Vehicle Door Locking Structure for Single-Input Bidirectional Opening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door locking systems for vehicles, particularly in autonomous vehicles, require improved mechanisms for bidirectional access, necessitating a locking structure that can efficiently unlock and open doors simultaneously with a single input, addressing the need for enhanced user convenience and accessibility.
Innovation Solution
A door locking structure featuring a multi-locking unit that includes an input unit, a controller, and a drive unit, allowing for simultaneous unlocking of auxiliary and main lockers through mechanical and electrical inputs, enabling bidirectional door opening by applying driving force to both upper and lower doors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a multi-locking unit is implemented for bidirectional door opening, then door security and control capability are improved, but device complexity increases
Solution Approach 1:
The locking unit is divided into multiple independent lockers (first locker, second locker, third locker, fourth locker) that can be controlled separately. Each locker handles a specific door and direction combination, allowing the system to achieve bidirectional opening capability while maintaining manageable complexity through modular design.
Solution Approach 2:
The locking unit is designed as a universal system that can lock and unlock doors in multiple directions (upward, downward, forward, backward) using a single integrated structure. This multi-functional design allows one locking unit to replace what would traditionally require multiple separate locking mechanisms for different door configurations.
2Ease of operation
If simultaneous unlocking of multiple lockers is implemented through one input unit, then ease of operation is improved, but control complexity increases
Solution Approach 1:
Multiple locking mechanisms (first locker, second locker, third locker, fourth locker) are merged into a single integrated locking unit that responds to one input signal. The controller coordinates all lockers simultaneously, allowing a user to unlock all doors with a single input operation while the control system manages the complexity of coordinating multiple lockers.
Solution Approach 2:
The locking unit automatically determines which lockers need to be unlocked based on the single input received. The controller intelligently activates the appropriate lockers (first, second, third, or fourth) without requiring the user to specify individual door selections, making the system self-servicing and easeful to operate.
3Adaptability or versatility
If mechanical and electrical driving inputs are integrated, then functionality is improved, but device complexity increases
Solution Approach 1:
The locking unit is designed to accept multiple types of input signals (mechanical driving input and electrical driving input) through a single integrated structure. This universal input capability allows the system to function with different actuation methods while maintaining a unified locking mechanism that handles both input types without requiring separate systems for each input method.

AI summary
A door locking structure includes a door located at a side of a vehicle, a locking unit provided at the door, an input unit configured to apply unlocking input to the locking unit, and a controller configured to receive the input through the input unit and to unlock the locking unit. The controller is configured to integrally unlock the locking unit in response to the input through the input unit.
