Outdoor Power Socket Structure with Pivotal Axes for Line Entanglement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Outdoor extension line power sockets often cause power line entanglement and damage due to repetitive rotations when users move electric products, leading to potential fractures in the internal conductive lines.
Innovation Solution
A power socket structure that rotates with the power plug, featuring a socket body with pivotal axes and blockers, a fixation case with recess positioning parts, and a cone for stable outdoor positioning, ensuring the socket always faces the electric product and allowing controlled rotation to prevent entanglement and damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the power socket is fixedly placed at a certain location, then the socket body maintains stable position, but the power line becomes entangled and damaged due to repetitive rotations when the electric product is moved
Solution Approach 1:
The socket body is designed to rotate dynamically along with the power plug instead of remaining fixed. The pivotal connection structure enables the socket body to follow the rotation of the power plug, preventing the power line from becoming entangled or damaged while maintaining operational stability.
2Reliability
If the socket body rotates with the power plug, then the power line entanglement is prevented, but the socket body requires complex pivotal connection structures
Solution Approach 1:
The pivotal connection structure is divided into two independent pivotal axes: the first pivotal axis connects the socket body to the power plug, allowing rotation in one direction, while the second pivotal axis connects the socket body to the power line, allowing rotation in the opposite direction. This segmentation simplifies the overall structure by distributing the rotation functions across separate axes.
3Adaptability or versatility
If the first pivotal axis allows free rotation, then the socket body can follow the power plug rotation, but the socket body may rotate excessively causing instability
Solution Approach 1:
Blockers are installed on the first pivotal axis to prevent the socket body from rotating beyond a certain angle. These blockers provide preliminary resistance against excessive rotation, ensuring the socket body follows the power plug rotation within a safe range while preventing unstable over-rotation.
4Reliability
If the second pivotal axis is designed for power line connection, then the power line can be electrically connected, but the power line may still become entangled during rotation
Solution Approach 1:
The second pivotal axis enables the socket body to rotate in the opposite direction to the power plug rotation, dynamically compensating for the power line's movement. This opposite rotation prevents the power line from becoming entangled while maintaining the electrical connection between the socket body and the power line.

AI summary
A power socket structure for outdoor electric extension line is disclosed, comprising one or more power sockets, a socket body including a first pivotal axis and a second pivotal axis, a fixation case and a cone, wherein the cone is fixedly combined with at least a sidewall of the fixation case, and the socket body is pivotally connected onto the fixation case such that the socket body can rotate within the fixation case. Upon inserting a power plug of an electric product into the power socket, the power plug can bring the socket body to rotate within the fixation case so that the power socket of the socket body always faces towards the electric product thereby preventing the product power line of the power plug from wrapping around the socket body which may otherwise cause troublesome power line entanglements.
