Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If detailed position information is exchanged frequently, then positional accuracy and service effectiveness are improved, but wireless resource consumption increases
Solution Approach 1:
The patent applies dynamics by making the position reporting parameters adjustable and adaptive rather than fixed. The system dynamically modifies reporting intervals, threshold distances, and information detail levels based on current service requirements, device state, and network conditions. This allows the system to optimize between positional accuracy and resource consumption in real-time, reporting more frequently and with greater detail when accuracy is critical, and reducing reporting when resources are constrained.
Solution Approach 2:
The patent implements parameter changes by allowing dynamic modification of position reporting parameters including reporting intervals, distance thresholds, velocity thresholds, and information detail levels. These parameters can be adjusted based on service type, device battery status, network load, and positional accuracy requirements. By changing these parameters adaptively, the system resolves the contradiction between maintaining high positional accuracy and minimizing wireless resource consumption.
2Reliability
If position reporting is performed continuously, then tracking accuracy is improved, but system capacity is exceeded
Solution Approach 1:
The patent applies partial action by implementing selective position reporting where the mobile device transmits position information only when specific conditions are met, such as when movement exceeds a threshold distance, when a specific time interval has elapsed, or when entering/exiting predefined geographic areas. This partial reporting approach maintains sufficient tracking accuracy for the service requirements while significantly reducing the overall system capacity consumption compared to continuous reporting of all position fixes.
Solution Approach 2:
The patent implements periodic action through time-based reporting intervals where position information is transmitted at regular intervals rather than continuously. The reporting interval can be dynamically adjusted based on service requirements and network conditions. This periodic approach ensures tracking accuracy is maintained at acceptable levels while preventing system capacity from being exceeded by overly frequent transmissions.
3Loss of energy
If minimal position information is exchanged, then wireless resources are conserved, but service relevance is reduced
Solution Approach 1:
The patent applies local quality by allowing different levels of position information detail to be transmitted based on the specific service requirements and current context. Rather than uniformly minimizing all information, the system selectively includes or excludes certain position data elements such as precise coordinates, altitude, velocity, course, or timestamp based on what is locally relevant to each service. This ensures wireless resources are conserved while maintaining service relevance by including only the necessary information quality for each specific application.
Solution Approach 2:
The patent implements parameter changes by dynamically adjusting the detail level and content of position information transmitted. The system can modify parameters such as coordinate precision, inclusion of auxiliary data (velocity, course, altitude), and reporting frequency based on service requirements and network conditions. This allows the system to conserve wireless resources by minimizing information when possible, while ensuring service relevance is maintained by increasing information detail when required by the specific application.

AI summary
A dynamic position reporting and/or logging scheme is described herein. Position reporting and/or logging for a mobile device may be dynamically determined based on one or more reporting and/or logging constraints. The constraints may be based on time, distance, events, operating parameters, operating conditions, or some combination thereof. The constraints that dynamically trigger position reporting may be the same as, overlap, or be distinct from the constraints used to trigger position logging. The reporting and logging constraints can be selected to provide a more accurate indication of a track or route traveled by the mobile device.
