Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If a zero-power consumption terminal uses backscatter mode to transmit signals, then power consumption is reduced, but transmission reliability may deteriorate
Solution Approach 1:
The terminal dynamically switches between backscatter mode and active transmission mode based on real-time assessment of transmission conditions. The system evaluates factors such as signal strength, interference level, and channel quality to determine the optimal transmission mode, thereby adapting to changing environmental conditions and resolving the contradiction between power saving and transmission reliability.
Solution Approach 2:
The system changes the transmission parameter (mode selection) based on the assessment results. When the assessed transmission conditions meet predefined thresholds, the terminal switches from backscatter mode to active transmission mode, using parameter change to balance power consumption and transmission reliability under different operational conditions.
2Reliability
If a terminal uses active transmission mode, then transmission reliability is improved, but power consumption increases
Solution Approach 1:
The terminal dynamically switches between backscatter mode and active transmission mode based on real-time assessment of transmission conditions. The system evaluates factors such as signal strength, interference level, and channel quality to determine the optimal transmission mode, thereby adapting to changing environmental conditions and resolving the contradiction between power saving and transmission reliability.
Solution Approach 2:
The terminal autonomously assesses its own transmission conditions and makes independent decisions on mode selection without external control. The self-service mechanism allows the terminal to monitor its power status, signal quality, and transmission needs, then automatically select the most appropriate mode to balance reliability and power consumption.
3Use of energy by moving object
If the terminal frequently switches between transmission modes, then power saving is optimized, but system complexity increases
Solution Approach 1:
The system performs preliminary assessment of transmission conditions before mode switching occurs. By evaluating signal strength, interference levels, and channel quality in advance, the terminal can make informed decisions about mode selection, reducing unnecessary switching and simplifying the control logic while still achieving optimal power saving.
Solution Approach 2:
The terminal uses feedback mechanisms to continuously monitor transmission quality and power consumption. Based on this feedback, the system adjusts its mode selection strategy, learning from past performance to make more accurate predictions about optimal switching timing, thereby reducing complexity through intelligent control.
