Universal Socket Polarity Correction via Segmented Electrode Assemblies
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Universal sockets fail to correctly connect the polarities of multinational plugs, leading to a risk of electric leakage and interference, as they often insert the neutral pin into the live electrode plate and vice versa, which can cause safety issues and precision instrument interference.
Innovation Solution
A universal socket with polarity correction featuring a cover, wedging body, and shell design that includes specific electrode holes and wedging members to ensure correct polarity alignment, using elastic members to secure the pins and prevent incorrect insertion, and a ground electrode plate assembly to prevent electric leakage and interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a universal socket is designed to accept multiple plug types, then the adaptability of the socket is improved, but the polarity connection reliability deteriorates due to incorrect pin-to-electrode alignment
Solution Approach 1:
The socket is divided into multiple electrode assemblies (first and second neutral electrode assemblies, first and second live wire electrode assemblies) with distinct structural configurations. Each assembly is designed to accommodate specific plug types, allowing the socket to segment the connection pathways according to plug geometry, thereby ensuring correct polarity alignment for each plug type while maintaining multi-country compatibility
Solution Approach 2:
The patent employs asymmetric electrode plate configurations where neutral electrode plates and live wire electrode plates have different structural arrangements. The first and second neutral electrode assemblies differ from the first and second live wire electrode assemblies in their electrode plate layouts, creating asymmetric connection pathways that guide pins to the correct electrode polarity based on the plug's physical structure
2Ease of operation
If the socket structure is simplified to accommodate various plugs, then the ease of operation is improved, but the precision of polarity alignment deteriorates leading to electric leakage risks
Solution Approach 1:
The electrode plates are pre-configured in specific positions within their respective assemblies before the plug is inserted. The neutral electrode plates and live wire electrode plates are arranged in advance according to different plug type requirements, so that when the plug is inserted, the pins automatically align with the pre-positioned electrodes of the correct polarity, ensuring precise alignment without requiring complex real-time adjustment mechanisms
