Vacuum Cleaner Power Management for Smart Grid Energy Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional power grids are centralized and one-directional, limiting consumers' access to real-time electricity price information and flexibility in electricity selection, which hampers energy efficiency and usage optimization.
Innovation Solution
A vacuum cleaner integrated with a smart grid system that includes a cleaner power management unit and display units for real-time power information, allowing users to select and confirm power supply based on usage needs, enabling two-way communication with the power supply network to optimize energy usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a centralized power grid system is used, then power supply stability is ensured, but consumer flexibility in electricity selection and access to real-time price information is limited
Solution Approach 1:
The power grid system is segmented into multiple distributed power sources rather than a single centralized source. The vacuum cleaner can selectively connect to different power sources (power plant, solar panel, wind turbine, fuel cell) based on real-time pricing and availability, enabling consumers to choose from multiple options while maintaining supply stability through the coordinated operation of these segmented sources.
Solution Approach 2:
The system implements real-time two-way communication between the vacuum cleaner and the power grid through an advanced metering infrastructure. This feedback mechanism provides consumers with real-time electricity price information and power availability status, enabling informed decisions about when and from which power source to draw electricity, thus improving consumer flexibility without compromising overall system reliability.
2Loss of information
If real-time power information display is implemented, then user awareness of power consumption and pricing is improved, but device complexity increases
Solution Approach 1:
The power management unit serves multiple functions simultaneously: it communicates with the advanced metering infrastructure to receive power information, processes pricing and availability data, controls the selection of power sources, and displays real-time information to the user. By consolidating these multiple functions into a single multi-functional unit, the system reduces overall device complexity while still providing comprehensive real-time power information to improve user awareness.
3Productivity
If high power consumption modes are used for cleaning tasks, then cleaning effectiveness is improved, but energy waste increases when full power is not needed
Solution Approach 1:
The vacuum cleaner implements dynamic power adjustment based on real-time power information from the grid and actual cleaning needs. The power management unit can dynamically switch between different power sources and adjust power consumption levels during operation. This allows the device to operate at high power when cleaning effectiveness is prioritized and switch to lower power modes or more economical power sources when full power is not needed, thereby reducing energy waste while maintaining cleaning productivity.
