Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If rule-based classification and superficial pattern matching are used to analyze teaching materials, then the system is simple to implement, but the analysis precision and granularity are insufficient

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

Solution Approach 1:

The patent replaces rule-based classification and superficial pattern matching (mechanical systems) with a neural network-based semantic analysis system. The neural network automatically learns semantic relationships and conceptual structures from teaching materials, achieving high-precision concept identification without manual rule engineering. This substitution enables the system to understand the semantic meaning of questions and solutions at a deeper level, resolving the contradiction between analysis precision and system complexity.

Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If neural network-based semantic analysis is used to identify conceptual gaps, then the analysis granularity and adaptability improve, but the computational complexity and processing time increase

Engineering Contradiction:
ImproveadaptabilityVSAvoidcomputational complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by pre-training the neural network model on large corpora of teaching materials before deployment. The pre-trained model already possesses learned semantic representations and conceptual knowledge, enabling it to quickly adapt to specific analysis tasks without requiring extensive computational resources during actual use. This approach allows the system to achieve high adaptability across different subjects and teaching materials while reducing the computational complexity encountered during real-time processing.

3Measurement precision

If detailed concept-level analysis is performed on learner submissions, then the feedback quality and personalization improve, but the processing time and computational resources increase

Engineering Contradiction:
Improvefeedback precisionVSAvoidprocessing time
Core Design Contradiction:

Solution Approach 1:

The patent extracts only the essential conceptual elements from learner submissions that are relevant to the specific question being analyzed. Rather than performing exhaustive analysis of all aspects of a submission, the system identifies and focuses on the key concepts that determine correctness and understanding. This extraction approach enables the system to provide high-precision, personalized feedback on conceptual gaps without requiring excessive processing time or computational resources on irrelevant details.

AI summary

A device and method for analyzing teaching materials using an auto-encoder is provided. The teaching material analysis device includes a data collection module configured to receive teaching material data including question data related to a predefined question, solution data for the corresponding answer, and submission data representing a user's problem-solving process. An analysis module generates analysis data based on at least one of the question data and the submission data, using the received teaching material data and submission data. The analysis module identifies requirement information by comparing question data and solution data, and determines deficiency information by analyzing differences between solution data and submission data using a pre-trained auto-encoder. An output module then outputs the analysis data as output data. The device enables accurate identification of concepts required to solve questions and concepts lacking in user responses, facilitating adaptive educational feedback through AI-driven conceptual analysis.
