Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional 5G towers are deployed to provide wide area coverage and high throughput, then network performance is improved, but visual impact and aesthetic concerns worsen
Solution Approach 1:
The patent segments the 5G infrastructure into small cell units that can be distributed across multiple ordinary places (light poles, building tops, street lights) rather than using single large towers. This segmentation allows network performance to be maintained through distributed coverage while reducing the visual impact of any individual infrastructure element.
Solution Approach 2:
The patent transitions from vertical deployment (tall towers) to horizontal deployment (distributed small cells across multiple locations). By changing the dimensional approach from height-based coverage to area-based distributed coverage, the system maintains network performance while eliminating the need for visually prominent tall structures.
2Speed
If small cell towers are installed frequently to support superfast speeds with direct line of sight, then throughput is improved, but device complexity and deployment difficulty worsen
Solution Approach 1:
The patent designs small cell units with steerable antennas and liquid lens capabilities that can adapt to different deployment environments and user requirements. This multi-functionality allows a single small cell design to serve multiple purposes across diverse locations, reducing overall system complexity despite the increased number of units required.
Solution Approach 2:
The patent incorporates steerable antennas and adjustable liquid lenses in small cells that can dynamically change their beam direction and focus. This dynamic capability allows each small cell to optimize its coverage area and maintain direct line of sight connections, reducing the need for precise static positioning and simplifying deployment.
3Productivity
If massive MIMO with multiple antennas is used to increase channel transmission capacity, then data rate is improved, but channel estimation accuracy worsens due to pilot contamination
Solution Approach 1:
The patent introduces liquid lenses as intermediary optical elements between the antennas and the communication channel. These liquid lenses can dynamically focus and steer beams, enabling better spatial separation of signals from different transmitters. This intermediary capability helps reduce pilot contamination by improving the precision of beam direction control and signal isolation.
Solution Approach 2:
The patent utilizes the ability to change the curvature and refractive index parameters of liquid lenses to dynamically adjust beam focusing and direction. By changing these optical parameters in real-time, the system can optimize channel estimation accuracy while maintaining high data rates through massive MIMO operations.
