Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If photoelectric sensors are placed close to the production line for monitoring, then measurement precision is improved, but reliability deteriorates due to misalignment, contamination, and maintenance issues
Solution Approach 1:
The patent extracts the monitoring function from the production line environment by placing cameras overhead, separating the sensing mechanism from the contaminated zone. This allows accurate object tracking without exposing sensors to misalignment and contamination risks inherent in close-proximity placement
Solution Approach 2:
The system introduces an intermediary processing layer (AI/ML algorithms) that analyzes images from overhead cameras. This mediator enables precise object detection and tracking without requiring physical proximity sensors to the production line, thus maintaining measurement precision while improving reliability
2Productivity
If sensors are placed close to the production line for real-time monitoring, then productivity is improved through real-time control, but loss of time increases due to frequent maintenance and downtime
Solution Approach 1:
By extracting sensors from the production line environment and placing them overhead, the system eliminates the need for frequent maintenance and adjustments, reducing downtime while maintaining real-time monitoring capabilities for continuous productivity improvement
Solution Approach 2:
The patent replaces mechanical/photoelectric sensors with overhead imaging systems and AI/ML processing. This substitution eliminates mechanical wear, alignment issues, and contamination problems, thereby reducing maintenance downtime while preserving real-time productivity monitoring
3Device complexity
If traditional sensors are used for object tracking, then device complexity is reduced, but measurement precision deteriorates when objects change appearance during production
Solution Approach 1:
The patent replaces simple photoelectric sensors with overhead cameras and AI/ML algorithms. Although this increases device complexity, it dramatically improves measurement precision by enabling accurate object tracking even when appearance changes occur during the production process
Solution Approach 2:
The system changes the detection parameters from fixed photoelectric thresholds to dynamic AI/ML-based image analysis. This allows the system to adapt to appearance changes in objects during production, maintaining high tracking precision despite increased computational complexity
Data Source
AI summary
Systems for tracking objects in a production process and controlling aspects of the production process utilize images from a plurality of cameras positioned above or around various locations of the production process, which transmit images to a server, in various embodiments. The server uses machine learning or artificial intelligence to locate and track the objects within the fields of view of the various cameras, and then control production process aspects in response. Other embodiments may be described and/or claimed.
