Solution Overview

Problem

Traditional receptacles often face issues where the short interval between fixed electrical outlets or large-volume/power plug shapes prevent simultaneous use, leading to inconvenience in plugging multiple plugs.

Innovation Solution

A freely rotatable electrical conduction structure comprising cylindrical portions with arc contact terminals that allow rotation while maintaining contact, formed through injection molding with an insulated material, enabling flexible use and preventing obstruction from large or uniquely shaped plugs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If receptacles are fixed and arranged in line with short intervals, then the structure is simple and manufacturing is easy, but multiple plugs cannot be used simultaneously due to obstruction

Engineering Contradiction:

Improvesimultaneous use of multiple plugsVSAvoidreceptacle arrangement structure

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent applies the dynamics principle by making the receptacle body rotatable around a central axis. The receptacle can rotate 360 degrees freely, transforming from a static fixed position to a dynamic movable position. This allows users to adjust the receptacle orientation to avoid obstruction from large or uniquely shaped plugs, enabling simultaneous use of multiple plugs without changing the overall compact structure.

Inventive Principle:

Principle #15Dynamics

2Ease of operation

If receptacles are arranged with larger intervals to allow simultaneous use, then multiple plugs can be used at the same time, but the device size and space occupation increase

Engineering Contradiction:

Improvesimultaneous use of multiple plugsVSAvoidspace occupation of receptacle

Core Design Contradiction:

Ease of operationVSArea of stationary object

Solution Approach 1:

By implementing rotatable receptacles, the patent maintains a compact overall structure with short intervals between receptacles, yet achieves the functionality of larger spacing through dynamic repositioning. Each receptacle can rotate independently to optimize its position, effectively using space without increasing the footprint of the entire device.

Inventive Principle:

Principle #15Dynamics

3Adaptability or versatility

If receptacles are made rotatable to improve flexibility, then multiple plugs can be used simultaneously, but the structural complexity and manufacturing difficulty increase

Engineering Contradiction:

Improveflexibility of receptacle useVSAvoidmanufacturing of rotatable structure

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The rotatable structure is designed with a central axis and support columns that provide a straightforward mechanical rotation mechanism. The receptacle body is connected to the support column through a simple rotational joint, allowing 360-degree rotation without complex mechanisms. This design achieves high adaptability while keeping the manufacturing process relatively simple and the structure easy to understand and produce.

AI summary

The present invention provides a freely rotatable electrical conduction structure including at least two cylindrical electrical conduction portions, an insulated material portion and at least two electrical conduction terminals. The at least two cylindrical electrical conduction portions are arranged separately along an axis, wherein the inner surface of each cylindrical electrical conduction portion is welded with an end of a conducting wire. The insulated material portion is combined with the at least two cylindrical electrical conduction portions via injection molding to form a circular shaft assembly. The at least two electrical conduction terminals correspond to the at least two cylindrical electrical conduction portions respectively, and each electrical conduction terminal partially projects to form an arc contact portion configured to abut onto the outer peripheral surface of its corresponding cylindrical electrical conduction portion. Each electrical conduction terminal is allowed to rotate around its corresponding cylindrical electrical conduction portion with its arc contact portion keeping contacting and conducting with the outer peripheral surface.
