Engineering Contradiction Analysis
1Ease of operation
If wireless communication is set based on standard measurement conditions, then communication setup is simple, but signal attenuation occurs when obstacles are present
Solution Approach 1:
The system changes the transmission signal parameters (power level, frequency) based on the identified obstacle material properties. The processor adjusts communication parameters dynamically according to the dielectric constant and signal attenuation characteristics of detected materials like concrete, brick, or glass walls.
Solution Approach 2:
The system implements feedback by detecting obstacle materials using sensors or images, processing this information to determine appropriate transmission parameters, and adjusting the wireless communication settings accordingly. This closed-loop approach ensures reliable communication despite varying environmental conditions.
2Reliability
If transmission signal strength is increased to overcome obstacle attenuation, then communication reliability improves, but energy consumption increases
Solution Approach 1:
The system dynamically adjusts transmission signal parameters based on the identified obstacle characteristics. Instead of using maximum power always, the processor selects appropriate power levels and frequency parameters matched to the specific material and distance conditions, optimizing the balance between reliability and energy efficiency.
Solution Approach 2:
The transmission parameters are made dynamic rather than static. The system continuously monitors the environment, identifies obstacle materials, and adjusts transmission power and parameters in real-time based on current conditions, allowing the system to use minimal necessary energy while maintaining reliability.
