Solution Overview

Problem

Existing monitoring systems for detecting abnormalities in individuals, such as in a learning environment, face inaccuracies due to varying behavioral and physiological characteristics among individuals and over time, leading to unsatisfactory accuracy and reliability.

Innovation Solution

A system comprising imaging devices and an abnormality detection server that processes imaging signals to generate identity data, detect physical or behavioral characteristics, and identify abnormalities based on individual profiles and context data, using a biometric profile management system to compare detected characteristics against personal benchmarks rather than universal standards.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If monitoring devices compare extracted behavioural or physical features with predetermined ranges representing normal features, then the system can automatically detect abnormalities, but the accuracy and reliability are unsatisfactory due to varying individual characteristics

Engineering Contradiction:
Improveabnormality detection reliabilityVSAvoidabnormality detection accuracy
Core Design Contradiction:
ReliabilityVSMeasurement precision

Solution Approach 1:

The system performs preliminary actions by capturing and storing baseline behavioural and physical feature data for each individual during a training period before abnormality detection begins. This preliminary data collection enables the system to establish personalized reference profiles that account for individual variations, thereby improving detection accuracy and reliability when comparing current features against these personalized baselines.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system implements feedback mechanisms where detected abnormalities are reviewed and confirmed by educators or monitors, and this feedback is used to refine and update the individual's baseline profile. The system continuously learns from feedback loops, adjusting its understanding of normal behavior for each individual, which progressively improves detection accuracy and reduces false positives.

Inventive Principle:
Principle #23Feedback

2Ease of operation

If universal predetermined ranges are used for abnormality detection, then the system is simple to operate, but it fails to account for individual variations in behavioural and physiological characteristics

Engineering Contradiction:
Improvesystem operation simplicityVSAvoiddetection reliability for diverse individuals
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system automatically performs preliminary characterization of each individual during a training period, capturing baseline data without requiring manual configuration. This automated preliminary action maintains ease of operation while building personalized profiles that improve detection reliability for diverse individuals.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system dynamically changes the detection parameters from universal fixed ranges to individualized dynamic ranges based on each person's baseline characteristics. This parameter adaptation maintains operational simplicity from the user perspective while significantly improving detection reliability by tailoring criteria to individual norms rather than applying one-size-fits-all thresholds.

Inventive Principle:
Principle #35Parameter changes

3Productivity

If the system monitors multiple individuals simultaneously, then productivity increases, but the complexity of managing and comparing individual profiles increases

Engineering Contradiction:
Improvemonitoring throughputVSAvoidprofile management complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system segments the monitoring task by maintaining separate, independent baseline profiles for each individual rather than using a single unified assessment framework. This segmentation allows the system to process multiple individuals simultaneously through parallel operations, improving productivity while keeping the complexity manageable through modular profile management structures.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system implements self-service functionality where automated algorithms independently manage, compare, and update each individual's profile without requiring manual intervention. This automation handles the complexity of profile management across multiple individuals, enabling high productivity while keeping operational complexity low through intelligent self-management of the data structures.

Inventive Principle:
Principle #25Self-service
