Vehicle Door Unlocking Apparatus with Protruding Manual Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle door unlocking mechanisms face challenges in safely and cost-effectively unlocking doors during vehicle contact or power loss, as they can be vulnerable to unauthorized access and require professional assistance to reset.
Innovation Solution
A vehicle door unlocking apparatus featuring a release operator mechanically coupled to the door locker, which can be manually operated and protruded externally, utilizing a module mechanism with a spring-biased key cylinder that can be rotated and protruded for manual unlocking, allowing the door to be opened by an occupant or rescuer in emergency situations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an electronically controlled release mechanism is used to replace the manual door handle operation, then the ease of operation is improved, but the reliability deteriorates under vehicle contact or power loss conditions
Solution Approach 1:
The door unlocking system is segmented into two independent subsystems: an electronically controlled release mechanism for normal operation and a manual release operator for emergency conditions. This segmentation allows each subsystem to optimize for its specific function while ensuring overall system reliability across different operating conditions.
Solution Approach 2:
The system changes the operational parameter from electronic control to manual mechanical operation based on the operating condition. Under normal conditions, the electronic actuator provides easy operation; under emergency conditions (vehicle contact or power loss), the manual release operator provides reliable mechanical operation independent of electrical systems.
2Reliability
If a manual release mechanism is provided for emergency unlocking, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The manual release operator is merged with the existing electronic release mechanism and door locker system. Both the manual operator and electronic actuator connect to the same door locker, allowing either input to trigger the unlocking function. This merging approach adds redundancy for reliability while avoiding the need for completely separate mechanical systems.
Solution Approach 2:
The door locker mechanism serves multiple functions: it responds to both electronic actuation signals and manual mechanical input from the release operator. This multi-functionality allows a single component (the door locker) to handle both normal electronic unlocking and emergency manual unlocking, reducing overall system complexity.
3Object-affected harmful factors
If the release operator is kept inside the door, then the security is improved, but the ease of operation deteriorates during emergency situations
Solution Approach 1:
The release operator transitions from a static inside-door position to a dynamic configuration where it can protrude outward. The operator remains retracted inside the door during normal conditions to maintain security, but can be extended outward when needed for emergency manual operation, adapting its position based on operational requirements.
Solution Approach 2:
The door panel serves as an intermediary structure that houses the release operator and provides a controlled interface. The operator can protrude through a designated opening or slot in the door panel, allowing manual access from the outside while maintaining overall door integrity and security when retracted.

AI summary
A vehicle door unlocking apparatus is configured to, based on a state of a vehicle, unlock a door of the vehicle locked by a door locker. The vehicle door unlocking apparatus includes a release operator and a module mechanism. The release operator is disposed in the door and configured to unlock the door with a manual operation, and mechanically coupled to the door locker. The module mechanism is configured to cause the release operator to be disposed in the door such that the release operator is protrudable to the outside of the door.
