Braider for Flexible Waveguide Outer Conductor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional metal wire transmission methods struggle to support high-speed communication speeds of several tens of Gbps for short-distance data transmission, and optical communication technologies are costly and unreliable for repeated connections, limiting their adoption in popular price-range products.
Innovation Solution
A braider is used to form a flexible waveguide with a braided outer conductor from flat foil yarns, ensuring no inversion of the yarns by maintaining constant tension and multiple cross points, combined with a core material supply and waveguide take-out mechanism, to create a reliable and cost-effective high-speed communication solution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If optical communication technology is used for high-speed transmission, then communication speed is improved, but cost increases significantly
Solution Approach 1:
The patent replaces expensive optical communication components with a cost-effective flexible waveguide structure that uses millimeter wave transmission. The waveguide employs a simple construction with a flexible dielectric core and braided outer conductor, eliminating the need for costly optical transmitters and receivers while achieving comparable high-speed transmission performance
Solution Approach 2:
The patent transitions from optical frequency transmission to millimeter wave frequency transmission, changing the fundamental operating parameter. This parameter change enables high-speed communication using conventional electromagnetic transmission methods rather than requiring expensive optical infrastructure, making high-speed communication accessible in popular price-range products
2Speed
If optical communication transmission/reception unit is used, then communication speed is improved, but connection reliability deteriorates due to sensitivity to dust and connection accuracy requirements
Solution Approach 1:
The patent replaces the fragile optical connection system with a robust mechanical waveguide connection. The flexible waveguide structure with its braided outer conductor and flexible dielectric core creates a durable physical connection that is insensitive to dust and alignment errors, eliminating the reliability issues inherent in optical connectors while maintaining high-speed transmission capabilities
3Ease of manufacture
If flat foil yarns are braided without inversion control, then manufacturing process is simplified, but transmission characteristics become unstable
Solution Approach 1:
The patent incorporates a carrier movement determination mechanism that monitors and controls the braiding process. This feedback system ensures that flat foil yarns are fed in the correct orientation and that cross points are properly formed, maintaining stable transmission characteristics while automating the process to prevent manual errors. The mechanism provides real-time control without significantly complicating the manufacturing setup
Solution Approach 2:
The patent implements preliminary control measures during the braiding process, specifically ensuring that flat foil yarns are fed from bobbins in a controlled manner and that carrier movements are predetermined to create the correct braid pattern. This preliminary action prevents inversion issues before they occur, ensuring consistent transmission characteristics without requiring complex post-processing or inspection

AI summary
A braider includes: a plurality of cylindrical bobbins around which flat foil yarns are wound so as not to be inverted; a plurality of carriers to which the bobbins are rotatably attached, the plurality of carriers being configured to feed out the flat foil yarns from the bobbins; a core material supply mechanism configured to supply a core material to be placed inside the outer conductor; a waveguide take-out mechanism configured to take out the flexible waveguide after the outer conductor is formed; and a carrier movement determination mechanism configured to determine movement of the carriers so that there are always three or more cross points formed by the individual flat foil yarns with other ones of the flat foil yarns in an enlarged portion before the flat foil yarns form a braided shape.
