Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wireless communication is used in a heterogeneous environment with multiple frequency bands and standards, then the versatility and applicability of wireless communication is improved, but the stability and reliability of communication quality deteriorates due to environmental influences
Solution Approach 1:
The patent updates parameters of propagation models based on measured radio wave intensity data across multiple frequency bands. By adjusting propagation model parameters to match actual environmental conditions, the system maintains accurate propagation loss estimation despite environmental variations, thus preserving communication quality stability while supporting multiple standards
Solution Approach 2:
The patent implements a feedback mechanism where measured radio wave intensity data from the environment is used to update propagation model parameters. This closed-loop approach allows the system to adapt to environmental changes and maintain accurate propagation loss estimation, resolving the contradiction between versatility and reliability
2Measurement precision
If propagation model parameters are updated based on measured data to improve estimation accuracy, then the precision of propagation loss estimation is improved, but the complexity of the system increases due to additional measurement and processing requirements
Solution Approach 1:
The patent enables the propagation model to self-update using measurement data collected from the actual environment. The system automatically adjusts its own parameters based on measured radio wave intensity, eliminating the need for manual parameter calibration and reducing operational complexity while maintaining high estimation accuracy
