Sliding Door Curved Guide Frame Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sliding door systems face difficulties in moving between closed and parallel positions due to complex assembly requirements and manufacturing tolerances, which can lead to malfunctions and noise issues.
Innovation Solution
A sliding door design featuring a closing element with a curved guide fixed to a vertical frame profile, allowing for easy assembly and adjustment, with a screw groove for hidden fastening and elastic stops to minimize noise, and multiple control elements driven by drive rods for smooth operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a locking element with curved guide is fixed to the sliding sash, then the sliding sash can be moved between closed and parallel positions, but the assembly becomes complex and sensitive to manufacturing tolerances
Solution Approach 1:
The locking element is inverted from being fixed to the sliding sash to being fixed to the vertical frame profile. This reverses the control relationship: instead of the sash being actively controlled by elements on its own structure, it is passively guided by elements on the stationary frame, simplifying the sash structure and reducing assembly complexity.
Solution Approach 2:
A control element acts as an intermediary between the locking element on the frame and the sliding sash. The control element translates the curved guide path into actual movement of the sash, mediating the interaction and allowing independent optimization of each component.
2Reliability
If control mechanisms are mounted on both the carriage and the opposite side, then the sliding sash can be properly guided, but precise positioning becomes difficult due to assembly tolerances
Solution Approach 1:
The control mechanism is inverted from being on the moving carriage to being on the stationary frame. By fixing the locking element with curved guide to the frame rather than the sash, the reference frame for control is stationary, eliminating errors from carriage movement and tolerance accumulation.
3Ease of manufacture
If fastening elements are visible from the inner side, then assembly is simple, but the aesthetic appearance is compromised
Solution Approach 1:
The screw groove is oriented at an angle (40°-85°) to the plane of the sliding sash, changing the dimensional orientation of the fastening path. This angular orientation allows the groove to pass through the frame profile in a way that hides fastening elements from the interior view while maintaining assembly accessibility from the exterior.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enables easy assembly and compensation for manufacturing tolerances, reducing noise and ensuring smooth movement between closed and parallel positions while maintaining hidden fastening and enhanced security features.
Implementation Method 1
The locking element comprises at least one elastic stop for the sliding sash when the sliding sash is moved along the track to an end position
Implementation Method 2
the curved guide preferably comprises a groove-shaped section for receiving the control element in the closed position, a ramp along another groove-shaped section for moving the sliding sash into the parallel-stored position or the closed position

AI summary
A sliding door comprises a frame and at least one sliding sash movable along a track, which can be moved between a closed position on the frame and a parallel, resting position for movement along the track. At least one closing element (11) with a curved guide (12) is fixed to a vertical frame profile (60) of the frame. A control element (10), movable by a drive rod (8), can be moved within this guide to move the sliding sash between a closed position and a parallel, resting position. This allows for easy assembly of a unit consisting of the closing element and the control element for locking or closing the sliding sash.
