Solution Overview

Problem

Conventional techniques for inducing emotion recognition through electrical stimulation cause discomfort due to high intensity, leading to pain and stiffness, making it ineffective.

Innovation Solution

An emotion recognition inducing device with an electrical stimulation presentation unit, a perceptual response acquisition unit, and a control unit that adjusts the stimulation intensity based on feedback to ensure the stimulation is subliminal and imperceptible, preventing discomfort.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If high intensity electrical stimulation is applied to induce emotion recognition, then emotion recognition can be induced, but discomfort such as pain and stiffness occurs

Engineering Contradiction:

Improveemotion recognition inductionVSAvoiddiscomfort (pain and stiffness)

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent changes the intensity parameter of electrical stimulation from high (conventional) to low/subliminal (invention), transforming the stimulation into an imperceptible level that avoids discomfort while still inducing emotion recognition through subtle facial muscle activation

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent implements a feedback mechanism where the system monitors the recognizer's responses and adjusts the stimulation intensity accordingly, using acquired feedback to determine optimal intensity levels that induce emotion recognition without causing discomfort

Inventive Principle:

Principle #23Feedback

2Object-affected harmful factors

If subliminal intensity electrical stimulation is applied, then discomfort is avoided, but emotion recognition induction effectiveness may be reduced

Engineering Contradiction:

Improvediscomfort avoidanceVSAvoidemotion recognition induction effectiveness

Core Design Contradiction:

Object-affected harmful factorsVSReliability

Solution Approach 1:

The patent precisely optimizes the intensity parameter to a subliminal level that is below perceptual threshold yet sufficient to activate facial muscles and induce emotion recognition, achieving both comfort and effectiveness through careful parameter calibration

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The feedback mechanism allows the system to iteratively adjust and refine the subliminal stimulation intensity based on observed effects, ensuring that the lowest effective intensity is used to maintain both comfort and induction effectiveness
