Segment Work Zone Monitoring for Multi-Axis Kinematics Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for monitoring multi-axis kinematics require complex and costly workspace modeling with large, comprehensive work zones and numerous protection zones, leading to inefficient use of space and increased computational effort.
Innovation Solution
The method involves assigning segment kinematics zones to individual segments of multi-axis kinematics, determining segment work zones based on intended movements, and configuring safety monitoring to check each segment separately, reducing the need for extensive protection zones and optimizing workspace dimensions dynamically.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a large, comprehensive work zone is defined for the entire multi-axis kinematics to ensure safety monitoring, then safety coverage is improved, but space utilization deteriorates and computational complexity increases
Solution Approach 1:
The patent divides the multi-axis kinematics into individual segments and defines separate work zones for each segment rather than a single comprehensive work zone. This segmentation allows each zone to be tightly fitted to the actual movement space of its corresponding segment, reducing unnecessary space while maintaining complete safety coverage for each component.
Solution Approach 2:
The patent applies different work zone definitions to different segments based on their specific movement characteristics and spatial requirements. Each segment receives a customized work zone that matches its local movement patterns, rather than applying a uniform large work zone to all segments, thereby optimizing space utilization while preserving safety monitoring effectiveness.
2Manufacturing precision
If numerous protection zones are added to restrict kinematics movement within the work zone, then safety precision is improved, but device complexity increases
Solution Approach 1:
The patent segments the safety monitoring task into individual segment-level work zone checks rather than requiring multiple protection zones. By monitoring each segment within its own dedicated work zone, the system achieves precise workspace control without the complexity of layering multiple protection zones, reducing the number of monitoring boundaries that must be maintained and checked.
3Adaptability or versatility
If manual modeling of work zones is performed by users, then adaptability to specific applications is improved, but ease of operation deteriorates due to high complexity
Solution Approach 1:
The patent enables the system to automatically generate segment work zones based on the kinematic definitions and movement parameters that are already provided for production planning. The system self-configures the safety monitoring zones without requiring manual user modeling, leveraging existing kinematic data to create appropriate work zones automatically, thus maintaining adaptability while dramatically simplifying operation.
4Volume of stationary object
If segment-specific work zones are defined instead of a general work zone, then space utilization is improved, but measurement and detection complexity increases
Solution Approach 1:
The patent segments both the kinematics and the monitoring task, assigning each segment its own dedicated work zone and monitoring check. This segmentation actually simplifies detection complexity compared to monitoring a single large comprehensive zone, because each segment can be independently monitored within its own boundaries without requiring complex interactions between multiple protection zones or segments.
