Fishing Rod Vibration Sensing for Pre-Bite State Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fishing rod technologies only detect fish bite and fail to accurately recognize the fishing state from when a fishing rig is thrown until the fish is hooked, missing crucial pre-bite and post-bite states.
Innovation Solution
A fishing state detection/transmission device with a vibration generation unit, first and second detection units, and an information processing unit that generates and transmits vibration signals based on time-series data to detect and notify the fishing state, including pre-bite and post-bite states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If only fish bite detection is implemented, then the detection device is simple, but the fishing state recognition is incomplete
Solution Approach 1:
The detection device is divided into multiple independent detection units: a first detection unit for detecting rod body vibration, a second detection unit for detecting grip portion vibration, and a vibration generation unit. Each unit focuses on specific aspects of fishing state detection, allowing comprehensive information collection while maintaining modular simplicity in each component.
Solution Approach 2:
The detection device is designed to perform multiple functions: detecting pre-bite states through rod body vibration, detecting actual fish bite through grip portion vibration, and providing tactile feedback through the vibration generation unit. This multi-functional approach enables complete fishing state recognition without requiring separate specialized devices for each function.
2Measurement precision
If multiple detection units are added to detect pre-bite and post-bite states, then the fishing state recognition is improved, but the device complexity increases
Solution Approach 1:
Different detection units are placed at specific locations with different detection characteristics: the first detection unit is positioned to detect rod body vibration for pre-bite states, while the second detection unit is positioned to detect grip portion vibration for actual fish bite. Each unit is optimized for its specific detection task, achieving high measurement precision without requiring all units to be complex.
Solution Approach 2:
The vibration generation unit receives detection results from both detection units and generates corresponding vibrations to provide tactile feedback to the angler. This feedback mechanism helps the angler distinguish between different fishing states (pre-bite vs. actual bite) based on the pattern and intensity of vibrations, effectively enhancing detection precision through human sensory interpretation rather than requiring purely electronic complexity.
