Fishing Line Guide Fixing Structure With Inclined Pipes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for fixing fishing line guides on fishing rods are either heavy due to thick threads, prone to cracking, require skill, and result in unstable and costly installations, or have insufficient adhesion leading to the guide coming off, especially in harsh environments.
Innovation Solution
A fixing structure using inclined circular portions and fixing pipes that contact the fishing rod, eliminating the need for threads and providing secure axial and rotational fixation without increasing weight, with a larger adhesion area and enhanced durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If thread and thread setting agent are used to fix the fishing line guide, then the guide can be secured on the fishing rod, but the weight of the fishing rod increases and the thread setting agent may crack under bending stress
Solution Approach 1:
The invention extracts and eliminates the thread and thread setting agent from the fixing system. Instead of using these traditional binding elements, the patent employs a direct press-fit connection where the fishing line guide is inserted through the tip rod and secured by the structural design of the guide itself, removing the heavy and crack-prone thread-based fixing mechanism entirely.
Solution Approach 2:
The invention replaces the mechanical thread-wrapping system with a different mechanical approach: a press-fit insertion system. The fishing line guide is designed with an insertion hole that fits over the tip rod, and the guide body itself provides the fixing mechanism through its structural design, eliminating the need for separate thread and adhesive components.
2Reliability
If thread and thread setting agent are used to fix the fishing line guide, then the guide can be secured on the fishing rod, but the fixing requires skill and results in unstable qualities
Solution Approach 1:
The fishing line guide is designed to be self-fixing. The guide body includes an insertion hole that fits over the tip rod, and the guide's own structure provides the fixing mechanism. This eliminates the need for external thread-wrapping operations and adhesive application, allowing the guide to secure itself automatically during installation.
Solution Approach 2:
The fixing function is segmented into distinct components: the insertion hole in the guide body, the tip rod, and the guide body itself. This segmentation allows each component to perform its specific function independently, with the insertion hole providing positioning and the guide body providing structural support, simplifying the overall fixing process.
3Ease of manufacture
If a small adhesion area is used to fix the fishing line guide, then the guide can be attached to the fishing rod, but the adhesion strength becomes insufficient and the guide comes off
Solution Approach 1:
The invention transitions from a two-dimensional adhesion problem to a three-dimensional mechanical interlock. Instead of relying on surface area contact, the insertion hole creates a dimensional fit around the tip rod, and the guide body extends along the rod axis to provide distributed mechanical support, significantly increasing the effective fixing area and strength.
Solution Approach 2:
The fixing system combines multiple material properties: the insertion hole provides geometric constraint, the guide body material provides structural strength, and the combination creates a composite fixing mechanism that leverages both shape and material properties to achieve superior adhesion strength.

Function Achieved in This Case
The solution allows for lightweight, low-cost, and secure fixation of fishing line guides on fishing rods, preventing rotation and axial movement, while reducing the risk of cracking and maintaining strength even under bending stress.
Implementation Method 1
the end surfaces of the fixing pipes contact the surfaces of the circular portion, thereby to fix the fishing line guide on the fishing rod
Implementation Method 2
the fishing line guide is squeezed between the two fixing pipes and fixed on the fishing rod
