In-wall Sliding Door Frame with Rotating Movable Section
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing in-wall frames for sliding doors are limited in their ability to adjust the breadth of the opening compartment without requiring a corresponding expansion of the frame and casing, which is costly and impractical in confined spaces.
Innovation Solution
An in-wall frame design featuring a movable first frame with a pivoted configuration, supported by a self-supporting second frame, allowing the breadth of the opening to be adjusted by rotating the second frame relative to the first, using adjustable wheels and a temporary locking mechanism to support the door's weight and facilitate sliding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the in-wall frame is designed with a fixed containment casing to support the sliding door, then the door can slide smoothly within a defined compartment, but the breadth of the opening compartment cannot be adjusted without increasing the frame dimensions and manufacturing costs
Solution Approach 1:
The in-wall frame is divided into a fixed second frame and a movable first frame that can be rotated relative to each other. The movable first frame contains the sliding door, while the fixed second frame provides structural support. This segmentation allows the opening breadth to be adjusted by rotating the movable frame without requiring the entire containment casing to be redesigned or enlarged.
Solution Approach 2:
The first frame is designed to be rotatable relative to the second frame, transforming the static frame structure into a dynamic one. This rotational capability allows the opening compartment breadth to be adjusted between different positions, enabling adaptability while maintaining a compact overall frame structure.
2Adaptability or versatility
If the in-wall frame dimensions are increased to allow for a wider opening compartment, then the opening breadth can be increased, but the manufacturing costs increase and the frame becomes more difficult to install in confined spaces
Solution Approach 1:
By dividing the frame into movable and fixed portions, the invention allows the opening breadth to be changed through rotation rather than by increasing the overall frame dimensions. This keeps the manufacturing costs and installation requirements comparable to standard frame sizes.
Solution Approach 2:
The invention introduces rotation as an additional degree of freedom to adjust the opening breadth. Instead of increasing the linear dimensions of the frame to achieve a wider opening, the movable first frame is rotated within the confines of the fixed second frame, effectively using angular movement to achieve dimensional adjustment.
3Adaptability or versatility
If a movable first frame is introduced to allow rotation and adjustment of the opening, then the adaptability of the frame is improved, but the structural complexity and potential instability of the frame composition increase
Solution Approach 1:
The movable first frame is designed to be rotatable relative to the fixed second frame, allowing dynamic adjustment of the opening breadth. The rotation mechanism includes positioning means that can lock the movable frame at different angular positions, providing stability when adjusted while maintaining the ability to change configuration when needed.
