Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a dedicated wired communication circuit is used to transmit abnormality detection data, then the abnormality detection data can be transmitted reliably, but the device complexity increases and detection efficiency decreases
Solution Approach 1:
The patent merges the abnormality detection data transmission function with the existing wireless communication circuit. The abnormality detection unit's output is transmitted through the same wireless communication interface used for normal data communication, eliminating the need for a separate dedicated wired communication circuit while maintaining transmission reliability.
Solution Approach 2:
The wireless communication circuit is designed to serve multiple functions: both normal data communication and abnormality detection data transmission. By making the communication interface universal, the patent reduces device complexity while ensuring that abnormality data can be transmitted reliably alongside other communication tasks.
2Measurement precision
If a dedicated wired communication circuit is provided for each abnormality detection unit, then the detection precision is maintained, but the manufacturing cost and device complexity increase
Solution Approach 1:
Multiple abnormality detection units share a common wireless communication interface for data transmission. This merging approach maintains the detection precision of each individual unit while reducing manufacturing costs by eliminating redundant communication circuits.
Solution Approach 2:
The shared wireless communication interface serves all abnormality detection units, making the communication system universal. This reduces the number of components needed, simplifying manufacturing while preserving the ability of each detection unit to provide precise abnormality detection.
3Speed
If abnormality detection data is transmitted each time an abnormality is detected, then the detection response is timely, but the communication overhead and energy consumption increase
Solution Approach 1:
The system implements a feedback mechanism where the wireless communication unit transmits abnormality detection data only when the abnormality detection unit identifies an actual abnormal condition. This feedback-based approach ensures timely detection response while avoiding unnecessary communication and energy consumption during normal operation.
Solution Approach 2:
Instead of continuous transmission, the system uses periodic checking with event-driven transmission. The abnormality detection unit periodically monitors conditions and triggers transmission only when an abnormality occurs, reducing overall communication overhead and energy consumption while maintaining rapid response capability when needed.

AI summary
A beamformer integrated circuit includes: an abnormality detection circuit configured to detect presence or absence of an abnormality; and a storage region including a detection result storage region configured to store a detection result of the abnormality detection circuit. In a case where a first communication message for instructing to specify an address to read out information stored in the storage region is received, a second communication message including information read out from a region of the storage region, which is specified by the address, and abnormal state presence/absence information indicating presence or absence of occurrence of an abnormality based on the detection result stored in the detection result storage region is transmitted.
