Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If UWB ranging is used to identify location, then location identification accuracy is improved, but device compatibility deteriorates because non-UWB devices cannot be identified
Solution Approach 1:
The patent introduces UWB devices as intermediary elements that perform ranging measurements and share location information with the non-UWB device through other communication channels. This mediator approach allows the system to achieve accurate location identification using UWB technology while maintaining compatibility with devices that do not support UWB, as the non-UWB device can still be identified and controlled through information sharing from the UWB devices.
2Measurement precision
If multiple UWB devices are used for ranging, then location identification capability is improved, but system complexity increases
Solution Approach 1:
The patent divides the system into distinct functional segments: UWB devices that perform ranging measurements and non-UWB devices that are identified through shared location information. This segmentation allows the complex UWB ranging functionality to be isolated to specific devices, while other devices can remain simpler, reducing overall system complexity while maintaining location identification capability.
