Smart Socket Standby Power Detection for Appliance Energy Saving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Smart sockets lack an effective method to reduce energy consumption of appliances plugged into them, as they do not efficiently differentiate between power on and power standby modes, leading to unnecessary energy usage.
Innovation Solution
Incorporating a meter in smart sockets to measure energy consumption over a baseline period, identifying appliances in power standby mode, and automatically turning off the socket receptacles after a predetermined time or when energy consumption exceeds a threshold, thereby reducing energy usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If smart sockets continuously supply power to appliances in standby mode, then appliances remain ready for immediate use, but energy consumption increases unnecessarily
Solution Approach 1:
The system performs preliminary analysis during a baseline period to learn appliance power consumption patterns and identify standby modes. This preliminary action enables the system to predict when appliances will be needed and pre-position them in appropriate power states, reducing unnecessary standby energy consumption while maintaining readiness when required
Solution Approach 2:
The system continuously monitors power consumption and provides feedback to the supervisor, which compares actual consumption against learned patterns to identify when appliances are in standby mode. This feedback loop enables dynamic adjustment of power supply, turning off sockets supplying standby appliances and turning them back on when needed, thus reducing energy waste while maintaining operational readiness
2Use of energy by moving object
If smart sockets turn off power to appliances in standby mode, then energy consumption is reduced, but appliances may not be ready when needed
Solution Approach 1:
During the baseline period, the system performs preliminary action by learning and storing the normal power consumption patterns of each appliance. This预先建立的基准数据使系统能够快速识别异常的低功耗状态（待机模式），并在切断电源前就已经掌握了 appliances 的使用规律，从而在保证可靠性的前提下实现节能
Solution Approach 2:
The system implements periodic monitoring of power consumption and periodic comparison against baseline patterns. This periodic action allows the system to continuously detect standby modes and adjust power supply accordingly, while also periodically verifying that appliances remain available when needed, thus balancing energy savings with reliability
3Use of energy by moving object
If smart sockets monitor and analyze power consumption patterns, then energy savings are achieved, but system complexity increases
Solution Approach 1:
The system implements self-service by having the supervisor automatically learn baseline power patterns during an initial period and autonomously identify standby modes through comparison with these patterns. The system serves itself by automatically making decisions about when to turn off sockets without requiring manual configuration or complex user intervention, thus achieving energy savings while keeping the control logic relatively simple
Solution Approach 2:
The system performs preliminary action by establishing baseline power consumption patterns during an initial learning period. This预先建立的数据模型简化了后续的监控和决策过程，使系统能够通过简单的模式匹配来识别待机状态，而不需要复杂的实时分析算法，从而在实现节能的同时控制了系统复杂度

AI summary
Energy consumption may be reduced by tracking a measure of baseline energy over time in order to determine which of the one or more appliances have a power on mode and a power standby mode based at least in part on the measure of baseline energy delivered to each of the appliances during the baseline time period, wherein the power standby mode consumes less power than the power on mode. During subsequent operation, the supervisor identifies when an appliance is in a power standby mode, and turns off the socket receptacles of the smart sockets that corresponds to those appliances identified as being in their power standby mode.
