Glass Disc Assembly for Fire-Resistant Ribbon Windows
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fire protection regulations for yachts and ships require special fire-resistant glazing, which restricts exterior design aesthetics, particularly preventing the use of ribbon windows that are popular among designers and customers.
Innovation Solution
A combined glass pane arrangement featuring exterior glazing without fire protection and interior fire-resistant glazing, where the exterior glazing is designed to meet aesthetic demands while the interior glazing meets fire protection standards, with the two panes connected by flame-retardant interlayers, allowing for a visually uniform and aesthetically pleasing design that also provides wind and water protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fire-resistant glazing with frames is used to meet fire protection regulations, then fire safety is improved, but exterior design aesthetics deteriorate due to visible frames that prevent ribbon windows
Solution Approach 1:
The glazing system is divided into two separate panes: an outer pane for aesthetic purposes and an inner pane for fire protection. This segmentation allows each pane to fulfill its specific function independently, with the outer pane providing the desired ribbon window appearance and the inner pane ensuring fire safety compliance.
Solution Approach 2:
The fire-resistant glazing pane is positioned behind the outer aesthetic pane, creating a nested structure where the inner fire protection pane is embedded within the overall glazing assembly. This nesting allows the fire-resistant frame to be hidden from external view while maintaining its protective function.
2Device complexity
If a single glazing pane is used, then exterior design is simplified, but fire protection requirements cannot be met
Solution Approach 1:
The glazing system is divided into two separate panes: an outer pane for aesthetic purposes and an inner pane for fire protection. This segmentation allows each pane to fulfill its specific function independently, with the outer pane providing the desired ribbon window appearance and the inner pane ensuring fire safety compliance.
3Reliability
If fire-resistant frames are installed to meet regulations, then fire protection is improved, but the visible frames restrict design flexibility and prevent continuous glass fronts
Solution Approach 1:
The fire-resistant glazing pane is positioned behind the outer aesthetic pane, creating a nested structure where the inner fire protection pane is embedded within the overall glazing assembly. This nesting allows the fire-resistant frame to be hidden from external view while maintaining its protective function.
Solution Approach 2:
Different parts of the glazing system have different properties: the outer pane is optimized for aesthetics and transparency, while the inner pane is optimized for fire resistance. This local differentiation allows each component to perform its specific function at the highest level without compromising the other.

AI summary
In order to create a glass pane arrangement (100) that on the one hand meets a fire protection standard and on the other hand meets the designer and customer requirements, a glass pane arrangement (100) is proposed in a watercraft, such as a ship, a cruiser, a yacht, a boat or the like, with a first glazing (10) which is arranged as outer glazing and is designed as glazing in particular without fulfilling fire protection requirements, and with a second glazing (11) which is designed as inner glazing and as fire protection glazing, but which does fulfill fire protection requirements, so that a combined double glazing is present.
