Solution Overview

Problem

Existing solar module installations on flat roofs face challenges such as increased difficulty in roof access for maintenance, additional strain on the roof surface, and inadequate protection for electrical supply lines, due to the design of previous support structures.

Innovation Solution

A stable solar module support system featuring an open hollow profile element with a trapezoidal or wavy cross-section, which directs load into the roof structure, provides secure module positioning, and incorporates a holder with a channel-shaped deformation for easy module fixation and cable protection, allowing for safe maintenance and reduced fastening requirements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If solar modules are attached directly to angle profiles on the roof, then the device provides stable support for solar modules, but access to the roof for maintenance becomes considerably more difficult

Engineering Contradiction:
Improvestability of solar module supportVSAvoidaccess to roof for maintenance
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The patent introduces a profile element as an intermediary component between the support structure and the solar module. This profile element creates a spatial separation that maintains structural stability while providing clearance for maintenance personnel to access the roof surface, thus resolving the contradiction between stability and ease of operation

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The invention adds a vertical dimension to the support structure by elevating the solar module mounting position above the roof surface. This dimensional change creates sufficient clearance space below the module for maintenance access while preserving the structural stability through the profile element design

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

2Reliability

If the support structure is designed to carry the load safely, then the device provides reliable support, but additional strain is placed on the roof surface

Engineering Contradiction:
Improvereliability of solar module supportVSAvoidload on roof surface
Core Design Contradiction:
ReliabilityVSForce

Solution Approach 1:

The patent extracts the load-bearing function from the roof surface itself and transfers it to a dedicated support structure. The profile element and support system are designed to carry the solar module load independently, preventing this force from being imposed on the roof surface and maintaining both reliability and reducing stress

Inventive Principle:
Principle #2Taking out (Extraction)

3Ease of manufacture

If the profile element is designed as an open hollow profile with trapezoidal or wavy cross-section, then the device is simple and inexpensive to produce, but additional measures are needed to protect electrical supply lines

Engineering Contradiction:
Improvemanufacturing simplicity and costVSAvoidcable protection requirements
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The patent merges the cable protection function with the existing profile element structure. The open hollow profile is designed to accommodate and protect electrical supply lines within its cavity, combining structural support and cable protection into a single integrated component that remains simple and inexpensive to manufacture

Inventive Principle:
Principle #5Merging (Combining)

4Stability of the object's composition

If holders are provided on the profile element to secure solar modules, then module positioning is stable and secure, but the device complexity increases

Engineering Contradiction:
Improvepositioning stability of solar moduleVSAvoidnumber of holding components
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The patent designs the profile element to serve multiple functions: structural support, module positioning, and securing. The holders are integrated into the profile element design, allowing a single component to perform multiple functions and reduce overall device complexity while maintaining stable module positioning

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