Solution Overview

Problem

Anglers lack detailed topographical maps of water bodies to identify optimal fishing locations, as existing sonar systems do not provide real-time, user-selectable, and comprehensive underwater imaging and mapping capabilities.

Innovation Solution

A sonar mapping system with a transducer assembly mounted on watercraft, coupled with a processor and display, which creates and updates real-time topographical charts of lakebeds, riverbeds, or seabeds, including bathymetric tints and contour lines, and allows users to select colors for vegetation and hardness indicators, and generates 3-D renderings for storage and display.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If real-time sonar data processing is implemented to create detailed topographical charts, then measurement precision and information completeness are improved, but device complexity and processing time increase

Engineering Contradiction:
Improvetopographical mapping precisionVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system segments the complex sonar mapping task into distinct functional modules: data acquisition from transducers, real-time processing through the processor, storage in memory, and display on the screen. This modular segmentation allows each component to handle specific aspects of the mapping process independently, improving overall system precision without proportionally increasing complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system performs preliminary actions by pre-processing sonar data through filtering and normalization before detailed topographical analysis. The processor prepares the raw sonar data in advance, organizing it into structured formats that facilitate more accurate and efficient real-time chart generation, thereby improving measurement precision while managing processing complexity.

Inventive Principle:
Principle #10Preliminary action

2Loss of information

If comprehensive sonar data collection for complete water body mapping is performed, then information completeness is improved, but loss of time and processing duration increase

Engineering Contradiction:
Improvetopographical data completenessVSAvoidmapping time
Core Design Contradiction:
Loss of informationVSLoss of time

Solution Approach 1:

The system implements continuous useful action by maintaining constant sonar data acquisition and real-time processing operations. The processor continuously receives sonar echoes, processes the data streams, and updates the topographical chart without interruption, ensuring complete water body mapping information is captured while minimizing idle time and overall mapping duration.

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

The system performs preliminary data organization and filtering operations on incoming sonar data before full topographical reconstruction. By pre-processing the raw sonar echoes to extract essential features and discard redundant information, the system prepares complete mapping data more quickly, reducing the time required for comprehensive water body visualization.

Inventive Principle:
Principle #10Preliminary action

3Measurement precision

If multiple sonar transducers are deployed for 360-degree imaging, then measurement precision and coverage area are improved, but device complexity and cost increase

Engineering Contradiction:
Improveangular resolutionVSAvoidtransducer array complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system merges multiple sonar transducers into a unified array system that functions as a single integrated imaging unit. By combining the signals from multiple transducers and processing them collectively through one processor, the system achieves 360-degree coverage and improved angular resolution without proportionally increasing overall system complexity. The merged approach allows coordinated operation of all transducers for comprehensive water body mapping.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The sonar transducer array is designed with multi-functionality to perform multiple imaging tasks simultaneously. The same array of transducers can capture data for complete water body mapping, generate detailed topographical charts, and provide real-time navigation assistance. This universal design improves measurement precision across various applications while avoiding the need for separate specialized systems, thereby managing complexity.

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