Shielded Point Motion Tackle: Dynamic Hook Deployment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional artificial fishing lures with sharp hooks pose safety hazards due to snagging and puncture risks, and existing solutions using spring mechanisms are impractical, unsafe, and often ineffective in retaining fish.
Innovation Solution
A sliding twin hook assembly with counter-rotating hooks that are shielded within a lure capsule chamber, activated by the differential pulling force between a fish and the fisherman, eliminating the need for springs or triggers and allowing hooks to extend only when a fish strikes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If sharp hooks are used on artificial lures to ensure fish capture, then fishing effectiveness is improved, but safety hazards from snagging and puncture wounds increase
Solution Approach 1:
The hook assembly is designed to be dynamic rather than static. The hooks are contained within a capsule chamber and can move from a retracted shielded position to an extended exposed position. This dynamic configuration allows the hooks to be hidden during handling and casting to prevent snagging and puncture wounds, then exposed when a fish strikes to ensure effective capture
Solution Approach 2:
The hook assembly is nested within a capsule chamber that is integrated into the lure body. The capsule chamber acts as a protective container that holds the hooks in a retracted position during normal handling. When activated by fish strike force, the capsule chamber opens to release the hooks for fishing
2Extent of automation
If spring mechanisms are used to activate hooks, then hook deployment is automated, but device complexity and safety risks increase
Solution Approach 1:
The hook assembly activates itself through the force of a fish strike rather than requiring external spring mechanisms or triggers. The differential pulling force between the fish and fisherman automatically opens the capsule chamber and deploys the hooks, eliminating the need for complex automated mechanisms while maintaining safety
Solution Approach 2:
The invention extracts and eliminates the spring mechanism and trigger device from the system. Instead of using complex automated mechanisms, the patent relies on the natural differential pulling force between fish and fisherman to activate the hook deployment, simplifying the overall device structure
3Object-affected harmful factors
If small treble hooks are used to reduce snagging, then safety is improved, but fish retention capability deteriorates
Solution Approach 1:
The hooks transition from a static small size to a dynamic configuration where larger hooks can be deployed when needed. The capsule chamber can hold multiple hooks of appropriate size for the target fish species, and these hooks are deployed only when a fish strikes, providing both safety during handling and effective retention during fishing
