Curtain Wall Glazing Bead Rotational Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing curtain wall systems require installation from the outside, which is complex, dangerous, and difficult to secure panels properly due to challenges with applying glazing beads.
Innovation Solution
A curtain wall system where glazing beads are attached through a guided rotational movement using positioning aids, allowing for easy and safe installation from the inside and ensuring proper alignment and security of panels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If glazing beads are attached by hooking together with seals in an inner profile perpendicular to the facade plane, then panels can be secured to mullion and transom profiles, but the installation becomes complex and difficult
Solution Approach 1:
The patent inverts the traditional installation sequence by first attaching the panel to the outer profile from the outside, then securing the glazing bead to the inner profile from the inside. This reversal simplifies the installation process by allowing each component to be attached independently from its respective side, eliminating the need for complex perpendicular hooking operations.
Solution Approach 2:
The curtain wall system is divided into independent components that can be assembled separately: the outer profile with panel attached forms one segment, while the inner profile with glazing bead forms another segment. These segments are then connected through the mullion and transom profiles, allowing for simplified, independent installation of each segment from different sides of the facade.
2Reliability
If installation is performed from the outside using traditional methods, then panels can be secured with outer profiles, but the process becomes dangerous and requires scaffolding
Solution Approach 1:
The patent enables installation from the inside by inverting the traditional outside-in approach. The panel is first attached to the outer profile from the outside (which can be done safely), then the glazing bead is attached to the inner profile from the inside using floors for support. This eliminates the need for dangerous outside installation at height.
Solution Approach 2:
The mullion and transom profiles serve as intermediary elements that connect the outer and inner profiles. These intermediaries allow the panel securing function to be distributed across multiple components, enabling safe inside installation while maintaining reliable outside fixation.
3Ease of operation
If glazing beads are forced into place with rotation from the inside, then panels can be installed from the inside, but misalignment and damage risk increase
Solution Approach 1:
The patent applies preliminary action by providing positioning aids on the inner profile that guide the glazing bead into correct alignment before final attachment. This pre-positioning ensures proper alignment is achieved before the glazing bead is fully secured, preventing misalignment issues that would otherwise require forceful rotation.
Solution Approach 2:
Positioning aids act as intermediary elements between the inner profile and the glazing bead. These aids facilitate the connection process by providing guidance and alignment, eliminating the need for forceful rotation and reducing the risk of damage during installation from the inside.
