Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If traditional processing methods are used to manage disparate-rate data streams, then system complexity is reduced, but latency increases and processing efficiency deteriorates
Solution Approach 1:
The patent segments the processing of disparate-rate data streams by creating separate processing paths for different data rates. The system divides incoming data streams into multiple channels, each handled by dedicated processing logic, thereby reducing latency for time-critical streams while maintaining manageable complexity through modular organization.
Solution Approach 2:
The patent implements dynamic processing by allowing the system to adaptively adjust processing priorities and resource allocation based on real-time data rate requirements. The processing engine dynamically reconfigures data stream handling to minimize latency for high-priority streams while efficiently managing overall system complexity.
2Speed
If flexible processing control is implemented to minimize latency, then latency is reduced, but device complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-configuring processing parameters and establishing data stream priorities before actual processing begins. The system pre-allocates processing resources and sets up latency-minimization strategies in advance, enabling fast processing without requiring complex real-time decision-making that would increase control system complexity.
3Manufacturing precision
If disparate-rate data streams are processed together, then device complexity is minimized, but processing precision and control accuracy deteriorate
Solution Approach 1:
The patent applies local quality by assigning different processing characteristics to different data streams based on their specific rate requirements and priority levels. Each data stream receives customized processing treatment appropriate to its characteristics, thereby achieving high control precision for each stream while managing overall complexity through localized optimization rather than uniform complex processing.

AI summary
A system may include a processing engine and an analog-to-digital conversion interface subsystem communicatively coupled to the processing engine. The processing engine may be configured to process feedback data converted from analog feedback data to digital feedback data, wherein the feedback data includes a plurality of data stream sequences converted from the analog feedback data to the digital feedback data at a sample rate and based on processing of the feedback data, generate digital control signals for controlling a system under control. The analog-to-digital conversion interface subsystem may be configured to flexibly control the processing of the processing engine and the generation of digital control signals by the processing engine to minimize latency in the generation of the digital control signals due to processing of the processing engine.
