Insulating Glass Element Concealed Pane Securing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing insulating glass elements for glass facades face challenges in securing the outer pane both aesthetically and mechanically, as current fastening methods either expose the securing components or constrain the pane, compromising safety and aesthetics.
Innovation Solution
The design incorporates a triple glazing system with safety clips that engage between the inner and middle panes and in a groove of the outer pane, allowing for indirect mechanical securing of the outer pane without visible fastening elements, using spacers and separate fastening and securing components to ensure constraint-free and concealed attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If fastening elements are designed to secure the outer pane with a common component, then the attachment to the facade is simplified, but the outer pane cannot be secured without being constrained by the attachment
Solution Approach 1:
The fastening system is divided into two separate functional components: fastening elements for attaching the insulating glass element to the facade, and separate securing clips for securing the outer pane. This segmentation allows each component to perform its specific function independently without compromising the other, resolving the contradiction between simplified attachment and reliable pane security.
Solution Approach 2:
The securing clip acts as an intermediary component that connects the outer pane to the insulating glass element's frame. This intermediary element enables the outer pane to be secured without direct constraint from the facade attachment, allowing the pane to be mechanically secured while maintaining freedom of movement relative to the facade structure.
2Reliability
If fastening elements are designed separately for fastening to the facade and for securing the outer pane, then the outer pane can be secured without constraint, but the securing of the outer pane is visible from the outside
Solution Approach 1:
The securing clips are positioned within the profile structure of the insulating glass element, nested between the visible outer surface and the internal components. This nesting conceals the securing clips from external view while maintaining their functional integrity, allowing the outer pane to be secured reliably without visible fastening elements from the outside.
Solution Approach 2:
The securing clips are strategically positioned in specific locations within the profile structure where they are functionally effective but aesthetically concealed. This local placement allows the system to maintain aesthetic quality at the visible outer surface while providing reliable security at the functional securing locations within the profile.
3Reliability
If securing clips engage directly in the outer pane, then the outer pane is mechanically secured, but forcing the clips can lead to damage to the outer pane
Solution Approach 1:
A groove is预先 formed in the outer pane at the location where the securing clip will engage. This preliminary action creates a prepared receptacle that guides the securing clip into place without forcing, preventing damage to the outer pane while ensuring reliable mechanical engagement for securing the pane.
4Temperature
If the insulating glass element uses triple glazing with spacers creating intermediate spaces, then the structure provides thermal insulation, but the complexity of engaging securing clips in intermediate spaces increases
Solution Approach 1:
The profile structure of the insulating glass element is designed to serve multiple functions: it provides the frame for holding the glass panes, creates the intermediate spaces for thermal insulation with spacers, and simultaneously serves as the mounting structure for both the fastening elements and the securing clips. This multi-functionality reduces the need for additional separate components, simplifying the overall securing mechanism despite the triple glazing complexity.
