Solution Overview
Problem
Existing solar cell laminates face challenges in withstanding high surface loads, ease of mounting, and transportation due to inadequate framing solutions.
Innovation Solution
A frame profile with a laminate clamping section and a profile section featuring undercut sides, allowing for secure clamping and form-fit engagement with support rails, enhancing mechanical stability and ease of installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional framing solutions are used for solar cell laminates, then the structure provides basic protection, but it cannot withstand high surface loadings and is difficult to mount
Solution Approach 1:
The frame profile is divided into functionally distinct sections: a laminate clamping section with parallel clamping feet for securing the solar cell laminate, and a profile section with a portion formed by sides having an undercut for form-fit engagement with support rails. This segmentation allows each section to be optimized for its specific function, enabling the frame to withstand high loads while maintaining ease of mounting.
Solution Approach 2:
The profile section incorporates an asymmetric undercut geometry that creates a form-fit engagement with the support rail. This asymmetric design provides mechanical interlocking that resists high surface loadings in one direction while allowing easy insertion from the other direction, thus maintaining ease of mounting.
2Stability of the object's composition
If traditional framing solutions are used for solar cell laminates, then basic protection is provided, but transportation and installation are cumbersome
Solution Approach 1:
The frame profile serves multiple functions: it protects the edges of the solar cell laminate from liquid ingress, provides mechanical stability through the clamping section, and enables easy mounting and transportation through the profile section with undercut that engages with support rails. This multi-functionality reduces the need for separate components, simplifying transportation and installation while maintaining mechanical stability.
3Reliability
If the frame profile includes undercut portions for secure engagement, then form-fit connection with support rails is achieved, but manufacturing complexity increases
Solution Approach 1:
The undercut portion of the profile section is designed with specific geometric parameters that enable form-fit engagement with the support rail. By carefully selecting the depth, width, and angle of the undercut, the design achieves reliable mechanical interlocking while remaining compatible with standard extrusion manufacturing processes, thus avoiding excessive manufacturing complexity.

AI summary
A frame profile (1) for a solar cell laminate (10) includes a laminate clamping section (2), which comprises two parallel clamping feet (2a, 2b) configured plane and mutually spaced apart for clamped mounting of the solar cell laminate (10); and a profile section (3) adjoining the laminate clamping section (2), which includes a portion formed—by sides (3a, 3b)—for the solar cell laminate (10). Therefore, the sides (3a, 3b) are formed such that the portion includes an undercut at least partially. A solar module (100) with at least one such frame profile (1) has a panel-shaped solar cell laminate (10), which is inserted between the clamping feet (2a, 2b) of the laminate clamping section (2) right up to the portion and is connected to the frame profile (1) of an at least partially framed solar module (100).
