Fishing Rod Guide Frame Segmentation for Adhesion and Weight
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fishing rod guides face challenges in achieving a strong attachment force while minimizing weight and preventing tangling, due to limitations in contact area and shape matching between the guide ring and frame, leading to increased processing costs and potential breakage.
Innovation Solution
A guide for a fishing rod that incorporates a bonding assisting aid with first and second bonding portions bonded to the outer circumferential groove and inner surface of the frame, respectively, allowing for a larger contact area and enhanced adhesive force, even with differing shapes, and reducing the overall weight by minimizing the frame's size and avoiding unnecessary protrusions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the contact area between the frame and guide ring is increased by changing the cross-sectional shape of the frame, then the attachment force is improved, but the processing cost and labor increase
Solution Approach 1:
The frame is divided into multiple arc-shaped sections that can be separately formed and then assembled. This segmentation allows each section to be manufactured using simple circular wire rod processing, avoiding the need for complex cross-sectional shaping while still achieving a large total contact area when the sections are combined to form the complete frame.
2Area of stationary object
If the frame size is increased to match the shape of the peripheral groove, then the contact area is improved, but the overall weight of the guide frame increases
Solution Approach 1:
The frame is constructed from multiple discrete arc-shaped sections rather than a single large continuous structure. This segmentation allows the frame to achieve sufficient contact area through the cumulative effect of multiple smaller sections, while using only the minimum necessary material for each section, thereby reducing overall weight.
Solution Approach 2:
The frame sections are designed with varying arc angles and positions to optimize contact area distribution. Not all sections need to be uniformly large - the local geometry of each section is tailored to its specific position and function, achieving adequate total contact area without unnecessary material in any single location.
3Area of stationary object
If the frame protrudes beyond the outer circumferential groove, then the contact area is improved, but the fishing line may tangle and the frame may break
Solution Approach 1:
The frame is designed with flexible arc-shaped sections that can dynamically adapt to the groove geometry. The sections are sized and positioned to make full contact with the groove boundaries without creating rigid overhanging portions. This dynamic configuration ensures the frame remains within the groove confines while maintaining adequate contact area.

Function Achieved in This Case
The solution effectively increases the fixing force and reduces weight by optimizing the contact area and shape compatibility between the guide ring and frame, preventing tangling and breakage, while maintaining a cost-effective and efficient design.
Implementation Method 1
a bonding assisting aid that has a first bonding portion that is bonded to the outer circumferential groove, and a second bonding portion that is bonded to the inner circumferential surface of the frame
