Solution Overview
Problem
Most fishers struggle with precise throttle control of their fishing vessels, which is crucial for successful fishing, as they lack the natural ability to make the requisite throttle variations that properly animate the trolled bait.
Innovation Solution
A robotic-throttle control system that allows users to input or select throttle-power settings and power-duration settings, with real-time adjustments via a dual-stage switch and safety clutch mechanism, enabling precise control and adaptability to changing conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual throttle control is used by fishers, then the system is simple and easy to operate, but precise throttle control cannot be achieved and fishing success is reduced
Solution Approach 1:
A robotic throttle control system acts as an intermediary between the fisher and the vessel's throttle mechanism. The system includes a processor that receives input signals from various sensors (GPS, depth sensors, fish finder data) and automatically adjusts the throttle position to achieve precise speed control. This intermediary system handles the complex task of throttle management while keeping the user interface simple, allowing fishers to benefit from precision control without directly managing the complexity.
Solution Approach 2:
The robotic throttle control system continuously monitors vessel speed through GPS and other sensors, compares the actual speed with the target speed, and automatically adjusts the throttle position to maintain the desired speed. This closed-loop feedback mechanism ensures precise throttle control by constantly correcting deviations, enabling the system to achieve high measurement precision in speed maintenance without requiring manual intervention or complex user skills.
2Adaptability or versatility
If fixed throttle programs are used, then the control system is simple, but adaptability to changing fishing conditions is poor
Solution Approach 1:
The robotic throttle control system dynamically adjusts throttle settings based on real-time fishing conditions. It integrates data from multiple sources including GPS location, depth sensor readings, fish finder information, and weather data to continuously optimize speed. The system can modify throttle commands on-the-fly in response to changing conditions such as fish activity levels, water depth, current conditions, and bait depth requirements, providing high adaptability without requiring manual reprogramming.
Solution Approach 2:
The system performs self-adjustment of throttle settings based on pre-programmed fishing strategies and real-time sensor data. Fisher-specific parameters and fishing strategies are stored in memory, and the processor automatically selects and executes appropriate throttle patterns without requiring continuous user input. The system serves itself by autonomously interpreting sensor data and making throttle adjustments according to the stored fishing logic, enabling adaptability while maintaining simple operation for the fisher.
3Speed
If rapid throttle changes are allowed for quick response, then responsiveness is improved, but unsafe operating conditions may occur
Solution Approach 1:
The robotic throttle control system incorporates safety mechanisms that prevent rapid or unsafe throttle changes before they can occur. The processor includes programmed limits on the maximum rate of throttle change and monitors vessel operating conditions continuously. If a requested throttle change would exceed safe parameters, the system automatically cushions or limits the adjustment rate, ensuring that even in response to urgent fishing opportunities, throttle changes remain within safe operational boundaries. This prior cushioning approach maintains responsiveness while preventing unsafe conditions.

AI summary
A robotic throttle-control system for controlling a throttle-power setting of a throttle of a fishing vessel is provided. The control unit has a processor unit that instructs the control unit of the throttle-power setting at which to set the throttle and a time span for maintaining the throttle at the throttle-power setting. A user interface of the control unit has a dual-mode switch that communicates to the processor unit through both a rotational position of the dual-mode switch and an axial position of the dual-mode switch.
