Information Presentation Apparatus for Real-Time Electricity Consumption Visualization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users cannot effectively track changes in total electricity consumption when adjusting the operating periods of electrical appliances, as existing systems do not provide real-time updates or user-specific feedback on these changes.
Innovation Solution
An information presentation apparatus and method that displays total and operating period images on a terminal device, allowing users to visualize and update electricity consumption in real-time based on changes in appliance operating periods, with features like image generation and calculation of updated consumption values.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If existing systems display time series of electricity consumption, then users can know the time series of electricity consumption of electrical appliances, but users cannot effectively track changes in total electricity consumption when adjusting operating periods
Solution Approach 1:
The system displays a first total electricity image showing the current time series of total electricity consumption, then upon user input specifying a changed operating period, it generates and displays a second total electricity image showing the predicted time series after the change. This feedback mechanism allows users to see the impact of their adjustments on total electricity consumption, resolving the information loss problem while maintaining ease of operation through intuitive visual comparison.
2Productivity
If the system displays detailed operating period images for each appliance, then users can see individual appliance data, but the system cannot provide real-time updates when operating periods change
Solution Approach 1:
The system pre-calculates and stores the relationship between operating periods and total electricity consumption based on historical data and appliance characteristics. When a user specifies a changed operating period, the system quickly retrieves and displays the corresponding second total electricity image without requiring complex real-time calculations, thus achieving rapid updates while keeping the system relatively simple.

AI summary
An information presentation apparatus includes: a storage storing first image information for use in screen display; and an information processor reading the first image information from the storage and executing first screen display based on the first image information. After executing the first screen display, the information processor generates second image information for use in screen display based on user's operation, stores the generated second image information in the storage, and executes second screen display based on the second image information read from the storage.
