Fishing Reel Guide Body Dynamics for Unwinding Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing fishing reel designs experience increased unwinding resistance when the fishing line is unwound in a vertically undulating manner due to the narrow lower portion of the fishing line guide body, which reduces the flying distance of the terminal tackle and unwinding speed.
Innovation Solution
A fishing reel with a fishing line guide body that includes an elongated opening wider than its width, allowing the guide body to rotate forward during unwinding to reduce contact resistance and backward during winding to ensure parallel winding, featuring a narrower guide section that comes into contact with the line to guide it back to the spool.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the fishing line guide body has a narrow lower portion to guide the fishing line to the spool in parallel, then the winding precision is improved, but the unwinding resistance increases
Solution Approach 1:
The fishing line guide body is designed to rotate between a first position (for unwinding) and a second position (for winding). During unwinding, it rotates to an orientation where the elongated opening is substantially parallel to the fishing line, reducing resistance. During winding, it rotates to guide the line parallel to the spool. This dynamic repositioning resolves the contradiction between unwinding resistance and winding precision.
Solution Approach 2:
The fishing line guide body incorporates an elongated opening with height larger than width, creating a dimensional difference. The fishing line passes through this opening, and the guide body's rotation changes the spatial relationship between the opening and the line. This dimensional approach allows the line to pass through with minimal contact resistance during unwinding while maintaining guidance during winding.
2Manufacturing precision
If the guide width of the fishing line guide body is reduced to allow parallel winding, then the winding uniformity is improved, but the unwinding speed is reduced
Solution Approach 1:
The guide body dynamically changes its orientation based on the operation mode. During unwinding, it rotates to minimize contact with the fishing line, allowing high-speed unwinding. During winding, it rotates to the second position where the narrow guide section contacts the line to ensure uniform parallel winding. This dynamic adaptation resolves the speed-precision contradiction.
3Speed
If the fishing line guide body is rotated forward to reduce unwinding resistance, then the unwinding speed is improved, but the parallel winding capability is lost
Solution Approach 1:
The system uses dynamic repositioning of the fishing line guide body between two distinct orientations. The first orientation (rotated forward) minimizes resistance for high-speed unwinding. The second orientation provides the narrow guide width needed for parallel winding. The ability to switch between these states resolves the contradiction between speed and precision.

AI summary
Provided is a fishing reel provided with a fishing line guide body capable of effectively reducing unwinding resistance applied to a fishing line when the fishing line is unwound from a spool in a vertically undulating manner. The fishing reel includes a level wind device including a fishing line guide body (60) through which the fishing line (S) unreeled from the spool is threaded. The fishing line guide body (60) includes a fishing line threading section (60A) that forms an elongated opening (65) of which a height in a vertical direction is larger than a width in a left and right direction. The fishing line guide body (60) is rotated forward and the fishing line threading section (60A) stands up in the vertical direction during the unwinding of the fishing line. The fishing line guide body is rotated rearward and the fishing line threading section (60A) falls down during the winding of the fishing line, so that a fishing line guide section (70) comes into contact with the fishing line (S) threaded through the fishing line threading section (60A).
