Lightweight Fishing Line Guide Frame via Direct Rod Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fishing line guides at the tip end of fishing rods are heavy due to the rod insertion pipe, which reduces the sensitivity of fish bites detection at the butt end of the fishing rod.
Innovation Solution
A lightweight fishing line guide is designed with a frame directly fixed to the tip end of the tip rod via a retaining hole, eliminating the rod insertion pipe and using fiber-reinforced resin for the frame, which is continuous from the ring retainer to the support legs for enhanced strength and bending properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rod insertion pipe is used to attach the frame to the tip rod, then the frame can be securely retained, but the weight of the fishing line guide increases significantly
Solution Approach 1:
The invention extracts and removes the rod insertion pipe from the frame structure. The frame is designed to be directly attached to the tip rod without the intermediate pipe component, eliminating unnecessary weight while maintaining secure retention through direct bonding or mechanical attachment of the frame to the rod surface
Solution Approach 2:
The attachment function is segmented from the frame body. Instead of an integrated rod insertion pipe, the frame uses separate attachment mechanisms (bonding agents or direct mounting features) that allow secure retention without the heavy pipe structure extending from the frame
2Reliability
If a rod insertion pipe is used to attach the frame to the tip rod, then the frame can be retained, but the sensitivity of fish bite detection at the butt end of the fishing rod decreases
Solution Approach 1:
By removing the rod insertion pipe intermediate component, the frame achieves direct contact and connection with the tip rod. This direct connection creates a more efficient mechanical pathway for transmitting vibration and tactile signals from the line guide to the rod, improving the angler's ability to sense fish bites at the butt end
Solution Approach 2:
The frame and tip rod are merged into a more integrated connection by eliminating the pipe intermediary. This direct merging allows better mechanical coupling and signal transmission, enabling more sensitive detection of fish bite forces and vibrations along the rod structure
3Weight of moving object
If the frame is made of fiber-reinforced resin, then the weight is reduced and bending properties are improved, but the manufacturing complexity increases
Solution Approach 1:
The frame is constructed from fiber-reinforced resin composite material, which provides high strength-to-weight ratio and improved bending properties. The composite structure allows the frame to be lightweight yet sufficiently strong to withstand fishing loads while maintaining structural integrity
Solution Approach 2:
The material parameters of the frame are optimized by using fiber-reinforced resin with specific fiber orientation and resin matrix properties. This material selection achieves the desired balance between weight reduction, bending performance, and manufacturability through controlled material composition and processing parameters

AI summary
One object is to provide a lightweight fishing line guide that allows sharp sensing of fish bites. In accordance with one aspect, the line guide (1) of the present invention includes a frame (3) constituted by fiber-reinforced resin layers (5, 6) prepared by impregnating reinforcement fibers with a synthetic resin. The frame includes a ring retainer (H) retaining a guide ring (9) for admitting a fish line; a rod retainer (80) having a retaining hole (82) penetrating the frame and configured to be retained and fixed at a tip end of a tip rod of a fishing rod; and a support leg (6b) extending from the ring retainer (H) and tipped with a fixation portion (6a) to be fixed on a rod.
