Solution Overview

Problem

All-glass corners made of insulating glass suffer from thermal bridging issues, leading to condensation on the inside, and conventional sealing arrangements compromise their aesthetic appeal and thermal insulation.

Innovation Solution

The design features two insulating glass parts pushed together at an angle with a gas-filled space between them, eliminating thermal bridges and using a tongue-and-groove connection or adhesive strips for sealing, which maintains the all-glass appearance while enhancing thermal insulation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If conventional sealing arrangements with spacer parts are used at the abutting ends of insulating glass units, then thermal insulation is compromised and thermal bridges are created, but the all-glass aesthetic appearance is partially lost

Engineering Contradiction:
Improvethermal insulationVSAvoidall-glass appearance
Core Design Contradiction:
TemperatureVSShape

Solution Approach 1:

The invention extracts and removes the conventional sealing arrangement with spacer parts from the abutting ends of the insulating glass units. By eliminating these thermal bridge components, the patent achieves continuous thermal insulation across the corner joint while maintaining the pure all-glass aesthetic appearance without visible metal or plastic spacers.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The invention merges the sealing function directly into the glass panes themselves through edge treatment and direct bonding at the abutting ends. This integration eliminates the need for separate spacer components, combining the structural, sealing, and aesthetic functions into the glass elements alone, thereby preventing thermal bridges while preserving the all-glass appearance.

Inventive Principle:
Principle #5Merging (Combining)

2Shape

If insulating glass units are pushed together at right angles to form corners, then an all-glass aesthetic is achieved, but thermal bridges are created at the abutting ends causing condensation

Engineering Contradiction:
Improveall-glass corner appearanceVSAvoidcondensation formation
Core Design Contradiction:
ShapeVSObject-affected harmful factors

Solution Approach 1:

The invention converts the potentially harmful thermal bridge effect into a beneficial continuous insulation system. By treating the glass edges and using direct bonding without metal spacers, the patent transforms the corner joint from a thermal weakness into a thermally efficient connection, eliminating condensation risk while maintaining the all-glass aesthetic.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

Solution Approach 2:

The invention changes the thermal parameters at the corner joint by eliminating high thermal conductivity materials (metal spacers) and using low thermal conductivity bonding methods. This parameter change in the joint's thermal properties prevents the formation of thermal bridges and the subsequent condensation that would occur with conventional constructions.

Inventive Principle:

3Ease of manufacture

If asymmetric insulating glass units are used with one unit inside the other, then manufacturing is simplified, but thermal bridges still cannot be compensated for

Engineering Contradiction:

Core Design Contradiction:
Ease of manufactureVSTemperature

Solution Approach 1:

The invention extracts the thermal bridge problem from the asymmetric nesting configuration by removing the conventional sealing arrangements with spacer parts from both the outer and inner insulating glass units. This extraction allows the asymmetric manufacturing advantage to be retained while eliminating the thermal insulation compromise.

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

The corner has two insulation glass parts (2, 4) colliding with each other at an angle under formation of a corner arrangement. Each of the insulation glass parts has two windowpanes (6a, 8a, 6b, 8b), which are connected by distance maintaining parts (10a, 10e) under formation of continuous pane spaces (12a, 12b) filled with gas. The two insulation glass parts collide with each other such that they form continuous pane spaces in a collided area.
