Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If complex communication protocols and high-frequency communication are used for system synchronization, then synchronization precision can be improved, but device complexity and cost increase
Solution Approach 1:
The patent replaces complex communication protocols and high-frequency communication systems with a simpler pulse signal transmission mechanism. Instead of using sophisticated software-based synchronization protocols, the invention uses hardware-level pulse signals with built-in timing information that can be directly detected and processed, thereby achieving high synchronization precision while significantly reducing device complexity
Solution Approach 2:
The patent embeds timing information by copying the master clock signal through pulse transmission. Each device receives a copy of the synchronized timing signal with embedded timestamp information, allowing them to independently calculate synchronization without complex communication overhead, thus improving precision while maintaining simplicity
2Reliability
If complex synchronization protocols are implemented, then synchronization reliability can be improved, but system stability deteriorates due to increased complexity
Solution Approach 1:
The patent implements a self-service synchronization mechanism where each device independently processes received pulse signals using local timing circuits and algorithms. Devices autonomously calculate their synchronization status and adjust their operations without requiring complex inter-device coordination protocols, thereby enhancing both reliability and stability through decentralized, simple operations
Solution Approach 2:
The patent incorporates built-in error detection and recovery mechanisms in the pulse signal transmission. The signal structure includes redundant timing information and validation bits that allow devices to detect and correct errors before they affect synchronization, providing beforehand cushioning against potential failures while maintaining system stability through simple, robust signal processing
3Measurement precision
If high-frequency communication is used for synchronization, then synchronization precision can be improved, but cost increases
Solution Approach 1:
The patent uses simple, inexpensive pulse transmission signals instead of expensive high-frequency communication systems. The synchronization is achieved through basic digital pulse signals that can be generated and detected using standard, low-cost hardware components, thereby achieving adequate precision while dramatically reducing manufacturing costs
4Measurement precision
If specific communication protocols are required for synchronization, then synchronization precision can be improved, but adaptability across different module models and manufacturers deteriorates
Solution Approach 1:
The patent creates a universal synchronization interface based on standard digital pulse signals that can be implemented across different module models and manufacturers. The pulse transmission mechanism and timing extraction algorithm are protocol-agnostic and can work with various hardware platforms, achieving broad compatibility while maintaining synchronization precision through standardized signal processing
