Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If millimeter-wave communication is used in each robot station for decentralized control, then communication speed and transmission efficiency are improved, but signal interference between adjacent robot stations occurs leading to prolonged producing periods
Solution Approach 1:
The system performs preliminary detection of adjacent robot stations' communication periods and signal timing before actual communication occurs. By estimating these parameters in advance and updating them continuously, the system can proactively adjust its communication timing to avoid interference, thus maintaining high-speed communication without prolonging the producing period.
2Adaptability or versatility
If robot stations operate independently with decentralized control, then system flexibility and adaptability are improved, but clock period deviation occurs reducing production efficiency
Solution Approach 1:
The system implements feedback mechanisms where each robot station detects and estimates the producing period and signal timing of adjacent stations. This information is fed back to adjust the local clock timing, compensating for deviations and maintaining synchronization across the decentralized system, thereby preserving production efficiency while retaining flexibility.
3Area of stationary object
If robot stations are arranged closely for compact layout, then space utilization is improved, but signal interference between adjacent stations increases
Solution Approach 1:
The system dynamically changes communication parameters including timing and frequency based on detected adjacent station activity. By adjusting these parameters in real-time according to the estimated producing period and signal timing of neighboring stations, the system can maintain compact layout while minimizing signal interference through adaptive parameter optimization.
4Device complexity
If conventional decentralized control is used without interference detection, then system complexity is reduced, but producing period deviation occurs decreasing overall production efficiency
Solution Approach 1:
The system introduces an intermediary estimation function that detects and estimates the producing period and signal timing of adjacent robot stations. This intermediary mechanism mediates between independent decentralized control units, enabling them to coordinate their operations without requiring complex direct communication protocols, thus maintaining simplicity while improving overall production efficiency.

AI summary
A communication apparatus detects a radio signal from another communication apparatus which performs radio communication in another apparatus station, estimates a producing period and signal timing of the another apparatus station using the detected radio signal, determines, based on the detected radio signal, a communication apparatus which has transmitted the signal, and stores, in association with each other, the determined communication apparatus and the producing period and signal timing of the another apparatus station, wherein at least one of the stored producing period and signal timing of the other apparatus station is updated using the detected radio signal.
