EV Charging Schedule Display with Distinct Icon Shapes and Colors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Displaying a charging schedule for multiple days in electric vehicles makes it difficult for users to intuitively understand which charging reservation type is set to each charging plan when multiple types are present.
Innovation Solution
A display device that uses icons with different shapes and colors to represent various charging reservation types, allowing users to easily distinguish between charging plans with start and finish time specifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a charging schedule for multiple days is displayed on a single screen, then user convenience is improved, but it becomes difficult to intuitively understand which charging reservation type is set to each charging plan
Solution Approach 1:
The patent applies different colors to icons representing different charging reservation types (e.g., Type 1, Type 2, Type 3). This color-coding system allows users to quickly distinguish between various charging plan types at a glance, resolving the information identification problem while maintaining the multi-day display format on a single screen.
Solution Approach 2:
The patent uses asymmetric icon designs where each charging reservation type is represented by a distinct icon shape or configuration. This asymmetry in icon design enables users to differentiate between charging plan types visually, preventing information loss while preserving the compact multi-day schedule display.
2Quantity of substance
If multiple charging reservation types are displayed with detailed information, then information completeness is improved, but visual distinction and intuitive understanding deteriorate
Solution Approach 1:
The patent segments the display into distinct visual elements - each charging plan is represented by a separate icon with unique color and shape characteristics. This segmentation allows multiple charging reservation types to be displayed simultaneously with complete information while maintaining clear visual distinction through differentiated icon properties.
Solution Approach 2:
The patent applies local quality by giving each icon specific visual properties (color, shape, size) that correspond to its charging reservation type. This localized differentiation ensures that each charging plan can be instantly recognized by its unique visual characteristics, maintaining both information completeness and visual distinguishability.

AI summary
A display displays a charging schedule of an electricity storage device, using multiple icons representing charging plans for multiple days. When multiple charging reservation types are specified for charging plans for multiple days, a controller displays icons on the display so that at least one of shapes and colors of the icons are different for each charging reservation type.
