Solution Overview

Problem

Conventional fishfinder systems require operators to perform multiple complex operations to direct a ship to a location where a school of fish was previously detected, leading to inaccuracies in identifying the exact location of moving fish schools.

Innovation Solution

A fishfinder data display device that allows operators to simply specify a destination on a touch screen, associating fishfinder data with locations and instructing an autopilot device to navigate to that location, using a touch panel device with a memory to store and display fishfinder data and an oscillator to acquire underwater data.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If the operator uses conventional fishfinder operations to direct the ship to a previously detected fish school location, then the ship can reach the general area, but the operation requires multiple complex steps and the exact location cannot be accurately identified

Engineering Contradiction:
Improvelocation identification accuracyVSAvoidoperation complexity
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The system pre-stores the exact location data where fish schools were detected, associated with the fishfinder data. When the operator selects past fishfinder data for display, the location information is already prepared and stored, eliminating the need for manual estimation and trace analysis. This preliminary preparation of location data enables direct navigation to the exact spot where fish were detected.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The display device acts as an intermediary that directly connects the stored location data with the autopilot system. Instead of requiring the operator to manually estimate location from traces, the system provides the exact coordinates through the display interface, which then automatically transmits this precise location to the autopilot for navigation. This intermediary function eliminates the manual estimation step and its associated errors.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If the operator performs manual estimation of fish school location based on time and trace, then some navigation information can be obtained, but the exact moving location of the fish school cannot be identified

Engineering Contradiction:
Improvefish school location accuracyVSAvoidoperation time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The system pre-captures and stores the exact location data at the moment fish schools are detected, associating this spatial information with the fishfinder data in memory. This preliminary recording of precise location eliminates the need for later manual estimation based on traces, providing immediate access to accurate position information when reviewing past detection data.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system creates a digital copy of the exact location data where fish schools were detected, storing it as structured information rather than requiring reconstruction from visual traces. This copied location data can be directly retrieved and used for navigation, replacing the time-consuming manual estimation process with instant data access.

Inventive Principle:
Principle #26Copying

3Ease of operation

If the system stores and displays fishfinder data with location association, then direct navigation to detected locations becomes possible, but the device complexity increases

Engineering Contradiction:
Improvenavigation instruction simplicityVSAvoiddata storage and processing complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The display device is designed to perform multiple functions: displaying fishfinder data, storing location information, enabling selection of past data, and automatically transmitting navigation instructions to the autopilot. By making the display device universal and multi-functional, the system avoids adding separate dedicated devices for each function, thereby managing complexity while providing integrated navigation capabilities.

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

Solution Approach 2:

The system merges the location storage function with the fishfinder data storage, associating spatial coordinates directly with detection data in the same memory structure. It also combines the display, selection, and autopilot control functions into an integrated workflow where one operation triggers the next automatically. This merging reduces the number of separate components and interfaces the operator must interact with.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A fishfinder data display device is provided. The display device includes a memory for storing fishfinder data obtained by a fishfinder detecting underwater and a location where the fishfinder data is acquired so as to associate the fishfinder data with the location, a display unit for displaying an image created based on the fishfinder data, and a controller, when an operator performs a specifying operation to a predetermined part of the image displayed by the display unit, for reading the location corresponding to the fishfinder data based on the specified predetermined part of the image from the memory, and causing an autopilot device to execute an autopilot operation with the location as a destination.
