Motor Vehicle Door Lock Device with Electric Release Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor vehicle door lock devices require unlocking the locking mechanism and then using the outside handle to open a locked door, which is not swift, and during a panic situation, the door cannot be opened quickly as the locking mechanism does not switch to the unlocking state promptly.
Innovation Solution
A motor vehicle door lock device equipped with an electrically operated external switch, capacitive touch switches, and an electronic control unit that authenticates the user's ID signal via a transmitter, allowing the door to be opened swiftly with the outside handle by controlling the locking mechanism's state through a releasing motor, even if the locking mechanism is in a locked state, and preventing panic situations by ensuring secure unlocking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the locking mechanism is locked to secure the door, then security is improved, but the door cannot be opened swiftly from the outside
Solution Approach 1:
The system performs preliminary authentication of the ID signal before allowing door opening. When authentication succeeds, the locking mechanism is preemptively switched to the unlocking state, enabling swift door opening without manual unlocking operations.
Solution Approach 2:
The patent replaces the traditional mechanical key-based unlocking system with an electronic authentication system using ID signals and capacitive touch switches. This substitution enables rapid electronic unlocking that eliminates the need for manual key insertion and turning operations.
2Reliability
If the locking mechanism is locked to prevent unauthorized access, then security is improved, but during panic situations the door cannot be opened quickly
Solution Approach 1:
The system continuously monitors authentication status and maintains the locking mechanism in an unlocked state once authentication is confirmed, so that during panic situations the door can be opened immediately without additional unlocking actions.
Solution Approach 2:
The control unit acts as an intermediary between the authentication system and the locking mechanism. It processes ID signals and automatically controls the locking state, eliminating the need for manual intervention during emergency situations.
3Speed
If multiple authentication methods (external switch, capacitive touch switches) are added to enable swift door opening, then door opening speed is improved, but device complexity increases
Solution Approach 1:
The control unit is designed to handle multiple authentication methods (external switch signals and capacitive touch switch signals) through a unified control logic, enabling swift door opening through various input methods while avoiding the need for separate control circuits for each input type.

AI summary
A motor vehicle door lock device comprises a locking mechanism, a locking motor, an electric release mechanism, an opening lever, and an outside handle. An ECU includes an authenticating portion. When the authenticating portion authenticates a signal from a transmitter and the locking mechanism starts switching from a locking state to an unlocking state by the locking motor, ECU controls a releasing motor so that the electric release mechanism is actuated because a switch detects door-opening action of the outside handle. The locking mechanism is switched to the unlocking state without contacting the opening lever from a direction where the opening lever cannot be actuated. A locked door can be opened with the outside handle at a single action and prevents a panic.
