Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If ID information from wireless base stations is utilized, then mobile phone terminals can identify base station moving paths, but the system cannot function in environments without wireless base stations
Solution Approach 1:
The system uses radio wave information from multiple sources including wireless base stations, wireless LAN access points, and other radio wave emitting devices to achieve universal location identification functionality across different environments, not relying solely on base station ID information
Solution Approach 2:
The system introduces radio wave information as an intermediary that can be obtained from various radio wave emitting devices, serving as a mediator between the mobile phone terminal and the environment, enabling location identification even when traditional base station ID information is unavailable
2Device complexity
If only limited radio waves from wireless base stations are utilized, then processing is simplified, but the ability to utilize surrounding radio waves is restricted
Solution Approach 1:
The system segments radio wave information into different types (base station ID information, wireless LAN access point information, other radio wave information) and processes each segment according to its characteristics, allowing comprehensive utilization while managing complexity through structured handling of different information types
3Ease of operation
If radio wave information from multiple sources is recorded and compared, then user convenience is improved, but information processing complexity increases
Solution Approach 1:
The system performs preliminary actions by recording radio wave information in advance during normal operations, building a database of radio wave characteristics before they are needed for location identification, which simplifies real-time processing and improves user convenience without excessive complexity

AI summary
Radio wave information is observed in a predetermined environment. Information related to the radio wave is compared to new radio wave information. In a case where a result of the comparison satisfies a predetermined condition, a user is provided with a predetermined function. In an embodiment, positional information showing a position where the radio wave information is acquired and a time stamp is recorded for comparison, and in a case where the newly acquired radio wave information is radio wave information corresponding to a suspicious-person, a warning is issued to a user. In an embodiment, in a case where predetermined pieces of home radio wave information are not detected within a predetermined period, a system is operated to manage a house.
