Anti-loose Data Cable with Nested Protective Layers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional data cables are prone to breakage and have unreliable connections, especially with the positioning head detaching easily, and they often cannot support flashing custom ROMs or are costly due to expensive integrated circuits.
Innovation Solution
An anti-loose data cable design featuring multiple protective fixing layers made from polypropylene, acrylonitrile butadiene styrene, and thermoplastic elastomers, which are injection molded to securely integrate the USB cable and interface element, preventing detachment and enhancing durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional data cable structures are used, then manufacturing is simple, but the positioning head and rotary head break easily and connections are unreliable
Solution Approach 1:
The protective fixing layer is divided into multiple segments (first protective fixing layer, second protective fixing layer, third protective fixing layer) that are sequentially assembled around the interface element and USB cable. Each layer provides specific protective functions, with the first layer securing the connection, the second layer providing structural support, and the third layer offering external protection. This segmentation allows the positioning head to be firmly fixed without requiring a completely complex redesign of the entire cable structure.
Solution Approach 2:
The patent implements a nested structure where the first protective fixing layer is placed inside the second protective fixing layer, which is in turn placed inside the third protective fixing layer. The interface element and USB cable connection are nested within the first layer, which is nested within the second, which is nested within the third. This nested arrangement provides progressive protection while maintaining a compact overall structure that does not excessively increase device complexity.
2Strength
If multiple protective layers are added to prevent breakage, then durability improves, but manufacturing complexity increases
Solution Approach 1:
The USB cable is welded to the interface element before the protective layers are assembled. The first protective fixing layer is pre-formed and positioned to secure the welded connection. The second and third protective fixing layers are subsequently assembled in a sequential manner. This preliminary welding action ensures the connection is established before protective structures are added, simplifying the overall manufacturing process while still achieving enhanced durability through multiple protective layers.
Solution Approach 2:
The patent utilizes materials with different physical properties for each protective layer. The first protective fixing layer uses a material suitable for securing the connection, the second layer uses a material providing structural support, and the third layer uses a material offering external protection. By changing material parameters (composition, hardness, flexibility) for each layer, the patent achieves comprehensive protection against breakage while maintaining ease of manufacture through selective material properties that facilitate assembly.

AI summary
An anti-loose data cable contains: an interface element, a first protective fixing layer, a second protective fixing layer, a third protective fixing layer, a positioning head, and a USB cable. The interface element is welded with the USB cable, on a connection area of the interface element and the USB cable is fixed the first protective fixing layer, and the interface element and the first protective fixing layer are accommodated in the second protective fixing layer, wherein a main part of the second protective fixing layer is accommodated in the third protective fixing layer, and the third protective fixing layer and the positioning head are integrally formed together.
