Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If UWB-based positioning solutions are integrated into industrial monitoring systems to achieve high positioning accuracy, then positioning precision is improved, but channel capacity limitations cause measurement collisions and reduced measurement success rate
Solution Approach 1:
The system dynamically adjusts positioning configurations based on real-time channel conditions and measurement requirements. Configuration parameters such as measurement intervals, ranging modes, and resource allocation are adaptively modified to optimize both positioning accuracy and measurement success rate under varying industrial environment conditions.
Solution Approach 2:
The patent modifies key parameters including measurement timing, resource allocation, and ranging protocol selection to balance positioning precision with channel capacity constraints. By changing these parameters dynamically, the system resolves the contradiction between achieving high measurement precision and maintaining reliable measurement success rates.
2Speed
If simultaneous motion-based triggering is used for multiple tags to enable real-time tracking, then tracking responsiveness is improved, but channel capacity is exceeded causing measurement collisions
Solution Approach 1:
The system segments the simultaneous measurement requests from multiple tags into time-multiplexed or resource-separated measurement opportunities. By dividing the measurement process into distinct time slots or resource allocations, the system maintains responsive tracking while preventing channel capacity overflow and measurement collisions.
Solution Approach 2:
The patent implements periodic measurement cycles with controlled triggering intervals for multiple tags. Instead of allowing completely simultaneous motion-based triggering, the system uses periodic measurement opportunities with coordinated timing to reduce collision probability while maintaining acceptable tracking responsiveness.
3Reliability
If repeated measurements are performed for constant object positions to ensure positioning accuracy, then measurement reliability is improved, but energy consumption and channel usage increase unnecessarily
Solution Approach 1:
The system employs self-service mechanisms where the positioning system automatically determines when repeated measurements are necessary based on detected changes in object position or channel conditions. Tags and anchor nodes autonomously adjust their measurement activity, performing repeated measurements only when position changes are detected or reliability thresholds are not met, thereby avoiding unnecessary energy consumption.
Solution Approach 2:
The patent implements feedback mechanisms that monitor positioning results and channel conditions to dynamically control measurement frequency. When positioning reliability is sufficient and objects are stationary, the feedback loop reduces measurement frequency to conserve energy. When position changes are detected or reliability degrades, the system automatically increases measurement frequency to maintain accuracy.

Implementation Method 1
measurements are performed between the tag devices and the anchor nodes using radio technology (e.g., Bluetooth, WiFi, Ultra-Wideband (UWB) technology, etc.) to determine the precise tag positions
Implementation Method 2
various methods that use distance measurements between anchors and tag devices may be employed to calculate the tag positions, each having certain benefits and drawbacks. Widely used ranging protocols include Two Way Ranging (TWR) and Time Difference Of Arrival (TDOA)
