Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed antenna configuration is used in a moving object, then the device complexity is reduced and ease of operation is improved, but the reliability of communication deteriorates when the object moves or is far from a base station
Solution Approach 1:
The patent implements dynamic antenna configuration where the number of antennas for each function (sensing, data, control) is adjusted in real-time based on environmental conditions such as signal strength and moving speed. This dynamic adaptation resolves the contradiction by maintaining high communication reliability through optimized antenna allocation while using automated algorithms to minimize the perceived complexity for operators.
Solution Approach 2:
The system continuously monitors environmental information including received signal strength and moving speed, then uses this feedback to automatically adjust antenna configuration. This closed-loop feedback mechanism ensures communication quality is maintained adaptively without requiring complex manual intervention, thus resolving the reliability-complexity contradiction.
2Adaptability or versatility
If multiple antennas are established with fixed functions, then the device complexity is reduced, but the adaptability to different environmental conditions deteriorates
Solution Approach 1:
The patent enables dynamic reconfiguration of antenna functions based on environmental conditions. The antenna use determination unit adjusts the number of sensing antennas, data antennas, and control antennas according to signal strength and moving speed, providing high adaptability while using automated decision-making to manage system complexity.
Solution Approach 2:
The communication antennas are designed to be multi-functional, capable of serving as sensing antennas, data antennas, or control antennas depending on environmental requirements. This universal design allows a single antenna system to adapt to various communication scenarios without requiring separate dedicated antennas for each function, thus improving adaptability while controlling overall system complexity.
3Measurement precision
If the number of sensing antennas is increased to improve frequency band detection, then the measurement precision is improved, but the use of energy by the moving object increases
Solution Approach 1:
The patent implements partial action by dynamically adjusting the number of sensing antennas based on actual environmental needs. When signal strength is sufficient or moving speed is low, fewer sensing antennas are activated. When signal strength is weak or moving speed is high, more sensing antennas are activated to improve detection precision. This partial activation strategy achieves adequate measurement precision while minimizing energy consumption.
Solution Approach 2:
The system changes the operational parameters of the antenna system by adjusting the number of active sensing antennas based on environmental conditions such as signal strength and moving speed. This parameter adjustment allows the system to optimize the balance between detection precision and energy consumption dynamically, rather than maintaining a fixed high-energy configuration.
4Productivity
If the number of data antennas is increased to achieve higher data transmission rates, then the productivity is improved, but the device complexity increases
Solution Approach 1:
The patent implements dynamic adjustment of data antenna数量 based on moving speed and signal strength. When the moving object travels at high speed or experiences weak signals, more data antennas are activated to maintain high data transmission rates. When conditions are favorable, fewer data antennas are sufficient. This dynamic approach achieves high productivity when needed while avoiding the constant complexity of maintaining a maximum antenna configuration.
