Power Management Device Appliance-Level Consumption Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power management systems cannot accurately measure and display power consumption data for individual electrical appliances, as they group data by branch breakers rather than appliances, making it impossible to provide useful consumption information to users.
Innovation Solution
A power management device that obtains and displays power consumption information from multiple electrical appliances, groups them by attribute layers, and allows users to select and expand information for specific appliances, prioritizing data display based on allocated attribute information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If power consumption is measured for each branch breaker, then measurement coverage is achieved, but data granularity for individual appliances is lost
Solution Approach 1:
The patent segments the aggregated branch breaker data into individual appliance consumption data by introducing multiple classification dimensions (appliance type, room, usage time) and using data mining techniques to allocate power consumption to specific appliances based on their operational characteristics and usage patterns
Solution Approach 2:
The patent introduces an intermediary data processing layer that uses attribute information (appliance type, room, usage time) as mediators to bridge the gap between branch breaker measurements and individual appliance consumption, enabling accurate data allocation without direct appliance-level meters
2Device complexity
If power consumption data is grouped by branch breakers, then data collection is simplified, but usability for energy saving is reduced
Solution Approach 1:
The patent segments the flat branch breaker data structure into hierarchical groups based on multiple attributes (appliance type, room, usage time), creating organized data categories that are both easy to manage and highly useful for energy saving decisions
Solution Approach 2:
The patent adds multiple classification dimensions (appliance type, room, usage time) to the data structure, transforming one-dimensional branch breaker data into multi-dimensional grouped data that enables comprehensive energy management while maintaining simple collection mechanisms
3Adaptability or versatility
If detailed appliance-level power data is provided, then energy management capability is enhanced, but data processing complexity increases
Solution Approach 1:
The patent performs preliminary grouping and classification of power consumption data by appliance type, room, and usage time before detailed analysis, pre-organizing the data structure to enable versatile energy management operations without requiring complex real-time processing
Solution Approach 2:
The patent segments the data processing task into distinct stages: data collection, multi-dimensional grouping, attribute-based classification, and analysis, with each stage handling specific aspects of the data to manage complexity while delivering comprehensive energy management capabilities

AI summary
A management system for managing measurement information on power consumption in at least one electrical appliance which is associated with at least one meter includes a first storage module configured to store measurement information transmitted from each of the at least one meter associated with the at least one electrical appliance, on power consumption in the at least one electrical appliance, in correspondence with the at least one meter. The management system also includes a second storage module configured to store history information on association between each of the at least one meter and the at least one electrical appliance. An information output module may be configured to output, in response to selection of an electrical appliance, as electric power information on the selected electrical appliance, information on power consumption in the selected electrical appliance brought in correspondence with a time period regardless of a meter associated with the selected electrical appliance, which is based on the measurement information in the first storage module and the history information in the second storage module.
