Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional-sized antennas are used, then the antenna can handle standard transmission requirements, but the base station density remains low and data transmission capacity is limited
Solution Approach 1:
The patent changes the physical parameters of the antenna by reducing its size to be suitable for high frequency and short wavelength transmission bands. This parameter change enables more antennas to be installed in the same space, increasing base station density and data transmission capacity simultaneously
Solution Approach 2:
The patent divides the traditional large antenna system into multiple miniature antennas that can be independently installed in various locations such as vehicles, traffic poles, and trash cans. This segmentation allows the system to achieve higher density by distributing multiple small antennas throughout the service area
2Speed
If more antennas are installed to increase MIMO capabilities, then data transmission speed improves, but the installation space requirement increases
Solution Approach 1:
The patent changes the size parameter of the antennas to miniature dimensions that are suitable for high frequency and short wavelength transmission. This enables multiple antennas to be installed in limited spaces such as vehicles and traffic poles, achieving MIMO capabilities without requiring large installation areas
Solution Approach 2:
The patent moves antenna installation from traditional fixed terrestrial locations to multiple dimensions including vehicles, traffic poles, and mobile devices. This spatial dimensionality change allows more antennas to be deployed in the same physical footprint, increasing MIMO capabilities without proportionally increasing installation space
