Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If multiple separate tracking systems are used for different types of objects, then each object type can be tracked with specialized precision, but the system complexity and resource consumption increase significantly

Engineering Contradiction:
Improvetracking precisionVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent combines multiple separate tracking systems into a single unified tracking system that can handle different object types (aerial, surface, subsurface) through a common infrastructure. The system uses a single set of tracking servers, database servers, and communication protocols to manage all object types, eliminating the need for duplicate specialized systems while maintaining tracking precision through object-type-specific processing algorithms.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The unified tracking system is designed with multi-functionality to handle diverse object types including aerial vehicles, surface vessels, and subsurface objects. The system uses universal tracking servers and database structures that can process and store information for different object categories, with the ability to adapt to various tracking requirements through configurable parameters and object-type-specific processing rather than requiring separate dedicated systems.

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

2Reliability

If separate tracking systems are deployed for different object types, then each system can be optimized for its specific purpose, but the overall resource consumption and operational burden increase

Engineering Contradiction:
Improvetracking reliabilityVSAvoidresource consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent merges multiple tracking systems into a single unified system that shares common infrastructure resources including tracking servers, database servers, and communication channels. This consolidation reduces redundant resource consumption while maintaining tracking reliability through centralized coordination and shared data structures that serve all object types efficiently.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The unified system employs multi-functional tracking servers and database structures that can serve multiple object types simultaneously. The system allocates resources dynamically based on object type and tracking requirements, allowing a single set of infrastructure components to perform multiple tracking functions rather than requiring dedicated resources for each object category.

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

3Device complexity

If a unified tracking system is used for all object types, then system complexity and resource consumption are reduced, but the precision and reliability for specific object types may deteriorate

Engineering Contradiction:
Improvesystem complexityVSAvoidtracking precision
Core Design Contradiction:
Device complexityVSMeasurement precision

Solution Approach 1:

The unified tracking system implements segmentation by dividing the tracking process into object-type-specific processing stages. The system separates the handling of aerial objects, surface objects, and subsurface objects into distinct processing streams with specialized algorithms for each category, allowing precision-optimized processing within each segment while maintaining overall system unity and reduced complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system applies local quality by implementing object-type-specific tracking algorithms and parameters at the processing level while maintaining a unified infrastructure. Each object category receives customized processing attention with appropriate precision settings, data structures, and tracking methods tailored to its specific requirements, ensuring high tracking precision for each local object type within the global unified system.

Inventive Principle:
Principle #3Local quality
