Engineering Contradiction Analysis
1Reliability
If constant transmission power is used to maintain reliable communication, then communication reliability is improved, but energy consumption increases and battery life decreases
Solution Approach 1:
The patent implements dynamic transmission power adjustment based on real-time distance calculations between radios. Instead of using constant transmission power, the system continuously determines the distance between transmitting and receiving radios using geo-location data, then adapts the transmission power level accordingly. This dynamic approach ensures reliable communication when needed while minimizing energy consumption when radios are close together.
Solution Approach 2:
The system changes the transmission power parameter based on calculated distance and attenuation. By computing the actual distance between radios using geo-location information and determining the required transmission power to overcome signal attenuation, the system optimizes the power parameter to balance communication reliability with energy efficiency.
2Area of stationary object
If constant transmission power is used to ensure coverage, then communication coverage is improved, but detectability by unwanted subscribers increases
Solution Approach 1:
The patent applies dynamic adjustment of transmission power based on actual distance requirements. By continuously monitoring the distance between transmitting and receiving radios and adapting the transmission power accordingly, the system maintains adequate communication coverage while minimizing the transmission range when full coverage is not needed, thereby reducing detectability by unwanted subscribers.
Solution Approach 2:
The system applies local quality by tailoring the transmission power to the specific local situation - the actual distance between the transmitting and receiving radios. Instead of using a uniform high power level across all conditions, the transmission power is locally optimized for each communication pair based on their specific separation distance, ensuring adequate coverage while minimizing unnecessary signal propagation.
3Reliability
If transmission power is increased to guarantee transmission to distant radio units, then communication reliability is improved, but battery life time decreases significantly
Solution Approach 1:
The patent implements dynamic transmission power control that adjusts power levels based on real-time distance measurements. By calculating the actual distance between radios using geo-location data and determining the minimum power required for reliable transmission at that distance, the system avoids unnecessary high-power transmission when radios are close, thereby preserving battery life while maintaining transmission reliability when needed.
Solution Approach 2:
The system applies partial action by using only the necessary transmission power required for reliable communication at the current distance, rather than consistently using maximum or excessive power. By calculating the precise power level needed based on distance and attenuation, the system avoids the excessive energy consumption that would result from always transmitting at high power, thus extending battery life while ensuring reliable transmission.
