Problem
Conventional solar cell module retaining structures face issues such as misalignment with rafters, increased complexity and cost due to non-standardized frame shapes, and reduced installation efficiency due to complex designs and unnecessary components.
Innovation Solution
A solar cell module retaining structure with slidable holding members that connect to frames with matching cross-sections, allowing for standardized installation and reduced component count, ensuring proper alignment and secure attachment to supporting members like rafters, while minimizing the need for additional covers or complex processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If sway braces are integrally arranged with predetermined pitch, then the frame can be installed on the sheathing slope, but the positions of the sway braces do not match the positions of the rafters, reducing the strength of solar cell module attachment
Solution Approach 1:
The holding member is designed to be slidable along the frame, allowing it to dynamically adjust its position to match the spacing of rafters. This sliding mechanism enables the attachment structure to adapt to varying rafter positions while maintaining standardized frame production, thereby preserving both manufacturing ease and attachment strength.
Solution Approach 2:
The attachment structure is divided into separate components: a standardized frame and a separate slidable holding member. This segmentation allows the frame to be produced with fixed geometry while the holding member independently adjusts to match rafter positions, resolving the conflict between standardized production and adaptive positioning.
2Reliability
If downward pitch side frame and upward pitch side frame have different shapes, then the sway braces can be tied to the sheathing slope, but the number of members increases and processing complexity increases, increasing manufacturing cost
Solution Approach 1:
A single standardized frame design is used for both downward pitch side and upward pitch side, making the frame universal. The slidable holding member serves multiple functions: it provides attachment to rafters, allows positional adjustment, and works with the standardized frame. This universality reduces the number of different frame types needed while maintaining attachment reliability.
Solution Approach 2:
Instead of designing different frame shapes to accommodate different pitch sides, the invention inverts the approach by keeping the frame shape standardized and making the holding member adaptable through sliding. This reverses the traditional design logic and simplifies the overall structure.
3Ease of manufacture
If the installation portion of the mounting base is positioned between the frames, then the mounting base can be installed on the rafter, but the installation area of the solar cell module increases, decreasing the number of possibly installing solar cell modules
Solution Approach 1:
The holding member is extracted from the mounting base and integrated directly with the frame. This separation allows the attachment function to be performed by the holding member while eliminating the need for a separate mounting base that would occupy installation area. The holding member attaches directly to the rafter through the frame, removing the intermediate mounting base structure.
4Device complexity
If the frame and mounting base are open, then the design can be simplified, but additional covers are necessary to improve the design, increasing manufacturing cost
Solution Approach 1:
The holding member integrates the attachment function and the aesthetic cover function into a single component. The slidable holding member with its head portion provides both the mechanical attachment to the rafter and a finished appearance, eliminating the need for separate covers while maintaining design quality and reducing manufacturing complexity.

AI summary
To provide the solar cell module retaining structure, the frame for the solar cell module, and the holding member for the solar cell module, which reduces the number of members relating to the solar cell module retaining structure, standardizes the installation process thereof, and reduces the cost of manufacturing and installing. The solar cell module retaining structure is to fix the solar cell module which comprises the solar cell panel body with the modular glass (6) and the frame (1) to be fixed to the solar panel body to the supporting member (42) via the holding member (2), wherein the frame (1) and the holding member (2) are for the retaining structure of the solar cell module; the holding member (2) can slide relative to the frame (1); the holding member (2) can keep two adjacent frames of two adjacent solar cell modules contacted and restrict one solar cell module from moving in the right angle direction relative to the extending direction of the frame (1); and the holding member (2) is fixed to the supporting member (42) at the lower side of the other solar cell module.
