Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If manual mapping of telemetry data to information model is performed, then mapping accuracy can be maintained, but time consumption and labor intensity increase significantly

Engineering Contradiction:
Improvemapping accuracyVSAvoidtime consumption
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent replaces the manual mechanical mapping process with an automated machine learning system. The ML model learns from example mappings between telemetry data and information models, then automatically performs the mapping without human intervention, thus reducing time consumption while maintaining accuracy through learned patterns.

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

Solution Approach 2:

The patent introduces an intermediate machine learning model that acts as a mediator between raw telemetry data and the target information model. This intermediary learns the mapping relationships from training data and applies them automatically, resolving the contradiction between speed and accuracy.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If manual expertise knowledge is transferred between experts, then mapping quality can be maintained, but knowledge transfer time increases

Engineering Contradiction:
Improvemapping qualityVSAvoidknowledge transfer time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent copies expert knowledge implicitly by training the ML model on examples of correct mappings created by experts. Instead of transferring knowledge through time-consuming instruction and communication, the system captures expert patterns in the training data and reproduces them automatically during inference.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The system enables self-service by allowing the ML model to learn and apply mapping knowledge independently without requiring ongoing expert intervention. Once trained, the model autonomously performs mapping tasks that previously required expert knowledge transfer.

Inventive Principle:
Principle #25Self-service

3Adaptability or versatility

If consistent information model structure is enforced across different buildings, then data compatibility improves, but adaptation effort increases

Engineering Contradiction:
Improvedata compatibilityVSAvoidadaptation effort
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent creates a universal ML model that can handle multiple building types and telemetry data formats. The model is trained on diverse examples from different buildings, enabling it to adapt to various data structures while outputting a consistent information model format, thus achieving compatibility without requiring building-specific adaptation logic.

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

Solution Approach 2:

The system handles building-specific variations by learning parameter transformations during training. The ML model adapts to different building configurations by adjusting its internal parameters based on the input data characteristics, while maintaining a standardized output structure for compatibility.

Inventive Principle:
Principle #35Parameter changes
