Solution Overview
Problem
Existing anti-misplug safety sockets with sliding plates have complex structures, frequent interference, high manufacturing costs, and cannot cover various models like 20-ampere sockets.
Innovation Solution
An anti-misplug safety socket design using a bottom shell and surface cover with oblique sliding grooves and a moving plate, where sliding blocks and elastic reset mechanisms ensure stable and efficient plugging, and a blocking mechanism prevents movement, utilizing a single moving plate for conductive connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If two sliding plates are used to prevent misplug, then misplug prevention is achieved, but the structure becomes complex and manufacturing cost increases
Solution Approach 1:
The patent merges the functions of two separate sliding plates into a single integrated moving plate with through holes. This moving plate simultaneously guides both plug pole pieces and prevents misplug, eliminating the need for two separate sliding plates while maintaining safety functionality. The moving plate is positioned between the two jack assemblies and works in coordination with safety gates on both sides.
Solution Approach 2:
The single moving plate performs multiple functions: it guides the plug pole pieces during insertion, prevents misplug by blocking incorrect orientations, coordinates with safety gates on both sides, and maintains structural integrity for both jack assemblies. This multi-functional design reduces component count and simplifies the overall structure while achieving reliable misplug prevention.
2Device complexity
If a single moving plate is used instead of two sliding plates, then structure is simplified and manufacturing cost is reduced, but misplug prevention capability must be maintained
Solution Approach 1:
The single moving plate integrates the misplug prevention functionality that was previously distributed across two separate sliding plates. The through holes in the moving plate guide the plug pole pieces while the plate itself acts as a barrier against misplug, maintaining safety functionality with reduced structural complexity.
Solution Approach 2:
The moving plate serves as a universal component that works with both jack assemblies simultaneously, providing misplug prevention for both sides while simplifying the overall structure. This single component replaces two separate sliding plates and their associated reset mechanisms, reducing manufacturing complexity while maintaining comprehensive misplug protection.
