Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional solar module mounting systems are costly and labor-intensive, often requiring roof penetrations that can lead to leaks and inefficiencies due to lack of air-gaps, and existing adhesive-based systems face issues with heat-induced adhesive failure and reduced module efficiency.
Innovation Solution
A system utilizing adhesion sheets secured to a roof with adhesives and clamps or standoffs that allow solar modules to be attached without penetrating the roof, maintaining an air-gap for improved cooling and efficiency, and using flexible adhesion sheets to accommodate roof contours.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional mounting systems use mechanical fasteners and roof penetrations, then secure attachment is achieved, but installation cost and labor increase, and risk of roof leaks worsens
Solution Approach 1:
The patent replaces conventional mechanical fastening systems (screws, bolts, penetrating clips) with an adhesive-based mounting system. Adhesive sheets are applied to the roof surface and bonded to solar module frames or backsheets, eliminating the need for mechanical penetrations into the roof structure. This substitution reduces installation complexity, labor requirements, and potential leak paths while maintaining secure attachment through the adhesive bonding mechanism.
Solution Approach 2:
The patent introduces adhesive sheets as an intermediary element between the roof surface and solar modules. These adhesive sheets serve as a mediating bonding layer that distributes loads, accommodates thermal expansion, and provides a sealed interface without requiring direct mechanical penetration of the roof structure. The adhesive sheet acts as a flexible intermediary that reconciles the conflicting requirements of secure attachment and roof protection.
2Ease of operation
If solar modules are mounted directly to the roof without air-gap, then installation simplicity increases, but module efficiency decreases due to heat buildup
Solution Approach 1:
The patent segments the mounting system into distinct functional layers: adhesive sheets for attachment, air-gap space for thermal management, and modular components for flexibility. By creating a separated structure with the air-gap between the roof surface and solar modules, the system maintains installation simplicity through the adhesive bonding while enabling effective heat dissipation through convection and radiation in the gap space, thus preserving module efficiency.
Solution Approach 2:
The patent applies different functional qualities to different regions of the mounting system. The adhesive sheets provide localized bonding and sealing at the interface between roof and module support structure, while the air-gap region provides localized thermal management. This spatial differentiation of functions allows the system to achieve both installation simplicity and energy efficiency by optimizing each region for its specific purpose.
3Stability of the object's composition
If rigid adhesion sheets are used for mounting, then structural stability improves, but adaptability to roof contours worsens
Solution Approach 1:
The patent employs adhesive sheets with dynamic mechanical properties that allow them to deform and conform to various roof contours while maintaining bonding stability. The adhesive material exhibits viscoelastic behavior, enabling it to flex with roof movements, thermal expansion, and contour variations without compromising the structural stability of the mounting system. This dynamic adaptation allows the same adhesive sheet to effectively mount modules on different roof types and orientations.
