Swing-Sliding Door Locking Mechanism Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pivoting sliding door systems for passenger transport vehicles require additional components like door tree tubes and power sources for locking, which increase complexity, cost, and space usage, and lack a reliable locking mechanism for the lower side edge without these components.
Innovation Solution
A guiding and locking device that integrates a pivoting lever and link slide with a locking section, allowing secure locking of the door leaf without a door tree tube or additional drive mechanisms, using a compact design with a roller pivot lever and guide elements to ensure secure engagement and disengagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a door tree tube and additional drive mechanisms are used for locking, then reliable locking of the door leaf is achieved, but device complexity and cost increase
Solution Approach 1:
The locking function is merged with the existing drive device that causes pivoting movement of the door leaf. The locking mechanism is integrated into the drive device structure, eliminating the need for separate locking drive mechanisms and door tree tubes, thereby reducing complexity while maintaining reliable locking
Solution Approach 2:
The drive device is designed to perform multiple functions: both causing pivoting movement of the door leaf and enabling locking. By making the drive device universal, the patent eliminates the need for separate dedicated locking mechanisms, reducing overall system complexity while ensuring reliable locking through the same actuator
2Reliability
If a door tree tube is used for locking, then locking function is provided, but installation space and cost increase
Solution Approach 1:
The locking mechanism is merged with the drive device structure, eliminating the need for separate door tree tubes. This integration significantly reduces the installation space required while maintaining the locking function through the compact combined design
3Reliability
If additional drive mechanisms are used for locking, then secure locking is achieved, but cost and complexity increase
Solution Approach 1:
The locking function is merged with the existing drive device, eliminating the need for additional separate drive mechanisms. This integration reduces manufacturing costs by reducing the number of components that need to be produced, assembled, and tested, while maintaining secure locking through the unified design
4Device complexity
If locking mechanism is integrated into drive device, then device complexity and cost are reduced, but locking reliability may be compromised
Solution Approach 1:
The locking function is merged with the drive device in such a way that the same actuator that provides pivoting movement also enables locking. This integration maintains reliability because the locking action is directly coupled to the drive mechanism's motion, ensuring positive engagement without requiring separate complex locking systems
Solution Approach 2:
The drive device automatically provides locking function as part of its normal operation. The locking mechanism is designed to engage automatically through the pivoting motion itself, without requiring additional control systems or separate actuation, thereby maintaining reliability through self-contained operation

AI summary
In a guide and locking device of a swing-sliding door system of a vehicle, in particular a passenger transport vehicle, comprising a pivot lever (20) guided at one end on an associated door leaf (1) of a door leaf (27), and which is attached at its other end to a locking element pivotably mounted in a guide and locking part (6) fixedly arranged on the door frame (7) and/or on the vehicle floor (8), a solution is to be provided that enables secure locking of a door leaf in a simple and cost-effective manner. This is achieved by the guide and locking part (6) having a first guide element (9) with a first cam opening (14) formed therein, in which the locking element, designed as a cam slider (12), is slidably and pivotably guided.
