Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional charge-discharge systems struggle to provide a clear understanding of power exchange between power systems, vehicle energy storage apparatuses, and power loads, making it difficult to grasp the power flow effectively.
Innovation Solution
A charge-discharge system that includes an acquisition unit to gather power amount information, a generation unit to create display data for a calendar view showing charge-side and discharge-side power amounts, and a transmission unit to display this data on a device, enabling easy visualization of power exchange.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If power exchange data is collected and processed in conventional charge-discharge systems, then the system can track power flow, but it remains difficult to grasp and understand the power exchange patterns
Solution Approach 1:
The patent creates a simplified calendar copy of power exchange data that replicates the essential information in an easily understandable format. The calendar screen displays power exchange patterns as visual data corresponding to date periods, allowing users to grasp power flow without complex raw data processing
Solution Approach 2:
The patent transforms one-dimensional numerical power exchange data into a two-dimensional calendar visualization where power amounts are represented both temporally (across date periods) and magnitudinally (through visual representation), making the data intuitively comprehensible
2Measurement precision
If detailed power amount data is displayed for each period, then power exchange can be precisely tracked, but the information becomes difficult to grasp intuitively
Solution Approach 1:
The patent uses visual representation with different colors or shades to indicate power exchange amounts, where the visual intensity or color variation corresponds to the power amount magnitude. This allows precise power data to be conveyed through intuitive visual cues rather than raw numbers
Solution Approach 2:
The patent adds a visual dimension to numerical power data by displaying power amounts as graphical elements on the calendar screen, where the size, color, or position of visual elements represents power magnitude, making precise data intuitively graspable
