Adjustable Roof Hook Assembly for Easier Solar Module Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing roof hooks for mounting solar system modules on roofs face challenges with awkward assembly due to hard-to-reach fasteners and limited adjustment options for different roof tiles and solar system modules, leading to complex installations.
Innovation Solution
A modular roof hook design featuring force-fitting connections between components, with easily accessible adjusting elements and obliquely positioned fasteners, allowing for perpendicular adjustment and simplified installation, and incorporating reinforcing ribs for stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional integral or welded roof hooks are used, then structural strength is maintained, but assembly becomes awkward due to hard-to-reach fasteners and lacks adjustment options
Solution Approach 1:
The roof hook is divided into multiple modular components: a first component with a first fastening section for roof attachment, a second component with a second fastening section and holder for solar module attachment, and a connecting element joining them. This segmentation allows independent optimization of each component and enables adjustment through relative positioning of modules, resolving the contradiction between assembly ease and adaptability.
2Strength
If fasteners are positioned for structural integrity, then strength is improved, but accessibility deteriorates making assembly difficult
Solution Approach 1:
The connecting element joins the first and second components at an oblique angle rather than perpendicular to the roof surface. This dimensional change in fastener orientation provides easier accessibility for assembly while maintaining structural integrity through the angled connection geometry that distributes loads effectively.
3Adaptability or versatility
If modular design with multiple components is used, then adjustment options increase, but device complexity increases
Solution Approach 1:
While the roof hook uses multiple components for adjustability, each component is designed as a self-contained module with integrated functions. The first component combines roof interface and positioning features, the second component integrates the holder and second fastening section, and the connecting element provides both structural connection and adjustment capability. This merging of functions within modules reduces overall system complexity despite the multi-component design.
