Sliding Door Control Device Prevents Charging Connector Contact
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle systems do not adequately prevent contact between sliding doors and energy supply connectors during charging, which can occur in both electrified and non-electrified vehicles, posing risks of damage and inefficiency.
Innovation Solution
A control device is integrated into the vehicle to restrict the movement of the sliding door when an energy supply connector is connected to the energy supply port, preventing contact between the sliding door and the energy supply connector.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the sliding door is allowed to move freely during charging, then ease of operation is improved, but the risk of contact between the sliding door and energy supply connector increases
Solution Approach 1:
The control device detects the connection state of the energy supply connector in advance and proactively restricts sliding door movement before contact can occur. This preliminary protective action prevents the harmful event rather than responding after contact happens.
Solution Approach 2:
The control device acts as an intermediary between the sliding door control system and the energy supply connector status. It receives information about connector connection and translates this into appropriate sliding door movement restrictions, mediating between operational freedom and safety requirements.
2Reliability
If the movement of the sliding door is restricted when the energy supply connector is connected, then safety is improved, but ease of operation deteriorates
Solution Approach 1:
The sliding door control system dynamically adjusts its behavior based on the connection state of the energy supply connector. When the connector is disconnected, full movement freedom is allowed; when connected, movement is restricted. This dynamic adaptation resolves the contradiction by making the restriction conditional rather than permanent.
Solution Approach 2:
The control device continuously monitors the connection state of the energy supply connector and uses this feedback information to adjust sliding door movement permissions. This closed-loop control ensures that safety restrictions are applied only when necessary (when connector is connected) and removed when safe to operate (when connector is disconnected).

AI summary
A vehicle includes a sliding door, an energy storage device for storing energy used to generate driving force for the vehicle, an energy supply port located in a range in which the sliding door is movable, the energy supply port being configured to receive energy provided from an external energy supply source and supply energy to the energy storage device, and a control device that restricts movement of the sliding door when an energy supply connector is connected to the energy supply port.
