Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If motion data and line of sight data are recorded but not visualized, then data collection is complete, but efficient search for optimal procedures cannot be achieved
Solution Approach 1:
The patent creates visual copies (trajectories) of the original motion data and line of sight data. Instead of directly analyzing raw motion records, the system generates trajectory visualizations that represent the motion paths and line of sight directions, making the data accessible for efficient analysis and optimization of work procedures
Solution Approach 2:
The patent introduces trajectory visualization as an intermediary between raw motion data and procedure optimization analysis. The trajectory serves as a mediating representation that transforms complex motion records into visually interpretable paths, enabling efficient search for optimal procedures without losing original information
2Measurement precision
If detailed motion and line of sight data are collected, then analysis accuracy is improved, but data processing complexity increases
Solution Approach 1:
The patent creates simplified visual copies (trajectories) of detailed motion data. The trajectory representation maintains the essential spatial and temporal information needed for accurate analysis while presenting the data in a less complex, more visually accessible format that reduces processing burden
Solution Approach 2:
The patent transforms motion data into trajectory visualizations that add a spatial dimension to the analysis. By representing motion as visual paths in space rather than numerical sequences, the system enables more intuitive and efficient analysis of motion patterns and line of sight directions
