Solution Overview

Problem

Conventional GPS navigation systems are cumbersome and time-consuming, especially when creating routes that follow complex bottom contours in water bodies, making it difficult to navigate vessels accurately and efficiently along desired depth or contour lines.

Innovation Solution

The development of a system that converts selected lake bottom contour lines from digital maps into machine-readable codes, allowing GPS devices to automatically direct vessels along these contours without the need for manual route creation, using a Chart Library API that embeds proprietary LakeMaster Digital Charts, enabling seamless integration with vessel control devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If conventional GPS manual route creation is used, then route navigation is achieved, but the process is cumbersome and time-consuming

Engineering Contradiction:
Improveroute creation speedVSAvoidroute creation complexity
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The system pre-processes bottom contour data and stores it in digital map formats before navigation is needed. When a user wants to navigate along a contour, the data is already prepared and can be quickly selected and converted to machine-readable code, eliminating the need for manual route creation during navigation.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent replaces manual mechanical route plotting with automated digital processing. The system automatically converts selected bottom contour lines from digital maps into machine-readable code that can be directly used by vessel control devices, substituting manual operations with automated computational processes.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Measurement precision

If detailed bottom contour information is provided, then navigation accuracy along contours is improved, but the time required to process and create routes increases

Engineering Contradiction:
Improvecontour navigation accuracyVSAvoidroute creation time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

Detailed bottom contour data is pre-processed, stored, and organized in digital formats before navigation is needed. This allows the system to quickly retrieve and convert specific contour information without having to process raw data during navigation, maintaining both accuracy and speed.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system extracts only the specific bottom contour information needed for the desired route from the comprehensive digital map data. This selective extraction allows detailed navigation accuracy while minimizing processing time by focusing only on relevant contour lines rather than processing all available data.

Inventive Principle:
Principle #2Taking out (Extraction)
