Fishing Reel Spool Mode Switching for High-Speed Rotation Sensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fishing reels face excessive processing load when simultaneously performing detection and communication processing, especially during high-speed spool rotation, which hampers reliable operation.
Innovation Solution
The fishing reel employs a mode management system that selects between casting and drop modes based on spool rotation thresholds, disabling communication in the casting mode and enabling it in the drop mode, with shorter sampling times in the casting mode to manage processing load effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If communication processing is performed simultaneously with detection processing during high-speed spool rotation, then data can be transmitted to external devices, but the overall processing load becomes excessive
Solution Approach 1:
The system dynamically switches between casting mode and drop mode based on spool rotation speed. During high-speed rotation (casting mode), communication is suspended to reduce processing load. During low-speed rotation (drop mode), communication is enabled. This dynamic adaptation resolves the contradiction by adjusting system behavior according to operational conditions.
Solution Approach 2:
The system employs periodic sampling at different intervals based on operational mode. In casting mode, sampling occurs at shorter intervals to capture high-speed rotation data. In drop mode, sampling intervals are extended to allow communication processing. This periodic adaptation enables the system to manage processing load while maintaining data accuracy.
2Measurement precision
If frequent processing is performed to detect and record high-speed spool rotation during casting, then accurate detection is achieved, but communication with external devices is hindered
Solution Approach 1:
The system dynamically adjusts its operational state based on spool rotation speed. When rotation speed exceeds a threshold (casting mode), the system prioritizes detection processing with shorter sampling intervals and suspends communication. When rotation speed is below the threshold (drop mode), the system enables communication with longer sampling intervals. This dynamic switching resolves the contradiction between measurement precision and data transmission.
Solution Approach 2:
The system changes the sampling interval parameter based on operational mode. In casting mode, the sampling interval is set to a shorter value to accurately capture high-speed rotation data. In drop mode, the sampling interval is extended to allow communication processing. This parameter adaptation enables the system to maintain detection accuracy while managing communication requirements.
3Loss of information
If communication is enabled during high-speed casting, then data can be transmitted, but processing load increases and detection reliability decreases
Solution Approach 1:
The system dynamically determines operational mode based on spool rotation speed. During high-speed casting operations, the system automatically disables communication to minimize processing load and maintain detection precision. During low-speed drop operations, the system enables communication. This dynamic decision-making process resolves the contradiction by prioritizing detection precision when processing load would be excessive.
Solution Approach 2:
The system continuously monitors spool rotation speed and uses this feedback to adjust communication status. When rotation speed indicates casting conditions, the system suspends communication. When rotation speed indicates drop conditions, the system enables communication. This feedback mechanism ensures detection precision is maintained while enabling data communication under appropriate conditions.

AI summary
A fishing reel includes a spool capable of winding a fishing line, a detector capable of detecting the rotation amount of the spool, a storage that records the rotation amount of the spool as a detection result, and a transmitter that transmits the detection result to the outside, and is configured to select the casting mode when the detection result of the rotation amount of the spool is equal to or greater than a first threshold, and to select the drop mode when the detection result of the rotation amount of the spool is less than the first threshold.
