Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If fixed transmission power is used during wireless communication, then communication coverage and reliability are maintained, but power consumption increases and energy efficiency deteriorates
Solution Approach 1:
The patent implements dynamic transmission power adjustment by continuously monitoring application bandwidth requirements and modifying transmission power levels in real-time. The controller dynamically adapts the communication module's transmission power based on current application needs, transitioning from fixed to variable power operation to optimize energy efficiency while maintaining communication quality.
Solution Approach 2:
The patent changes the transmission power parameter based on application bandwidth requirements. By calculating the required bandwidth for executing applications and mapping it to appropriate power levels, the system adjusts the transmission power parameter dynamically, allowing lower power consumption when high bandwidth is not needed while maintaining sufficient power when applications require higher data rates.
2Reliability
If high transmission power is used to ensure communication quality, then data transmission reliability is improved, but energy waste increases
Solution Approach 1:
The patent applies partial action by adjusting transmission power to match the minimum necessary level for current application requirements. Instead of consistently using high transmission power, the system uses just enough power to satisfy the bandwidth needs of executing applications, avoiding excessive energy consumption when full power is not required.
Solution Approach 2:
The patent implements a feedback mechanism where the controller continuously monitors application bandwidth requirements and uses this information to adjust transmission power levels. This closed-loop control ensures that transmission power is optimized based on actual communication needs, preventing energy waste while maintaining data transmission performance.
3Use of energy by moving object
If transmission power is reduced to save energy, then power consumption decreases, but communication range and quality may deteriorate
Solution Approach 1:
The patent dynamically adjusts transmission power based on real-time application bandwidth requirements rather than using a fixed low power level. This dynamic approach ensures that when applications require higher bandwidth, transmission power is increased to maintain communication quality and effective range, while allowing power reduction when applications have lower bandwidth needs.
Solution Approach 2:
The patent changes transmission power parameters in response to application bandwidth requirements. By calculating required bandwidth and mapping it to appropriate power levels, the system ensures that transmission range and quality are maintained when needed while reducing power consumption when high performance is not required.
