Vehicle Door Lock Retainer Ring for Break-In-Resistant Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor vehicle door locking systems are vulnerable to break-ins, suffer from quality defects leading to malfunctions, and are complex to assemble, offering insufficient security and durability.
Innovation Solution
An opening control device with a support and retaining member featuring a ring and slide mechanism that rotates between positions to secure a lock, incorporating a sliding connection and stop means for robust assembly and resistance to break-ins, using a guide rail and slider for easy installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a lock is integrated into the opening mechanism, then the locking system is compact, but the security against break-in attempts is insufficient
Solution Approach 1:
The locking system is divided into separate functional components: the opening control device (handle mechanism) and the lock body are positioned at different locations on the door. The handle mechanism is integrated into the door panel while the lock body is mounted separately on the door edge, connected by a rod or cable. This segmentation allows each component to be optimized for its specific function while improving overall security.
Solution Approach 2:
A rod or cable acts as an intermediary element connecting the opening control device to the lock body. This intermediary transmits the mechanical force from handle operation to the lock mechanism, allowing the lock to be positioned away from the handle assembly while maintaining functional connection. This intermediary connection enhances security by preventing direct manipulation of the lock through the handle mechanism.

3Volume of moving object
If the lock is integrated into the opening control device, then the structure is compact, but the assembly process is complex and incomplete installation occurs
Solution Approach 1:
The locking system is divided into separate functional components: the opening control device (handle mechanism) and the lock body are positioned at different locations on the door. The handle mechanism is integrated into the door panel while the lock body is mounted separately on the door edge, connected by a rod or cable. This segmentation allows each component to be optimized for its specific function while improving overall security.
Solution Approach 2:
The lock body is pre-mounted on the door edge with its mounting plate and fastening means before the opening control device is assembled. This preliminary positioning ensures that the lock is securely installed and properly aligned before the handle mechanism is connected, preventing incomplete installation and ensuring that all security features are properly configured.
