Innovation Solution
A monitored voltage inverter is integrated into the security system's power supply, converting DC power from a back-up source to AC power for network hardware devices, ensuring continuous operation and monitoring of network components during AC power interruptions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If individual battery back-up is provided for each network component device, then the network component device remains operable during AC power interruption, but the system becomes costly, cumbersome, and difficult to maintain
Solution Approach 1:
The patent combines multiple network component devices into a single network enclosure that shares a common battery back-up power supply. Instead of providing separate battery backups for each device (switches, routers, modems), the invention merges their power requirements into one centralized power system with a single battery unit, thereby maintaining reliability while reducing complexity and maintenance burden
Solution Approach 2:
The battery back-up power supply is designed to serve multiple network component devices simultaneously through a single power source. The universal power supply can accommodate various types of network equipment (switches, routers, modems) within the enclosure, providing multi-functional support without requiring device-specific backup systems
2Reliability
If individual battery back-up is provided for each network component device, then continuous operation is achieved, but the bulk added to each device makes placement unwieldy
Solution Approach 1:
The invention merges the power supply function into a centralized enclosure that houses multiple network devices. Instead of adding bulky battery units to each individual device, the combined enclosure shares a single battery back-up system, significantly reducing the weight and bulk of each individual component while maintaining continuous operation capability
3Reliability
If individual battery back-up is provided for each network component device, then power continuity is ensured, but the cost of checking and maintaining each battery becomes prohibitive
Solution Approach 1:
The patent merges multiple battery maintenance requirements into a single maintenance task. By providing one common battery back-up for the entire network enclosure rather than separate batteries for each device, the system reduces maintenance costs and simplifies checking procedures, making the system more economically viable while ensuring power continuity
4Ease of manufacture
If traditional AC-powered network components are used, then low-cost commercially available components can be utilized, but the system becomes inoperable during AC power outages
Solution Approach 1:
The invention introduces a voltage inverter as an intermediary device that enables low-cost AC-powered network components to operate during DC battery back-up conditions. The voltage inverter converts DC battery power to AC power, allowing standard commercial network equipment to function without requiring expensive AC-powered infrastructure or specialized DC-adapted components
Solution Approach 2:
The system dynamically changes the power supply parameter from AC to DC during outages by activating the battery back-up and voltage inverter. This parameter change enables the network components to continue operating on alternative power (DC converted to AC) when the original AC power source fails, maintaining reliability without increasing component cost
