Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If serial processing is used for communication and calculation processes, then system simplicity is maintained, but delay increases
Solution Approach 1:
The patent merges communication and calculation processes into a unified parallel execution framework. The communication device and calculation device operate simultaneously on different frequency bands, combining previously sequential operations into a single integrated process that reduces overall delay while managing system complexity through coordinated control.
Solution Approach 2:
The patent introduces a frequency band dimension to enable parallel processing. By assigning different frequency bands to communication and calculation operations, the system transitions from temporal sequencing to spatial-frequency parallelism, allowing both processes to execute concurrently without interference.
2Loss of time
If parallel processing of communication and calculation is implemented, then delay is reduced, but channel fluctuation resistance deteriorates
Solution Approach 1:
The patent implements feedback mechanisms where the communication device monitors channel conditions and adjusts transmission parameters accordingly. Quality determination results are fed back to optimize the parallel processing, allowing the system to maintain reliability despite channel fluctuations while benefiting from reduced delay.
Solution Approach 2:
The patent employs dynamic resource allocation and adaptive processing where the system can adjust the degree of parallelism and resource distribution based on real-time channel conditions. This dynamic approach allows optimization of both delay and reliability under varying network conditions.
3Productivity
If frequency band resources are allocated separately for calculation and communication, then processing can be optimized, but resource usage efficiency decreases
Solution Approach 1:
The patent creates a multi-functional frequency band allocation system where the same frequency infrastructure serves both communication and calculation purposes. The channel superposition capability allows the system to perform multiple functions (data transmission and computation) using overlapping spectral resources, improving overall resource usage efficiency while maintaining processing optimization.
