Retractable Extension Socket with Winding Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional outlets lack versatility and tend to create a cluttered appearance due to the lack of proper fixation of the socket body, conducting wire, and plug, limiting their usage modes and portability.
Innovation Solution
A retractable extension socket design featuring a socket body with a fixing structure, a receiving structure, and a conducting wire connected to a plug, allowing the outlet to be used as both an extension socket and a single plug, with the ability to wind the wire around the socket body for easy carrying.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the outlet is designed as a fixed extension socket, then it provides stable power transmission, but it cannot be used in other modes and creates a cluttered appearance
Solution Approach 1:
The outlet is designed with dual functionality: it can be used as a traditional extension socket or as a single plug by winding the conducting wire around the socket body and attaching the plug into the fixing structure. This multi-functionality directly addresses the versatility improvement while the integrated design keeps the structure manageable
Solution Approach 2:
The plug can be stored within the socket body when not in use, and the conducting wire can be wound around the socket body. This nesting arrangement reduces clutter and improves appearance while maintaining adaptability between different usage modes
2Ease of operation
If the conducting wire and plug are left loose, then the outlet can be easily assembled, but they create a cluttered appearance and are not properly fixed
Solution Approach 1:
The plug is designed to be stored within the socket body when not in use, creating a neat, clutter-free appearance. The conducting wire can be wound around the socket body and secured, eliminating loose wires while maintaining easy assembly through the integrated receiving structure
Solution Approach 2:
The receiving structure acts as an intermediary between the plug and socket body, providing a designated storage location that keeps the plug secure and neat when not in use, thereby improving appearance without complicating assembly
3Ease of operation
If the outlet is designed for portability, then it can be easily carried around, but the components must be properly fixed to avoid clutter
Solution Approach 1:
The fixing structure enables the outlet to function as a single plug when portability is needed, while the same structure ensures secure component fixation during transport. The dual functionality addresses both portability and reliability requirements
Solution Approach 2:
The plug and conducting wire are integrated into the socket body through nesting arrangements, ensuring they remain securely fixed during transport while maintaining portability. The receiving structure keeps the plug nested within the socket body, preventing clutter and ensuring reliable component fixation

AI summary
A retractable extension socket includes an socket body, a fixing structure, a receiving structure, a conducting wire and a plug. The fixing structure and the receiving structure are disposed on the socket body. One end of the conducting wire is connected to the socket body. The plug is connected to the other end of the conducting wire. Thus, a retractable extension socket is formed. The retractable extension socket can be used as an extension socket. In addition, by winding the cable into the socket body and attaching the plug into the fixing structure, the retractable extension socket can be used as a single plug. Furthermore, the plug can be collected into the receiving structure in order that it can be carried around easily.
