Adjustable Roof Hook Structure for Easier Solar Module Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing roof hooks for solar installation modules on roofs have poorly reachable fastening elements and lack adjustment possibilities for different pantiles and solar installation modules, making mounting difficult and inefficient.
Innovation Solution
A modular roof hook design with a first fastening section extending in the X and Y directions and a second fastening section perpendicular to it in the Z direction, featuring adjustable, obliquely acting fasteners and engagement elements like ribs, allowing for easy access and adaptation to various roof types and modules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If roof hooks are made integral and welded from two segments, then structural strength is improved, but mounting difficulty increases due to poorly reachable fastening elements
Solution Approach 1:
The roof hook is divided into two separate components: a U-shaped hook component and a fastening component. This segmentation allows the fastening elements to be positioned on the hook component where they are easily accessible, while the hook component maintains its structural integrity through the U-shaped design that engages with roof tiles.
Solution Approach 2:
The hook component acts as an intermediary element between the roof structure and the fastening system. It provides a mounting surface with accessible fastening elements while transferring loads to the roof tiles through its U-shaped engagement, resolving the conflict between structural strength and mounting ease.
2Ease of manufacture
If roof hooks are made integral, then manufacturing simplicity is improved, but adaptability to different pantiles and solar modules decreases
Solution Approach 1:
The fastening component is designed to be adjustable and repositionable on the hook component, allowing the system to adapt to different pantile configurations and solar module sizes. This dynamic adjustment capability is achieved through movable fastening elements that can be positioned at different locations on the hook.
Solution Approach 2:
The hook component serves multiple functions: it engages with various pantile types through its U-shaped design, provides a mounting surface for different solar module configurations, and supports adjustable fastening elements. This multi-functionality enables a single hook design to work with diverse roof and module combinations.
3Strength
If fastening elements are positioned for structural integrity, then strength is improved, but accessibility for mounting deteriorates
Solution Approach 1:
The fastening elements are positioned on the outer surface of the U-shaped hook component, utilizing the three-dimensional space of the hook structure. This spatial arrangement allows fastening elements to be located at accessible positions on the hook's exterior while maintaining structural integrity through the U-shaped engagement with roof tiles.

AI summary
A roof hook for mounting of solar installation modules on roofs. The roof hook has a first fastening section, which extends in the X and Y direction for fixing a roof hook, a hook-shaped mount for fixing the solar installation module or a fastening profile for solar installation modules and a second fastening section which runs perpendicular to the first fastening section in the Z direction from the latter. The mount is adjustable on the second fastening section in the Z direction, and fasteners act obliquely to the Z direction for fixing the mount on the fastening section.
