Rotatable Plug Structure for Flexible Insertion and Wire Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing plugs with fixed pins are prone to wire stock damage and breakage due to improper insertion, leading to safety hazards, reduced durability, and poor user experience.
Innovation Solution
A rotatable plug design with a base and plug portion that allows the pins to rotate relative to the base, featuring annular metal conductors and a rotating shaft, enabling flexible insertion into sockets without damaging the wire stock.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the plug pins are fixed relative to the housing, then the plug structure is simple and stable, but the wire stock rotates or bends during insertion which damages and breaks the wire stock
Solution Approach 1:
The patent applies the dynamics principle by making the plug portion rotatable relative to the base through a rotating shaft mechanism. This allows the plug pins to dynamically adjust their orientation during insertion, preventing wire stock damage while maintaining structural simplicity. The rotating shaft enables controlled movement without complicating the overall plug structure.
2Ease of operation
If the plug pins are fixed relative to the housing, then the manufacturing process is simple, but the plug cannot be inserted in any direction which reduces ease of operation
Solution Approach 1:
The rotating shaft mechanism enables the plug portion to rotate freely relative to the base, allowing users to insert the plug in any direction without complex adjustments. This dynamic capability provides insertion flexibility while keeping the structure simple through the use of a straightforward rotating connection.
3Object-affected harmful factors
If the plug pins are fixed relative to the housing, then the plug structure is stable, but the wire stock bends to a certain extent during insertion which causes safety hazards
Solution Approach 1:
The rotating shaft mechanism dynamically adjusts the plug pins' orientation during insertion, preventing wire stock from bending or rotating excessively. This eliminates safety hazards associated with wire damage while maintaining a simple plug structure through the efficient rotating connection design.
