Seat Vibration Sensing for Passenger Bleeding Volume Inference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems struggle to accurately infer the bleeding volume of passengers in accident scenarios involving movable bodies, particularly when internal bleeding is present.
Innovation Solution
An information processing device equipped with sensors to detect vibrations and infer bleeding volume based on heart rate and respiratory rate, along with a determining section to identify collision accidents, and a notifying section to alert the urgency level of injury.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If video data from imaging devices is used to infer passenger damage, then visual injury assessment is possible, but internal bleeding detection is insufficient
Solution Approach 1:
The patent introduces vibration sensors as intermediary devices that detect physiological signals (heart rate, respiratory rate) transmitted through the seat. These sensors act as mediators between the passenger's internal state and the external assessment system, enabling detection of internal bleeding without direct visual observation or invasive procedures.
Solution Approach 2:
The patent replaces the optical/mechanical imaging system with a vibration-based detection system. Instead of using cameras to visually assess injuries, the system uses vibration sensors to detect mechanical vibrations from the passenger's body, which are then processed to infer internal bleeding conditions.
2Measurement precision
If multiple sensors and inference functions are added to detect internal bleeding, then bleeding volume inference capability is improved, but device complexity increases
Solution Approach 1:
The patent makes the existing seat vibration sensor serve multiple functions: it detects both ordinary seat vibrations and physiological signals from the passenger. By analyzing different frequency components of the same sensor output, the system can infer heart rate, respiratory rate, and bleeding volume without requiring separate specialized sensors for each measurement.
Solution Approach 2:
The patent combines the detection of multiple physiological parameters (heart rate, respiratory rate, bleeding volume) into a single integrated system. The vibration sensor captures all these signals simultaneously, and the inference unit processes them together to provide comprehensive health assessment, reducing the need for multiple separate detection systems.

AI summary
An information processing device includes an obtaining section that obtains a detection signal from a sensor which is disposed in a seat of a movable body and which detects vibration transmitted to the seat from a passenger seated on the seat and an inferring section that infers a bleeding volume of the passenger on the basis of the detection signal obtained by the obtaining section.
