Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shading system fastening systems for building openings, such as windows or doors, face challenges in reliably securing operating profiles using magnetic forces, leading to potential light gaps and complexity in assembly and part variety.
Innovation Solution
A fastening system featuring two operating profiles with magnetic elements, where one magnetic element is attached to the operating profile independently of the slider, allowing for decoupled assembly and use of standard components across different profiles, ensuring magnetic holding force and reduced part variety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the magnetic element is integrated into the slider, then the assembly is simplified, but the magnetic holding force becomes unreliable and light gaps occur
Solution Approach 1:
The magnetic element is separated from the slider into an independent component attached to the operating profile. This segmentation allows the magnetic element to be positioned optimally for reliable magnetic coupling with the holder, while the slider maintains its function for guiding tension cords. The independent attachment ensures the magnetic element cannot shift position, eliminating light gaps while keeping the overall assembly straightforward.
2Adaptability or versatility
If different slider variants are used for different profile cross-sections, then adaptability is improved, but part variety and complexity increase
Solution Approach 1:
The magnetic element is designed as a universal component that can be attached to operating profiles with different cross-sections. By separating the magnetic element from the slider-specific geometry, the same magnetic element design can serve multiple profile types, reducing the number of unique parts needed while maintaining adaptability across different window and door applications.
3Reliability
If the magnetic element is independently attached to the operating profile, then magnetic holding reliability is improved, but assembly steps increase
Solution Approach 1:
The magnetic element is pre-attached to the operating profile during manufacturing, creating a ready-to-install assembly. This preliminary action ensures the magnetic element is in its correct position and orientation before the customer receives the product, eliminating the need for complex field assembly steps while maintaining reliable magnetic coupling with the holder.

Function Achieved in This Case
The system provides reliable magnetic mounting of operating profiles, eliminates light gaps, simplifies assembly, and reduces part variety by using standard components, enhancing stability and ease of use.
Implementation Method 1
The two magnetic elements are positioned such that, when installed and the operating profile is in its end position, they face each other, thus magnetically holding the operating profile in its end position.
