Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing detection systems for accidents within moving bodies, such as vehicles, lack a specific method to accurately detect the pose, position, and behavior of passengers in relation to safety equipment, which is crucial for preventing falls and accidents.
Innovation Solution
A detection apparatus comprising an equipment information acquisition unit, a person information generation unit, and a detection unit that utilizes image analysis to determine the position of equipment and passengers, and detects danger states by analyzing the relative positional relationship between them, enabling accurate detection of potential accidents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Difficulty of detecting and measuring
If image analysis is used to detect passenger position and behavior, then detection capability is improved, but measurement precision is insufficient without specific achievement means
Solution Approach 1:
The detection system is segmented into multiple functional units: equipment information acquisition unit, person information generation unit, and detection unit. Each unit performs a specific task - acquiring equipment positions, generating person position information from images, and detecting danger states by comparing relative positions. This segmentation allows for precise detection of passenger position and behavior while maintaining overall system capability.
2Device complexity
If general detection methods are used, then device complexity is reduced, but reliability of danger state detection is insufficient
Solution Approach 1:
The system introduces an intermediary processing step - the person information generation unit that creates structured person position information from image data. This intermediary layer bridges the gap between simple image capture and reliable danger state detection, enabling accurate determination of relative positions between passengers and equipment without excessive system complexity.
3Measurement precision
If detailed position tracking is implemented, then detection accuracy is improved, but loss of information increases due to complex data processing
Solution Approach 1:
The system extracts only the essential information needed for danger state detection - the relative position between passenger and equipment. The person information generation unit generates focused position information from images, and the detection unit uses only this extracted positional data to determine danger states, avoiding unnecessary data processing and information loss.
