Swinging Door System with Single Support Rod
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pivoting sliding door systems for passenger transport vehicles require separate support rods for each door leaf, increasing the overall height of the storage unit and necessitating additional drive mechanisms for locking, which complicates the design and increases costs.
Innovation Solution
A compact pivoting sliding door system design where both door leaves are mounted on a single support rod, utilizing an angled vertical bracket and a guiding and locking device with a link slide mechanism that allows independent locking of the door leaf without additional drive components, integrated into the door frame for space and weight savings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate support rods are provided for each door leaf, then each door leaf can be independently supported and locked, but the overall height of the storage unit increases
Solution Approach 1:
The patent merges the support function for multiple door leaves into a single support rod. The support rod is designed to accommodate multiple door leaves simultaneously through mounting brackets that can be positioned at different locations along the rod, eliminating the need for separate support rods for each door leaf while reducing the overall height of the storage unit.
Solution Approach 2:
The single support rod serves multiple functions: it supports multiple door leaves, provides mounting points for locking mechanisms, and enables both pivoting and sliding movements for all door leaves. The universal design allows the same rod to handle various door configurations without requiring additional specialized components for each door.
2Reliability
If additional drive mechanisms are added for locking the door leaf, then secure locking is achieved, but the device complexity and cost increase
Solution Approach 1:
The locking mechanism is designed to utilize the existing pivoting and sliding motion of the door leaf to automatically engage and disengage the lock. As the door leaf moves into its closed position, the locking element automatically engages with the support rod or door frame, eliminating the need for separate drive mechanisms. The system self-locks through its own movement characteristics.
Solution Approach 2:
The patent introduces a locking element that acts as an intermediary between the door leaf and the support rod/door frame. This locking element translates the mechanical motion of the door leaf into automatic engagement without requiring additional motors or actuators. The locking element serves as a mechanical mediator that converts operational movement into secure locking.
3Strength
If multiple components are used for mounting door leaves on support rods, then secure mounting is achieved, but the design complexity and manufacturing cost increase
Solution Approach 1:
The mounting system is segmented into modular components: mounting brackets that can be positioned at different locations on the support rod, and attachment points on the door leaves. This segmentation allows for flexible configuration while using standardized, easily manufactured components. Each bracket can be independently positioned and secured, simplifying both design and manufacturing.

AI summary
In a swing-sliding door system (1) of a vehicle, in particular a passenger transport vehicle, which comprises at least one door leaf (2, 3) slidably mounted on a horizontal support rod (7) of a bearing unit (9), which can be extended from a door opening (4) to open and, in its open position, is longitudinally displaceable along an outer wall (8) of the vehicle and, in the reverse of movement, closes the door opening (4) again, wherein the bearing unit (9) is extendable and retractable perpendicular to the direction of movement of the at least one door leaf (2, 3) and has a locking shaft (32) parallel to the support rod (7), which extends and retracts the bearing unit (9) via a linkage mechanism, and an electric geared motor (33) which is connected to the locking shaft (32) and drives it rotationally, and which has a guide and locking device comprising a pivot lever (66) which, with one end, is attached to the associated at least one door leaf (2, 3).3) guided and attached at its other end to a locking element which is pivotably mounted in a guide and locking part (52) fixedly arranged on the door frame (53) and/or on the vehicle floor (54), a solution is to be created that provides a simplified and improved swing-sliding door system in a structurally simple and cost-effective manner. This is achieved by arranging the bearing unit (9) and the support rod (7) above the door opening (4) and recessing them into the vehicle interior, and by connecting at least one door leaf (2, 3) to the support rod (7) via an angled vertical bracket (14, 15), and by the guide and locking part (52) having a first guide element (55, 77) with a first cam opening (59, 82) formed therein, in which the locking element, designed as a cam slide (58, 78), is slidably and pivotably guided.
