Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional solar module frames are heavy, inefficient in heat dissipation, and prone to overheating, leading to reduced power generation efficiency and shorter service life due to their rigid structure and material composition.
Innovation Solution
A lightweight solar module frame with a composite structure, featuring segments and connection components made of different materials, including a single or double-wall structure, and incorporating openings for improved heat dissipation and mechanical strength, while maintaining weight-bearing capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a conventional solar module frame is formed by four integrally formed metal borders, then the frame has high weight bearing capacity and pressure resisting capability, but the frame becomes heavy and inconvenient to deliver, install, and repair
Solution Approach 1:
The frame is divided into multiple segments including first and second borders, first and second connection components, allowing the structure to be assembled from separate parts rather than being integrally formed, which reduces overall weight while maintaining structural integrity
Solution Approach 2:
The frame uses composite construction with borders made of different materials than connection components, optimizing the balance between weight and mechanical strength by selecting materials with appropriate strength-to-weight ratios for different functional requirements
2Ease of operation
If the solar module is disposed close to the ground for array formation, then the installation is simplified, but heat energy at the bottom cannot be effectively dissipated causing overheating and reduced conversion efficiency
Solution Approach 1:
The connection components incorporate openings that create a porous or perforated structure, enabling air flow through the frame to facilitate heat dissipation from the solar module while maintaining the structural framework
Solution Approach 2:
The connection components serve multiple functions: providing structural support to maintain frame geometry, enabling assembly of border segments, and facilitating heat dissipation through openings, thereby addressing both mechanical and thermal requirements
3Use of energy by moving object
If conventional photoelectric conversion is used, then the solar module can convert light energy into electric power, but most light energy is converted into heat energy resulting in low conversion efficiency
Solution Approach 1:
The openings in the connection components convert the harmful heat energy that would otherwise accumulate in the module into beneficial air flow, allowing heat to be carried away by convection currents, thereby turning the heat problem into a solution
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively reduces the frame's weight, enhances heat dissipation, and improves power generation efficiency while maintaining mechanical strength and reducing manufacturing costs.
Implementation Method 1
An opening may further be provided on the connection component, so that air at the back of the solar module can communicate with ambient air through the opening, thereby solving the heat dissipation problem

AI summary
A solar module frame includes two first borders and two second borders. At least one first border includes a first segment and a second segment, where one end of the first segment is connected to one end of the second border, and one end of the second segment is connected to one end of the other second border. The solar module frame includes at least one connection component. One end of the connection component is connected to the other end of the first segment, and the other end of the connection component is connected to the other end of the second segment. Each of the first segment, the second segment, and the connection component includes an external wall, a support wall, a first clamping wall, and a second clamping wall. Each of the first segment and the second segment includes an internal wall.
