Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If UWB tags are configured to perform tag-to-tag ranging or tag-to-anchor ranging with uplink TDOA, then location service functionality is provided, but data transmission efficiency and localization accuracy are limited
Solution Approach 1:
The patent applies preliminary action by having the electronic device obtain assistant data (including location information of UWB anchors and configuration parameters) before performing UWB ranging operations. This pre-acquisition of necessary data enables the device to efficiently process UWB messages and perform localization without delays, thereby improving data transmission efficiency while maintaining reliable location service functionality.
2Reliability
If assistant data is transmitted through OOB device and application profile is registered and activated, then UWB messaging capability is enhanced, but device configuration complexity increases
Solution Approach 1:
The patent applies self-service by implementing an automated profile management system where the electronic device automatically obtains assistant data, registers the application profile, and activates UWB messaging capability without requiring manual configuration. The system performs self-configuration by obtaining necessary data through OOB channels and automatically setting up the UWB localization service, thereby enhancing messaging capability while minimizing the perceived complexity for users.
3Productivity
If part of localization information is transmitted through UWB message, then messaging efficiency is improved, but information completeness may be compromised
Solution Approach 1:
The patent applies segmentation by dividing localization information into two parts: assistant data (including anchor location information and configuration parameters) transmitted through efficient OOB channels, and partial localization information transmitted through UWB messages. This segmentation allows the system to maintain messaging efficiency by keeping UWB messages compact while ensuring information completeness by supplementing with assistant data obtained through other channels, thereby resolving the contradiction between messaging efficiency and information completeness.
