Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a fixed signal transmitting manner is used for wireless communication, then the device structure is simple, but the wireless communication performance deteriorates under varying circumstances
Solution Approach 1:
The patent implements dynamic signal transmitting manners that automatically adapt to varying communication environments. The system switches between different transmission modes (e.g., transmission intervals, packet structures, power levels) based on real-time channel conditions, ensuring optimal communication performance without requiring complex manual configuration.
Solution Approach 2:
The patent changes multiple signal transmission parameters including transmission intervals, packet lengths, and power levels based on communication distance and environmental conditions. By dynamically adjusting these parameters, the system maintains reliable wireless communication while avoiding excessive complexity in the overall device structure.
2Reliability
If the signal transmitting manner is modified frequently to adapt to circumstances, then the wireless communication performance is maintained, but the control complexity increases
Solution Approach 1:
The patent employs feedback mechanisms where the wireless communication device monitors transmission success rates, signal quality, and communication distance. Based on this feedback, the controller automatically adjusts signal transmitting parameters without requiring complex external intervention, thereby maintaining performance while limiting control complexity to essential monitoring and adjustment functions.
3Adaptability or versatility
If multiple wireless communicators with different communication capacities are used, then the adaptability to various circumstances is improved, but the device complexity increases
Solution Approach 1:
The patent designs the wireless communication device with multi-functional capabilities that can operate in multiple transmission modes using a single integrated wireless communicator unit. The device can function as both a transmitter and receiver, support different communication protocols, and adapt to various transmission distances, thereby achieving versatility without proportionally increasing device complexity.
