Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for systems and methods that provide personalized, real-time guidance to users about unsafe environmental conditions, such as hazardous road conditions, particularly for individuals who may approach dangerous situations unaware, including those with visual impairments or physical disabilities.
Innovation Solution
A wearable environmental monitoring system that includes sensors and feedback components integrated into articles of apparel, which detect environmental hazards and alert users through audio or haptic feedback, utilizing a system controller and machine-readable media to process data and generate alerts based on the user's proximity to unsafe conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional environmental monitoring systems are used, then hazard detection capability is provided, but real-time personalized guidance and early warning to approaching users is not achieved
Solution Approach 1:
The system implements a feedback loop where sensors detect environmental hazards, the processor analyzes the data to determine unsafe conditions, and feedback components provide real-time alerts to users. This closed-loop feedback mechanism enables continuous monitoring and immediate personalized guidance to individuals approaching hazards, transforming static hazard detection into dynamic real-time warning.
Solution Approach 2:
The wearable device serves as an intermediary between the environmental hazard and the user. It includes sensors to detect hazards, a processor to interpret data, and feedback components to communicate warnings. This intermediary system bridges the gap between environmental conditions and user awareness, providing personalized real-time guidance that neither traditional monitoring systems nor human perception alone can achieve.
2Ease of operation
If wearable sensors are integrated into articles of apparel, then real-time hazard detection and alert capability is achieved, but device complexity increases
Solution Approach 1:
The system merges multiple functional components into a single wearable article of apparel. Sensors for detecting environmental hazards, processors for analyzing data, feedback components for providing alerts, and power sources are all integrated into one unified wearable device. This consolidation reduces the number of separate systems needed while maintaining real-time hazard detection and alert capabilities.
Solution Approach 2:
The wearable article of apparel serves multiple functions simultaneously: it detects environmental hazards through integrated sensors, processes and analyzes data to identify unsafe conditions, provides real-time alerts through feedback components, and tracks user movement to determine proximity to hazards. This multi-functionality reduces the need for separate specialized devices while comprehensive safety monitoring.
3Reliability
If multiple sensors and feedback components are integrated into wearable apparel, then comprehensive hazard detection and personalized guidance is provided, but power consumption increases
Solution Approach 1:
The system employs periodic sampling of environmental conditions rather than continuous monitoring. The processor evaluates sensor data at intervals to determine if unsafe conditions exist, and the feedback components provide alerts only when hazards are detected. This periodic operation reduces power consumption compared to continuous active monitoring while maintaining comprehensive hazard detection capability.
Solution Approach 2:
The wearable system includes a rechargeable battery that provides power to all components. The system is designed to be self-contained and self-powered, with the battery managing energy distribution to sensors, processors, and feedback components. This self-service power management enables comprehensive hazard detection while controlling overall power consumption through efficient energy utilization.

AI summary
The disclosed wearable device systems include several features for alerting and guiding persons who are approaching or near to potentially hazardous or high-risk conditions in their nearby environment. Sensor data from wearable devices (also referred to herein as “wearables”) are used to determine the presence of various unsafe environmental conditions and phenomenon, including dangerous terrain or other unusual conditions. The wearable would be used to warn a person, for example via auditory or haptic-based feedback, if the person is about to encounter an unsafe condition. In particular, the proposed systems can be of great benefit to the visually impaired, those persons with physical disabilities, or persons otherwise vulnerable to particular environmental conditions.
