Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If high-power wireless transmission modules are used for Remote ID broadcasting, then transmission distance is extended and signal-to-noise ratio is improved, but energy consumption increases and battery life is reduced
Solution Approach 1:
The patent changes the power parameter of the wireless transmission module dynamically based on the type of data being transmitted. For Remote ID broadcasting, it uses low-power mode with reduced transmission power, while for control commands and image transmission, it switches to high-power mode. This parameter adjustment resolves the contradiction by adapting power consumption to actual transmission needs.
Solution Approach 2:
The patent implements dynamic switching between different power modes of the wireless transmission module. The system dynamically adjusts transmission power based on the data type being transmitted, transitioning from static high-power operation to dynamic power management. This enables the system to maintain reliable communication when needed while conserving energy during Routine Remote ID broadcasting.
2Length of moving object
If high-power wireless transmission modules are used for all transmissions, then transmission distance is extended, but energy consumption increases
Solution Approach 1:
The patent adjusts the transmission power parameter based on the specific transmission task. For Remote ID broadcasting where long distance is not critical, it uses low-power mode. For control commands and image transmission requiring extended distance, it switches to high-power mode. This selective parameter adjustment optimizes the balance between transmission distance and energy consumption.
Solution Approach 2:
The patent applies partial power transmission instead of always using maximum power. For Remote ID broadcasting, it uses just enough power to achieve adequate coverage without excessive transmission strength. This partial action approach reduces energy consumption while maintaining sufficient transmission distance for the specific application.
