Solar Module Frame Corner Assembly With Drainage Channels

The patent applies composite materials by combining a corner connector made of aluminum with a corner element made of plastics material. This allows each component to be optimized for its specific function: the aluminum connector provides structural strength and stability, while the plastics element enables cost-effective production through injection molding and offers design flexibility. The heterogeneous material combination resolves the contradiction by achieving both production efficiency and functional optimization.

The patent segments the corner assembly into two distinct components: an aluminum corner connector and a plastics corner element. This segmentation allows each part to be manufactured independently using optimal processes for that material, then assembled together. The aluminum connector can be extruded or formed with precise structural features for stability, while the plastics element can be injection molded for cost-effectiveness. This segmentation resolves the contradiction by distributing manufacturing complexity across different components with different material requirements.

The patent integrates liquid drainage channels directly into the corner element structure, making the corner element serve multiple functions: structural protection, aesthetic finishing, and liquid drainage. The channel features are formed as integral parts of the injection-molded plastics corner element, eliminating the need for separate drainage components. This multi-functionality approach resolves the contradiction by preventing corrosion through built-in drainage while maintaining relatively simple overall frame structure.
