Solar Roof Tile Holding Beam With Drain Channel Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing holding means for solar roof tiles on pitched roofs often fail to effectively prevent water ingress and ensure efficient drainage, leading to potential damage and reduced solar panel efficiency due to inadequate sealing and wind resistance.
Innovation Solution
A holding means comprising an oblong beam with supports on upper and lower battens, a drain channel for water management, and elastic materials for sealing and protection, allowing for secure fastening and efficient air circulation to enhance panel efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If holding means are mounted on pitched roofs to secure solar roof tiles, then the solar panels are firmly fixed and stable, but water ingress occurs due to inadequate sealing and drainage
Solution Approach 1:
The holding means is divided into functionally independent components: support elements for fixation, drain channels for water drainage, and rest elements for panel support. This segmentation allows each component to perform its specific function optimally - mechanical fixation through supports while water management is handled by dedicated drain channels, preventing water ingress without compromising panel stability
Solution Approach 2:
The holding means acts as an intermediary element between the pitched roof structure and the solar roof tiles. It provides a transition zone that includes sealing elements and drain channels, mediating between the roof's structural requirements and the panels' protection needs, thereby preventing direct water contact with panels while maintaining firm fixation
2Ease of manufacture
If conventional holding means are used on pitched roofs, then installation is simple, but wind resistance is insufficient leading to panel displacement
Solution Approach 1:
The holding means incorporates locally optimized features: support elements with bearing areas positioned at specific locations to maximize wind resistance, drain channels strategically placed along longitudinal edges, and rest elements configured to hold panels securely. This local quality enhancement provides superior wind resistance in critical areas while maintaining overall installation simplicity through modular design
Solution Approach 2:
The holding means extends in the longitudinal direction x with drain channels running along the length, adding a dimensional aspect that enhances wind resistance by distributing forces along the entire panel length rather than at discrete points, while maintaining simple installation through this linear, extended structure
3Object-affected harmful factors
If drain channels are added to holding means for water drainage, then water protection is improved, but device complexity increases
Solution Approach 1:
The drain channels are merged with the holding means structure itself, forming an integrated component rather than a separate addition. The holding means simultaneously provides mechanical support, sealing, and water drainage functions through this unified structure, improving water protection without proportionally increasing complexity as would separate drainage systems
Solution Approach 2:
The holding means is designed as a multi-functional element that combines fixation supports, sealing elements, and drain channels into a single universal component. This allows one structure to perform multiple functions - mechanical support, water sealing, and drainage - thereby improving water protection while minimizing the increase in overall device complexity through functional integration

AI summary
A solar roof tile for covering a pitched roof and for being mounted to battens of the pitched roof by means of a holding means which includes an oblong beam extending in a longitudinal direction and including a first support supported in a mounted position on a first upper batten of the pitched roof and a second support supported in the mounted position on a second lower batten. At least one rest is interconnected to the solar roof tile as a separate part for holding the solar roof tile on the holding means.
