Ceramic Fishing Line Guide Structure for Less Twist and Tangle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fishing line guides made of metal components suffer from issues such as increased weight, size, line tangling, and twisting due to high friction coefficients, and require multiple parts that can lead to corrosion and joint weaknesses.
Innovation Solution
A fishing line guide formed integrally of ceramic material with a concave shape and arc-shaped contours to reduce weight, minimize friction, and enhance rigidity and strength, eliminating the need for separate guide rings and reducing stress concentrations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a metal-formed frame with separate ring portion and frame portion is used, then the guide structure is simple, but the weight and size increase
Solution Approach 1:
The patent merges the ring portion and frame portion into a single integrated guide body made of ceramic material. This eliminates the need for separate components and their connecting joints, thereby reducing overall weight and size while maintaining structural simplicity through the unified design.
2Strength
If a metal-formed frame is used, then the guide structure is strong, but the friction coefficient increases causing line tangling and twisting
Solution Approach 1:
The patent changes the material parameter from metal to ceramic, which fundamentally alters the friction characteristics. The ceramic material provides a lower friction coefficient compared to metal, reducing line tangling and twisting while maintaining sufficient strength through the ceramic material's inherent mechanical properties.
3Weight of moving object
If the guide frame thickness is reduced to reduce weight, then the weight decreases, but the strength and rigidity may be compromised
Solution Approach 1:
The patent employs ceramic material, which offers superior strength-to-weight ratio compared to traditional metal materials. This allows the guide frame to be made with reduced thickness while maintaining or even enhancing strength and rigidity, as ceramic materials provide high strength characteristics that compensate for the thinner profile.

Function Achieved in This Case
The ceramic fishing line guide effectively reduces weight and friction, minimizing line tangling and twisting while maintaining strength and durability, even under impact.
Implementation Method 1
the line may come into contact with the metal portion, which has a large friction coefficient, causing an issue of the occurrence of line tangling and line twisting
Implementation Method 2
an outer contour on an inner surface side of the fishing line guiding portion and the connection portion is curved in an arc shape
