Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If more antenna elements are used for millimeter wave communications, then signal quality and reliability are improved, but power consumption and thermal overhead increase
Solution Approach 1:
The patent divides the antenna elements into multiple groups and configures different parameter sets for each group. The system can selectively activate specific antenna groups based on communication conditions, avoiding the need to power all antenna elements continuously. This segmentation allows maintaining communication reliability when needed while reducing power consumption by deactivating unused antenna groups.
Solution Approach 2:
The patent implements dynamic parameter configuration where transmission control parameters are adjusted based on the number of active antenna elements. The system can dynamically switch between different parameter sets corresponding to different antenna group configurations, enabling adaptive power management that balances reliability requirements with power consumption constraints in real-time.
2Reliability
If more antenna elements are used for millimeter wave communications, then signal quality and reliability are improved, but thermal overhead increases
Solution Approach 1:
By segmenting antenna elements into separate groups with independent parameter configurations, the system can activate only the necessary antenna groups for current communication needs. This reduces the number of actively operating antenna elements, thereby lowering thermal generation and overhead while maintaining sufficient signal quality through selective group activation.
Solution Approach 2:
The system can discard (deactivate) antenna groups that are not currently needed for communication, reducing thermal overhead. When communication conditions change or higher reliability is required, the system can recover (reactivate) the necessary antenna groups, dynamically managing thermal characteristics based on operational requirements.
3Productivity
If antenna parameter configuration is optimized for specific antenna groups, then communication efficiency is improved, but system complexity increases
Solution Approach 1:
The patent creates a universal parameter configuration framework where multiple parameter sets are defined, each corresponding to different antenna group configurations. This universal approach allows the same system to efficiently support various antenna groupings and communication scenarios without requiring separate dedicated configurations for each case, thereby improving communication efficiency while managing system complexity through a unified multi-functional parameter management structure.
