Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a terminal performs sensing tasks without verifying capability information, then the operation is simple and fast, but the sensing accuracy and reliability deteriorate
Solution Approach 1:
The system performs pilot sensing operations before actual sensing tasks to verify the capability information of terminals. This preliminary verification ensures that only terminals with confirmed sensing accuracy are selected for actual tasks, resolving the contradiction between maintaining high sensing accuracy and avoiding overly complex verification mechanisms.
Solution Approach 2:
The system establishes a feedback mechanism where capability information is verified through pilot sensing, and the results are used to select appropriate terminals for sensing tasks. This feedback loop ensures that sensing accuracy is maintained while the selection process remains systematic and manageable.
2Use of energy by moving object
If the terminal selects cooperative terminals without considering battery status, then the selection process is simpler, but the power efficiency and battery life deteriorate
Solution Approach 1:
The system incorporates battery status as a dynamic parameter in the terminal selection process. By monitoring and considering battery levels alongside sensing capability information, the system optimizes power efficiency while maintaining a structured selection mechanism that does not excessively increase complexity.
3Measurement precision
If pilot sensing is performed on all neighboring terminals, then the sensing accuracy verification is thorough, but the time consumption and power usage increase
Solution Approach 1:
Instead of performing pilot sensing on all neighboring terminals, the system selectively performs pilot sensing based on capability information and status parameters. This partial action approach verifies sensing accuracy sufficiently without unnecessarily increasing time consumption, resolving the contradiction between thorough verification and time efficiency.
4Adaptability or versatility
If the terminal performs all sensing tasks independently, then the system architecture is simpler, but the sensing versatility and adaptability deteriorate
Solution Approach 1:
The system enables terminals to perform multiple functions including both sensing operations and capability verification. By making terminals multi-functional, the system achieves versatile sensing adaptability across different task types while keeping the overall architecture relatively simple, as the same terminals perform multiple roles.
