Plug With Integrated Rotating Pull Portion for Easy Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing plug designs face challenges in reducing spatial waste, ensuring safety, and facilitating easy removal while maintaining a compact form, often requiring additional components that increase costs and risk breakage under pulling force.
Innovation Solution
A plug with an integrated body and pull portion, where the pull portion is unitarily connected to the body through a connecting portion, allowing it to tilt and provide a protruding step for easy gripping and removal without increasing the plug's size, using a resilient material for enhanced usability and cost-effectiveness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the socket has a sunken hole and the plug is nearly completely embedded, then spatial waste is reduced and safety is improved, but the plug becomes difficult to pull out
Solution Approach 1:
The pull portion is designed to rotate from a first position (parallel to the second lateral surface) to a second position (perpendicular to the body), transforming from a compact state to an extended gripping state. This dynamic transformation allows the plug to maintain a low profile during normal use while enabling easy removal when needed.
Solution Approach 2:
The pull portion extends in a direction perpendicular to the lateral surfaces of the body, utilizing the third dimension (depth) rather than increasing the footprint area. This allows the gripping surface to be positioned away from the socket face without increasing the plug's width or depth occupation when not in use.
2Ease of operation
If a pull ring is added to facilitate plug removal, then ease of operation is improved, but device complexity and cost increase
Solution Approach 1:
The pull portion is unitarily connected to the body, forming an integrated structure without separate components like traditional pull rings. This merging of functions reduces the number of parts, simplifies assembly, and lowers manufacturing costs while maintaining the ease of removal function.
Solution Approach 2:
The pull portion serves dual functions: it acts as both the gripping surface for removal and as a structural element integrated into the plug body. The unitary connection provides both structural support and the mechanical linkage needed for removal, eliminating the need for separate fastening mechanisms.
3Ease of operation
If a rotating pull ring is used to provide gripping surface, then ease of operation is improved, but reliability decreases due to potential breakage
Solution Approach 1:
By integrating the pull portion and body as a single unitary structure, the weak point of the rotating connection (rotating shaft or supporting portion) is eliminated. The integrated design ensures that the pull portion and body move as one, distributing stress throughout the entire structure rather than concentrating it at a small rotating joint.
Solution Approach 2:
The plug is made from resilient material that combines flexibility and strength, allowing the integrated structure to withstand pulling forces without breaking. The material properties compensate for the reduced size of the connecting portion, maintaining reliability while enabling the compact design.
4Ease of operation
If a lever is attached to the socket surface for easy removal, then ease of operation is improved, but it obstructs other jacks and is inconvenient to use
Solution Approach 1:
Instead of extending the gripping surface laterally (increasing width) or attaching a lever to the socket face (increasing surface obstruction), the pull portion extends in the depth direction from the plug body. This positions the gripping surface in the third dimension, away from the socket face, without increasing the plug's footprint or obstructing adjacent jacks.

AI summary
A plug, comprises a body (1) having a first lateral surface (15) and a second lateral surface (11) which are opposite to each other; a plurality of pins (3) arranged on the first lateral surface (15); wherein a pull portion (2) is arranged on the second lateral surface (11) of the body (1); the pull portion (2) is unitarily connected to the body (1), and the pull portion (2) can be turned over in the direction away from the first and second lateral surfaces (15,11) under the action of an external force. Compared with the prior art, the connecting portion and the body are formed integrally, so that later assembly procedure is saved, the manpower cost is reduced, and the production efficiency is high.
