Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional development methods are used to develop aircraft control systems, then reliability can be achieved through thorough testing and validation, but the development time and complexity increase significantly

Engineering Contradiction:
ImprovereliabilityVSAvoiddevelopment time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by generating validation data and defining loss functions before the classifier is deployed. The system pre-generates candidate paths and validates them against graph models, creating a foundation that guides subsequent classifier training and refinement without requiring extensive post-deployment testing

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent implements feedback through the custom loss function that compares classifier outputs against pre-generated validation data. The loss score provides continuous feedback during training, allowing the system to iteratively improve classifier reliability by adjusting weights based on performance differences between predicted and valid paths

Inventive Principle:
Principle #23Feedback

2Productivity

If AI techniques are used to decrease development time, then productivity increases, but reliability and trustworthiness of the system decrease

Engineering Contradiction:
Improvedevelopment speedVSAvoidtrust dependability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent introduces an intermediary validation layer between the AI classifier and the final control decisions. The graph model and pre-generated validation data act as intermediaries that constrain and guide the AI's output, ensuring that even快速-generated classifications meet reliability requirements before being applied to aircraft control

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent uses parameter changes by adjusting the loss function weights and thresholds to balance speed and reliability. By modifying the parameters of the loss calculation (such as weighting different types of errors differently), the system can tune the classifier to achieve acceptable reliability levels while maintaining the efficiency benefits of AI-driven development

Inventive Principle:
Principle #35Parameter changes

3Reliability

If the classifier is heavily trained to reduce incorrect outputs, then reliability increases, but the training time and computational resources increase

Engineering Contradiction:
Improveclassifier reliabilityVSAvoidtraining time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by pre-generating comprehensive validation data and candidate paths before classifier training begins. This pre-computation creates a ready-made benchmark that accelerates the training process, as the classifier can immediately learn from clearly defined correct answers rather than requiring extensive iterative exploration

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent implements partial action by focusing training efforts on the most critical error types identified through the loss function. Rather than uniformly training on all possible scenarios, the system concentrates computational resources on correcting the most impactful classification errors, achieving sufficient reliability with less total training time

Inventive Principle:
Principle #16Partial or excessive action

4Reliability

If the classifier is trained on all possible scenarios to ensure consistency, then reliability improves, but the complexity and computational load increase

Engineering Contradiction:
Improveconsistent performanceVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies segmentation by dividing the scenario space into manageable segments represented as discrete graph nodes and edges. The graph model breaks down complex aircraft control scenarios into structured, hierarchical components that can be validated and trained upon independently, then combined to ensure overall consistency without requiring exhaustive training on every possible scenario combination

Inventive Principle:
Principle #1Segmentation
