Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the prediction period of orbit information is increased to improve usability, then the reliability of positioning is improved, but the data amount increases causing longer acquisition time and higher power consumption
Solution Approach 1:
The system dynamically adjusts the prediction period of orbit information based on the operational state of the positioning apparatus. When power capacity is restricted or immediate positioning is required, the system shortens the prediction period to reduce data amount and power consumption. When power is充足 and usability is prioritized, the system extends the prediction period to improve reliability. This dynamic adaptation resolves the contradiction by making the prediction period flexible rather than fixed.
Solution Approach 2:
The system changes the parameter of prediction period based on power capacity and operational requirements. By adjusting this key parameter dynamically, the system optimizes the balance between data amount, acquisition time, power consumption, and usability. The parameter change allows the same system to serve different operational scenarios without compromising core functionality.
2Reliability
If the prediction period of orbit information is increased to improve usability, then the reliability of positioning is improved, but the acquisition time increases reducing positioning speed
Solution Approach 1:
The system dynamically adjusts the prediction period based on operational state to balance usability and positioning speed. When immediate positioning is required or communication conditions are constrained, the system shortens the prediction period to accelerate acquisition. When time is not critical and usability is prioritized, the system extends the prediction period. This dynamic adjustment resolves the contradiction between reliability and speed.
3Reliability
If the prediction period of orbit information is increased to improve usability, then the reliability of positioning is improved, but the positioning process duration is reduced under power constraints
Solution Approach 1:
The system dynamically adapts the prediction period to the power capacity and operational requirements. Under power constraints, the system shortens the prediction period to extend the positioning process duration and improve responsiveness. When power is充足, the system extends the prediction period to enhance usability. This dynamic adaptation resolves the contradiction between reliability and operational duration.
