Solution Overview

Problem

Conventional fishing systems lack centralized control to prevent tangles of fishing lines or hooks when a fish is hooked on one machine, leading to potential loss of caught fish and damage to other machines.

Innovation Solution

An automatic fishing system with multiple machines equipped with rotation drums, drive motors, electromagnetic clutches, and detection mechanisms to quickly wind up hooks of unhooked machines when a fish is detected, using sensors to determine hooking and control operations to prevent tangles.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If multiple fishing machines operate simultaneously without centralized control, then productivity increases, but tangle of fishing lines or hooks occurs when a fish is hooked

Engineering Contradiction:

Improvenumber of fishing machines operatingVSAvoidtangle prevention

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The system uses hooking detection means to continuously monitor each fishing machine for fish hooking events. When a fish is detected on one machine, this information is fed back to the fishing machine control means, which automatically controls other machines to wind up their fishing lines, preventing tangles while maintaining high productivity

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent combines multiple fishing machines into a single integrated system with centralized control. The fishing machine control means coordinates all machines as a unified system, merging their operations under common control to prevent conflicts between individual machine operations

Inventive Principle:

Principle #5Merging (Combining)

2Reliability

If crew manually control other fishing machines when a fish is hooked, then tangle prevention is achieved, but crew safety is compromised and other work is disturbed

Engineering Contradiction:

Improvetangle preventionVSAvoidcrew safety and workflow

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system enables self-service operation where the fishing machines automatically control each other without human intervention. When a fish is hooked on one machine, the control system automatically winds up other machines, eliminating the need for crew to manually intervene and ensuring crew safety while maintaining operational reliability

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces the mechanical system of manual crew operation with an automated electromagnetic control system. The fishing machine control means uses electromagnetic signals to automatically control the rotation drums and fishing lines, substituting human physical intervention with automated mechanical control

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Productivity

If many fishing machines operate without intervention, then productivity increases, but difficulty in rolling up all machines quickly increases

Engineering Contradiction:

Improvenumber of fishing machinesVSAvoidtime to roll up machines

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The hooking detection means continuously monitors all fishing machines and provides immediate feedback to the control system. This enables the system to quickly identify when a fish is hooked and automatically respond by winding up other machines, significantly reducing the time needed to manage multiple machines compared to manual intervention

Inventive Principle:

Principle #23Feedback

AI summary

An automatic fishing system includes a plurality of fishing machines each of which has rotation drums capable of winding fishing lines and capable of rotating in a reeling direction and an unreeling direction, a drive motor for driving the rotation drums in the reeling direction and the unreeling direction, and an electromagnetic clutch for transmitting rotation of the drive motor to the rotation drums, a hooking detection means for always detecting hooking of fish at any one of the plurality of fishing machines, and a fishing machine control means for controlling operations of the plurality of fishing machines in accordance with detection result of the hooking detection means. The fishing machine control means controls the rotation drums of other fishing machines that hook no fish in the reeling direction so that hooks of the other fishing machines are wound up to a water surface or near the water surface.
