Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle safety systems do not effectively detect and respond to impaired vehicle operators due to drowsiness, distraction, illness, intoxication, or agitation, despite the presence of on-board computer systems and mobile devices that could mitigate such situations.
Innovation Solution
A system and method using infrared sensors and processors to monitor vehicle occupants, determine abnormal situations, and implement responses such as controlling vehicle operation, adjusting environmental conditions, or communicating with emergency services, based on occupant characteristics like skeletal and physiological data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If on-board computer systems and mobile devices are equipped in vehicles, then computing resources and communication capabilities are available, but these resources are not effectively used to detect and mitigate dangerous situations involving vehicle operators or passengers
Solution Approach 1:
The system enables the vehicle's own computer resources and sensors to automatically monitor and detect dangerous situations without requiring external intervention. The onboard system performs self-diagnosis and self-monitoring of operator condition, utilizing existing vehicle computing power for safety detection functions.
Solution Approach 2:
The onboard computer system is designed to perform multiple functions: it controls vehicle operations, monitors operator condition, detects dangerous situations, and communicates with emergency services. This multi-functional approach utilizes the existing computing resources for diverse safety-related tasks rather than requiring dedicated separate systems.
2Measurement precision
If infrared sensors are used to monitor vehicle occupants, then abnormal situations can be detected, but system complexity increases
Solution Approach 1:
The infrared sensors serve as intermediary devices that indirectly detect operator condition by measuring thermal radiation and physiological parameters. Rather than directly observing cognitive or emotional states, the system uses thermal signatures as intermediate indicators of drowsiness, stress, or medical emergencies.
Solution Approach 2:
The system replaces complex mechanical or manual monitoring methods with optical/infrared sensing technology. Instead of physical contact sensors or manual checks, the infrared sensors non-contactly detect physiological parameters through thermal radiation, simplifying the physical interaction while maintaining detection precision.

Function Achieved in This Case
Enhances vehicle occupant safety by detecting and responding to impaired operators, potentially preventing accidents by taking control of the vehicle or alerting emergency services when necessary.
Implementation Method 1
using one or more infrared sensors disposed within the vehicle to receive sensor data about the vehicle occupant
Data Source
AI summary
Methods and systems for monitoring vehicle occupants using infrared and other sensors are disclosed. The systems may use infrared sensor data to identify each vehicle occupant using biometric signatures (such as heartbeat or facial recognition). Vehicle occupant characteristics may be determined that include skeletal characteristics of the occupants. Further monitoring of the occupants using sensor data may occur until an abnormal situation is detected. Abnormal situations may include medical emergencies, driver impairment, security threats, or similar situations requiring correcting action. The system may then determine and implement an appropriate response to the abnormal situation. Such responses may include generating alerts, adjusting vehicle environmental controls, taking control of operation of the vehicle (such as an autonomous or semi-autonomous vehicle), or initiating wireless communication with an outside party, such as an emergency service.
