Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If ocean bottom electromagnetic acquisition stations are in direct communication with control terminal, then control and data transmission can be performed, but the structure becomes complicated due to requiring onboard interpretation mechanisms
Solution Approach 1:
The patent introduces a relay timing module as an intermediary device that handles command interpretation and timing functions. This module acts as a mediator between the control terminal and the ocean bottom electromagnetic acquisition station, allowing the station to receive simple trigger commands while the relay timing module performs the complex interpretation and coordination tasks, thus simplifying the station's structure while maintaining reliable control and data transmission
2Device complexity
If relay timing module is introduced to process stations before placement, then structure is simplified, but additional communication infrastructure is required
Solution Approach 1:
The patent combines multiple functions into the relay timing module, including command interpretation, timing control, and data management. By merging these functions into a single centralized module, the system reduces overall complexity even though it adds a communication component. The module handles multiple tasks that would otherwise require separate mechanisms in each acquisition station
