Programmable Relay Switch Assembly for Standby Power Cutoff
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies fail to provide a system that automatically disconnects and reconnects power supply to electronic devices in a standby state without requiring power usage detection, leading to wasteful standby power consumption.
Innovation Solution
An energy saving system utilizing a programmable relay switch assembly installed between a main electrical panel and a subpanel, which automatically disconnects and reconnects power to outlets based on predefined times to prevent standby power usage, powered by the main panel or an independent source.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If a detection-based control system is used to manage standby power, then power can be cut off when devices are not in use, but the system complexity increases and requires additional sensing components
Solution Approach 1:
The patent extracts the power management function from complex detection systems and implements it through a simple programmable timer-based relay switch assembly that automatically cuts power to outlets based on predefined schedules, eliminating the need for sophisticated sensing components while achieving energy savings
Solution Approach 2:
The relay switch assembly is programmed with predetermined time periods to automatically disconnect and reconnect power without requiring external detection or user intervention, allowing the system to self-regulate power distribution based on anticipated usage patterns
2Ease of operation
If power is continuously supplied to electronic devices, then devices remain ready for immediate use, but standby power is wasted during periods when devices are not needed
Solution Approach 1:
The system is programmed with predetermined time periods that anticipate when devices will be needed, reconnecting power before actual usage begins. This preliminary action ensures devices are ready for use while minimizing the time power is supplied, thereby reducing standby consumption
3Loss of energy
If detection-based systems are implemented to monitor power usage, then standby power can be identified and eliminated, but the cost and complexity of detection components increase
Solution Approach 1:
The patent replaces expensive, complex detection systems with an inexpensive programmable relay switch assembly that uses simple timer-based logic to achieve power management, significantly reducing system cost and complexity while maintaining energy savings

AI summary
The present invention discloses an energy saving system and method for use in a residential or commercial building. The system includes a main electrical panel, a relay switch assembly, an electrical subpanel, and a power outlet. The power outlet is connected to the subpanel. The relay switch assembly connects the main electrical panel to the electrical subpanel and includes a wirelessly programmable relay switch that operates to automatically disconnect and reconnect an electrical current from the main panel to the subpanel and power outlet to prevent an electronic device, that is turned off and plugged into the outlet, from using external standby power.
