Solution Overview

Problem

Intoxicated individuals often struggle to operate communication devices safely and make responsible decisions due to impaired fine motor skills and judgment, and are often unaware of their intoxication, leading to potential fatal consequences while driving or making regrettable phone calls.

Innovation Solution

A communication device and network node reconfiguration system that uses breath analysis or acoustic-phonetic analysis of speech patterns to determine the user's level of intoxication, enabling features such as disabling certain phone numbers, changing device settings, and redirecting calls to prevent unsafe actions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the user operates the communication device while intoxicated, then the user can make phone calls and communicate, but the user may make regrettable calls or attempt to drive with potentially fatal consequences due to impaired judgment and awareness

Engineering Contradiction:
Improveability to operate communication deviceVSAvoidsafety of operation
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system automatically detects intoxication through breath analysis or speech pattern analysis and autonomously reconfigures the communication device without requiring user action. The device monitors its own user's state and takes corrective action by disabling problematic features or enabling safety features, allowing the intoxicated user to continue basic communication while preventing harmful actions.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system continuously monitors the user's physical state through breath analyzers or speech analysis and provides real-time feedback by detecting changes in speech patterns (formants, pitch, articulation rate, vocal intensity, speech errors, response time, nonfluency, and speech quality). This feedback loop enables the system to adapt the device configuration dynamically based on the user's current state.

Inventive Principle:
Principle #23Feedback

2Reliability

If the communication device is reconfigured to prevent unsafe actions by intoxicated users, then safety is improved, but the user's ability to operate the device and make calls is restricted

Engineering Contradiction:
Improvesafety of operationVSAvoidability to operate communication device
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system applies different operational restrictions to different functions of the communication device based on the user's state. Rather than completely disabling the device, it selectively restricts specific features (such as enabling additional prompts for text messages, inserting time delays, or blocking specific contacts) while allowing other functions to operate normally. This localized approach maintains safety while preserving essential communication capabilities.

Inventive Principle:
Principle #3Local quality

3Measurement precision

If breath analysis or speech pattern analysis is performed to detect intoxication, then the level of intoxication can be determined, but the device complexity and processing requirements increase

Engineering Contradiction:
Improvedetection accuracy of intoxicationVSAvoidanalysis system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system replaces complex mechanical breath analysis hardware with acoustic-phonetic analysis of speech patterns, which can be performed using existing microphone and processing capabilities. By substituting the detection mechanism with signal processing techniques that analyze formants, pitch, articulation rate, vocal intensity, speech errors, response time, nonfluency, and speech quality, the system achieves intoxication detection without requiring additional complex hardware components.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

Enables intoxicated users to safely operate communication devices, prevents regrettable calls, and provides an indication of intoxication level, thereby reducing risks associated with driving and improving decision-making.

Implementation Method 1

The determination is effected by performing a breath analysis of the user. In other words, a breath analyzer, such as a breathalyzer, is preferably included in the user's telephone in proximity to the microphone.

Methodology Applied
Scientific EffectBreath analysis:

Implementation Method 2

The determination can be acoustic-phonetic analysis of the voice utterance to determine the likelihood that the speaker has the target physical condition and/or a likely degree or severity of the target physical condition. The acoustic-phonetic analysis analyzes, with reference to a baseline utterance of the user one or more of a formant of the utterance, a pitch of the utterance, a speech and/or articulation rate of the utterance, a vocal intensity of the utterance
