Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a gateway or hardware/firmware changes are used for heterogeneous protocol communication, then protocol compatibility is improved, but device complexity and overhead increase
Solution Approach 1:
The patent creates a copy of the target protocol's signal characteristics by generating simulation waveforms that mimic the temporal and spectral properties of the second protocol. Instead of implementing the actual second protocol in hardware, the system generates synthesized signals that replicate its essential features, allowing first-protocol devices to communicate with second-protocol devices without modifying the physical hardware.
Solution Approach 2:
The system transforms communication parameters by adjusting waveform characteristics such as symbol duration, subcarrier spacing, and cyclic prefix length to match the target protocol's specifications. By dynamically changing these parameters in the simulation waveform generation process, the system achieves protocol compatibility while maintaining the original hardware configuration.
2Adaptability or versatility
If a gateway or hardware/firmware changes are used for heterogeneous protocol communication, then protocol compatibility is improved, but time and resource overhead increase
Solution Approach 1:
The system performs preliminary waveform simulation and optimization by pre-calculating and storing simulation waveforms in a lookup table before actual communication occurs. This advance preparation includes generating waveforms with optimal parameters for different protocol combinations, so that during runtime, the system can quickly retrieve and use pre-computed waveforms without real-time calculation delays.
Solution Approach 2:
By creating accurate copies of target protocol signals through simulation, the system eliminates the need for time-consuming protocol translation and gateway processing. The synthesized waveforms directly replicate the essential characteristics of the second protocol, enabling seamless communication without the time overhead associated with traditional gateway-based approaches.
3Measurement precision
If simulation waveform information is stored in a lookup table, then signal generation accuracy is improved, but memory usage increases
Solution Approach 1:
The patent segments the simulation waveform data into discrete, manageable entries in the lookup table, organized by protocol type and communication parameters. Each table entry contains pre-computed waveform characteristics for specific scenarios, allowing the system to store only essential data points rather than complete waveform representations. This segmentation enables efficient memory utilization while maintaining high signal generation accuracy through precise parameter matching.
