Hollow Fishing Line Guide Frame with Reinforced Core
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fishing line guides face limitations in weight reduction while maintaining sufficient strength due to their solid construction.
Innovation Solution
A guide frame with a hollow frame body and core member, featuring a frame member, support legs, and attachment feet, where the core members are inserted into the support legs to provide structural reinforcement and weight reduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the guide frame is formed by punching out a metal plate to ensure sufficient strength, then the strength of the guide frame is maintained, but the weight reduction is limited
Solution Approach 1:
The guide frame is divided into multiple components: a frame body, multiple frame members, and core members. The frame members are positioned at different locations (first, second, third, and fourth positions) around the guide ring, segmenting the structural support function across multiple elements rather than using a single solid plate, thereby reducing weight while maintaining strength.
Solution Approach 2:
The guide frame combines different materials: the frame body is made of a lightweight material (such as aluminum alloy or resin), while the core members are made of a harder material (such as stainless steel or titanium). This composite construction allows the lightweight frame body to provide overall structure while the harder core members reinforce specific high-stress areas, achieving both weight reduction and sufficient strength.
2Strength
If core members are inserted in the curved portions of the support legs, then the structural reinforcement is improved, but the device complexity increases
Solution Approach 1:
The core members are nested inside the hollow frame body, specifically inserted into the curved portions of the support legs. This nesting arrangement allows the core members to be housed within the existing frame structure without requiring separate mounting spaces or complex assembly mechanisms, thereby providing reinforcement while minimizing additional complexity.
Solution Approach 2:
The core members are strategically positioned only in the curved portions of the support legs where bending stresses are highest, rather than uniformly throughout the entire frame. This localized reinforcement approach provides structural strength exactly where needed while avoiding unnecessary material and complexity in low-stress areas.
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
The solution allows for a reduction in weight while ensuring the strength of the guide frame, with the core members stabilizing the support legs through frictional resistance, enhancing the overall structural integrity.
Implementation Method 1
the core members are held at prescribed positions of the frame body due to the contact between the core member and the inner periphery of the frame body

AI summary
A guide frame of a fishing line guide includes a hollow frame body, and a core member inserted into at least a part of the frame body. The frame body includes a frame member configured to abut a prescribed angle region on a circumference of a guide ring, an attachment foots configured to attach to a fishing rod and a support leg configured to connect ends of the frame member and then attachment foots.
