Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If MIMO and beamforming are combined to extend range and enhance throughput, then communication performance is improved, but system complexity increases
Solution Approach 1:
The patent combines MIMO and beamforming technologies into a unified system where multiple antenna arrays with beamformers work together with MIMO transceivers. This merging allows the system to achieve both range extension and throughput enhancement while managing complexity through integrated architecture rather than separate systems
Solution Approach 2:
The antenna arrays are designed to perform multiple functions simultaneously - they serve as both MIMO antennas for spatial diversity and beamforming elements for directional communication. This multi-functionality reduces the need for separate dedicated components, thereby managing system complexity while achieving improved communication performance
2Length of moving object
If multiple antenna arrays with beamformers are used, then range extension is achieved, but cost increases
Solution Approach 1:
The system divides the communication function across multiple antenna arrays, each with its own beamformer. This segmentation allows for modular implementation where arrays can be added or configured based on specific range requirements, avoiding the need for a single complex high-cost system and enabling scalable deployment
3Adaptability or versatility
If multiple MIMO transceivers are integrated with antenna arrays, then simultaneous MIMO and beamforming capabilities are enabled, but device complexity increases
Solution Approach 1:
The patent integrates MIMO transceivers directly with the antenna arrays that contain beamformers, creating a unified transceiver system. This merging eliminates the need for separate MIMO and beamforming hardware blocks, reducing overall device complexity while maintaining full functionality for simultaneous MIMO and beamforming operations
