Appliance Identification for Plug Network Power Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Businesses face challenges in regulating and managing plug loads at workspaces, as simply announcing policies does not ensure compliance, and conducting inspections can be distracting and ineffective in maintaining compliance between inspections.
Innovation Solution
A method and system for managing a plug network based on appliance identification, where current and voltage measurements are used to compute power usage profiles, classify appliances, and generate power management action messages to control the operation of appliances, allowing businesses to monitor and manage which appliances are used and under what conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a business announces a company policy to regulate appliances, then employees are informed of the rules, but compliance is not ensured as employees might ignore or misinterpret the policy
Solution Approach 1:
The system continuously monitors power consumption patterns and provides real-time feedback to employees about their appliance usage. The power manager detects when prohibited appliances are connected and sends notifications to both employees and administrators, creating a closed-loop feedback system that ensures policy compliance without requiring manual inspections.
Solution Approach 2:
The system enables automatic enforcement of appliance policies through intelligent power management. The power manager autonomously identifies connected appliances based on power signatures, classifies them according to company policy, and automatically disconnects or alerts about prohibited devices without human intervention, making the compliance system self-regulating.
2Reliability
If a business conducts workspace inspections to enforce policy, then compliance can be verified, but it requires hiring inspectors and may be distracting and embarrassing to employees
Solution Approach 1:
The system replaces the mechanical inspection process with an automated electronic monitoring system. Instead of human inspectors physically visiting workspaces, the power manager uses electrical measurements and power signature analysis to automatically detect and classify appliances, eliminating the need for manual inspections while maintaining compliance verification.
Solution Approach 2:
The power manager acts as an intermediary between company policy and employee behavior. Rather than having inspectors directly interact with employees, the system uses power consumption data as an intermediary signal to indirectly monitor and enforce appliance policies, avoiding the social discomfort of direct inspection while maintaining oversight.
3Reliability
If inspectors walk-around to check compliance, then current policy violations can be detected, but there is no guarantee that employees will remain compliant between inspections
Solution Approach 1:
The power management system operates continuously, monitoring power consumption in real-time without interruption. Unlike periodic inspections, the system provides constant surveillance of appliance usage, ensuring that compliance is maintained at all times and not just during inspection moments, eliminating the time gaps where violations could occur.
Solution Approach 2:
The system detects and prevents policy violations before they become problematic by continuously monitoring power signatures. When a prohibited appliance is connected, the system immediately identifies it through power consumption analysis and can alert or disconnect the device before significant energy waste or safety issues arise, acting preventively rather than reactively.

AI summary
A method and system for managing a plug network based on appliance identification. In a basic implementation, when a new appliance is activated on the plug network, a power usage profile for the new appliance is computed based on current and voltage measurements. The new appliance is classified into an appliance class based on the power usage profile. A power management action message respecting the new appliance is generated based on the class and is outputted. By judiciously configuring the power management actions applicable to different appliance classes, a business can monitor which types of appliances are attached by employees to power outlets and/or set the terms and conditions under which such appliances operate.
