Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional telescopically adjustable chargers have complex adjustment structures, making them inconvenient for production, installation, and use.
Innovation Solution
A retractable data cable design featuring a hollow housing with a winding assembly and movable assembly, where the winding assembly includes a rotatable winder, a transmission assembly, and an auxiliary member that provides a preload force for elastic deformation, allowing the cable to be freely stretched or retracted, and includes a coil spring for stored elastic potential energy to improve retraction functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional telescopically adjustable charger structure is used, then cable length adjustment is achieved, but the adjustment structure becomes too complicated
Solution Approach 1:
The cable management system is divided into distinct functional modules: a winding assembly for cable storage, a transmission assembly with gear mechanisms for controlled deployment, and a movable assembly with auxiliary members for positioning. Each module performs a specific function, simplifying the overall design while maintaining adjustment capability.
Solution Approach 2:
The cable is wound around the winding assembly, which is nested within the housing. The transmission assembly and movable assembly are arranged within the housing, with the auxiliary member disposed within the transmission assembly. This nested arrangement compactly integrates multiple components without increasing external dimensions.
2Ease of manufacture
If the adjustment structure is simplified, then ease of manufacture and installation is improved, but cable positioning precision may be compromised
Solution Approach 1:
The auxiliary member is coupled with the transmission assembly to provide a preload force for the swing reset member to swing toward or away from the side of the auxiliary member. This self-generated preload force ensures reliable gear engagement and cable positioning without requiring additional external mechanisms, simplifying manufacturing while maintaining precision.
Solution Approach 2:
The swing reset member includes a first cooperating unit coupled with the position-limiting gear, a second cooperating unit coupled with the moving gear, and a third cooperating unit coupled with the auxiliary member. The curved or angled surfaces of these cooperating units enable smooth engagement and disengagement, ensuring precise cable positioning through simple mechanical contact.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design simplifies the adjustment structure, enhances practicability, and improves the retractable function of the data cable by allowing easy length adjustment and secure locking, while also being easier to install and maintain.
Implementation Method 1
The auxiliary member is disposed on one side of the transmission assembly and coupled with the transmission assembly. The winder rotates to drive the transmission assembly to move and then drive the auxiliary member to produce elastic deformation, so as to provide the transmission assembly with a preload force for swinging toward or away from the side of the auxiliary member.
Implementation Method 2
the winding assembly further includes a coil spring disposed on the side of the winder away from the movable assembly and fixedly connected to the winder

AI summary
A retractable data cable assembly is provided, which includes a cable, a winding assembly, a movable assembly and a housing defining an accommodating cavity where the winding assembly and the movable assembly are arranged. The cable is wound around the winding assembly and exposed out of the housing. The winding assembly includes a winder rotatable with respect to the housing. The movable assembly is disposed on a side of the winder and positioned to connect to the housing. The movable assembly includes a transmission assembly and an auxiliary member respectively coupled with the winder and the transmission assembly. The auxiliary member produces elastic deformation to provide the transmission assembly with a preload force for swinging toward or away from the side of the auxiliary member. The storage of the retractable data cable assembly is more convenient.
