Electric Meter Adaptor for Live Backup Power Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for connecting a backup power source to a building require termination of utility power, necessitating the presence of power line technicians and electricians, followed by inspections, which is time-consuming and inefficient.
Innovation Solution
An electric meter adaptor that allows the connection of a backup power source between an electric meter block and an electric meter without terminating electrical power from the utility source, using a housing with specific blade configurations to facilitate the connection of the backup power source, transfer switch, and meter, enabling seamless integration without disrupting the utility power supply.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the existing method of connecting backup power source is used (requiring power termination), then safety is ensured, but installation time and complexity increase significantly
Solution Approach 1:
The patent introduces a transfer switch as an intermediary device between the utility power source and the building's electrical system. This transfer switch enables safe switching between utility power and backup power source without requiring complete power termination, thereby maintaining safety while reducing installation time and complexity
Solution Approach 2:
The patent implements preliminary configuration of the transfer switch and backup power source connection before utility power termination is required. The transfer switch is pre-installed and configured to handle the switching operation, so that when backup power connection is needed, the actual power switching can be done quickly without complex on-site wiring work
2Reliability
If power line technicians and electricians are required onsite for connection, then proper installation is ensured, but installation cost and complexity increase
Solution Approach 1:
The patent designs the transfer switch and adaptor system to be self-configuring and self-protecting. The transfer switch automatically detects power source availability and performs switching operations without requiring skilled technicians. The system includes built-in safety features that automatically prevent improper connections, enabling DIY installation while maintaining installation quality
Solution Approach 2:
The transfer switch is designed as a universal device that can handle multiple functions: switching between utility and backup power, providing isolation protection, and enabling various adaptor configurations. This multi-functionality consolidates what would otherwise require multiple specialized devices and technicians into a single unit that can be installed and operated by non-experts
3Reliability
If inspections are required after connection, then safety compliance is ensured, but installation time and efficiency decrease
Solution Approach 1:
The transfer switch incorporates feedback mechanisms that automatically monitor the electrical connection status, power source availability, and system safety parameters. This continuous feedback allows the system to self-verify proper installation and operation, eliminating or reducing the need for manual inspections while maintaining safety compliance through automated monitoring and reporting
4Reliability
If utility power is terminated during connection, then safety is ensured, but power supply continuity is disrupted
Solution Approach 1:
The transfer switch acts as an intermediary that maintains continuous power supply by seamlessly switching between utility power and backup power source. During the connection process, the transfer switch can isolate the backup connection work from the live utility circuits while maintaining power flow through alternative paths, thereby ensuring both safety and power continuity
Solution Approach 2:
The system is designed to maintain continuous useful action (power supply) throughout the backup connection process. The transfer switch enables the utility power to continue flowing to the building while the backup power source is being connected and configured, ensuring no interruption to the building's power supply and eliminating the need for power termination
