Retractable Ground Charging Access for Emergency Vehicle Entry Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Charging apparatuses installed in areas with restricted vehicle entry, such as parks, face challenges in balancing emergency use with the need to prevent non-emergency vehicle access, which can reduce convenience during emergencies.
Innovation Solution
A charging apparatus with a movable portion that can be raised and lowered using a raising device, controlled by a communication device and a control device. The control device permits raising the movable portion upon receiving request information for emergency use, such as during disasters or events, while prohibiting raising in non-emergency situations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the charging apparatus is installed in an area with restricted vehicle entry, then emergency use convenience is improved, but vehicle access control becomes problematic
Solution Approach 1:
The charging apparatus transitions between a hidden state (housed in the ground) and an operational state (raised above ground). This dynamic state change allows the system to provide convenient emergency access when needed while maintaining restricted access during normal conditions, resolving the contradiction between emergency convenience and access control.
2Ease of operation
If the movable portion is always raised for easy access, then charging convenience is improved, but unauthorized vehicle entry increases
Solution Approach 1:
The system dynamically adjusts the movable portion's position based on operational needs. During normal conditions, the movable portion remains housed in the ground, preventing unauthorized access. When emergency use is detected through the communication device, it raises to provide convenient charging access, thus resolving the contradiction between constant accessibility and access restriction.
3Object-affected harmful factors
If the charging apparatus is housed in the ground for access control, then unauthorized entry is prevented, but emergency accessibility is reduced
Solution Approach 1:
The communication device receives request information in advance to determine whether emergency use is needed. Based on this preliminary assessment, the control device pre-positions the movable portion in the raised state before charging begins, ensuring immediate accessibility during emergencies while maintaining ground-housed positioning during normal conditions to prevent unauthorized access.
4Productivity
If the movable portion is raised frequently for normal use, then charging availability is improved, but system reliability for emergency use decreases
Solution Approach 1:
The control device uses feedback from the communication device regarding emergency status to control the raising and lowering of the movable portion. This feedback mechanism ensures the system only raises for genuine emergency cases, maintaining high reliability for emergency use while providing sufficient charging availability when actually needed, preventing unnecessary raising that would compromise emergency readiness.

AI summary
A charging apparatus is installed in an area in which entry of a vehicle is restricted. The charging apparatus includes: a movable portion including a connection device connectable to an energy storage device; a raising device configured to raise and lower the movable portion between a first state and a second state; a communication device; and a control device. The first state is a state in which the movable portion is housed in the ground, and the second state is a state in which the movable portion is exposed on the ground and the energy storage device and the connection device are connectable together. The control device is configured to control the raising device using information received via the communication device, and permits raising the movable portion when the movable portion is in the first state and the control device receives request information requesting emergency use of the charging apparatus.
