Engineering Contradiction Analysis
1Reliability
If the amplitude or power of electromagnetic waves is increased to overcome electrical noise, then the signal strength becomes larger than background noise, but the electromagnetic interference and harmful electromagnetic exposure increase
Solution Approach 1:
The receiver measures the quality of the received electromagnetic wave and sends feedback information to the transmitter about the signal quality. The transmitter uses this feedback to dynamically adjust its transmission amplitude, increasing power only when necessary to maintain reliable communication while minimizing unnecessary electromagnetic emissions.
Solution Approach 2:
The transmission amplitude is made dynamic rather than static. The system continuously adapts the transmission power based on real-time channel conditions and receiver feedback, transitioning between different power levels to balance reliability requirements with electromagnetic pollution reduction.
2Reliability
If the amplitude or power of electromagnetic waves is increased to overcome electrical noise, then the signal strength becomes larger than background noise, but the energy consumption increases
Solution Approach 1:
The receiver provides feedback about signal quality to the transmitter, enabling the transmitter to adjust its power consumption dynamically. The transmitter consumes high energy only when the channel conditions require it for reliable communication, and consumes less energy when good signal conditions already exist.
Solution Approach 2:
The transmission amplitude parameter is changed dynamically based on channel conditions. By adjusting this parameter, the system optimizes the trade-off between achieving sufficient signal strength for reliable reception and minimizing the energy required for transmission.
3Object-generated harmful factors
If the amplitude or power of electromagnetic waves is decreased to reduce electromagnetic fields, then the harmful electromagnetic exposure is minimized, but the signal may become weaker than background noise
Solution Approach 1:
The receiver continuously monitors signal quality and provides feedback to the transmitter. When signal quality degrades below acceptable thresholds, the transmitter increases its amplitude to maintain reliability. This feedback loop ensures that amplitude is reduced to minimize exposure only when signal conditions permit, preventing reliability degradation.
Solution Approach 2:
The system dynamically transitions between low-amplitude and high-amplitude transmission modes based on real-time conditions. This dynamic adjustment allows the system to minimize electromagnetic exposure during favorable conditions while automatically increasing power when reliability requirements demand it.

AI summary
The process of an electronic device changing the amplitude or power of transmitted Electromagnetic Waves (EMW), as used with wireless devices, is in response to information that the electronic device that received the EMW sends to the electronic device that transmitted the EMW. The electronic device that receives EMWs determines the quality of the EMW received and conveys this information back to the electronic device that transmitted the EMW, so that the electronic device that transmits EMWs can adjust the amplitude or power of the EMW(s) in order to optimize the wireless communication between the electronic devices.
