Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High frequency cables with stranded center conductors experience electrical property degradation due to depression formation on the outer peripheral surface, which is exacerbated in high frequency signal transmission.
Innovation Solution
A high frequency cable design featuring a center conductor with a hexagonal core and fan-shaped surrounding wires, where the wires are stranded to form a continuous circular peripheral surface, preventing gap formation and enhancing electrical properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional stranded wires are used to form the center conductor, then flexibility and ease of manufacture are improved, but gap formation occurs on the outer peripheral surface leading to electrical property degradation
Solution Approach 1:
The patent applies local quality by giving each surrounding wire a specific fan-shaped cross-section with curved outer peripheral surface, designed to match and complement adjacent wires. This local geometric optimization ensures that when wires are stranded, their curved surfaces interlock to form a substantially continuous outer peripheral surface, eliminating gaps at contact points while maintaining the overall stranded structure's flexibility and manufacturability.
2Adaptability or versatility
If stranded center conductor is used, then flexibility is improved, but depression formation occurs on outer peripheral surface exacerbating electrical property degradation in high frequency transmission
Solution Approach 1:
The patent employs spheroidality by designing each surrounding wire with a fan-shaped cross-section where the outer peripheral surface is formed by a curved line (circular arc). This curvature allows the wires to nestle together like puzzle pieces when stranded, creating a substantially continuous outer peripheral surface without depressions or gaps, thereby maintaining electrical integrity while preserving the flexibility inherent in stranded construction.
3Reliability
If adjacent second wires are in contact with each other, then continuous peripheral surface is formed improving electrical properties, but manufacturing precision requirements increase
Solution Approach 1:
The patent applies parameter changes by modifying the cross-sectional geometry of surrounding wires from conventional circular or rectangular shapes to fan-shaped sections with specifically designed curved outer peripheral surfaces. This geometric parameter transformation ensures that when wires are stranded with standard tolerances, their curved surfaces naturally interlock to form a continuous outer peripheral surface, achieving high electrical performance without requiring excessive manufacturing precision.

AI summary
A high frequency cable includes a center conductor comprising one first wire, which is located at the center of the center conductor, and a plurality of second wires, which are located around that one first wire, and the one first wire and the plurality of second wires are stranded together. Respective outer peripheral surfaces of the plurality of second wires constitute a substantially continuous circular peripheral surface as an outer peripheral surface of the center conductor.
