Fitting System Frame Element for Modular Functional Units
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The production and assembly of modular functional units for building openings, such as windows or doors, are complicated by the need for precise installation and provision of recesses, especially for larger sets, which increases manufacturing effort and complexity.
Innovation Solution
A frame element with a central opening and a surrounding frame body that serves as a fastening section and receiving space for modular functional units, allowing for easier attachment and accommodation of multiple units, and can be pre-assembled with the frame or sash, simplifying the manufacturing and assembly process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If modular functional units are attached directly to the frame or sash at predetermined positions, then the functional units can be installed, but the manufacturing effort and complexity increase significantly
Solution Approach 1:
A frame element is introduced as an intermediary component between the frame/sash and the modular functional units. This frame element includes a receiving space that accommodates the functional units and fastening sections that enable attachment to the frame or sash. This intermediary structure simplifies the overall manufacturing process by providing a standardized interface for installing multiple functional units without requiring complex predetermined positioning in the frame or sash itself.
2Ease of operation
If recesses are provided in the frame or sash profile to accommodate modular functional units, then the functional units can be installed, but the manufacturing process is complicated
Solution Approach 1:
The frame element is segmented into distinct functional sections: fastening sections for attachment to the frame or sash, a receiving space for accommodating modular functional units, and optional cable duct sections. This segmentation allows the frame element to be manufactured as a separate, standardized component that simplifies the overall manufacturing process, as the complex receiving space geometry is isolated to this single component rather than requiring modifications to the frame or sash profiles.
3Adaptability or versatility
If multiple modular functional units are assembled in a variety of arrangements, then the fitting system becomes versatile, but the assembly process becomes more complex
Solution Approach 1:
The frame element is designed with universal fastening sections and a standardized receiving space that can accommodate multiple different types of modular functional units in various arrangements. The receiving space is configured to accept functional units with different orientations and positions, enabling versatility without requiring complex assembly procedures. The standardized interface allows different functional units to be interchangeably installed in the same frame element.

AI summary
A fitting system for a structural element which has a frame and a wing which is movable relative to the frame comprises at least one modular functional unit which comprises an electric drive and is designed, when in the installed state, to move the wing between at least two different functional states by means of the electric drive. The fitting system also comprises a frame element which has a central opening and a frame body running around the central opening. The frame body has a fastening section for fastening the frame element to the frame or to the wing and is designed such that it defines a holding space for accommodating the at least one modular functional unit, in particular when in the fastened state.
