Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current impairment detection systems in workplaces are inadequate in addressing human error caused by fatigue, illness, and stress, as they primarily focus on drug and alcohol impairment, leading to ongoing accidents.

Innovation Solution

A computer-implemented method and system that administers an alertness test on client electronic devices, using visual, audible, or physical disrupters to assess user alertness, and takes remedial actions such as logging, notification, or disabling equipment if the user's alertness is insufficient for the task at hand.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If traditional drug and alcohol testing is implemented, then impairment detection capability is improved, but coverage of actual impairment causes (fatigue, illness, stress) remains insufficient

Engineering Contradiction:

Improveimpairment detection capabilityVSAvoidcoverage of impairment causes

Core Design Contradiction:

Measurement precisionVSAdaptability or versatility

Solution Approach 1:

The system performs multiple types of impairment detection through a single integrated platform. It administers various alertness tests (visual, audible, cognitive) and conducts environmental monitoring to detect multiple impairment causes including fatigue, illness, stress, drug use, and alcohol use, making the system versatile across different impairment types

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If real-time alertness monitoring is implemented, then workplace safety is improved, but system complexity increases

Engineering Contradiction:

Improveworkplace safetyVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system is divided into separate functional modules: alertness test administration module, environmental monitoring module, data analysis module, and remedial action module. Each module performs a specific function, making the overall complex system manageable through segmentation of responsibilities and functions

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A computing device serves as an intermediary between the user and the remedial action system. The computing device administers tests, collects responses, analyzes data, and triggers appropriate remedial actions, simplifying the interaction while maintaining system reliability

Inventive Principle:

Principle #24Intermediary (Mediator)

3Measurement precision

If multiple types of disrupters are used in alertness tests, then alertness assessment accuracy is improved, but ease of operation decreases

Engineering Contradiction:

Improvealertness assessment accuracyVSAvoidease of operation

Core Design Contradiction:

Measurement precisionVSEase of operation

Solution Approach 1:

The system dynamically selects and adjusts the type of disrupter (visual, audible, or physical) based on the specific alertness test being administered and the user's response patterns. This dynamic adaptation maintains assessment accuracy while adjusting the interaction to remain user-friendly

Inventive Principle:

Principle #15Dynamics

AI summary

A method, computer program product, and computing system for administering an alertness test on a client electronic device to determine a result for a user, wherein the result is indicative of a level of alertness of the user. A location of the client electronic device is determined, thus defining a determined location. Remedial action is taken if the level of alertness of the user is insufficient for the user to perform a task at the determined location.
