Solution Overview

Problem

Insulating glazing with electrical connections faces challenges during transportation and storage due to hanging cables, which can be damaged, leading to replacement of the entire unit and compromising gas tightness.

Innovation Solution

The integration of a circumferential spacer with a desiccant, such as silica gel, and a connector assembly that includes an inner, middle, and outer plug connection, allowing for secure and gas-tight electrical connections within the glazing, eliminating the need for external cables and enhancing mechanical stability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If external cables are used for electrical connections in insulating glazing, then electrical functionality is achieved, but the cables can be damaged during transportation and storage, compromising reliability and gas tightness

Engineering Contradiction:
Improveelectrical connection reliabilityVSAvoidcable damage risk
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent extracts the electrical connection functionality from external cables and relocates it inside the insulating glazing unit. The connector assembly with contact elements is integrated within the sealed cavity, eliminating the need for external cables that extend outside the unit. This internal integration removes the vulnerable external cable portions that are prone to damage during transportation and storage.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The connector assembly is nested within the insulating glazing structure itself. The contact elements are positioned inside the sealed cavity between the panes, with the connector assembly being partially integrated in the spacer. This nesting approach allows the electrical connection system to be contained within the protective envelope of the insulating glazing unit.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Use of energy by moving object

If external cables are used for electrical connections, then power supply is enabled, but cable connectors reduce long-term gas tightness

Engineering Contradiction:
Improvepower supply capabilityVSAvoidgas tightness stability
Core Design Contradiction:
Use of energy by moving objectVSStability of the object's composition

Solution Approach 1:

The patent extracts the electrical connection points from the external perimeter of the insulating glazing and relocates them to the internal cavity. By positioning the contact elements and connector assembly inside the sealed space, the system eliminates the need for penetrations or connections at the external seal interfaces, thereby preserving the integrity of the gas tight sealing system.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The electrical connection system is nested within the sealed cavity of the insulating glazing unit. The connector assembly with its contact elements is contained inside the gas-filled space, allowing power supply functionality while maintaining the external seal integrity. The internal positioning ensures that the gas tightness is not compromised by external cable connections.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Ease of operation

If cables hang out from the insulating glazing, then electrical connection is possible, but the production and storage process becomes more complex and error-prone

Engineering Contradiction:
Improveelectrical connection easeVSAvoidproduction process complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent extracts the vulnerable cable management issue from the system by eliminating external cables entirely. The electrical connection functionality is achieved through internal contact elements that connect to external contacts on the outer surface of the insulating glazing, removing the need for hanging cables that complicate production and storage handling.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The connector assembly is pre-integrated into the insulating glazing unit during manufacturing, with contact elements positioned and secured within the sealed cavity before the unit is completed. This preliminary integration ensures that no additional cable management steps are needed during transportation, storage, or installation, simplifying the overall process chain.

Inventive Principle:
Principle #10Preliminary action
