Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If analog signals are converted into digital data and stored in a data server connected by network, then measurement data can be transmitted and accessed remotely, but processing at high-speed cycles of at least the network speed becomes difficult
Solution Approach 1:
The system divides the measurement functionality into independent modular units (first measurement unit, second measurement unit, etc.), each capable of autonomous high-speed processing. This segmentation allows local units to perform rapid measurements without being bottlenecked by network transmission speeds, while still enabling remote access to the distributed measurement capabilities.
Solution Approach 2:
Measurement patterns are acquired and prepared in advance via the network before actual high-speed measurement begins. The control unit receives and stores measurement patterns beforehand, so that when measurement starts, the system can immediately execute high-speed cycles without waiting for real-time network instructions, thus achieving both remote configurability and high-speed processing.
2Adaptability or versatility
If a universal timer is used to synchronize multiple measurement instruments, then synchronization can be implemented, but high-precision synchronization becomes difficult
Solution Approach 1:
A central control unit acts as an intermediary that receives measurement patterns via network and distributes synchronized control signals to multiple measurement units. This intermediary coordinates the timing and synchronization of all measurement units, achieving high-precision synchronization that neither universal timers nor direct network communication can provide alone.
3Adaptability or versatility
If communication via network is used to synchronize measurement instruments, then coordination between instruments can be achieved, but processing at high-speed cycles dependent on network speed becomes difficult
Solution Approach 1:
The system extracts the high-speed measurement functionality from network-dependent operations. Measurement units perform high-speed local measurements independently of network speed, using pre-acquired measurement patterns. The network is used only for configuration and pattern transfer, not for real-time measurement coordination, thus eliminating network speed as a bottleneck for high-speed processing.
4Reliability
If entire measurement apparatuses are replaced upon sensor failure, then system reliability can be maintained, but system complexity and cost increase
Solution Approach 1:
The measurement system is divided into independent modular units (first measurement unit, second measurement unit, etc.), each with its own sensor and processing capability. When a sensor fails, only the specific measurement unit containing that sensor needs to be replaced or repaired, rather than replacing the entire measurement apparatus. This modular segmentation reduces replacement complexity and cost while maintaining system reliability.

AI summary
A high-speed converter includes at least one converter among a first converter for converting an analog signal into a digital value; a second converter for converting a digital value into an analog signal; a third converter for converting an electrical signal into a digital signal; and a fourth converter for converting a digital signal into an electrical signal, and causes the at least one converter to operate by a method based on information acquired via a network.
