An information processing apparatus that includes a behavior state detection sensor, a behavior pattern information generation unit, a behavior score calculation unit, and a behavior pattern identification unit, which generate and analyze behavior pattern information in a multidimensional space using parameters like date, time, and place to identify behavior patterns and scores, and distinguish between ordinary and extraordinary behaviors.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If behavior state information is collected and analyzed using existing technologies, then some behavior information can be obtained, but the accuracy and precision of identifying and differentiating behavior patterns remains insufficient

Engineering Contradiction:
Improvebehavior pattern identification accuracyVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent transforms behavior state information into a multidimensional space where each dimension represents a specific parameter (date, time, place, duration). This dimensional transformation enables more accurate behavior pattern identification by analyzing density distributions across multiple dimensions simultaneously, resolving the contradiction between measurement precision and device complexity.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The patent introduces density as a new parameter to characterize behavior patterns in multidimensional space. By calculating density values at different points and comparing them against thresholds, the system can accurately differentiate between ordinary and extraordinary behaviors without requiring overly complex device architectures.

Inventive Principle:
Principle #35Parameter changes

2Measurement precision

If multidimensional space analysis is implemented to improve behavior pattern identification, then identification accuracy improves, but computational complexity and processing requirements increase

Engineering Contradiction:
Improvebehavior pattern differentiation accuracyVSAvoidcomputational processing power
Core Design Contradiction:
Measurement precisionVSPower

Solution Approach 1:

The patent segments the multidimensional space into discrete regions and calculates density independently for each region. This segmentation approach allows the system to process behavior data in manageable chunks rather than computing across the entire multidimensional space at once, reducing computational power requirements while maintaining high identification accuracy.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements density thresholding to identify only significant behavior patterns. By setting thresholds and focusing computational resources on regions exceeding these thresholds, the system achieves accurate behavior differentiation without performing exhaustive computations across all possible patterns, thus optimizing power consumption.

Inventive Principle:
Principle #16Partial or excessive action
