Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sliding windows face challenges with increased glass panel weights due to larger dimensions and higher thermal insulation requirements, leading to weakened profiles and inefficient force transmission to rollers, which can result in premature failure and deformation.
Innovation Solution
The implementation of glass supports with feed-through sections that directly transmit the panel's weight vertically to roller cassettes through the thermal insulator, bypassing the half-shells, ensuring efficient weight distribution and maintaining thermal insulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the dimensions of glass panels and thermal insulator are increased to meet higher thermal insulation requirements, then thermal insulation performance is improved, but the weight of glass panels increases and the profiles are weakened
Solution Approach 1:
The support function is segmented between the thermal insulator (which maintains thermal insulation) and the glass support with feed-through section (which bears the weight). This allows the thermal insulator to focus on insulation while the specialized glass support handles load transmission, resolving the contradiction between insulation performance and weight bearing capacity.
Solution Approach 2:
The glass support with feed-through section acts as an intermediary element between the heavy glass panel and the roller cassettes. It transmits the weight vertically through the thermal insulator to the rollers, allowing the thermal insulator to maintain its insulation function while the intermediary structure handles the mechanical load.
2Temperature
If the dimensions of the thermal insulator are increased to meet higher thermal insulation requirements, then thermal insulation performance is improved, but the strength of the profile is reduced
Solution Approach 1:
The structural function is segmented from the thermal insulator to the glass support with feed-through section. The thermal insulator can be made larger for better insulation without compromising profile strength, as the load-bearing function is performed by the separate glass support structure that transmits forces directly to the rollers.
Solution Approach 2:
The glass support with feed-through section serves as a mediator that allows the thermal insulator to be optimized for insulation dimensions while the intermediary structure handles mechanical strength requirements by providing direct vertical load paths to the rollers.
3Device complexity
If the weight of the glass panel is transmitted to the rollers via the half-shells, then the structure is simple, but the impact on the leaf increases and deformation may occur
Solution Approach 1:
The weight transmission function is extracted from the half-shells and assigned to the glass support with feed-through section. This removes the harmful load impact from the leaf frame while maintaining the simple overall structure, as the feed-through section provides a direct vertical path from panel to rollers.
Solution Approach 2:
The glass support with feed-through section acts as an intermediary that provides a dedicated load transmission path, preventing the half-shells and leaf frame from bearing the full weight impact. This intermediary structure protects the leaf frame from deformation while maintaining structural simplicity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design effectively supports heavier glass panels by distributing weight directly to rollers, reducing stress on the frame and insulator, while preserving thermal insulation and preventing frame deformation.
Implementation Method 1
the at least one glass support comprises a feed-through section for transmitting the weight of the panel or a part thereof to at least one concerned roller cassette and that this feed-through section extends through a bottom leaf profile up to a roller cassette
Implementation Method 2
a slideable leaf in a fixed frame which by means of one or more roller blocks is movably supported in the fixed frame. In particular the invention relates to a sliding window or sliding door with a frame that is composed of profiles each comprising two half-shells, which are thermally separated by means of an intermediate thermal insulator, whereby the thermal insulator also connects the two half-shells with each other
