Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the burst reception time window duration is increased to capture more device reports for accurate location calculation, then measurement precision is improved, but processing time and system load increase
Solution Approach 1:
The patent implements dynamic adjustment of the burst reception time window duration based on device type, movement status, and location accuracy requirements. The system transitions from static to dynamic window sizing, allowing the receiver to adaptively extend or reduce the listening window according to real-time conditions, thereby optimizing the balance between capturing sufficient location data and minimizing processing time.
Solution Approach 2:
The system changes the parameter of burst reception time window duration based on multiple factors including device type (mobile vs. stationary), movement detection status, and required location accuracy. By adjusting this temporal parameter dynamically, the system achieves higher location precision when needed while reducing processing overhead during stable conditions.
2Reliability
If the burst reception time window duration is extended to capture complete device reports, then reliability of location data is improved, but productivity of the location system decreases
Solution Approach 1:
The system applies partial action by capturing only the necessary portion of device reports within the burst window rather than waiting for complete bursts. When location accuracy requirements are met with partial data, the system processes available information immediately, improving tracking speed while maintaining sufficient reliability through selective data capture based on device type and movement status.
Solution Approach 2:
The system uses feedback from device movement detection, location accuracy assessment, and burst completion status to dynamically adjust the reception window duration. This feedback mechanism allows the system to reliably capture necessary location data while avoiding unnecessary waiting for complete bursts, thereby maintaining high tracking productivity.
3Ease of operation
If the system processes all device reports with fixed time windows, then ease of operation is maintained, but adaptability to different device types and situations decreases
Solution Approach 1:
The system introduces dynamic adaptability by automatically adjusting burst reception window duration based on device type (mobile vs. stationary), movement detection status, and location accuracy requirements. This dynamic behavior enables the system to adapt to different scenarios without requiring manual configuration, maintaining ease of operation while significantly improving versatility.
Solution Approach 2:
The system changes operational parameters (burst window duration, processing priority) based on device characteristics and situational context. Mobile devices with movement detected receive extended monitoring windows, while stationary devices use standard windows, allowing the system to adapt efficiently to different device types and situations while remaining easy to operate.
4Device complexity
If the report processor uses fixed processing intervals, then device complexity is reduced, but loss of information occurs during high-movement situations
Solution Approach 1:
The system dynamically adjusts processing intervals based on detected device movement and location change magnitude. When significant movement is detected between bursts, the system extends the reception window or initiates additional processing cycles to capture updated location information, preventing information loss while maintaining relatively simple processing logic through movement-triggered adaptations.
Solution Approach 2:
The system uses feedback from comparing consecutive location estimates and detecting movement status to adjust processing behavior. When location changes exceed thresholds or movement is detected, the system adapts by extending reception windows or prioritizing processing, ensuring accurate location tracking during high-movement situations without requiring complex predetermined processing schedules.

AI summary
A location system for locating mobile wireless devices comprises at least one mobile wireless device (1a,1b) and at least one wireless receiver (3) configured to receive wireless transmissions from the mobile wireless device and to transmit bursts of device reports concerning the wireless transmissions to a report processor (11) of the system. The report processor is configured to receive the bursts of device reports from the wireless receiver, each burst of device reports to be received by the report processor during a respective burst reception time window. The report processor is also configured to vary the duration of the burst reception time window during use, in dependence at least upon: (i) a determination of a type of burst of device reports; and/or (ii) a measured duration of a previous burst of device reports.
