Door Leaf Profile Assembly with Removable Fixing Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wing designs for doors and windows are complex to assemble and space-consuming due to the need for intricate fixing devices and profile sections, which limits their ease of manufacture and installation.
Innovation Solution
A fixing device that can be removed after gluing the profile sections to the panes, eliminating the need for complex connections and allowing for space-saving design, with adjustable fixing elements that serve as assembly gauges and can be clamped or screwed onto the profile sections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a fixing device with corner brackets or threaded sleeves is used to connect profile sections, then the profile sections can be assembled into a frame, but the fixing device takes up space in the profile sections and increases assembly complexity
Solution Approach 1:
The invention extracts the fastening function from separate corner brackets or threaded sleeves and integrates it directly into the profile sections. The profile sections are provided with fastening elements (such as recesses, grooves, or integrated fastening features) that allow direct connection without external fixing devices, thereby eliminating the space occupation and assembly complexity associated with separate fixing devices.
Solution Approach 2:
The invention merges the structural function of the profile sections with the fastening function by integrating fastening elements directly into the profile sections. This combination eliminates the need for separate corner brackets or threaded sleeves, simplifying the overall structure and reducing the number of components required for assembly.
2Ease of manufacture
If threaded sleeves are integrated into profile sections for fastening, then connection is achieved, but the threaded sleeves take up installation space that cannot be used for other purposes
Solution Approach 1:
The invention extracts the fastening function from bulky threaded sleeves and implements it through minimal fastening elements integrated into the profile sections. These fastening elements occupy significantly less space than traditional threaded sleeves, preserving installation space for other purposes such as fitting attachments or structural reinforcement.
Solution Approach 2:
The invention applies fastening features only at the specific locations where connection is needed, rather than incorporating large threaded sleeves that occupy extensive space. The fastening elements are designed to be compact and localized, maintaining the structural integrity and aesthetic appearance while providing sufficient fastening capability.
3Stability of the object's composition
If profile sections are connected using corner brackets with screws, then the frame structure is formed, but the assembly process becomes time-consuming and complex
Solution Approach 1:
The invention incorporates pre-designed fastening elements directly into the profile sections during manufacturing, eliminating the need for complex assembly operations involving corner brackets and multiple screws. The profile sections are prepared in advance with integrated fastening features that enable quick and straightforward connection, significantly improving assembly speed while maintaining structural stability.
Solution Approach 2:
The profile sections are designed to be self-fastening through integrated fastening elements, eliminating the need for separate corner brackets and complex screwing operations. The fastening elements are built into the profile sections themselves, allowing the sections to connect directly to each other in a simple and efficient manner, thereby increasing productivity without compromising structural integrity.

AI summary
A leaf for a door or window with two separate parallel panels is disclosed. The panels are retained around the edge by a support profile forming a support frame essentially lying between the panels and connecting the same. The support profile comprises an upper horizontal profile section, two vertical profile sections and a lower horizontal profile section, whereby the profile sections are connected to the panels by means of a glued joint. A fixing device is provided by means of which the profile sections are arranged to give a frame before the gluing to the panels. The fixing device is embodied to be removable such that after gluing said profile sections to the panels, the profile sections are held together by means of the panels.
