Snap-On Rail Mounting for Fast, Moisture-Safe Solar Rooftops
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional solar photovoltaic module mounting systems require complex procedures and tools, often compromising the moisture barrier and increasing installation costs and time, especially on rooftops where multiple solar modules are needed for substantial energy generation.
Innovation Solution
A mounting assembly that includes rails with snap brackets and connectors, allowing for tool-free installation and secure fixation of solar modules on rooftops, while maintaining a moisture barrier through flashings and adjustable components to accommodate different roofing types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional mounting systems penetrate the mounting surface to engage with the superstructure, then secure fixation of solar modules is achieved, but the moisture barrier is compromised and installation complexity increases
Solution Approach 1:
The mounting system is divided into separate functional components: a non-penetrating mounting surface interface (flashing) and a separate engagement mechanism (rail with clips) that connects to the superstructure without penetrating the roofing material. This segmentation allows the moisture barrier to remain intact while still achieving secure fixation through the alternative engagement path.
2Reliability
If conventional mounting systems use multiple tools and complex procedures, then secure installation is achieved, but installation time and cost increase
Solution Approach 1:
The rail assembly incorporates self-aligning features and snap-fit connections that automatically position and secure components without requiring precise manual alignment or specialized tools. The clips engage with the superstructure automatically when the rail is positioned, and the end caps provide self-centering during installation, eliminating the need for complex procedures and reducing installation time while maintaining secure installation.
3Adaptability or versatility
If conventional mounting systems require custom tools, then specific mounting requirements are met, but installation cost and complexity increase
Solution Approach 1:
The mounting system is designed with universal components that can be installed using standard construction tools (drills, screws, common hand tools) rather than custom-specialized tools. The rail, clips, and end caps form a multi-functional assembly that adapts to different roof types through the flashing interface while maintaining consistent installation procedures, thereby reducing both tool requirements and overall system complexity.

AI summary
A mounting assembly to mount frames on a mounting surface, the mounting assembly having rails that supports the frames, each rail having an internal side adjacent with an internal recess, and an external side opposite to the internal side with lip; and roof mounting assemblies to affix the rails onto the mounting surface. Each mounting assembly having a mounting block that is fixable to the mounting surface, a mounting plate that is fixable to the mounting block, and a pair rail snap brackets formed at extremities of the mounting plate that receives and locks the rails in place, each rail snap bracket of the pair of rail snap brackets having a pair of notches that lodges in the internal recess of the rail to lock the rail in place and a hook that receives the lip.
