360-Degree Rotatable Plug for Cable Damage Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional plugs are prone to damage and electrical instability due to the need to twist connecting cables, leading to issues like leakage and short circuits, which compromises both electrical performance and convenience.
Innovation Solution
A rotatable plug design featuring an upper cover, dynamic rotatable unit, static rotatable unit, connecting cable, and lower cover, allowing for 360-degree rotation along the traction direction of the cable, ensuring the cable remains connected and undamaged.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the plug is inserted into a socket and the electronic equipment is moved, then the use convenience is improved, but the connecting cable is easily damaged and broken down causing electrical performance instability
Solution Approach 1:
The patent introduces a rotatable structure that allows the plug body to rotate 360 degrees along the traction direction of the connecting cable. This dynamic mechanism enables the cable to move freely without twisting or bending excessively, resolving the contradiction between ease of operation (moving the equipment) and reliability (preventing cable damage). The rotatable unit includes a rotating plate, rotating column, and bearing structure that facilitates smooth rotation while maintaining electrical connection stability.
2Ease of operation
If the connecting cable is twisted to accommodate equipment movement, then the ease of operation is improved, but the connecting cable is easily damaged leading to leakage and short circuit
Solution Approach 1:
The rotatable plug body provides a dynamic solution that replaces cable twisting with structured rotation. The bearing and rotating column mechanism allows controlled rotation without subjecting the cable to harmful twisting forces, thus improving ease of operation while eliminating the harmful factor of cable damage and electrical hazards.
Solution Approach 2:
The patent introduces an intermediary rotatable mechanism between the plug body and the connecting cable. This intermediary structure (comprising the rotating plate, rotating column, and bearing) absorbs and manages the movement stress, preventing it from being transmitted to the cable as damaging twist forces, thereby protecting the cable from damage while maintaining operational convenience.

AI summary
A rotatable plug includes an upper cover, a dynamic rotatable unit, a static rotatable unit pivotally mounted to a bottom of the dynamic rotatable unit, a connecting cable fastened to the static rotatable unit, and a lower cover. The dynamic rotatable unit includes a plurality of dynamic conductive tubes of which each has a rotatable ring. The static rotatable unit includes a plurality of static conductive tubes of which each has a ring body. The rotatable ring is disposed around and is electrically connected with the ring body. The upper cover, the static rotatable unit and the lower cover are capable of rotating 360 degrees along a traction direction of the connecting cable, and the upper cover, the static rotatable unit, the lower cover and the connecting cable are capable of proceeding the same angle rotation.
