Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for anti-collision management in production plants involving robots and humans are cumbersome, error-prone, and fail to accurately assess the risk of collisions, making it difficult to minimize damage from potential impacts.
Innovation Solution
A data processing system and method for simulating and handling anti-collision management in production plants, which includes simulating the robotic and human operations, determining collision hit indices for human body parts, and generating a collision damage map to predict and visualize potential collision severity, allowing for systematic planning and modification of production processes to avoid collisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional safety mechanisms are provided to reduce damage from robot-human collisions, then safety is improved, but the complexity of the system increases and the robot's operational flexibility decreases
Solution Approach 1:
The patent applies preliminary action by simulating robot and human operations in advance within a virtual environment to identify potential collision risks before actual deployment. The system pre-calculates collision hit indices and generates collision damage maps, allowing safety measures to be planned and optimized beforehand, thereby reducing the need for complex real-time safety mechanisms while maintaining high safety standards.
2Reliability
If the robot's and human's movements are timed to avoid all possible hits, then collision risk is reduced, but the system becomes overly complex due to the non-deterministic nature of human behavior
Solution Approach 1:
The patent uses copying by creating a virtual copy of the physical environment, robot, and human operations. This virtual model allows for repeated simulation and analysis of collision risks without affecting real-world operations. The system copies human movement patterns and robot trajectories in the virtual scene, enabling comprehensive risk assessment while keeping the actual system simple and flexible.
3Measurement precision
If comprehensive safety analysis is performed to accurately assess collision risks, then safety assessment accuracy is improved, but the time and computational resources required increase
Solution Approach 1:
The patent applies segmentation by dividing the collision risk assessment into distinct components: robot operation analysis, human operation analysis, collision event determination, and damage calculation. Each component is analyzed separately and systematically, allowing for comprehensive accuracy while managing computational complexity through structured breakdown of the overall assessment process.
