Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Monitoring fishing events, such as fish strikes and changes in tide conditions, is challenging for sports and commercial fishermen, especially during trolling, due to the complexity of interpreting vibrations in dynamic fishing environments.
Innovation Solution
The implementation of inertial measurement units (IMUs) coupled to fishing tackle to measure vibrations, which are then analyzed using data processing systems to determine fishing events and transmit signals to output devices, enabling real-time notification of critical fishing occurrences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If anglers manually monitor multiple trolling assemblies during critical events, then they can detect fishing events, but they may miss catches due to divided attention and complex interpretation requirements
Solution Approach 1:
The patent replaces the mechanical system of manual visual monitoring and tactile sensing with an electronic sensor-based system. Sensors attached to fishing rods and reels automatically detect vibrations, movements, and operational parameters, converting physical fishing events into electronic signals that are processed and presented to the angler, thereby eliminating the need for complex manual interpretation
Solution Approach 2:
The monitoring system performs self-service by automatically detecting, analyzing, and reporting fishing events without requiring continuous angler attention. The system monitors multiple assemblies simultaneously, processes sensor data autonomously, and provides alerts only when relevant events occur, freeing the angler from constant monitoring while maintaining high detection accuracy
2Productivity
If anglers focus on piloting the boat and monitoring multiple assemblies simultaneously, then they can manage the trolling operation, but they experience divided attention leading to missed catches
Solution Approach 1:
The patent replaces manual monitoring capacity with electronic sensing systems that can simultaneously track multiple assemblies without division of attention. Sensors on each rod and reel independently detect fishing events, and the system processes all signals concurrently, enabling reliable monitoring of multiple assemblies while the angler focuses on boat piloting
Solution Approach 2:
The system introduces an intermediary processing unit that acts as a mediator between multiple fishing assemblies and the angler. This intermediary automatically correlates sensor data from multiple sources, filters out irrelevant signals, and presents synthesized information to the angler, enabling reliable multi-assembly monitoring without requiring the angler's divided attention
3Measurement precision
If manual interpretation of rod motion and cable response is used, then fishing events can be detected, but accuracy is reduced due to environmental factors such as tide conditions, trolling speed, and line tension
Solution Approach 1:
The patent replaces subjective manual interpretation with objective sensor-based detection. Multiple sensors measure specific physical parameters (vibrations, tension, movement) that are less affected by environmental factors. The system processes these measurements to distinguish true fishing events from environmental noise, significantly improving detection accuracy while the added device complexity is offset by the automated nature of the system
Solution Approach 2:
The monitoring system is designed with multi-functionality to handle various fishing conditions universally. The same sensor suite and processing algorithms work across different tide conditions, trolling speeds, and assembly configurations, eliminating the need for angler adaptation to each condition while maintaining high detection accuracy through consistent automated measurement
