Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the application system generates and manages synchronization signals for multiple sensors, then the system can achieve coordinated operation of multiple sensors, but the processing load and complexity of the application system increases significantly
Solution Approach 1:
The patent divides the synchronization signal management function into separate modules: a synchronization signal generation unit within the sensor system and a control device that manages multiple sensors. This segmentation transfers the processing burden from the application system to dedicated synchronization modules, reducing application system complexity while maintaining multi-sensor coordination capability.
Solution Approach 2:
The patent introduces a control device as an intermediary between the application system and multiple sensors. This control device handles the generation and distribution of synchronization signals, acting as a mediator that simplifies the application system's interface while enabling coordinated operation of multiple sensors through centralized synchronization management.
2Adaptability or versatility
If the number of sensors is increased to expand system functionality, then the system can perform more comprehensive measurements, but the management of synchronization signals becomes more difficult and error-prone
Solution Approach 1:
The patent implements a universal synchronization signal generation unit that can manage multiple sensors through a standardized interface. This unit generates synchronization signals that can be distributed to any number of sensors, providing a multi-functional solution that simplifies signal management regardless of the number of sensors deployed, thereby maintaining ease of operation while expanding system functionality.
3Speed
If the application system performs high-speed real-time processing of synchronization signals, then the system can maintain precise timing coordination, but the system becomes less flexible when system changes occur
Solution Approach 1:
The patent implements a dynamic synchronization management architecture where the control device can adaptively generate and distribute synchronization signals based on the current system configuration. The system can dynamically add or remove sensors and the control device adjusts the synchronization signal distribution accordingly, maintaining precise timing coordination while providing flexibility for system changes without requiring complete reconfiguration.
