Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple buffering approach (double buffering, triple buffering, quad buffering) is used to address arrival time drifting, then signal drop/repeat bursts are prevented, but system latency increases and performance deteriorates
Solution Approach 1:
The patent implements dynamic period adjustment where the processing period is continuously adapted based on the actual arrival time of signals. The period-adjustment unit modifies the duration of each processing period dynamically to match the varying signal arrival intervals, allowing the system to maintain reliability without requiring multiple buffers to compensate for timing variations.
Solution Approach 2:
The system changes the parameter of processing period duration adaptively. By adjusting the period length according to actual signal arrival times, the system optimizes the balance between handling timing drift and minimizing latency, avoiding the need for fixed multiple buffering schemes that inherently increase delay.
2Reliability
If multiple buffering approach is used to track consecutive signals, then arrival time drifting is compensated, but device complexity increases
Solution Approach 1:
The patent replaces static multiple buffer structures with a dynamic period adjustment mechanism. Instead of maintaining multiple fixed buffers to handle timing variations, the system uses a single adaptive processing period that adjusts its duration based on signal arrival patterns, significantly reducing structural complexity while maintaining reliability.
Solution Approach 2:
The system manages timing variability by changing the period parameter dynamically rather than using multiple fixed buffers. This parameter-based approach simplifies the device structure while effectively compensating for arrival time drifting through adaptive timing control.
3Ease of operation
If fixed processing periods are used, then system operation is simple, but arrival time drifting causes signal drop/repeat bursts
Solution Approach 1:
The patent transitions from fixed to dynamic period operation. The period-adjustment unit automatically modifies processing period durations based on signal arrival times, maintaining operational simplicity while eliminating the reliability issues caused by fixed periods through adaptive timing adjustment.
Solution Approach 2:
The system incorporates feedback from signal arrival time measurements to adjust processing periods. The tracking unit monitors actual arrivals and feeds this information to the period-adjustment unit, creating a closed-loop system that maintains stability while keeping operation simple through automatic adaptation.
