Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple wireless communication devices perform simultaneous communication to increase communication efficiency, then communication throughput is improved, but reception properties deteriorate due to varying transmission power precision among devices
Solution Approach 1:
The system segments wireless communication devices into different groups based on their transmission power precision characteristics. Devices with high precision form one group while devices with low precision form another group, allowing each group to be scheduled independently to maintain reliable reception properties while enabling simultaneous communication across groups.
Solution Approach 2:
The system applies different scheduling strategies to different device groups based on their local characteristics. High-precision devices can use aggressive scheduling with higher power levels, while low-precision devices use conservative scheduling with lower power levels, optimizing overall system performance while maintaining reception reliability for each group.
2Reliability
If transmission power is increased to ensure received signal intensity, then communication reliability is improved, but signal saturation occurs and communication quality deteriorates
Solution Approach 1:
The system dynamically changes transmission power parameters based on device precision characteristics and channel conditions. Instead of using fixed high power for all devices, the system adjusts power levels individually for each device group, preventing saturation while maintaining reliable reception through adaptive parameter optimization.
3Adaptability or versatility
If transmission power precision varies among wireless communication devices, then device compatibility is improved, but reception property degradation occurs leading to communication failures
Solution Approach 1:
The system segments devices with varying transmission power precision into distinct groups, allowing each group to operate within its capability range. This segmentation maintains device compatibility by accommodating different precision levels while preventing reception property degradation through group-specific scheduling and power control.
