Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If pre-defined layout information and precise location of access control devices are required, then measurement precision and reliability of the security control system are improved, but device complexity and ease of manufacture deteriorate
Solution Approach 1:
The mobile communication device performs self-location by processing UWB signal properties to determine its own position within the secure control area without requiring external assistance or pre-defined layout information. The device automatically generates layout information based on its determined location, eliminating the need for manual configuration by installation personnel.
Solution Approach 2:
The system performs preliminary location determination of the mobile communication device within the secure control area before finalizing the layout information. By pre-determining the location through UWB signal processing, the system prepares the necessary spatial data in advance, enabling automatic generation of accurate layout information without requiring pre-defined configurations.
2Reliability
If pre-defined layout information is required, then reliability of access control is improved, but installation time and productivity deteriorate
Solution Approach 1:
The mobile communication device automatically determines its location and generates layout information without requiring installation personnel to manually define layouts or provide pre-defined spatial data. This self-service approach eliminates time-consuming manual configuration while maintaining reliable access control through accurate automatic location determination.
Solution Approach 2:
The system replaces manual mechanical configuration processes with automated electronic location determination using UWB signals. Instead of requiring installation personnel to physically measure and define layouts, the system uses electronic signal processing to automatically determine positions and generate layout information, significantly reducing installation time while maintaining reliability.
3Measurement precision
If access control devices require precise location calibration, then measurement precision is improved, but device complexity and ease of operation deteriorate
Solution Approach 1:
The mobile communication device performs self-location by processing UWB signal properties to automatically determine its position without requiring manual intervention or complex configuration procedures. The device autonomously generates layout information based on its determined location, making the process simple and intuitive for end users while maintaining high measurement precision.
Solution Approach 2:
The system changes the approach from requiring fixed pre-defined layout parameters to dynamically determining location parameters through UWB signal processing. By using signal properties such as time of flight and signal strength to calculate position, the system adapts to actual device locations without requiring manual parameter entry, simplifying operation while maintaining accuracy.
