Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If current targeting systems (AFATDS) are used for tracking moving targets, then basic terrain and mobility analysis can be performed, but the systems cannot predict future locations of moving targets effectively

Engineering Contradiction:
Improvetarget location prediction accuracyVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system performs preliminary analysis by pre-processing terrain data, road network information, and vehicle mobility characteristics before engagement. The Extended Kalman Filter is pre-configured with mobility models, and the fuzzy logic system is pre-populated with terrain and tactical rules, enabling rapid prediction when targets move.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system transitions from static 2D terrain analysis to dynamic 4D (3D space + time) prediction by incorporating temporal dimensions. This adds time as a fourth dimension to track target movement trajectories and predict future positions, transforming static geographic information into dynamic predictive models.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If static terrain and mobility analysis is performed, then basic attack planning can be supported, but dynamic battlefield environments cannot be adequately addressed

Engineering Contradiction:
Improveadaptability to dynamic environmentsVSAvoidloss of real-time battlefield information
Core Design Contradiction:
Adaptability or versatilityVSLoss of information

Solution Approach 1:

The system implements continuous feedback loops where predicted target positions are compared with actual sensor detections. The Extended Kalman Filter uses measurement updates to correct prediction errors, and the fuzzy logic system adapts its rules based on new battlefield information, ensuring the system remains adapted to dynamic environments.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system transforms static terrain and mobility models into dynamic adaptive models. The mobility models are updated in real-time based on observed target behavior, and the fuzzy logic rules are dynamically adjusted according to changing battlefield conditions, enabling the system to adapt to evolving scenarios.

Inventive Principle:
Principle #15Dynamics

3Measurement precision

If multiple data sources (GIS, target statistics, tactics, terrain) are synthesized for trajectory prediction, then prediction accuracy is enhanced, but computational complexity increases

Engineering Contradiction:
Improvetrajectory prediction accuracyVSAvoidcomputational energy consumption
Core Design Contradiction:
Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The prediction system is segmented into distinct functional modules: the Extended Kalman Filter handles dynamic state estimation using mobility models, while the fuzzy logic system processes terrain and tactical constraints separately. This modular segmentation allows independent optimization and efficient resource allocation for each processing task.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system dynamically adjusts processing parameters based on operational context. The fuzzy logic system adjusts its rule activation and processing depth based on target type, terrain complexity, and engagement phase, reducing computational energy consumption when full prediction accuracy is not required while maintaining precision when needed.

Inventive Principle:
Principle #35Parameter changes

AI summary

The technology of the 4D-GIS system deploys a GIS-based algorithm used to determine the location of a moving target through registering the terrain image obtained from a Moving Target Indication (MTI) sensor or small Unmanned Aerial Vehicle (UAV) camera with the digital map from GIS. For motion prediction the target state is estimated using an Extended Kalman Filter (EKF). In order to enhance the prediction of the moving target's trajectory a fuzzy logic reasoning algorithm is used to estimate the destination of a moving target through synthesizing data from GIS, target statistics, tactics and other past experience derived information, such as, likely moving direction of targets in correlation with the nature of the terrain and surmised mission.
