Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless communications are used for premises monitoring systems, then installation flexibility is improved, but communication reliability deteriorates during outages
Solution Approach 1:
The patent introduces a cellular converter as an intermediary device that translates between cellular network communications and local area network (LAN) communications. This mediator enables premises monitoring systems to communicate reliably through cellular networks when traditional internet connections are unavailable, without requiring changes to existing monitoring equipment. The converter acts as a bridge that maintains communication reliability while preserving installation flexibility.
2Quantity of substance
If bandwidth is allocated for multiple devices, then network capacity is improved, but bandwidth availability for critical devices deteriorates
Solution Approach 1:
The patent implements local quality by assigning different bandwidth priorities to different devices based on their criticality. The cellular converter monitors network conditions and dynamically allocates bandwidth, ensuring that critical premises monitoring devices receive minimum guaranteed bandwidth while allowing non-critical devices to use available capacity. This creates localized quality differences in bandwidth allocation across the network.
Solution Approach 2:
The system dynamically adjusts bandwidth allocation based on real-time network conditions and device priorities. The cellular converter continuously monitors bandwidth usage and automatically reconfigures network resources to ensure critical devices maintain reliable communication even when total network capacity is limited. This dynamic adaptation resolves the contradiction between maximizing overall network capacity and guaranteeing bandwidth for critical devices.
3Reliability
If cellular communication is used during outages, then communication continuity is improved, but data transmission efficiency deteriorates
Solution Approach 1:
The patent applies partial action by selectively transmitting only essential monitoring data through the cellular network during outages, rather than attempting to maintain full network functionality. The cellular converter prioritizes critical alarm and status information for transmission, accepting reduced overall data transmission efficiency in exchange for maintaining communication continuity for essential functions.
