Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wireless communication is used in a heterogeneous environment with multiple standards and frequency bands, then the versatility and application range are improved, but the stability and reliability of communication quality deteriorate due to environmental influences
Solution Approach 1:
The patent applies parameter changes by adjusting propagation model parameters based on the selected communication environment classification. The system changes parameters such as path loss exponent, antenna height, and frequency characteristics to match the specific environment type (e.g., indoor, outdoor, urban, rural), thereby maintaining communication quality stability across heterogeneous wireless environments
Solution Approach 2:
The patent introduces an intermediary classification mechanism that categorizes communication environments into distinct types based on structure data and propagation loss characteristics. This intermediary classification layer enables the system to select appropriate propagation models and parameters, bridging the gap between diverse wireless standards and stable communication quality
2Measurement precision
If propagation loss data is measured and acquired for accurate communication environment classification, then the measurement precision and design accuracy are improved, but the time and resources required for data acquisition increase
Solution Approach 1:
The patent applies preliminary action by pre-acquiring and storing propagation loss data for multiple communication environments before actual design needs arise. The system performs preliminary measurements and stores structure data with associated propagation loss characteristics, enabling rapid retrieval and classification without time-consuming real-time measurements
Solution Approach 2:
The patent uses copying by creating representative propagation loss data sets that capture the essential characteristics of different communication environments. Instead of measuring every specific location, the system creates copies or models of typical environment types (indoor, outdoor, urban, rural) that can be reused for classification and design purposes
