Double Hinge Seal for Mullion Transom Drainage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mullion-transom drainage systems face challenges in ensuring appropriate transitions and mobility of sealing webs at connection areas, leading to inefficiencies in drainage system performance.
Innovation Solution
A seal with a double joint connection system allows the sealing web to perform compensating movements, enabling overlapping and adjustable drainage levels by using U-shaped vertical sections and separable sealing bodies for mullions and transoms, facilitating easier assembly and cost savings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the sealing web is made immobile in the joint area, then the structure is simplified, but the drainage system cannot perform compensating movements and transitions are problematic
Solution Approach 1:
The sealing web is designed with double joint connections that enable it to perform compensating movements dynamically. The double joint at each end of the sealing web allows angular adjustment and movement compensation, transforming the sealing web from a static to a dynamic component that can adapt to structural movements while maintaining sealing functionality.
2Reliability
If separate seal designs are used for mullions and transoms, then each can be optimized, but production and storage costs increase
Solution Approach 1:
A universal seal design is created that can be used for both mullions and transoms. The seal incorporates a double joint system with separable sealing bodies that can be configured differently depending on the application. By removing or retaining specific sealing bodies, the same basic seal design adapts to different structural requirements, eliminating the need for separate optimized designs for mullions and transoms.
3Adaptability or versatility
If the sealing web is made adjustable, then drainage level transitions are improved, but the device complexity increases
Solution Approach 1:
The sealing web is segmented into multiple functional parts with double joint connections at each end. Each double joint consists of two hinge joints with an intermediate piece, allowing independent adjustment. This segmentation enables the sealing web to be divided into adjustable segments that can move relative to each other, providing drainage level adjustability while keeping each individual joint mechanism relatively simple.
