Solution Overview
Problem
Existing automatic jerking devices for fishing are limited in their ability to detect bites accurately, require manual operation, and lack adjustability for different fishing conditions and user skill levels, leading to inefficiencies and fatigue.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If an automatic jerking device is used to detect bites and perform jerking automatically, then fishing efficiency is improved and user fatigue is reduced, but the device complexity increases
Solution Approach 1:
The automatic jerking device is divided into independent functional modules: a biting signal detection member for detecting fish bites, a trigger mechanism for initiating jerking, a latch for controlling the jerking action, and an elastic wire for providing restoring force. Each module performs a specific function, allowing the system to achieve automatic jerking while maintaining manageable complexity through modular design.
Solution Approach 2:
The device is designed to automatically detect bites through the biting signal detection member and automatically execute jerking actions through the trigger and latch mechanisms, eliminating the need for continuous manual monitoring and operation. The elastic wire automatically restores the mechanism to its initial state after each jerking action, enabling continuous automatic operation without user intervention.
2Measurement precision
If the biting signal detection member is made highly sensitive to detect all bites, then bite detection accuracy is improved, but false triggering increases due to minor line movements
Solution Approach 1:
The rotation switch is designed with an adjustable threshold parameter that determines the rotation angle required to trigger the jerking mechanism. By adjusting this threshold, the system can differentiate between significant bite signals and minor line movements, allowing optimization of detection sensitivity while minimizing false triggering based on the specific fishing conditions and target fish species.
3Strength
If the jerking force is increased to ensure fish are hooked, then hooking success is improved, but the fishing line may break or the bait may be lost
Solution Approach 1:
The elastic wire provides a periodic restoring force that automatically returns the trigger and latch mechanism to their initial positions after each jerking action. This periodic action allows the system to deliver strong jerking forces when needed while naturally resetting to a lower force state, reducing the risk of line breakage or bait loss during non-bite periods.
4Adaptability or versatility
If the device is designed to work with various fishing postures (hand-held or supported), then adaptability is improved, but the device structure becomes more complex
Solution Approach 1:
The base is designed with a universal mounting structure that can accommodate different fishing postures and configurations. The biting signal detection member, trigger, and latch mechanisms are arranged to function effectively whether the fishing rod is held by hand or supported on a rest, allowing a single device design to serve multiple fishing scenarios without requiring additional complex components.
