Fishing Line Guide With Resin Attachment For Versatile Rod Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fishing line guides for telescopic fishing rods require extensive development time and costly metal dies due to the need for multiple frame sizes to fit different rod body diameters, and they can cause line tangling and damage if the fishing line becomes entangled with the frame.
Innovation Solution
A fishing line guide with a frame and attachment portion designed to fit various rod body diameters using a single frame size, featuring a resin attachment portion with a fitting hole and ridges to prevent line tangling and enhance coupling strength through an adhesive space, allowing the frame to be coupled to multiple attachment portions with different inner diameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a multiple number of metal-made frames with different sized attachment rings are manufactured to fit various rod body diameters, then the fishing line guide can be adapted to different rod bodies, but the number and cost of metal dies for working the frames become excessive
Solution Approach 1:
The patent applies universality by designing a single standardized frame structure that can be used across multiple fishing line guides intended for different rod body diameters. The frame is decoupled from the attachment portion, allowing one frame design to serve multiple functions with different attachment portions. This eliminates the need to manufacture separate metal dies for each frame size variation.
Solution Approach 2:
The patent segments the fishing line guide into distinct components: the frame (supporting the guide ring) and the attachment portion (resin-made annular structure). This segmentation allows the frame to be standardized while the attachment portion varies to match different rod body diameters. The attachment foot on the frame connects to the attachment portion through a fitting hole, enabling modular assembly without requiring custom frames for each application.
2Reliability
If the frame is designed to fit the dedicated attachment portion through the attachment ring, then the fishing line guide functions properly, but development time such as design time and metal die manufacturing time becomes excessive
Solution Approach 1:
The standardized frame design serves as a universal component that maintains proper fishing line guide functionality across different rod body applications. The frame's attachment foot connects to various attachment portions through a common fitting mechanism, eliminating the need for separate design and metal die manufacturing processes for each frame variant, thus significantly reducing development time.
Solution Approach 2:
The patent uses the same frame design (a copy of the proven structure) for multiple fishing line guide applications with different rod body diameters. Instead of creating new frame designs and metal dies for each application, the standardized frame is replicated and adapted through the modular attachment portion, reducing development time while maintaining functionality.
3Reliability
If the fishing line guide is installed at the tip side of the fishing rod, then it guides the fishing line effectively, but weight reduction becomes critical
Solution Approach 1:
The patent employs composite materials by using a resin-made attachment portion instead of traditional metal construction for the entire guide assembly. The resin attachment portion is coupled to the metal frame through an attachment foot, creating a hybrid structure that reduces weight while maintaining structural integrity and guidance effectiveness at the critical tip location of the fishing rod.
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
This design reduces development time and metal die costs, prevents line tangling, and achieves strong coupling force, making it suitable for use at the tip of a fishing rod where weight reduction and ease of use are critical.
Implementation Method 1
a portion of an adhesive agent is disposed between the frame and the attachment portion

AI summary
A fishing line guide attached to a rod body of a fishing rod is provided. The fishing line guide includes a guide ring through which a fishing line passes, a frame supporting the guide ring, and an attachment portion coupled to the frame and attached to the rod body. The frame has, at a lower end thereof, an attachment foot extending along a longitudinal direction of the rod body. The attachment portion is coupled to the attachment foot and is composed of a resin material. The attachment portion has a through bore to which the rod body is fitted, and a fitting hole to which the attachment foot is fitted. The fitting hole is spaced apart along the longitudinal direction from one end surface of the attachment portion and is formed at an outside of the through bore separately from the through bore in a radial direction.
