EV Charging Signage Content Matching for Waiting-Time Use
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The long charging time of electric vehicles compared to gasoline-powered vehicles leads to inefficient use of waiting time, and existing technologies do not effectively utilize this time due to changing facility situations.
Innovation Solution
A digital signage device that acquires waiting time, selects candidate facilities based on surrounding environment information, and displays relevant content to enhance user experience during charging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If charging time is reduced to match gasoline vehicle refueling time, then user convenience is improved, but charging infrastructure capability is insufficient
Solution Approach 1:
The patent converts the harmful factor of long charging time into a beneficial opportunity by providing entertainment content during the waiting period. The digital signage system offers movies, games, and other content to make users productive of their waiting time, thereby compensating for the inability to reduce charging time physically.
2Productivity
If facility information is provided statically, then information delivery is simple, but facility utilization efficiency deteriorates due to changing congestion situations
Solution Approach 1:
The patent implements dynamic information delivery by continuously updating facility congestion status and matching content recommendations in real-time. The system adjusts content selection based on current facility situations, transforming static information delivery into a dynamic adaptive system that responds to changing conditions.
Solution Approach 2:
The system incorporates feedback mechanisms by monitoring facility usage patterns and user interactions with the digital signage. This feedback loop enables the system to learn from actual usage data and optimize content recommendations, thereby improving facility utilization efficiency through data-driven decision making.
3Ease of operation
If content is presented without considering surrounding environment, then content delivery is simple, but user satisfaction deteriorates due to mismatched recommendations
Solution Approach 1:
The patent applies local quality by customizing content recommendations based on specific surrounding environmental factors such as facility type, congestion level, and user context. Rather than uniform content delivery, the system adapts content selection to local conditions at each charging facility, ensuring relevance and improving user satisfaction.

AI summary
A content management unit acquires a waiting time when a user waits to charge an in-vehicle battery, extracts candidate facilities available to the user in accordance with the acquired waiting time. The content management unit acquires surrounding environment information indicating an environment around the facility for charging the in-vehicle battery. The content management unit selects at least one candidate facility from the candidate facilities in accordance with the acquired surrounding environment information. The content management unit identifies presentation content related to the selected candidate facility. A display processing unit displays the presentation content identified by the content management unit.
