Solution Overview

Problem

Patients with generalized mental arousal disorders face challenges in regulating their mental arousal levels, as traditional therapies often rely on therapist guidance and may not provide effective, personalized, or convenient methods for managing stress and anxiety.

Innovation Solution

A system utilizing sensors and a virtual reality environment with a machine learning controller that acquires bioelectric signals to determine mental arousal scores, adjusting virtual objects and stimuli to help subjects regulate their arousal levels, including personalized feedback and audio guidance to promote relaxation or increased alertness.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional therapy methods are used, then therapist guidance is provided, but the therapy lacks personalization and convenience

Engineering Contradiction:
Improvepersonalization of therapyVSAvoidtherapy system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system enables patients to self-regulate their mental arousal levels through automated bioelectric signal monitoring and virtual reality-based interventions. The machine learning model processes physiological data and delivers personalized therapy without requiring continuous therapist intervention, making the therapy self-administered while maintaining high personalization.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system dynamically adjusts therapy parameters based on real-time bioelectric signals (such as heart rate variability, skin conductance). The virtual reality environment and stimulation protocols are automatically modified according to measured physiological parameters, enabling adaptive personalization without manual therapist adjustment.

Inventive Principle:
Principle #35Parameter changes

2Measurement precision

If real-time bioelectric signal monitoring is implemented, then objective arousal measurement is achieved, but system complexity increases

Engineering Contradiction:

Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system uses multi-functional wearable sensors that simultaneously capture multiple bioelectric signals (ECG, GSR, temperature) with a single device. This universal sensing approach achieves comprehensive physiological monitoring without proportionally increasing system complexity, as one sensor suite serves multiple measurement functions.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

A machine learning model serves as an intermediary that automatically processes complex bioelectric signals and translates them into actionable arousal level assessments. This intermediary layer simplifies the connection between raw sensor data and clinical decision-making, reducing the complexity burden of real-time signal processing.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If virtual reality environment with dynamic stimuli is used, then personalized arousal regulation is achieved, but computational requirements increase

Engineering Contradiction:
Improvestimulus customization capabilityVSAvoidcomputational energy consumption
Core Design Contradiction:
Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The virtual reality environment presents stimuli in periodic cycles with varying intensity and duration. The system alternates between different stimulus types (visual, auditory, haptic) in structured sequences, enabling comprehensive arousal regulation while managing computational load through time-based segmentation of processing tasks.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The machine learning model pre-processes and categorizes bioelectric signals before they reach the virtual reality stimulus generation module. By preparing arousal level assessments in advance, the system reduces real-time computational requirements for stimulus customization, enabling personalized regulation with lower instantaneous energy consumption.

Inventive Principle:
Principle #10Preliminary action
