Composite Glass Door Assembly Without Vertical Supports
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Refrigeration units with transparent glass doors lack structural reinforcement that maintains visibility while ensuring stability, as traditional vertical supports obstruct the view and existing connections are insufficient.
Innovation Solution
A laminated glass pane composed of multiple glass panes connected with a transparent hardened adhesive, reinforced by a strip-like profile of transparent hardened plastic or metal, forming a composite surface that maintains structural integrity without obstructing the view.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If vertical supports or struts are added to reinforce the glass door structure, then structural stability is improved, but visibility into the interior goods compartment is impaired
Solution Approach 1:
The glass door is divided into multiple individual glass panes (at least two) that are connected to each other. This segmentation allows the structure to gain strength through the composite arrangement while maintaining transparency, as each pane remains visually unobstructed and the connections are minimized to essential areas only.
Solution Approach 2:
The invention uses a composite structure combining multiple glass panes with adhesive material and reinforcement elements. The glass panes provide transparency and structural integrity, while the adhesive and reinforcement provide additional bonding strength. This composite approach enables the door to achieve the required mechanical stability without adding opaque vertical supports that would block visibility.
2Stability of the object's composition
If multiple glass panes are connected with adhesive, then structural integrity is improved, but connection strength is insufficient without additional reinforcement
Solution Approach 1:
The invention merges multiple reinforcement approaches by combining adhesive material with additional reinforcement elements (such as profile structures or edge reinforcements). The adhesive provides baseline bonding between glass panes, while the reinforcement elements supplement this connection strength, creating a multi-layered bonding system that addresses both structural integrity and connection strength requirements.
Solution Approach 2:
The connection system uses a composite of adhesive material and reinforcement elements (metal, plastic, or other materials). This composite connection structure provides both the flexibility and bonding capability of adhesive and the structural strength of reinforcement elements, resolving the contradiction between maintaining structural integrity through adhesive while achieving sufficient connection strength through additional reinforcement.

AI summary
The invention relates to a composite pane (73) comprising two glass panes (17), each of which has an inner side (71), an outer side (72) and a plurality of end faces (70) running between the inner side (71) and the outer side (72). , wherein the glass panes (17) are connected in the region of one of their end faces (70) in such a way that the inner sides (71) form a common inner surface (68) and the outer sides (72) form a common outer surface (69). According to the invention, the glass panes (17) are connected at least in sections with the aid of a transparently hardened adhesive (44), the adhesive (44) extending between two opposite end faces (70) of the glass panes (17) and beyond an area of the Inner sides (71) of the glass panes (17) covered, which adjoins the end faces (70) of the glass panes (17) connected to the adhesive (44).
