Solution Overview

Problem

Conventional solar module mounting methods are time-consuming, prone to mechanical stress, and reduce the active surface area available for energy conversion, limiting efficiency and making replacement difficult.

Innovation Solution

A snap-fastening fixing device with reinforcing profiles and supports that allow for rapid and secure mounting of frameless solar modules on structures, utilizing elastic locking mechanisms and U-shaped cross-sections for alignment and immobilization, enabling easy replacement without compromising mechanical strength or active surface area.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If screwing or bolting is used to secure the frame to the mounting structure, then the module is firmly attached to the structure, but the installation time and dismantling time become relatively long

Engineering Contradiction:
Improveattachment reliabilityVSAvoidinstallation time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The fixing device is divided into separate components: a support structure and a snap-on element with a tab. The tab can be independently inserted and snapped into place, allowing for rapid attachment without complex fastening operations. This segmentation enables the attachment mechanism to be simplified from multi-step screwing/bolting to a single snap-on action.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention replaces the traditional mechanical screwing or bolting system with a snap-on mechanism. The tab engages with a recess in the mounting structure through a snapping motion, creating a secure attachment without requiring threads, nuts, or multiple fastening components. This substitution dramatically reduces installation time while maintaining attachment reliability.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Ease of operation

If a metal frame is used to cover the perimeter of the module for mounting, then the module can be secured to the structure, but mechanical stresses are created on the module's periphery that reduce its mechanical strength

Engineering Contradiction:
Improvemounting capabilityVSAvoidmechanical strength
Core Design Contradiction:
Ease of operationVSStrength

Solution Approach 1:

The invention extracts the mounting function from the traditional metal frame that surrounds the entire module perimeter. Instead, a minimal support structure with a tab is used that attaches to a specific location on the module without requiring a continuous frame. This extraction eliminates the frame-induced mechanical stresses while preserving the mounting capability.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The fixing device applies mounting force at a localized point through the tab rather than distributing stress around the entire module perimeter through a frame. The support structure with tab creates a focused attachment point that secures the module without subjecting the peripheral regions to bending or compressive stresses that would weaken the module structure.

Inventive Principle:
Principle #3Local quality

3Ease of operation

If a metal frame is used around the perimeter of the module, then the module can be attached to the structure, but portions of the active surface around the module's periphery are covered that would contribute to energy conversion

Engineering Contradiction:
Improveattachment capabilityVSAvoidactive surface area
Core Design Contradiction:
Ease of operationVSArea of moving object

Solution Approach 1:

The invention removes the perimeter frame that was traditionally used for attachment, extracting only the essential mounting function. The support structure with tab provides attachment capability without requiring a continuous frame that would cover and block the active surface area around the module's periphery, thereby maximizing energy conversion potential.

Inventive Principle:
Principle #2Taking out (Extraction)

4Reliability

If screwing or bolting is used to secure the frame, then the module is firmly attached to the structure, but the dismantling time becomes relatively long in case of module failure

Engineering Contradiction:
Improveattachment reliabilityVSAvoiddismantling ease
Core Design Contradiction:
ReliabilityVSEase of repair

Solution Approach 1:

The fixing device is segmented into a support structure and a removable tab element. The tab can be independently detached from the mounting structure by simply pulling or releasing the snap-on connection, allowing for rapid module replacement without the need to undo multiple screws or bolts. This segmentation enables easy dismantling while maintaining secure attachment during operation.

Inventive Principle:
Principle #1Segmentation
