Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional power plugs are prone to causing twisted power cords when inserted into sockets, especially in tight spaces, leading to potential damage and safety hazards due to torsional stress, and often have poor contact quality.
Innovation Solution
A rotatable electrical plug design featuring a non-rotating and rotating assembly with a housing and frame, where the rotating assembly can pivot 360 degrees, incorporating ring-shaped conductors and a fastening element to secure the conductive unit, ensuring stable and durable electrical connectivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the power plug is fixedly connected with the power cord, then the structure is simple and stable, but the power cord becomes twisted and prone to damage when inserted into tight spaces
Solution Approach 1:
The patent applies the dynamics principle by making the plug body rotatable relative to the power cord through a bearing structure. The plug body can rotate 360 degrees around the power cord axis, allowing the power cord to remain stationary while the plug body orients itself for insertion. This dynamic mechanism eliminates cord twisting and torsional stress during insertion operations.
2Ease of operation
If the power plug can rotate to facilitate insertion, then ease of operation improves, but contact quality deteriorates
Solution Approach 1:
The patent segments the plug structure into two independent parts: a stationary power cord connection portion and a rotatable plug body portion. The power cord connects to the base which remains fixed, while the plug body with contact pins rotates independently on the bearing. This segmentation ensures that rotation occurs only in the plug body, maintaining stable electrical contact at the cord-plug interface while enabling rotational movement for insertion convenience.
3Object-affected harmful factors
If the plug body rotates relative to the power cord, then cord damage is prevented, but the device complexity increases
Solution Approach 1:
The patent introduces a bearing as an intermediary component between the power cord connection base and the plug body. This bearing enables smooth rotational movement while maintaining structural integrity and electrical insulation. The bearing acts as a mediator that facilitates rotation without requiring complex mechanical linkages or additional control mechanisms, thus minimizing the increase in device complexity while achieving cord damage prevention.
