Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If cellular carrier records are used to determine geographical location, then location information is obtained quickly, but accuracy is compromised due to errors in validation and signals analysis
Solution Approach 1:
The patent applies preliminary action by generating a nominal cellular wireless signal coverage map before validating carrier records. This pre-established map serves as a reference framework that enables accurate validation of device locations against expected coverage areas, thereby improving both measurement precision and reliability of location determination
Solution Approach 2:
The patent implements feedback by analyzing multiple factors including traffic loading, weather conditions, and operation logs to continuously refine and update the coverage map. This feedback mechanism ensures that the validation process accounts for dynamic conditions that affect signal coverage, maintaining high accuracy despite changing environmental factors
2Measurement precision
If a nominal coverage map is generated and multiple factors are analyzed to produce a time-specific map, then location accuracy is improved, but the process complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the validation process into distinct modules: generating the nominal coverage map, analyzing traffic loading factors, analyzing weather conditions, analyzing operation logs, and producing the time-specific map. This modular approach manages complexity by organizing multiple analysis functions into separate, manageable segments that can be executed systematically
Solution Approach 2:
The patent implements universality by creating a multi-functional validation system that simultaneously processes multiple types of data (signal coverage, traffic loading, weather, operation logs) through a unified framework. The coverage map serves as a universal reference that integrates various factors to validate location accuracy across different conditions and time periods

AI summary
A method of validating cellular device location record accuracy is intended to validate and refine cellular carrier records accuracy for investigation and litigation purposes. Records provided by a cellular carrier and other information are analyzed to validate or refine a possible and/or estimated location of a specified cellular device during a specified time frame. More specifically, the location of a specified radio communications transceiver cell site is verified, a nominal cellular wireless signal coverage map is produced, and various pieces of information regarding potential service disruptions during the specified time frame are analyzed in order to produce a more accurate coverage map during the specified time frame for the purpose of quantitatively defining probable or potential locations for the specified cellular device.
