Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If acceleration data is transmitted from sensor to controller each time it is obtained, then data freshness is improved, but wireless communication standards cannot be satisfied due to excessive transmission frequency
Solution Approach 1:
The patent implements periodic batch transmission of acceleration data instead of continuous real-time transmission. The sensor controller accumulates acceleration data over multiple measurement cycles and transmits it periodically to the robot controller, thereby reducing transmission frequency to comply with wireless communication standards while maintaining acceptable data freshness for vibration suppression control.
Solution Approach 2:
The sensor controller performs preliminary data accumulation and packaging before transmission. By pre-processing and batching the acceleration data in advance, the system reduces the frequency of wireless transmissions while ensuring that the controller receives sufficient data for effective vibration suppression, thus balancing data freshness with communication standard compliance.
2Ease of operation
If wireless communication is used for data transmission, then ease of operation is improved, but data corruption or loss occurs during transmission
Solution Approach 1:
The patent implements a feedback mechanism where the robot controller monitors the quality and completeness of received acceleration data. When data corruption or loss is detected, the controller can request retransmission or use interpolation algorithms to reconstruct missing data, thereby maintaining data integrity while preserving the ease of wireless communication operation.
Solution Approach 2:
The system prepares for potential data transmission issues by implementing error correction codes and data validation protocols before transmission occurs. This preventive approach ensures that even if data corruption occurs during wireless transmission, the integrity of the acceleration data can be maintained through pre-established error handling mechanisms.
3Reliability
If header and footer data are added to satisfy communication standards, then communication compliance is improved, but transmission efficiency deteriorates
Solution Approach 1:
The patent merges multiple acceleration data points into single batch transmissions with shared header and footer information. By combining several data measurements into one transmission packet, the overhead of header and footer data is amortized across multiple data points, thereby improving transmission efficiency while still satisfying wireless communication standard compliance requirements.

AI summary
A robot system capable of effectively transmitting acceleration data from a wireless acceleration sensor to a robot controller. The acceleration sensor has a time series number adding part which adds a number representing time series of the acceleration data of the robot, a data set generating part which generates a data set including acceleration data in a plurality of periods of time, and a first wireless communication part which transmits the data set to the robot controller by radio. The robot controller has an acceleration data judging part which checks the time series number added to the acceleration data contained in the data set received by a second wireless communication part and judges as to whether the time series is correctly received, and a vibration suppression controlling part which carries out vibration suppression control for the robot based on the time series of the acceleration data.
