Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sliding door fittings are not adaptable to different guide profiles or sliding elements of varying thicknesses, requiring multiple fitting variants to be stocked, and cannot be easily converted or retrofitted.
Innovation Solution
A kit that includes a holding device with interchangeable guide elements, such as rotating rollers or sliding elements, and adjustable supports, allowing flexible adaptation to various guide rail geometries and door thicknesses, enabling modular conversion of the sliding door fitting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a guide part is designed as a sliding element adapted to the contour of the guide profile, then the guide quality is improved, but the fitting cannot be converted to different guide profiles or sliding elements of different thicknesses
Solution Approach 1:
The guide part is divided into a sliding element and a separate guide section. The guide section can be removed and replaced with different guide sections adapted to different guide profiles, while the sliding element remains. This segmentation allows conversion between different guide profiles without replacing the entire guide part, resolving the contradiction between guide quality and adaptability.
Solution Approach 2:
The holding device is designed to allow vertical displacement of the guide section relative to the sliding element. This dynamic adjustment capability enables the guide section to adapt to height differences and different guide profiles, maintaining guide quality while providing convertibility to different configurations.
2Adaptability or versatility
If multiple fitting variants are created to accommodate different guide profiles and sliding element thicknesses, then adaptability is improved, but the number of components to be kept in stock increases
Solution Approach 1:
The sliding element is designed as a universal component that can work with different guide sections. The holding device provides a standardized interface for mounting various guide sections. This universality allows a single sliding element to serve multiple functions across different guide profiles, reducing the number of fitting variants needed while maintaining broad compatibility.
Solution Approach 2:
Instead of creating different fitting variants for different parameters (guide profile contours, sliding element thicknesses), the invention allows parameter changes by swapping guide sections while keeping the core sliding element unchanged. This approach reduces complexity by maintaining constant core dimensions while adapting only the guide section geometry.
3Manufacturing precision
If the guide part is designed with fixed geometry, then manufacturing precision is improved, but the fitting cannot be adapted to different sliding door thicknesses
Solution Approach 1:
The holding device enables vertical displacement of the guide section relative to the sliding element, providing dynamic adjustability to accommodate different sliding door thicknesses. The fixed geometry of individual guide sections maintains manufacturing precision, while the dynamic mounting system provides the necessary adaptability.
