Solution Overview

Problem

The existing solar cell module assembly process is time-consuming and costly due to the need for precise alignment and assembly of fastening members, and it is prone to loosening under external shocks or vibrations, leading to potential damage and reduced power generation efficiency.

Innovation Solution

A solar cell module with a frame having a fixing hole and a first fastening member with an engagement member, which is integrally coupled to the frame using riveting, and a second fastening member connected to the support member, enhancing stability and allowing for easy loosening as needed, using a lock nut configuration to prevent loosening due to external shocks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If fastening members are individually arranged with one at the outer side and one at the inner side of the support structure, then the solar cell module can be fixed to the support structure, but the assembly process becomes time-consuming and costly due to difficulty in assembling the fastening members with each other

Engineering Contradiction:
Improvecoupling stabilityVSAvoidassembly time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent combines the first and second fastening members into a single integrated fastening member that spans both the outer and inner sides of the support structure. This merging eliminates the need to separately assemble two distinct fastening members, significantly reducing assembly time and complexity while maintaining the dual-sided anchoring capability that ensures coupling stability.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The fastening member is segmented into multiple functional portions: a first portion extending to the outer side of the support structure, a second portion extending to the inner side, and a third portion passing through the support structure. This segmentation allows each portion to perform its specific function independently while being part of a unified structure, enabling simplified installation without compromising stability.

Inventive Principle:
Principle #1Segmentation

2Ease of manufacture

If fastening members are individually arranged and assembled, then the solar cell module can be coupled to the support structure, but the fastening members may be easily loosened under external shock or continuous vibration

Engineering Contradiction:
Improvecoupling process simplicityVSAvoidanti-loosening capability
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

By merging the fastening members into a single integrated component that spans both sides of the support structure, the patent creates a more reliable connection. The unified structure distributes mechanical stresses more evenly and prevents the relative movement between separate fastening members that could lead to loosening under vibration or shock loads.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The fastening member is pre-configured with its first portion extending to the outer side and second portion extending to the inner side before installation. This preliminary configuration ensures proper positioning and alignment during installation, reducing the risk of improper assembly that could lead to loosening, while simplifying the manufacturing and installation process.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If a complex fastening system is used to prevent loosening under vibration, then coupling stability improves, but the assembly process becomes more time-consuming and costly

Engineering Contradiction:
Improvecoupling stability under vibrationVSAvoidfastening system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The fastening member is divided into three functional segments (first portion, second portion, and third portion) that work together to provide vibration resistance. This segmentation allows the single component to achieve the stability of a complex multi-part system while maintaining the simplicity of a single-piece design, avoiding the need for multiple separate fastening elements.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The integrated fastening member performs multiple functions simultaneously: it anchors the solar cell module to the support structure, resists loosening under vibration through its multi-portion design, and simplifies the assembly process. This multi-functionality eliminates the need for separate components for each function, reducing overall system complexity while maintaining high reliability.

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