Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If piezoelectric sensors are used for bite detection, then the sensor is simple with no moving parts improving reliability, but the sensor parameters cannot be adjusted during use making it difficult to control sensitivity in varying conditions
Solution Approach 1:
The patent applies parameter changes by using an accelerometer that allows dynamic adjustment of sensitivity parameters during operation. The control unit can modify the accelerometer's detection threshold and sensitivity in real-time based on environmental conditions such as weather, water current, and vibration levels, enabling the system to adapt to varying fishing conditions while maintaining reliable bite detection.
2Measurement precision
If high sensor sensitivity is used to improve bite detection chance, then more bites are detected, but false bite indications increase in strong current, rain, or vibrations from walking past the rod
Solution Approach 1:
The patent implements feedback by using the control unit to continuously monitor environmental conditions and adjust the accelerometer's sensitivity threshold accordingly. The system receives feedback about environmental factors such as water current strength, weather conditions, and nearby vibrations, and automatically adjusts the detection parameters to distinguish between legitimate bites and false signals, reducing false bite indications while maintaining high detection accuracy.
Solution Approach 2:
The system dynamically changes the accelerometer's detection parameters based on environmental conditions. When strong currents, rain, or vibrations are detected, the control unit increases the sensitivity threshold to filter out false signals. When calm conditions prevail, the threshold is lowered to maximize bite detection sensitivity, thus optimizing the balance between detection accuracy and false alarm reduction.
3Productivity
If multiple fishing lines are set up at one time, then more fishing opportunities are available, but close monitoring of each line becomes difficult
Solution Approach 1:
The patent applies universality by designing a bite detector system that can simultaneously monitor multiple fishing lines through the accelerometer's ability to detect movements across different lines. The control unit processes signals from all connected lines and provides unified alerts to the angler, enabling effective monitoring of multiple lines without requiring close manual inspection of each one, thus improving fishing efficiency while maintaining ease of operation.
4Reliability
If pre-existing bite detection sensors are used, then basic bite detection is achieved, but additional data such as direction of movement cannot be derived
Solution Approach 1:
The patent applies parameter changes by utilizing the accelerometer's multi-axis measurement capability to extract additional data beyond basic bite detection. The control unit analyzes movement direction, intensity, and pattern parameters from the accelerometer signals, providing enriched information about the bite characteristics. This enables the system to detect not only that a bite occurred but also the direction and nature of the movement, deriving valuable additional data from the same sensor platform.
