Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wireless communication sessions are actively maintained, then communication reliability is improved, but battery life deteriorates
Solution Approach 1:
The system dynamically adjusts wireless interface states based on real-time battery charge levels. When battery charge is sufficient, the interface maintains active communication sessions for reliable connectivity. When battery charge drops below thresholds, the system transitions to power-saving states, selectively terminating sessions or reducing activity to extend battery life while maintaining essential communication capabilities.
Solution Approach 2:
The system changes operational parameters of wireless interfaces based on battery charge levels. It monitors battery charge and adjusts parameters such as transmission power, session maintenance frequency, and interface activity levels to optimize the balance between communication reliability and power consumption.
2Adaptability or versatility
If multiple wireless interfaces are actively communicating, then communication versatility is improved, but power consumption increases
Solution Approach 1:
The system applies partial action by selectively activating only the necessary wireless interfaces based on current communication needs and battery charge levels. Instead of keeping all interfaces actively communicating, it maintains only those required for current tasks, reducing overall power consumption while preserving essential communication versatility.
Solution Approach 2:
The wireless interface controller automatically monitors battery charge levels and autonomously manages interface activation and termination without user intervention. This self-service mechanism dynamically allocates power resources among multiple interfaces, ensuring versatile communication capability when battery is charged while automatically reducing activity to conserve power when battery charge is low.
3Use of energy by moving object
If transmission power is reduced to save energy, then power consumption is improved, but signal strength deteriorates
Solution Approach 1:
The system dynamically adjusts transmission power based on real-time battery charge levels and communication conditions. When battery charge is high, transmission power is maintained at higher levels for strong signal strength. When battery charge drops, the system reduces transmission power to conserve energy, accepting reduced signal strength as a necessary trade-off to extend operational battery life.
