Engineering Contradictions & Design Principles

VSEngineering 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

Engineering Contradiction:
Improvesensor reliabilityVSAvoidsensitivity adjustability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

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.

Inventive Principle:
Principle #35Parameter changes

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

Engineering Contradiction:
Improvebite detection accuracyVSAvoidfalse bite indications
Core Design Contradiction:
Measurement precisionVSObject-affected harmful factors

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.

Inventive Principle:
Principle #23Feedback

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.

Inventive Principle:
Principle #35Parameter changes

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

Engineering Contradiction:
Improvefishing efficiencyVSAvoidline monitoring difficulty
Core Design Contradiction:
ProductivityVSEase of operation

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.

Inventive Principle:
Principle #6Universality (Multi-functionality)

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

Engineering Contradiction:
Improvebite detection capabilityVSAvoidmovement direction data
Core Design Contradiction:
ReliabilityVSLoss of information

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.

Inventive Principle:
Principle #35Parameter changes
