Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current worksite risk analysis and documentation systems lack standardization and efficiency in calculating ergonomic risks and physical demands, making it difficult for companies to identify and mitigate hazards effectively, particularly for new hires and return-to-work candidates.
Innovation Solution
A video-based system that allows users to upload and analyze video data from cameras or mobile devices to document physical demands and ergonomic risks, using a standardized database to categorize tasks by DOT classification levels and generate reports that include priority rankings, injury costs, and recommended solutions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual documentation methods are used for ergonomic risk analysis, then flexibility in customization is maintained, but standardization and efficiency of risk calculation are compromised
Solution Approach 1:
The system segments the risk analysis process into distinct modules: video upload module, image capture module, task identification module, DOT classification module, and report generation module. Each module handles a specific aspect of the analysis, enabling standardized calculations while maintaining system organization and manageability.
Solution Approach 2:
The system introduces an intermediary database layer that stores standardized task definitions, DOT classification criteria, and ergonomic risk factors. This intermediary structure enables consistent risk calculations across different users and applications without requiring complex real-time computation logic in the interface layer.
2Loss of information
If comprehensive video analysis is implemented to document all physical demands, then documentation completeness is improved, but time and resource requirements increase
Solution Approach 1:
The system performs preliminary actions by pre-defining task categories, DOT classification levels, and ergonomic risk factors in a database before actual analysis. During video analysis, the system matches observed activities against these pre-defined categories, significantly reducing analysis time while maintaining comprehensive documentation of physical demands.
Solution Approach 2:
The system uses image frames captured from video as representative copies of physical activities. Instead of analyzing continuous video data, the system selects key frames that capture essential physical demands, maintaining documentation completeness while reducing processing time and resource requirements.
3Measurement precision
If detailed DOT classification levels are calculated for each task, then measurement precision of physical demands is improved, but device complexity and computational requirements worsen
Solution Approach 1:
The system changes parameters by using pre-established DOT classification criteria and ergonomic risk factors stored in the database. Instead of calculating complex physical models in real-time, the system matches observed tasks against predefined parameter sets (DOT levels, risk factors, weight categories), achieving precise classification with minimal computational complexity.
4Reliability
If standardized terminology and methods are implemented for physical demands, then reliability of risk assessment is improved, but ease of operation and user flexibility deteriorate
Solution Approach 1:
The system implements universal DOT classification standards and ergonomic risk factors that can be applied across multiple industries and task types. The standardized database structures enable consistent risk assessment reliability while the flexible interface allows users to adapt the system to their specific operational contexts through configuration rather than customization.
