Solution Overview

Problem

Existing solar module holding devices are inefficient in terms of material usage and assembly, with complex production processes and high material waste, while also lacking in stability and ease of assembly for solar modules that need to be mounted on a rotatable axis to track the sun's position.

Innovation Solution

A solar module holding device with a one-piece sheet metal base body featuring integrally formed hook-shaped holding elements and a design that allows for efficient production with minimal material waste, incorporating a tapering structure for optimal force distribution and stability, along with features like side walls and axle support elements for secure mounting and easy assembly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If solar module holding devices use complex production processes with multiple components, then assembly stability can be improved, but material waste increases and manufacturing complexity increases

Engineering Contradiction:
Improveassembly stabilityVSAvoidmaterial waste
Core Design Contradiction:
ReliabilityVSLoss of substance

Solution Approach 1:

The patent combines multiple separate components (base body, holding elements, mounting elements) into a single integrally molded base body. This merging eliminates the need for separate parts and assembly steps, reducing material waste while maintaining structural stability for solar module mounting.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The integrally molded base body serves multiple functions simultaneously: it provides structural support, contains hook-shaped holding elements for securing modules, includes mounting elements for attachment, and offers a support surface. This multi-functionality reduces the number of separate components needed, decreasing material consumption while ensuring assembly stability.

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

2Strength

If solar module holding devices use traditional multi-component designs, then structural strength can be maintained, but manufacturing time increases and production efficiency decreases

Engineering Contradiction:
Improvestructural strengthVSAvoidmanufacturing efficiency
Core Design Contradiction:
StrengthVSProductivity

Solution Approach 1:

The patent merges multiple components into a single integrally molded base body, eliminating sequential assembly steps and reducing manufacturing time. The integral design maintains structural strength through continuous material flow while enabling faster production through single-step manufacturing processes.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The holding elements and mounting elements are pre-formed as integral parts of the base body during the molding process itself, rather than being added separately afterward. This preliminary formation of all structural features in one step significantly improves manufacturing efficiency while preserving structural integrity.

Inventive Principle:
Principle #10Preliminary action

3Ease of operation

If solar module mounting elements are arranged centrally on the base body, then assembly simplicity can be improved, but stability and force distribution deteriorate

Engineering Contradiction:
Improveassembly simplicityVSAvoidforce distribution
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

The patent employs an asymmetric arrangement where hook-shaped holding elements are positioned offset from the center line toward the side walls of the base body. This asymmetric positioning optimizes force distribution across the structure during solar module mounting, preventing stress concentration at the center while maintaining assembly simplicity through the intuitive hook design.

Inventive Principle:
Principle #4Asymmetry

Solution Approach 2:

The holding elements are strategically positioned at specific locations offset from the center, creating local quality variations in the structure. This localized positioning optimizes the force distribution at critical mounting points while the overall simple integral design maintains ease of assembly.

Inventive Principle:
Principle #3Local quality

4Reliability

If solar module holding devices use extensive material for robust construction, then stability and strength are improved, but material consumption increases and cost increases

Engineering Contradiction:
Improvemounting stabilityVSAvoidmaterial consumption
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The patent combines all functional elements into a single integrally molded base body, eliminating redundant materials that would exist in multi-component designs. This merging achieves mounting stability through optimized structural integration while minimizing total material consumption by removing unnecessary components and connections.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The integral molding process allows for optimized material distribution throughout the base body, concentrating material where structural strength is needed while using minimal material in non-critical areas. This parameter optimization achieves robust mounting stability with reduced overall material consumption compared to traditional multi-component designs.

Inventive Principle:
Principle #35Parameter changes
