Solution Overview

Problem

Existing fastening devices for wall elements at non-180° angles are bulky, laborious to install, and aesthetically unpleasing, lacking flexibility and ease of disassembly.

Innovation Solution

A fastening device comprising transverse support and closing profiles that integrate with angle profiles, allowing for reduced dimensions, easy installation, and improved aesthetics by eliminating the need for separate coupling means and aesthetically unpleasing locking elements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If traditional fastening devices are used to fit wall elements at non-180° angles, then the wall elements can be constructed, but the fastening device has much larger dimensions and is less aesthetically pleasing

Engineering Contradiction:
Improvedimension of fastening deviceVSAvoidaesthetic appearance
Core Design Contradiction:
Volume of moving objectVSShape

Solution Approach 1:

The patent combines the angle support profile and angle closing profile into a single integrated fastening device unit. The angle support profile includes integrated coupling means that directly connect to the angle closing profile, eliminating the need for separate coupling components. This merging of functions reduces the overall volume and creates a more compact, aesthetically pleasing appearance while maintaining the ability to fit wall elements at non-180° angles.

Inventive Principle:
Principle #5Merging (Combining)

2Ease of operation

If dovetail-shaped connecting elements are attached from the top side or bottom side of profiles, then the wall elements can be fitted, but the installation process is relatively laborious

Engineering Contradiction:
Improveease of installationVSAvoidinstallation time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The patent segments the fastening device into modular components: an angle support profile with integrated coupling means, an angle closing profile, and transverse support and closing profiles. These segmented modules can be independently installed and assembled, allowing for easier installation compared to traditional monolithic fastening devices. The modular segmentation enables step-by-step assembly without requiring complex manipulation of large dovetail-shaped connecting elements from top or bottom sides.

Inventive Principle:
Principle #1Segmentation

3Shape

If profiles extend across the entire height between floor and ceiling, then aesthetic reasons are satisfied, but the top side or bottom side becomes inaccessible for attachment

Engineering Contradiction:
Improveaesthetic appearanceVSAvoidaccessibility for attachment
Core Design Contradiction:
ShapeVSEase of operation

Solution Approach 1:

The patent transitions from attaching components from the top or bottom side (vertical dimension) to attaching components from the side faces (horizontal dimension). The angle support profile and angle closing profile are designed with coupling means that connect to transverse support and closing profiles from the side, allowing profiles to extend across the full height for aesthetics while maintaining accessibility for attachment through side access rather than top/bottom access.

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

4Reliability

If locking elements with openings are used to couple column elements, then the wall elements can be secured, but the openings are not aesthetically pleasing

Engineering Contradiction:
Improvestructural stabilityVSAvoidaesthetic appearance
Core Design Contradiction:
ReliabilityVSShape

Solution Approach 1:

The patent merges the coupling function into the profile structure itself rather than using separate locking elements with openings. The angle support profile includes integrated coupling means that connect directly to the angle closing profile and transverse profiles without requiring separate locking components with visible openings. This integration maintains structural stability while eliminating the aesthetically unpleasing openings, as the connection is achieved through the profile geometry itself.

Inventive Principle:
Principle #5Merging (Combining)
