Solution Overview

Problem

Existing supporting structures for insulating glazing, such as those used in glass roofs and facades, face challenges in maintaining longevity due to inadequate drainage of moisture, including rainwater and condensate, which can lead to structural issues.

Innovation Solution

A support structure design featuring parallel posts and a transom with fluid channels that utilize wind-induced pressure differences to facilitate drainage, where the inflow and outflow openings on adjacent posts are of different sizes, ensuring effective ventilation and pressure equalization across the system.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If controlled drainage is implemented in the mullion-transom supporting structure, then moisture drainage capability is improved, but drainage effectiveness deteriorates because condensate and rainwater cannot be sufficiently drained

Engineering Contradiction:
Improvemoisture drainage capabilityVSAvoiddrainage effectiveness
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The patent introduces dynamic pressure equalization channels that allow the supporting structure to adapt to varying moisture conditions. The channels enable pressure equalization between different cavities, allowing the system to dynamically respond to rainwater infiltration and condensate accumulation, thereby achieving effective drainage without compromising structural integrity

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The pressure equalization channels serve as intermediary pathways connecting different cavities in the supporting structure. These channels mediate the moisture management by allowing pressure equalization and controlled moisture transfer between cavities, enabling effective drainage while maintaining the airtight seal of the insulating glazing

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of manufacture

If the edge bond of glass panes is exposed to moisture, then manufacturing simplicity is improved, but service life deteriorates due to moisture penetration and condensate accumulation

Engineering Contradiction:
Improveedge bond exposureVSAvoidservice life of insulating glazing
Core Design Contradiction:
Ease of manufactureVSDuration of action of stationary object

Solution Approach 1:

The patent extracts the moisture management function from the edge seal area by introducing separate pressure equalization channels. This allows the edge bond to remain exposed and simple for manufacturing while the extracted moisture drainage function is handled by the dedicated channels, preventing moisture damage and extending service life

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The pressure equalization channels act as intermediary structures that protect the edge bond from moisture damage. By providing an alternative pathway for moisture management, these channels mediate between the exposed edge bond and the internal cavity, preventing moisture accumulation at the vulnerable edge seal while maintaining manufacturing simplicity

Inventive Principle:
Principle #24Intermediary (Mediator)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

This design enhances the longevity of insulating glazing by ensuring controlled drainage and ventilation, preventing moisture accumulation and reducing the risk of structural damage from water ingress.

Implementation Method 1

Under the influence of the wind, a pressure difference is created between the fluid channels on adjacent posts

Methodology Applied
Scientific EffectPressure difference: Pressure Gradient

Implementation Method 2

Such a support structure uses wind currents that can penetrate into the area between adjacent insulating glazing on the mullions

Methodology Applied
Scientific EffectWind: Wind

Implementation Method 3

A pressure equalization takes place via the fluid channel on the transom, which connects the adjacent fluid channels on the post, thereby ensuring a flow through the fluid channel on the transom

Methodology Applied
Scientific EffectPressure equalization: Pascal's Law
