Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single technical framework is used to address all usage scenarios, then device complexity is reduced, but adaptability to different usage scenarios and deployment scenarios deteriorates
Solution Approach 1:
The patent applies universality by designing a single technical framework that can perform multiple functions across different usage scenarios (eMBB, mMTC, URLLC) and deployment scenarios (frequency bands up to 100 GHz). The framework achieves this through configurable parameters and flexible resource allocation mechanisms that adapt the same core technology to diverse requirements without requiring separate specialized systems for each scenario.
2Productivity
If reduced cost per bit is implemented, then productivity improves, but reliability of service delivery deteriorates
Solution Approach 1:
The patent employs parameter changes by dynamically adjusting transmission parameters (such as modulation schemes, coding rates, and resource allocation) based on channel conditions and service requirements. This allows the system to optimize cost efficiency by using simpler, lower-cost transmission methods when conditions permit, while automatically switching to more reliable, higher-cost methods when service availability requirements demand it, thus resolving the contradiction between cost and reliability.
3Adaptability or versatility
If flexible use of frequency band is implemented, then adaptability improves, but spectral efficiency deteriorates
Solution Approach 1:
The patent applies dynamics by implementing dynamic frequency selection and resource allocation mechanisms that continuously adapt to changing spectrum availability and service demands. The system can flexibly allocate different frequency bands to different services based on real-time conditions, while using advanced signal processing techniques to maintain high spectral efficiency by optimizing resource utilization and minimizing waste across the flexible frequency band usage.
