Solution Overview

Problem

Existing solutions for sealing the horizontal transition between a plaster-coated facade and a roof or attic cover, particularly with thermal insulation, are labor-intensive and prone to leaks, allowing moisture and rainwater to penetrate the facade structure, causing long-term damage.

Innovation Solution

A connection profile with a base leg for inserting between the component and thermal insulation, featuring a receptacle for a sealing tape held in a compressed state by a removable means, a plastering leg with a drip edge, and a weatherboard forming an acute angle, which simplifies assembly and ensures effective drainage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If joint sealing tapes are used between the plastered facade and the adjacent building component, then sealing is attempted, but the installation is quite complex and requires qualified professionals

Engineering Contradiction:
Improvesealing effectVSAvoidinstallation complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The connection profile is divided into distinct functional segments: a base leg for insertion between component and insulation, a sealing leg with compressed sealing tape, a weather leg for drainage, and a plastering leg for finishing. This segmentation allows each part to perform its specific function independently, simplifying the overall installation process while maintaining reliable sealing.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The connection profile acts as an intermediary element that mediates between the plastered facade and the adjacent building component. It provides a standardized interface that simplifies the connection process and ensures proper sealing and drainage without requiring complex installation procedures or qualified professionals.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If sheet metal profiles are used to form enclosing units around the upper edge of thermal insulation, then sealing is achieved, but the attachment effort is relatively large

Engineering Contradiction:
Improvesealing effectVSAvoidinstallation speed
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The profile material is changed from traditional sheet metal to plastic, which allows for easier manipulation and attachment. The plastic material can be simply pressed into place or attached using standard fasteners, significantly reducing the attachment effort and installation time while maintaining the required sealing functionality through the compressed sealing tape mechanism.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If compressed sealing tapes are used in U-shaped recesses, then sealing is provided, but precise adhesive fastening is required before insulation installation

Engineering Contradiction:
Improvesealing effectVSAvoidinstallation simplicity
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The sealing tape is pre-compressed within the U-shaped recess during manufacturing, creating a ready-to-use sealing element. During installation, the connection profile is simply inserted into the joint between the component and insulation board, and the pre-compressed sealing tape automatically engages to provide the seal, eliminating the need for precise adhesive fastening before insulation installation.

Inventive Principle:
Principle #10Preliminary action

4Reliability

If connection profiles with sealing elements are used, then sealing is attempted, but rainwater and moisture cannot be adequately drained away

Engineering Contradiction:
Improvesealing effectVSAvoidmoisture penetration
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The drainage function is extracted as a separate weather leg that projects from the connection profile and forms an acute angle with the plastering leg. This dedicated drainage element collects and directs rainwater and moisture away from the sealing interface, preventing moisture penetration while maintaining the sealing effect of the compressed sealing tape.

Inventive Principle:
Principle #2Taking out (Extraction)
