Solution Overview

Problem

Existing facade cladding substructures require extensive assembly work due to numerous screw connections and height adjustments, especially for large areas, and are cumbersome to install, especially when the substructure is uneven.

Innovation Solution

A substructure with a holding part that can be fixed in different positions on a wall section using a wedge-shaped locking element, which eliminates the need for complex screw connections by providing a clamping or form-fitting fixation, allowing for easy alignment and installation of cladding elements without tools.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If screw connections are used to fix fasteners to cladding elements and substructure, then reliable connection is achieved, but assembly work and time increase considerably

Engineering Contradiction:
Improveconnection reliabilityVSAvoidassembly speed
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The invention extracts the fastening function from the cladding element and relocates it to the substructure. The substructure now provides the connection function through its retaining element and locking mechanism, while the cladding element simply rests on the retaining element. This separation eliminates the need for screw connections to the cladding element, significantly reducing assembly work while maintaining connection reliability through the substructure's locking mechanism.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The retaining element acts as an intermediary between the substructure and the cladding element. It provides a bearing surface for the cladding element and a interface for the locking mechanism, enabling reliable connection without requiring direct screw fixation to the cladding element itself.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Manufacturing precision

If multiple screw connections are required for leveling and securing fasteners, then precise alignment is achieved, but assembly complexity and time increase

Engineering Contradiction:
Improvealignment precisionVSAvoidassembly complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The substructure is pre-assembled with the retaining element and locking mechanism before installation. This preliminary preparation allows for quick alignment and securing during assembly, eliminating the need for complex on-site leveling operations with multiple screw connections.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The locking mechanism is designed to automatically secure the retaining element to the support structure when the locking element is actuated. This self-securing feature reduces the need for manual leveling and multiple adjustment operations, simplifying the assembly process while maintaining alignment precision.

Inventive Principle:
Principle #25Self-service
