Solution Overview

Problem

Existing profile rails for cladding elements struggle with larger tolerances in masonry straightness, leading to collisions with uneven corners, which necessitate reworking the masonry to prevent collisions and ensure proper attachment.

Innovation Solution

A profile rail design with a connecting section that extends parallel to the rear side, creating a triangular or rectangular free space for plaster and filler application, allowing for secure attachment without reworking the masonry, and featuring a fastening section for stable connection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a conventional profile rail with connection fabric or connection profile is used, then reliable hold between profile rail and plaster is achieved, but the connection fabric collides with unevenness in masonry corners requiring reworking

Engineering Contradiction:
Improvehold between profile rail and plasterVSAvoidmasonry reworking requirement
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The profile rail is divided into distinct functional sections: a fastening section for securing the rail, a connecting section that extends parallel to the rear side instead of perpendicular, and visible side/end face profile sections. This segmentation allows the connecting section to run along the rear side, creating clearance from masonry corners and eliminating the need for connection fabric that would collide with unevenness.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The connecting section is repositioned from a perpendicular orientation (extending outward from the front) to a parallel orientation (running along the rear side). This dimensional repositioning moves the connecting section away from the problematic interface with masonry corners, allowing plaster to be applied without collision while maintaining reliable connection.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Reliability

If profile rail extends perpendicular to front side with connection fabric, then connection to plaster is achieved, but collision with masonry corner unevenness prevents direct application

Engineering Contradiction:
Improveconnection to plasterVSAvoidmasonry straightness tolerance
Core Design Contradiction:
ReliabilityVSManufacturing precision

Solution Approach 1:

The profile rail is segmented into a fastening section and a connecting section positioned at different locations. The connecting section runs parallel to the rear side, creating spatial separation from the front-facing masonry corners. This segmentation allows the system to maintain reliable plaster connection while accommodating larger tolerances in masonry straightness without collision.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The parallel extending connecting section acts as an intermediary element that provides the necessary connection function while physically distancing the connection point from the problematic masonry corner interface. This intermediary positioning allows plaster to be applied directly without requiring high precision in masonry straightness.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If connection section extends perpendicular from front side, then connection function is provided, but plastering is not possible and appearance degrades

Engineering Contradiction:
Improveconnection functionVSAvoidplastering capability
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The profile rail is segmented into distinct functional zones: the fastening section handles secure attachment, while the connecting section running parallel to the rear side provides plaster connection capability. This segmentation allows each section to perform its function optimally - the connecting section can be plastered over while maintaining its connection function, and the visible sections maintain clean appearance.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The connecting section is repositioned to run parallel to the rear side rather than extending perpendicular from the front. This dimensional change allows the connecting section to be located in a region that can be properly plastered and finished, eliminating the appearance degradation problem while maintaining the connection function.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
