Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If real-time analysis and validation is implemented during survey, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent introduces an intermediary system comprising a server and processing software that acts as a mediator between the measurement device and the surveyor. This intermediary performs real-time data validation, completeness checking, and analysis, thereby improving measurement precision without requiring the surveyor's device itself to become more complex. The complex processing functions are offloaded to the intermediary system.
Solution Approach 2:
The patent replaces manual mechanical analysis processes (performed by surveyors examining data after collection) with automated computational systems. The server-based software automatically validates measurements, checks data completeness, and provides real-time feedback, substituting human analytical effort with algorithmic processing that achieves higher precision without increasing the complexity of the field surveyor's equipment.
2Measurement precision
If multiple survey cycles are performed to ensure data completeness, then measurement precision is improved, but loss of time increases
Solution Approach 1:
The patent implements continuous feedback mechanisms where the system monitors measurement data in real-time, compares it against predefined completeness criteria, and immediately notifies the surveyor when additional measurements are needed. This feedback loop eliminates the need for multiple complete survey cycles by providing ongoing guidance, thereby achieving data completeness within a single survey pass and reducing total survey time.
Solution Approach 2:
The system performs preliminary validation and completeness checks continuously during data collection rather than waiting until the end of each survey cycle. By proactively identifying missing or insufficient measurements in real-time, the system guides the surveyor to complete necessary measurements immediately, preventing the need for repeated full survey cycles and reducing overall time loss.
3Measurement precision
If RF technician manually analyzes data on-site, then measurement precision is improved, but loss of time increases
Solution Approach 1:
The patent enables the measurement system to perform self-validation through automated algorithms that check data quality, validate measurements against environmental parameters, and assess completeness without requiring manual intervention from RF technicians. This self-service capability maintains high measurement precision through rigorous validation while eliminating the time-consuming manual analysis process.
Solution Approach 2:
The patent replaces the manual analytical process performed by RF technicians with automated computational algorithms running on a server. The system automatically validates measurement data, checks for anomalies, and determines data completeness, substituting human analytical time with rapid machine processing that achieves equivalent or superior validation precision without the time cost of manual review.
4Measurement precision
If comprehensive measurement data is collected to characterize RF environment, then measurement precision is improved, but loss of time increases
Solution Approach 1:
The patent implements real-time feedback that continuously monitors the quality and sufficiency of collected measurement data. The system compares incoming measurements against predefined criteria for adequate RF environment characterization and immediately indicates when sufficient data has been gathered. This feedback mechanism prevents both under-surveying (which would compromise precision) and over-surveying (which would waste time), optimizing the data collection process to achieve complete characterization in minimal time.
