Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If devices are distributed across cellular and WLAN networks without coordination, then network coverage and user access are improved, but network congestion and service interruptions increase
Solution Approach 1:
The patent combines cellular and WLAN networks into a coordinated heterogeneous network system where devices from both networks work together as a unified group. Master devices from either network can organize slave devices to relay data, merging the capabilities of both networks to improve overall service reliability and reduce interruptions.
Solution Approach 2:
The patent introduces master devices as intermediary nodes that coordinate communication between slave devices and the external cellular network. These master devices act as mediators that manage data routing, select optimal transmission paths, and ensure reliable delivery even when direct connections are blocked, thereby improving service continuity.
2Productivity
If in-building devices attempt direct cellular connection, then external network access is achieved, but propagation blockages and signal loss occur
Solution Approach 1:
The patent enables devices within the building to self-organize into master-slave relationships, where slave devices use other devices in the same building as intermediaries to reach the cellular network. This self-service mechanism allows devices to overcome blockages by finding alternative paths through nearby devices without requiring external coordination.
Solution Approach 2:
The patent transforms the communication problem from a direct device-to-network connection into a multi-hop device-to-device-to-network path. By adding the dimension of intermediate relay devices, the system can bypass physical blockages and propagate signals through alternative routes around obstacles.
3Device complexity
If network parameters are statically configured, then system complexity is reduced, but communication efficiency and adaptability decrease
Solution Approach 1:
The patent implements dynamic master-slave relationships where devices can transition between roles based on changing network conditions. Master devices are selected based on real-time metrics such as link quality, signal strength, and available capacity, allowing the network to adapt efficiently to varying conditions without requiring complex static configuration for every scenario.
Solution Approach 2:
The patent changes key network parameters dynamically, including master device selection criteria, data routing paths, and transmission priorities. These parameters are adjusted based on measured link qualities, interference levels, and network congestion states, enabling efficient communication adaptation without overwhelming system complexity.
Data Source
AI summary
A communication system is described where multiple communication networks are simultaneously accessible from a plurality of fixed and/or mobile communication devices. A Master and Slave hierarchy is implemented among the communication devices to improve communication properties on one or multiple networks. Slave devices are configured to access cellular networks through routing of data with a master device within a sub-network.
