Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If AI/ML models are used for wireless positioning, then positioning accuracy is improved compared to traditional methods, but model generalization performance deteriorates due to complexity and variability of wireless communication environments

Engineering Contradiction:
Improvepositioning accuracyVSAvoidmodel generalization performance
Core Design Contradiction:
Measurement precisionVSAdaptability or versatility

Solution Approach 1:

The patent implements dynamic model selection where the network entity chooses different AI/ML models based on real-time environmental conditions and positioning requirements. The system dynamically adjusts model parameters and selects appropriate models from a set, enabling adaptation to varying wireless environments without requiring complete retraining, thus improving both accuracy and generalization.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent modifies model training parameters and configuration settings based on specific positioning scenarios and available resources. By adjusting training parameters such as learning rate, batch size, and model complexity levels, the system optimizes model performance for different environments while maintaining the ability to generalize across various wireless communication scenarios.

Inventive Principle:
Principle #35Parameter changes

2Measurement precision

If customized training is performed for AI/ML models to improve positioning accuracy in specific environments, then positioning accuracy is improved, but training time and computational resources increase

Engineering Contradiction:
Improvepositioning accuracyVSAvoidtraining time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent pre-trains multiple AI/ML models on different environmental scenarios and stores them in a repository before actual positioning operations. When positioning is needed, the system selects from pre-trained models rather than performing training in real-time, significantly reducing training time while maintaining high accuracy for various environments.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent performs partial training or fine-tuning rather than complete retraining of models for each specific scenario. By using transfer learning and only training necessary portions of the model based on available data and requirements, the system achieves improved accuracy while minimizing computational resource consumption and training time.

Inventive Principle:
Principle #16Partial or excessive action

3Adaptability or versatility

If multiple AI/ML models are maintained for different positioning scenarios, then adaptability to various environments is improved, but device complexity and model management overhead increase

Engineering Contradiction:
Improveenvironmental adaptabilityVSAvoidmodel management complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent divides the model management system into modular components including a model repository, selection module, and training module. Each component handles specific functions independently, making the complex system of multiple models manageable through structured organization and separation of concerns.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements feedback mechanisms where the network entity monitors positioning performance and environmental conditions to automatically select appropriate models. The system uses performance feedback to adjust model selection and training priorities, reducing manual management complexity while maintaining high adaptability across different scenarios.

Inventive Principle:
Principle #23Feedback
