Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing accident report systems fail to provide information on the situation of vehicle occupants after an accident, making it difficult for external agencies to determine the need for emergency lifesaving activities.
Innovation Solution
An accident report system that includes an accident detection section, an information collection section, and an information report section, which collects and reports accident cause data before the accident and accident damage data after the accident, allowing for a determination of the occupant's situation and the necessity of emergency measures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the camera only captures images of the area forward of the vehicle before the accident, then the device complexity is reduced, but the information completeness about occupant situation deteriorates
Solution Approach 1:
The patent segments the information collection process into two distinct phases: pre-accident data collection (capturing forward area images and vehicle state data) and post-accident data collection (capturing occupant situation images and damage data). This segmentation allows the system to gather comprehensive information without requiring a single complex camera system to handle all scenarios simultaneously.
Solution Approach 2:
The system performs preliminary data collection before the accident occurs, storing vehicle state information and capturing forward area images in advance. This preliminary action ensures that critical data is preserved even if the camera system becomes inoperative after the accident, while the simplified pre-accident configuration reduces device complexity.
2Measurement precision
If the system collects both accident cause data and accident damage data, then the measurement precision of occupant situation is improved, but the loss of time for data processing increases
Solution Approach 1:
The system performs preliminary classification and organization of data into accident cause data and accident damage data during the data collection phase. By pre-organizing data according to its purpose and timing, the system reduces the computational burden during post-accident analysis, thereby minimizing data processing time while maintaining high measurement precision for occupant situation assessment.
Solution Approach 2:
The patent segments the collected data into distinct categories (accident cause data and accident damage data) with different collection timings and purposes. This segmentation allows external agencies to process only the relevant data subsets based on their specific needs, reducing overall data processing time while maintaining comprehensive and precise occupant situation assessment.
3Loss of information
If the camera captures images continuously before and after the accident, then the information completeness is improved, but the use of energy increases
Solution Approach 1:
The system employs periodic action by switching the camera operation mode based on the accident detection state. Before the accident, the camera captures images at lower frequency or only in specific conditions. After accident detection, the camera intensifies capture frequency specifically for occupant situation assessment. This periodic activation pattern ensures comprehensive information collection while minimizing energy consumption during normal operation.
Solution Approach 2:
The system performs preliminary data collection at reduced energy consumption levels before the accident occurs, capturing only essential forward area images and vehicle state data. After accident detection, the system activates higher energy consumption modes only when necessary for post-accident analysis. This preliminary action approach ensures information completeness while optimizing energy usage by avoiding continuous high-power operation.

AI summary
An accident report system for a vehicle includes an accident detection section to detect an accident; an information collection section to collect information; and an information report section to report the collected information to an external agency when the accident is detected. The information collection section differentiates the collected information before and after the detection of the accident such that (i) an accident cause data is collected before the detection of the accident to confirm an exterior outside of the vehicle and (ii) an accident damage data is collected after the detection of the accident to confirm an interior inside of the vehicle. The collection and report of the accident cause data and accident damage data permits the external agency to recognize states of the vehicle or states of an occupant of the vehicle before and after the detection of the accident.
