Fishing Reel Bite Alert Sensitivity Adjustment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fishing reels with electronic bite alerts lack adjustability to compensate for external forces such as water currents, bait weight, and wind, leading to inaccurate bite detection.
Innovation Solution
A sensitivity adjustment mechanism that allows users to calibrate the force required to activate the bite alert using a force sensor or adjustable spring force, enabling compensation for external line tensions through a calibration slider and sensitivity switch, providing infinitely gradable or stepped adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a fixed force threshold is used for bite alert activation, then the device structure is simple, but the accuracy of bite detection deteriorates due to inability to compensate for external forces
Solution Approach 1:
The patent implements a sensitivity adjustment mechanism that transforms the fixed force threshold into a dynamically adjustable parameter. Users can modify the spring force or cam position to adapt the bite alert threshold to different fishing conditions, thereby improving detection accuracy without requiring complex electronic systems
Solution Approach 2:
The patent changes the physical parameter of the activation force by introducing an adjustable spring mechanism or cam system. This allows the force threshold to be varied manually based on external conditions such as water current, bait weight, and wind, resolving the contradiction between simplicity and accuracy
2Adaptability or versatility
If sensitivity adjustment mechanism is added, then the adaptability to different fishing conditions is improved, but the device complexity increases
Solution Approach 1:
The sensitivity adjustment mechanism is designed as a separate, modular component that can be independently adjusted without affecting the core bite alert functionality. The adjustment mechanism is segmented into discrete elements (spring, cam, lever) that work together to provide adaptability while maintaining overall system simplicity
Solution Approach 2:
The adjustment mechanism is designed to be manually operable by the user without requiring technical expertise or complex procedures. The self-service nature of the adjustment allows users to adapt the device to different conditions themselves, reducing the need for complex control systems
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
Enables more accurate bite alerts by allowing users to customize sensitivity based on fishing conditions, effectively offsetting external forces and improving detection reliability.
Implementation Method 1
An adjustable spring force that acts on the anti-reverse system in an opposite direction than the direction that the line tension acts on the anti-reverse system
Implementation Method 2
The sensitivity switch has a cam member that selectively engages the sensitivity spring. By adjusting the orientation of the sensitivity switch, the cam member exerts a force on the calibration spring.

AI summary
A fishing reel, such as a spincast reel or a spinning reel, has a clutch assembly mounted on a shaft adjacent to the rotating component, the clutch assembly for frictional engagement with a rotating component. The clutch assembly has a first and a second protuberance. A bite alert contact is located for engagement with the first protuberance. A calibration member is adjacent the clutch assembly for engagement with the second protuberance. The calibration member provides a selectable amount of resistance to rotation of the clutch assembly, thereby regulating an amount of rotational force required to activate the bite alert contact. The fishing reel may further include a sensitivity switch for adjusting the selectable amount of resistance provided by the calibration member, which may adjust the resistance in discrete amounts.
