Solution Overview

Problem

Window connection profile strips often face issues with tightness at joints between sections and between the end of the profile strip and adjacent components, leading to potential leaks and compromised seals.

Innovation Solution

A system featuring a sealing element with a carrier and sealing body that is clipped or inserted into the window connection profile strip, providing a reliable seal without visible interruption, suitable for both straight and corner areas, using elastic materials like foam plastics.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If window connection profile strips are cut to required lengths, then adaptability to different installation needs is improved, but joints between sections are created which compromise tightness

Engineering Contradiction:
Improveadaptability to different installation needsVSAvoidtightness at joints
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The sealing element is divided into a carrier component and a separate sealing body component. The carrier is installed in the profile strip while the sealing body is positioned in the joint area, allowing independent optimization of each component's function and installation process.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The sealing element acts as an intermediary component between adjacent profile strip sections. It includes a sealing body that specifically addresses the joint area where two sections meet, providing a mediator that ensures tightness despite the presence of joints from cutting operations.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If sealing elements are added to joints, then tightness is improved, but device complexity increases

Engineering Contradiction:
Improvetightness at jointsVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The carrier and sealing body are merged into a single sealing element assembly that can be installed together. The carrier integrates mounting features (such as clipping mechanisms or adhesive surfaces) while the sealing body integrates the sealing function, combining multiple functions into one component system.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The sealing element is designed to be self-contained with all necessary sealing components integrated into a single unit that can be installed as one piece. The carrier and sealing body work together automatically once installed, requiring no additional separate sealing measures or complex assembly procedures.

Inventive Principle:
Principle #25Self-service

3Reliability

If sealing bodies are placed in joint areas, then tightness is improved, but visual appearance deteriorates due to visible sealing components

Engineering Contradiction:
Improvetightness at jointsVSAvoidvisual appearance
Core Design Contradiction:
ReliabilityVSShape

Solution Approach 1:

The sealing function is extracted and concentrated into a dedicated sealing body component that is specifically positioned in the joint area where it is functionally required but visually minimized. The carrier provides structural support while the sealing body provides the sealing action, separating structural and sealing functions.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The sealing body is specifically positioned and dimensioned to provide sealing only in the joint area where it is needed, rather than along the entire length of the profile strip. This localized approach ensures tightness at critical joint points while maintaining a clean visual appearance in visible areas.

Inventive Principle:
Principle #3Local quality

Applied Scientific Principles

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

AI summary

A sealing element (4), designed to seal the joint area (3) between sections 2 of window connection profile strips (1), comprises a sealing body (7) made of elastic material. The sealing body (7) is arranged on a carrier (6) that is mounted on the window connection profile strip (1), for example, clipped into a groove (8) or inserted into a cavity (22). The sealing body (7) is positioned in a recess (12) of at least one window connection profile strip (1) and is not visible from the visible side.
