Adjustable Drag Lever Range to Prevent Fishing Line Entanglement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drag levers for dual-bearing fishing reels are prone to fishing line entanglement due to protrusions on the reel body, and they may not function optimally when used across different reel designs, leading to undesired operation ranges.
Innovation Solution
A drag lever with an adjustable operation range, featuring a mounting portion, operation portion, and an adjustment portion that allows for setting a predetermined operation range, eliminating the need for protrusions on the reel body and enabling compatibility across various reel designs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a protrusion is provided on the side surface of the reel body to define the operation range of the drag lever, then the operation range can be clearly defined, but the fishing line may become entangled on the protrusion during fishing
Solution Approach 1:
The patent removes the protrusion from the reel body side surface that was previously used to define the drag lever's operation range. Instead, the operation range is defined by the relative positions of the mounting portion on the reel body and the operation portion extending radially therefrom, eliminating the harmful protrusion that caused fishing line entanglement while maintaining clear operation range definition
2Adaptability or versatility
If the drag lever is configured for common use across different reel designs, then versatility is improved, but the drag lever may come into contact with the reel body or other components, preventing the desired operation range from being achieved
Solution Approach 1:
The patent enables the drag lever to adapt to different reel designs by making the operation range adjustable through the attachment of adjustment portions to either the mounting portion or operation portion. This dynamic configuration allows the drag lever to achieve the desired operation range across various reel types without coming into contact with other components, while maintaining versatility for common use

AI summary
A drag lever is configured to adjust a braking force of a drag mechanism configured to brake rotation of a spool, the drag lever including a mounting portion rotatably mounted on a reel body, an operation portion extending from the mounting portion in a radial direction of a pivot shaft and configured to swing in a first operation range, and an operation range adjustment member provided to the operation portion and configured to adjust the first operation range of the operation portion to a second operation range. This arrangement may suppress entanglement of a fishing line during fishing and adjusts the operation range of the drag lever.
