Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional extension outlet-sockets have fixed jack directions, leading to reduced utilization due to size and shape limitations of plugs with rectifier transformers, and pose safety hazards when plugs need to be twisted or bent for insertion, causing potential electrical fires.
Innovation Solution
A rotational outlet-socket with multiple units capable of independent angular rotation, featuring a pivotally connected electric conduction member group that allows each outlet-socket unit to adjust its angle to accommodate different plug sizes and orientations, preventing wire damage and improving utilization efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional extension outlet-socket with fixed jack directions is used, then the structure is simple and easy to manufacture, but the utilization ratio is reduced when plugs with rectifier transformers or large sizes are inserted, and safety hazards occur when plugs need to be twisted or bent for insertion
Solution Approach 1:
The outlet-socket unit is designed with rotational capability around a central axis, transforming from a fixed static structure to a dynamic adjustable one. Each outlet-socket unit can rotate independently to different angles (0°, 45°, 90°, 135°, 180°, etc.) to adapt to plug orientations, solving the contradiction between fixed structure and plug compatibility.
Solution Approach 2:
The extension outlet-socket is divided into multiple independent outlet-socket units (e.g., five units) that can rotate independently. Each unit is separated by spacing rings and can be adjusted individually, allowing the system to accommodate multiple plugs with different orientations simultaneously while maintaining structural simplicity.
2Reliability
If the outlet-socket unit rotates to accommodate different plug directions, then wire damage is prevented and safety is improved, but the structural complexity increases due to the pivotal connection mechanism
Solution Approach 1:
The electric conduction member group (including first electric conduction rod, second electric conduction rod, and ground wire electric conduction rod with clamping portions) is designed as an integrated pivoting assembly. When the outlet-socket unit rotates, the entire conduction group rotates together around the central axis, maintaining electrical connection integrity while accommodating plug orientation changes, thus improving safety without requiring complex individual wire routing mechanisms.
Solution Approach 2:
The pivotal connection is specifically designed at the ground wire clamping portion, which serves as the rotation axis. This localized pivot point allows the outlet-socket unit to rotate while maintaining stable electrical connections through the clamping portions, concentrating the rotational mechanism at a single point rather than distributing complexity throughout the entire electrical connection system.
3Productivity
If multiple outlet-socket units are arranged in series, then the utilization ratio is improved by accommodating multiple plugs, but the device complexity increases due to the need for spacing rings and embedding slot portions
Solution Approach 1:
Multiple outlet-socket units are nested along a central axis within a compact housing structure. The units are arranged in series with spacing rings that fit between them, creating a space-efficient configuration that maximizes the number of outlets in a limited volume while maintaining rotational freedom for each unit.
Solution Approach 2:
The spacing rings serve multiple functions: they separate individual outlet-socket units to prevent interference during rotation, provide structural support for the series arrangement, and facilitate the embedding of conduction member groups. This multi-functional design increases outlet capacity without proportionally increasing overall structural complexity.

AI summary
A rotational outlet-socket includes an outlet-socket group including at least two outlet-socket units connected in series, and each outlet-socket unit separately performing rotation in a plurality of angles, where an electric conduction member group is disposed in the outlet-socket unit and includes a first electric conduction rod including a first clamping portion, a second electric conduction rod including a second clamping portion, and a ground wire electric conduction rod including a ground wire clamping portion, and the ground wire clamping portion is pivotally connected to and pivots around the ground wire electric conduction rod through a pivotal connection portion by using a pivotal connection piece. The ground wire clamping portion pivots around a rotation axis between the first clamping portion and the second clamping portion when the outlet-socket unit rotates.
