Solution Overview
Problem
Existing wall structures for sliding and slide-swinging doors face challenges in modularity, standardization, and adaptability to different dimensions and wall thicknesses, leading to high storage costs and limitations in creating non-standard structures.
Innovation Solution
A modular wall structure system with elongated constructional elements and interchangeable components, including rail sections and end closure members, that can be easily assembled and adapted to fit various door sizes and wall thicknesses, using coupling systems like dovetail joints and spring clips for secure attachment to the peripheral frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If preformed elements of large dimensions are used to support sliding doors, then the structural integrity and door housing capability are improved, but the transport difficulty, weight, and handling complexity increase significantly
Solution Approach 1:
The wall structure is divided into separate modular components: vertical uprights, horizontal crosspieces, and door housing elements can be assembled independently. This segmentation allows each component to be manufactured and transported separately, then assembled on-site to form the complete wall structure with integrated door housing.
Solution Approach 2:
The door housing structure is nested within the wall structure framework. Vertical elements are inserted into correspondingly shaped holes in horizontal elements, creating a nested assembly where the door housing case is formed by fixing vertical elements to both top and bottom longitudinal elements, which are themselves part of the peripheral frame.
2Adaptability or versatility
If preformed elements of large dimensions are used to support sliding doors, then the door housing capability is improved, but the storage costs and space requirements increase due to the need to stock elements of all possible dimensions
Solution Approach 1:
The modular components are designed with standardized connection interfaces (correspondingly shaped holes, insertion elements) that allow the same basic elements to be used across different wall structure configurations. A limited set of universal components can accommodate various door sizes and wall thicknesses through different assembly arrangements rather than requiring dedicated preformed elements for each dimension.
Solution Approach 2:
The wall structure employs adjustable and configurable elements that can be adapted to different dimensions. The vertical elements can be positioned at various locations along the horizontal elements, and the structure can be configured for single or double doors, allowing one set of components to serve multiple application scenarios.
3Manufacturing precision
If rigid wall structures with predetermined dimensions are used, then the manufacturing precision and structural stability are improved, but the adaptability to non-standard dimensions and configurations is lost
Solution Approach 1:
The wall structure is segmented into modular components with standardized connection interfaces. This allows precise manufacturing of individual elements while maintaining adaptability through various assembly configurations. The segmentation enables the structure to be customized for different dimensions by selecting and arranging appropriate modules rather than requiring custom-made entire structures.
Solution Approach 2:
Different parts of the wall structure can be configured with different properties. The modular design allows specific sections to be adjusted for local requirements (different wall thicknesses, door positions, access points) while maintaining overall structural integrity through standardized connection mechanisms.
4Strength
If complex processing and specific positioning requirements are imposed on structural elements, then the structural stability and door support capability are improved, but the ease of assembly and manufacturing complexity decrease
Solution Approach 1:
The connection interfaces (correspondingly shaped holes, insertion elements with fork-like structures) are pre-formed during manufacturing of individual components. This preliminary action ensures proper alignment and structural integrity without requiring complex field processing. The vertical elements are pre-configured with fork-like ends to engage with horizontal elements, and wall panels are pre-drilled with holes for screw insertion.
Solution Approach 2:
The modular components are designed to self-align and self-assemble through their complementary geometric features. The correspondingly shaped holes and insertion elements guide proper positioning during assembly, reducing the need for precise manual alignment. The structure essentially assembles itself through the inherent geometry of the connection interfaces.

AI summary
In an improved wall structure with or for sliding door or slide-swinging door, a rail section (21) allows a sliding movement of a sliding, or slide-swinging, or folding door (16). A first coupling system (90), located at the first extremity (200) of the rail section (21), interacts with a second coupling system (91) located at a first side (71) of an end closure member (70), coupling the latter to the rail section (21). A third coupling system (92), located at a second side (72) of the end closure member (70) distal form the first side (71), interacts with a fourth coupling system (93) located at a second side (82) af an additional member (80) distal from a first side (81) of the additional member (80) itself. The additional member (80) is either a finishing plug or a connecting part with its first side (81) provided with a related fifth coupling system (94) for coupling the additional member (80) to other parts of the wall structure.
