Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If logging is suspended when state transition occurs, then logging resources are saved and unnecessary data is avoided, but logging continuity is broken and measurement precision deteriorates
Solution Approach 1:
The terminal performs preliminary actions by detecting state transition conditions before actual state transition occurs. When a state transition condition is detected, the terminal proactively logs the state transition information (including transition type, timestamp, and location) to ensure continuity of measurement data. This preliminary logging action prevents gaps in the measurement record that would otherwise occur during suspension and resumption cycles.
2Area of stationary object
If logging is resumed after suspension, then measurement coverage is improved, but logging results become discontinuous in time and measurement precision deteriorates
Solution Approach 1:
The terminal ensures continuity of useful action by maintaining logging operation across state transitions. Instead of suspending and resuming logging which creates temporal discontinuities, the terminal continuously logs measurement information including state transition events themselves. This approach preserves the temporal continuity of the measurement record while still capturing all relevant measurement data across different operational states.
Solution Approach 2:
The terminal implements feedback by logging state transition information that provides context about logging status changes. The logged state transition information includes timestamps and transition types that enable the network to understand the temporal relationships between measurements taken during different states. This feedback mechanism allows the network to reconstruct continuous coverage maps even when the terminal transitions between connected and idle states.
3Speed
If the terminal maintains logging configuration during suspension, then logging can be quickly resumed, but memory resources are consumed and device complexity increases
Solution Approach 1:
The terminal extracts and logs only the essential state transition information (transition type, timestamp, location) rather than maintaining complex logging configurations during suspension. This extracted minimal information approach reduces memory consumption and configuration management complexity while still enabling fast resumption of logging by providing the necessary context for continuous measurement recording.
