Electrical Connector With Cable Winding Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electric cables are difficult to wind due to their tendency to twist and turn, making it challenging to achieve good windings in applications such as electrical appliances, extension cords, and electric vehicle recharging cables.
Innovation Solution
The electrical connector incorporates means for temporarily fastening cables, including rotatable plates with circular notches, a housing with a spring-actuated slider, a cylindrical ring with hinged closure, and holder means like laces or tapes with self-gripping strips, to facilitate cable management and winding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If cable winding is attempted without fastening means, then the cable can be freely moved and handled, but the cable twists and turns making winding difficult and deteriorating quickly
Solution Approach 1:
The fastening means are activated before the winding process to secure the cable in a controlled position. The notched plates or cylindrical ring with closure means temporarily fasten the cable, preventing it from twisting or turning during the winding operation, thereby enabling smooth winding while maintaining cable integrity
Solution Approach 2:
The fastening means act as an intermediary device between the cable and the winding operation. By introducing this intermediate fastening mechanism, the cable is temporarily secured to the connector body, allowing the winding process to proceed without the cable interfering or deteriorating
2Ease of operation
If fastening means are added to the connector, then cable winding becomes easier and more secure, but the device complexity increases
Solution Approach 1:
The fastening means are designed as separate, modular components (notched plates or cylindrical ring with closure means) that can be integrated into the connector body. This segmentation allows the fastening function to be added without completely redesigning the connector, thereby managing complexity while providing the desired cable winding assistance
3Ease of operation
If the notched plates are designed with large circular arc angles, then the cable can be more easily inserted and looped, but the closure security may be reduced
Solution Approach 1:
The notched plates feature localized circular arc notches with specific geometric properties optimized for cable insertion, while the rest of the plate structure maintains rigidity and closure security. The circular arc geometry provides a smooth guiding surface for cable insertion, while the overall plate design ensures secure fastening when closed
