Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Difficulty of detecting and measuring
If position information is obtained using transmission devices that send out identification signals, then position detection capability is improved, but measurement precision deteriorates due to radio wave interference causing incorrect position information
Solution Approach 1:
The system pre-stores attribute information and thresholds for transmission devices before position detection occurs. When position information is obtained, the pre-stored thresholds are immediately applied to correct any errors caused by radio wave interference, eliminating the need for real-time analysis and enabling rapid correction of inaccurate data
Solution Approach 2:
The system establishes a feedback mechanism where obtained position information is continuously compared against pre-stored attribute information and thresholds. Incorrect position data is identified and corrected by referencing the feedback from threshold comparisons, ensuring that displayed position information accurately reflects actual device locations despite interference
2Measurement precision
If position information is corrected using pre-stored attribute information and thresholds, then measurement precision is improved, but device complexity increases due to additional storage and processing requirements
Solution Approach 1:
Attribute information and thresholds are pre-stored in the system before operation begins. This preliminary preparation eliminates the need for complex real-time analysis and calculation, reducing processing complexity while maintaining high measurement precision through simple threshold-based correction
Solution Approach 2:
The system transforms complex position verification problems into simple parameter comparisons by using pre-defined thresholds. Instead of analyzing complex radio wave interference patterns in real-time, the system simply compares obtained position data against stored threshold parameters, significantly reducing computational complexity

AI summary
An information processing apparatus for providing position information of a transmission device that sends out a signal including identification information of the transmission device, includes a processor, in communication with a memory, executing a process including storing in one or more storages an identification information of the transmission device in association with an attribute information, a threshold corresponding to the attribute information for each one of the attribute information, and the position information of the transmission device in association with the identification information of the transmission device, correcting the position information using the stored attribute information or the threshold stored in the one or more storages, and displaying on a display the corrected position information.
