Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If base stations are connected point-to-point through a core network, then reliable communication links are established, but hardware requirements excessively increase
Solution Approach 1:
The patent merges multiple point-to-point connections into a single point-to-multipoint connection structure. Instead of establishing separate dedicated links between each base station pair, a central base station consolidates multiple connections to peripheral base stations, reducing the number of required hardware interfaces and channels while maintaining communication reliability among all nodes.
Solution Approach 2:
The central base station in the point-to-multipoint configuration serves multiple functions simultaneously: it acts as a relay node, a coordination point, and a communication hub for multiple peripheral base stations. This multi-functionality eliminates the need for dedicated hardware for each specific connection type, reducing overall hardware requirements while ensuring reliable communication paths.
2Stability of the object's composition
If base stations use dedicated hardware for each connection, then communication stability is maintained, but the number of hardware items increases
Solution Approach 1:
Multiple connection interfaces that would traditionally require separate hardware items are merged into a single point-to-multipoint interface structure. The central base station uses one set of communication resources to maintain stable connections with multiple peripheral base stations simultaneously, reducing the quantity of hardware items from N separate connections to a consolidated multipoint interface.
Solution Approach 2:
The patent transitions from a two-dimensional point-to-point connection model to a three-dimensional point-to-multipoint star topology. This dimensional change allows a single central node to serve multiple connections in different spatial and logical dimensions, maintaining connection stability through structured topology while reducing hardware quantity through centralized resource management.
3Ease of operation
If base stations are connected through a core network, then network management is simplified, but infrastructure requirements increase
Solution Approach 1:
The patent extracts the network management function from the traditional core network infrastructure and relocates it to the point-to-multipoint base station interface. The central base station assumes management responsibilities including connection coordination, resource allocation, and communication routing, eliminating the need for extensive core network infrastructure while maintaining ease of operation through localized intelligent control.
Solution Approach 2:
The point-to-multipoint base station configuration enables self-service network management where the base stations themselves handle connection establishment, maintenance, and coordination without requiring external core network intervention. The central base station autonomously manages the multipoint connections, reducing infrastructure requirements while preserving operational simplicity through distributed intelligence.
