Solution Overview

Problem

Existing mounting systems for framed photovoltaic modules are structurally complex, require many components, and are not universally adaptable to different module sizes and roof types, necessitating specialized training and potentially damaging existing roof coverings.

Innovation Solution

A simplified mounting system using clip-shaped coupling and locking elements, along with profiles, that can be pre-assembled on modules for easy installation on various inclined surfaces without requiring extensive substructure adjustments, allowing for secure and flexible attachment of photovoltaic modules.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If known mounting systems are used, then structural stability is achieved, but device complexity increases due to numerous components

Engineering Contradiction:
Improvestructural stabilityVSAvoiddevice complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The patent combines multiple separate components (coupling element, locking element, and profile) into an integrated mounting system where the coupling element and locking element work together as a unified attachment mechanism. This merging reduces the number of separate parts while maintaining structural stability through the coordinated action of the clamping coupling element and the locking element with positioning section.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The mounting system is designed with universal applicability through the profile that can accommodate different module sizes and roof types. The coupling element with its clamping design and the locking element with positioning section create a multi-functional system that can be adapted to various installation conditions without requiring specialized components for each module type.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Stability of the object's composition

If known mounting systems are used, then mounting stability is achieved, but quantity of components increases

Engineering Contradiction:
Improvemounting stabilityVSAvoidquantity of components
Core Design Contradiction:
Stability of the object's compositionVSQuantity of substance

Solution Approach 1:

The patent merges the coupling and locking functions into a coordinated system with fewer components. The coupling element encompasses the frame element while the locking element provides securing, replacing the need for multiple separate fastening components in traditional systems.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The system segments the mounting function into three key components: the profile for structural support, the coupling element for frame attachment, and the locking element for securing. This segmentation allows each component to perform its specific function efficiently while reducing the total quantity of components compared to integrated multi-component systems.

Inventive Principle:
Principle #1Segmentation

3Stability of the object's composition

If known mounting systems are used, then structural stability is achieved, but adaptability to different module types decreases

Engineering Contradiction:
Improvestructural stabilityVSAvoidadaptability to module types
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The profile and coupling element are designed with universal characteristics that allow them to work with framed photovoltaic modules of various dimensions and designs. The clamping coupling element can accommodate different frame sizes, and the locking element with its positioning section can adapt to different installation conditions, providing both structural stability and versatility.

Inventive Principle:
Principle #6Universality (Multi-functionality)

4Reliability

If known mounting systems are used, then mounting security is achieved, but ease of operation decreases due to installation complexity

Engineering Contradiction:
Improvemounting securityVSAvoidease of installation
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The coupling element is designed to be pre-assembled with the profile before module installation. This preliminary assembly simplifies the installation process by reducing the number of steps required during mounting, while the locking element ensures secure attachment once installed.

Inventive Principle:
Principle #10Preliminary action

5Stability of the object's composition

If known mounting systems are used, then structural stability is achieved, but loss of time increases due to time-consuming installation

Engineering Contradiction:
Improvestructural stabilityVSAvoidinstallation time
Core Design Contradiction:
Stability of the object's compositionVSLoss of time

Solution Approach 1:

The profile and coupling element are pre-assembled before module installation, which significantly reduces on-site installation time. The locking element is designed for quick engagement, allowing rapid securing of modules while maintaining structural stability.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The segmented design with distinct profile, coupling element, and locking element allows for efficient assembly sequences that reduce installation time while ensuring each component is properly secured for structural stability.

Inventive Principle:
Principle #1Segmentation

6Stability of the object's composition

If known mounting systems are used, then mounting stability is achieved, but object-generated harmful factors increase due to damage to roof covering

Engineering Contradiction:
Improvemounting stabilityVSAvoiddamage to roof covering
Core Design Contradiction:
Stability of the object's compositionVSObject-generated harmful factors

Solution Approach 1:

The profile acts as an intermediary between the mounting system and the roof structure, distributing loads and preventing direct contact that could damage the roof covering. The coupling element with its clamping design provides secure attachment without requiring invasive modifications to the existing roof.

Inventive Principle:
Principle #24Intermediary (Mediator)
