Security Control Panel Power Output Prioritization for Backup Runtime
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security and fire systems face challenges in efficiently managing main and backup power, leading to potential system shutdowns when primary power is not restored before backup power expires.
Innovation Solution
A control panel with a controller that allows users to programmatically manage which devices receive main power only, backup power only, or both, ensuring critical components remain powered during main power outages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all devices are powered by backup power when main power fails, then system reliability is improved, but backup power duration is reduced
Solution Approach 1:
The system segments devices into critical and non-critical categories, allowing differential power management. Critical devices receive backup power while non-critical devices are powered down during main power failure, thus preserving backup power duration while maintaining essential system reliability.
Solution Approach 2:
Different power supply strategies are applied to different devices based on their criticality. Critical devices are assigned backup power capability while non-critical devices are assigned main power only, creating localized quality differences in power management that resolve the contradiction between system reliability and backup power duration.
2Reliability
If backup power is provided to all devices, then system operation is maintained, but energy consumption increases
Solution Approach 1:
The system divides devices into segments based on operational criticality. Only critical devices consume backup power during main power failure, while non-critical devices are powered down. This segmentation reduces overall energy consumption from backup power sources while maintaining essential system operations.
Solution Approach 2:
Instead of providing backup power to all devices (excessive action), the system provides backup power only to critical devices (partial action). This partial application of backup power is sufficient to maintain system operation while significantly reducing energy consumption from the backup power source.
3Duration of action of moving object
If backup power is limited to critical devices only, then backup power duration is extended, but system complexity increases
Solution Approach 1:
The system automatically determines device criticality and configures power supply relationships without requiring complex manual setup. The controller autonomously manages the switching between main and backup power sources based on pre-defined criticality parameters, reducing the perceived complexity for users while extending backup power duration.
Solution Approach 2:
The system performs preliminary configuration of power supply relationships during installation or setup phase. Criticality parameters and power routing are pre-determined, allowing the system to automatically execute the appropriate power management strategy during main power failure without requiring complex real-time decision-making, thus extending backup power duration while managing complexity.
4Adaptability or versatility
If power configuration is manually set for each device, then power management flexibility is improved, but ease of operation deteriorates
Solution Approach 1:
The system automatically determines and configures power supply relationships based on device criticality parameters. This self-service capability provides the flexibility of custom power configuration without requiring manual setup for each device, thereby maintaining adaptability while significantly improving ease of operation.
Solution Approach 2:
The controller implements a universal power management function that automatically handles multiple devices with different criticality levels. This multi-functional capability allows the system to adapt to various power management scenarios without requiring device-specific manual configuration, achieving both flexibility and ease of operation.

AI summary
A control panel includes a main power input, a backup power input, a plurality of power outputs for powering one or more external devices that are external to the control panel and a controller that is configured to receive a user assigned state for each of the power outputs, wherein the user assigned state includes a first state in which the corresponding power output provides main power when the main power is available and provides backup power when the main power is not available, and a second state in which the corresponding power output provides main power when the main power is available but does not provide backup power when the main power is not available. The controller is configured to control the one or more of the plurality of power outputs according to the corresponding user assigned state.
