Sliding Door Module Encapsulating Fasteners
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sliding door devices often result in damage to the sliding door due to protruding screws or nails during assembly, leading to costly repairs or replacements, and require complex and time-consuming assembly processes.
Innovation Solution
A module for accommodating a sliding door, comprising a prefabricated box with a guide device and adjustable components made from inexpensive materials like wood or metal, which prevents damage by encapsulating screws and allows quick assembly, using a guide rail system and adjustable height features to ensure stable and error-free sliding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If screws or nails are inserted into the outer walls of the lateral wall area, then the box structure can be assembled, but the ends of the screws or nails protrude into the side wall area clearance and scratch the sliding door
Solution Approach 1:
The patent introduces an intermediate protective element (the closed box structure formed by sides 51, 53, 57 and bottom 55) that mediates between the fastening screws/nails and the sliding door. The box acts as a barrier that contains the protruding fastener ends within its enclosed space, preventing them from contacting and scratching the sliding door while still allowing the fasteners to secure the box structure to the wall.
Solution Approach 2:
The box structure is assembled and closed before the sliding door is installed. By completing the enclosure of the box with all its sides and bottom in advance, the harmful protruding fastener ends are already contained and neutralized before they can cause damage to the sliding door during subsequent installation or operation.
2Ease of manufacture
If a multi-element frame or chassis is planked with outer walls, then the sliding door device can be constructed, but the assembly process becomes complex and time-consuming
Solution Approach 1:
The patent merges multiple separate structural elements (sides 51, 53, bottom 55, and potentially rear and front walls) into a single pre-assembled box structure. This integrated box unit functions as a complete structural module that can be installed as one piece, eliminating the need to assemble multiple separate frame elements and planking components on-site, thereby reducing assembly complexity and time.
Solution Approach 2:
The patent segments the sliding door device into distinct functional modules: the box structure (with sides, bottom, and walls) as one module, the sliding door mechanism as another, and the guide device as a separate component. This modular segmentation allows each module to be prepared independently and installed separately, simplifying the overall assembly process compared to constructing a monolithic multi-element frame.
3Productivity
If the box is prefabricated as a single unit, then assembly is quick and inexpensive, but the box must be designed to prevent protruding fasteners from scratching the sliding door
Solution Approach 1:
The box structure serves multiple functions simultaneously: it provides the structural framework for mounting the sliding door device, encloses and protects the internal components, contains the protruding fastener ends to prevent damage to the sliding door, and acts as a guide for the sliding door movement. By designing the box to fulfill multiple roles, the patent reduces the need for additional separate components, simplifying the overall structure despite its enclosed design.

AI summary
The module (3) has a box (5) comprising an upper end (501) and a lower end (502). A guiding device (7) is provided for a sliding door and attached to the upper end of the box, where the guiding device forms a closure of the box. The box has an opening (503) for accommodating the sliding door. A free space (57) for holding the sliding door is formed between side walls (51, 53) of the box. The guiding device has a guiding rail (71) and a wall part (73) that is arranged around the guiding rail, where the side walls and a base wall (55) of the box and/or the wall part are made from wood component. An independent claim is also included for a method for mounting a sliding door device for a sliding door.
