Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If conventional beamforming is employed in cellular systems, then communication range is extended, but bandwidth is limited and throughput reaches theoretical limits
Solution Approach 1:
The patent combines beamforming technology with MIMO (Multiple-Input Multiple-Output) systems, merging the directional signal focusing capability of beamforming with the spatial multiplexing capability of MIMO. This integration allows the system to achieve both extended transmission range through beamforming and high throughput through multiple spatial streams, resolving the contradiction between range and bandwidth.
Solution Approach 2:
The patent introduces spatial dimensionality by utilizing multiple antennas for simultaneous transmission of multiple data streams (MIMO), adding a new dimension to the communication system. This dimensional expansion allows the system to overcome the bandwidth limitation of conventional single-stream beamforming while maintaining extended range through directional transmission.
2Adaptability or versatility
If base stations perform beamforming to communicate with numerous vehicles, then communication coverage is improved, but system complexity and database size increase substantially
Solution Approach 1:
The patent segments the beamforming function by implementing it at both the base station and the mobile terminal (vehicle). This segmentation distributes the computational burden and tracking requirements, reducing the complexity at any single point while maintaining comprehensive communication coverage through coordinated beamforming between multiple entities.
3Productivity
If wireless LAN is used indoor, then bandwidth is substantially wide, but transmission range is relatively short
Solution Approach 1:
The patent merges the high bandwidth capability of wireless LAN with the extended range capability of beamforming technology. By integrating these two technologies, the system achieves both wide bandwidth for high throughput and extended transmission range through directional signal focusing, resolving the contradiction between bandwidth and range.
