Sliding Door Frame Structure with Adjustable Corner Connector
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing window and sliding door designs face issues with the guide mechanism falling off due to thin materials, unadjustable gaps between frames, and complex assembly processes, leading to reduced permeability and inflexible sliding.
Innovation Solution
A frame structure with a corner connector and roller mechanism that allows for adjustable gaps and a guide mechanism with a sliding assembly to securely attach components, enhancing glass area and simplifying assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the guide mechanism is fixed to the window sash by screws, then the guide mechanism can be attached to the window sash, but the guide mechanism is easy to fall off during sliding because the window sash uses thin-walled material
Solution Approach 1:
The patent introduces a corner connector as an intermediary component that connects adjacent side frames together, distributing the load and providing a more robust attachment structure. The guide mechanism is then fixed to this reinforced corner structure rather than directly to the thin-walled window sash, solving the reliability issue without requiring thicker materials.
2Adaptability or versatility
If the roller is fixed to the window sash by screws, then the roller can be attached to the window sash, but the gap between the window frame and window sash cannot be adjusted
Solution Approach 1:
The patent employs adjustable corner connectors with movable components that allow the gap between the window frame and sash to be dynamically adjusted. The corner connector includes adjustable elements that can be positioned at different locations, enabling flexible gap control while maintaining a relatively simple overall structure.
3Area of stationary object
If the glass mounting slot is located right above the roller, then the window sash structure is simplified, but the frame of the window sash becomes wide and the glass area not embedded in the frame decreases
Solution Approach 1:
The patent repositions the glass mounting slot from a vertical arrangement directly above the roller to a horizontal arrangement alongside the roller assembly. This dimensional reconfiguration allows the glass area to be maximized while the frame width is minimized, as the mounting slot now extends in the horizontal direction rather than increasing the vertical frame height.
4Ease of manufacture
If the corner connector and roller are installed separately, then the components can be individually assembled, but the assembling process of casement and frame becomes complex
Solution Approach 1:
The patent integrates the roller assembly into the corner connector as a unified component. The roller is pre-mounted within the corner connector structure, creating an integrated assembly unit that is installed as a single piece. This merging of components simplifies the overall assembly process and improves installation efficiency while maintaining the ability to manufacture components separately.

AI summary
A frame structure includes a frame body, a corner connector and roller mechanism arranged in a splice of adjacent side frames at a bottom of the frame body, and a guide mechanism clamped to a top of the frame body. A glass positioning slot is disposed on a first side of an inner side wall of a side frame of the frame body. A mounting slot is disposed on a first side of an outer side wall of the side frame of the frame body and used for fixing the guide mechanism or the corner connector and roller mechanism. The glass positioning slot is adjacent to the mounting slot along a lengthwise direction of the first side of the inner side wall. A sliding door is further provided.
