Pan Tile Roofing System with Segmented Support and Solar Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional roofing systems are costly and labor-intensive due to the high number of expensive ceramic tiles required, both for the underlying and exterior roof coverings, which also necessitate significant material for securing, especially on sloped roofs.
Innovation Solution
A pan tile system with a machine-manufactured, fiber glass or ceramic base and angled side segments that supports a reduced number of exterior tiles, allowing for increased spacing and reduced material usage, including the use of photovoltaic systems integrated into the tiles for energy generation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional roofing systems use traditional overlapping tiles for both underlying and exterior coverings, then adequate protection and structural integrity are achieved, but material costs and labor requirements increase significantly
Solution Approach 1:
The roofing system is divided into two distinct functional layers: pan tiles serving as the underlying support structure and exposed tiles as the exterior protective layer. This segmentation allows each layer to be optimized for its specific function, reducing the total number of tiles needed while maintaining overall system integrity and protection.
Solution Approach 2:
The pan tiles are designed to serve multiple functions simultaneously: providing structural support for the roof, creating a stable base for securing exterior tiles, and forming part of the overall protective envelope. This multi-functionality reduces the need for separate structural and protective elements.
2Reliability
If traditional overlapping tile arrangements are used on sloped roofs, then adequate water protection is achieved, but the number of securing materials required increases significantly
Solution Approach 1:
The roofing system segments the water protection function between the pan tiles (which provide the primary waterproof barrier on sloped surfaces) and the exposed tiles (which provide additional protection at the exterior face). This segmentation allows for reduced use of securing materials compared to traditional systems where every tile requires extensive fastening.
3Reliability
If expensive ceramic tiles are used for both underlying and exterior roof coverings, then durability and aesthetic quality are maintained, but overall material cost becomes prohibitive
Solution Approach 1:
The system applies different quality levels to different parts of the roofing structure: durable ceramic or concrete pan tiles are used where structural support and weather resistance are critical, while the exposed tiles can be made from various materials including lighter-weight options. This local differentiation maintains durability where needed while reducing overall material cost.
Solution Approach 2:
The roofing system can combine different materials in the two-layer structure, such as using ceramic pan tiles with concrete or alternative material exposed tiles. This composite approach allows optimization of each layer for its specific requirements while controlling overall material costs.
4Reliability
If hand-made or customized ceramic tiles are used to meet specifications, then aesthetic and functional requirements are satisfied, but manufacturing cost and installation time increase
Solution Approach 1:
By separating the roofing into pan tiles and exposed tiles with different functional requirements, the system allows standardized mass-production of the structural pan tiles while permitting more customized exposed tiles. This segmentation enables faster installation of the majority of tiles while still allowing aesthetic customization where visible.
Solution Approach 2:
The system allows variation in tile parameters (material type, shape, size) primarily in the exposed tile layer where aesthetics are important, while the pan tiles can maintain standardized parameters for efficient manufacturing and installation. This parameter differentiation improves productivity without sacrificing specification compliance.

AI summary
A pan tile for use in a roofing system and assembly, wherein a plurality of such pan tiles are disposed in confronting, supported relation on an underlying roof support and in underlying, at least partially supporting relation to plurality of overlapping, exteriorly exposed roof tiles, wherein the pan tiles may be structured individually or integrally in longitudinal arrays. The pan tile includes a planar base and two oppositely disposed planar side segments extending outwardly from opposite peripheries of said base at a common, preferred obtuse angle. Leading and trailing ends of pan tiles have a greater and lesser transverse dimension respectively, wherein the side segments or oriented in a converging configuration extending from the leading end to the trailing end of the pan tile. Solar energy systems may also be incorporated in the individual pan tiles and/or the longitudinal arrays thereof. The roofing assembly may further include a heat dissipating assembly and/or a stabilizing assembly.
