Solution Overview

Problem

Conventional methods for indicating characteristics of problems and problem sets based on multiple concepts and chapters provide only simplified information, making it difficult to obtain precise feedback and analyze the overall characteristics of complex problem sets, such as college scholastic ability tests, which can have varying characteristics from year to year.

Innovation Solution

A method that determines the characteristics of each problem by attributes and correlations between them, visualizing these characteristics as points and lines on a screen, allowing for precise indication and visualization of problem and problem set characteristics, with varying appearances based on frequency of attribute accumulation and answer correctness.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If problems based on multiple concepts and chapters are simply indicated by the last learned concept or chapter, then the indication method is simple and easy to implement, but the information provided is simplified and imprecise, making it difficult to obtain accurate feedback on learner weaknesses

Engineering Contradiction:

Improveease of indication methodVSAvoidprecision of problem characteristic information

Core Design Contradiction:

Ease of manufactureVSMeasurement precision

Solution Approach 1:

The patent segments the indication of problem characteristics by representing each concept and chapter as a separate node in a knowledge map, rather than providing a single simplified label. This allows multiple concepts and chapters to be individually identified and visualized, enabling precise tracking of which specific areas a learner struggles with while maintaining an organized, manageable structure.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent transitions from one-dimensional simple text indication to two-dimensional visual representation using a knowledge map with nodes and connections. This dimensional change allows simultaneous display of multiple concepts and chapters and their relationships, providing both comprehensive information and visual ease of understanding.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Ease of operation

If a simple list of concepts and chapters is provided for problems, then the information is easy to process, but learners only obtain fragmentary information and cannot easily note overall characteristics of a problem set

Engineering Contradiction:

Improveease of information processingVSAvoidcompleteness of problem characteristic information

Core Design Contradiction:

Ease of operationVSLoss of information

Solution Approach 1:

The patent merges individual concept and chapter nodes into a unified knowledge map structure that displays both detailed individual characteristics and overall problem set patterns. This combination allows learners to see both specific concept relationships and aggregate trends across multiple problems simultaneously, preventing information loss while maintaining ease of processing.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The knowledge map serves multiple functions: it provides detailed concept information for individual problems, shows relationships between concepts, and enables aggregation to reveal overall problem set characteristics. This multi-functionality allows the same visual structure to support both detailed analysis and broad pattern recognition.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Device complexity

If prior art analysis methods are used on problem sets like college scholastic ability tests, then the analysis process is simple, but the reliability is low because varying test characteristics year to year cannot be accurately captured

Engineering Contradiction:

Improvecomplexity of analysis methodVSAvoidreliability of problem set characteristic analysis

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The patent implements a dynamic knowledge map that can adapt to varying problem set characteristics across different years and tests. The system automatically adjusts the visualization based on the specific concepts and chapters present in each problem set, allowing accurate capture of year-to-year variations while maintaining a consistent analytical framework.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes the parameters of analysis by using visual node attributes (such as size, color, or position) to represent different characteristics of problems and their frequency of occurrence. This parameter transformation enables reliable detection of patterns and variations in problem set characteristics that would be difficult to capture with simple text-based analysis.

Inventive Principle:

Principle #35Parameter changes
