Fishing Rod Automatic Hooking Device with Preloaded Spring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fishing devices require manual tugging on the fishing rod to hook a fish, which can fail due to skill issues or delayed response, and the force is attenuated over distance, leading to ineffective hooking.
Innovation Solution
An automatic strike device mounted on the fishing line with a spring mechanism that triggers instantly when a fish takes the bait, ensuring an energetic and instantaneous pull on the hook, with water-soluble locking to prevent premature release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual tugging is used to hook a fish, then the angler can control the strike, but the response time is delayed and skill-dependent
Solution Approach 1:
The spring mechanism is pre-loaded before casting, storing elastic energy in advance. When the fish takes the bait and triggers the release mechanism, the pre-loaded spring immediately delivers the striking force without requiring the angler to react, thus eliminating response time delay while maintaining reliable hooking.
2Length of moving object
If the device is placed at a distance of 4 to 10 meters from the hook, then casting range is improved, but the tugging force is considerably attenuated
Solution Approach 1:
The spring acts as an intermediary force transmission mechanism between the device and the hook. Instead of relying on direct line tension over long distances, the spring stores and releases elastic energy locally at the device position, delivering full striking force to the hook regardless of the 4-10 meter casting distance, thus preventing force attenuation.
3Speed
If the spring is loaded before casting, then the device is ready to strike instantly, but the side pin may be accidentally disengaged during casting
Solution Approach 1:
The locking mechanism uses water-soluble material that changes its physical properties based on the environmental parameter (presence of water). Before casting (in air), the water-soluble material maintains a locked state preventing accidental disengagement. After casting (in water), the material dissolves, allowing the spring to be freely triggered by the fish taking the bait, thus enabling instant strike while preventing premature release.
