Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple WCMs connect to the same base station through the same frequency band, then connectivity is established, but data transmission rate is reduced due to limited bandwidth
Solution Approach 1:
The patent segments the WCMs into different groups, where each group connects to a different base station. This segmentation allows multiple WCMs to utilize different frequency bands simultaneously, thereby increasing overall data transmission rate while maintaining connectivity for all WCMs.
Solution Approach 2:
The patent introduces a new dimension of base station selection by utilizing rotational and tiltable antenna elements. This mechanical dimensionality change enables the antenna to physically orient toward different base stations, allowing WCMs to access different frequency bands and expand the system's bandwidth utilization beyond what would be available with fixed antennas.
2Productivity
If multiple WCMs connect to different base stations, then data transmission rate is improved, but device complexity increases due to rotatable and tiltable antenna elements
Solution Approach 1:
The patent employs dynamic antenna elements that can rotate and tilt to change their orientation in space. This dynamic capability allows the same antenna structure to serve multiple base stations located in different directions, achieving the benefit of connecting to multiple base stations without requiring multiple separate antenna systems.
Solution Approach 2:
The rotatable and tiltable antenna element serves multiple functions: it can orient toward different base stations, access different frequency bands, and maintain connectivity under varying geographical conditions. This multi-functionality reduces the need for separate dedicated antennas for each base station, thereby managing device complexity more effectively.
3Adaptability or versatility
If antenna directions are changed based on geographical area, then bandwidth utilization is optimized, but control complexity increases
Solution Approach 1:
The patent incorporates a control system that receives feedback regarding the network node's geographical area and automatically adjusts the antenna orientation accordingly. This feedback mechanism enables the system to adapt to changing environments and optimize bandwidth utilization by connecting to the most suitable base stations without requiring manual intervention.
Solution Approach 2:
The control system automatically determines the optimal antenna orientation based on geographical information and base station characteristics, enabling the system to self-adjust and optimize its connections. This self-service capability reduces the need for external control and simplifies the overall system operation despite the underlying complexity of the antenna mechanism.

AI summary
Methods and systems for improving connectivity between a network node and a base station during data communication over a cellular network are described. The network node comprises a first plurality of WCMs. The method includes identifying, by the network node, a first base station connected to a second plurality of WCMs. The second plurality of WCMs include all or part of the first plurality of WCMs. After that, a WCM is selected from the second plurality of WCMs to maintain a connection with the first base station. The rest of the second plurality of WCMs are disconnected from the first base station. The disconnected WCMs are reconnected in a manner so that each of the second plurality of WCMs becomes connected to a different base station or to the same base station over different frequency bands.
