Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If RF performance standards are not defined for handheld UEs supporting FR2-2 band, then device complexity is reduced, but communication reliability deteriorates
Solution Approach 1:
The patent defines specific RF performance parameters (reference sensitivity, EIS spherical coverage) with precise numerical values and measurement conditions for handheld UEs in FR2-2 band. By establishing concrete parameter specifications, the patent resolves the contradiction by providing clear reliability criteria without excessive complexity.
Solution Approach 2:
The patent replaces complex empirical testing with standardized theoretical calculation models for RF performance evaluation. By using defined formulas and reference conditions, the patent achieves reliable communication guarantees without requiring complex measurement systems.
2Reliability
If RF performance standards are not defined for handheld UEs supporting FR2-2 band, then ease of manufacture is improved, but communication reliability deteriorates
Solution Approach 1:
The patent establishes RF performance standards before UE manufacturing begins. By defining reference sensitivity and EIS requirements in advance, manufacturers can design and produce devices that meet communication reliability requirements without complex manufacturing processes.
Solution Approach 2:
The patent uses standardized reference models and theoretical calculations instead of expensive complex measurement systems. This approach maintains communication reliability while simplifying manufacturing verification processes.
3Adaptability or versatility
If RF performance standards are not defined for handheld UEs supporting FR2-2 band, then device complexity is reduced, but compatibility deteriorates
Solution Approach 1:
The patent defines universal RF performance standards that apply to all handheld UEs in FR2-2 band regardless of specific implementation details. By establishing general reference sensitivity and EIS requirements, the patent ensures compatibility across different devices without creating overly complex device-specific standards.
Solution Approach 2:
The patent establishes standardized parameter definitions (reference sensitivity, EIS spherical coverage) that provide compatibility criteria. These parameter specifications enable different UEs to interoperate reliably while maintaining clear, manageable standard complexity.
