards, making one plug universally applicable across different countries and regions without needing multiple separate plugs.
2Adaptability or versatility
If multiple separate plugs are used for different regions, then each plug can be optimized for its specific standard, but the device complexity increases and portability decreases
Solution Approach 1:
Multiple plug functions that would normally require separate physical plugs are merged into a single integrated device. The main body houses a pin piece that can be configured in multiple positions, effectively combining what would be several different plugs into one unified device, reducing the quantity from multiple separate plugs to a single multi-functional plug.
Solution Approach 2:
The plug achieves universal applicability by incorporating a pin piece that can assume different configurations corresponding to various national and regional power standards. This allows a single plug to replace multiple region-specific plugs, enabling users to travel internationally with just one plug device.
3Adaptability or versatility
If the pin piece is made rotatable to achieve multi-position connection, then the adaptability improves, but the reliability of electrical connection may be affected
Solution Approach 1:
The pin piece incorporates a rotatable mechanism that allows it to dynamically adjust its position while maintaining reliable electrical contact. The rotation capability enables adaptation to different socket orientations while the design ensures that once positioned, the connection remains stable and reliable for the duration of use.
