Pan Tile with Angular Side Segments for Roofing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional roofing systems are costly and labor-intensive due to the high number of both pan tiles and exterior roof tiles required, especially when using expensive ceramic materials, and require significant materials for securing, which increases installation time and material costs.
Innovation Solution
A pan tile with a planar base and angularly extending side segments, machine-made from ceramic or other materials, is designed to cover and support a larger area with fewer tiles, allowing for increased spacing between tiles and reduced material usage, facilitating efficient installation and reduced material costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional roofing systems use traditional pan tiles and exterior roof tiles arranged in overlapping rows, then adequate coverage and water resistance are achieved, but the number of tiles required is large, increasing material cost and installation time
Solution Approach 1:
The pan tile is divided into distinct functional segments: a base portion for coverage and side segments for support. This segmentation allows each part to optimize its function, with side segments extending laterally to support exterior tiles at spaced intervals, reducing the total number of pan tiles needed while maintaining structural integrity and coverage.
Solution Approach 2:
The pan tile design transitions from a conventional two-dimensional flat tile to a three-dimensional structure with side segments extending perpendicular to the base. This dimensional addition creates lateral support surfaces that can hold exterior tiles at spaced intervals, effectively increasing the coverage area per tile without compromising structural strength or water resistance.
2Reliability
If ceramic materials are used for both pan tiles and exterior roof tiles to meet customized specifications, then aesthetic appeal and durability are improved, but material cost and installation labor cost increase significantly
Solution Approach 1:
The pan tile with side segments serves multiple functions simultaneously: it provides base coverage for water resistance, lateral support for exterior tiles, and structural stability. This multi-functionality reduces the need for separate support elements, allowing fewer total tiles to achieve the same protective and aesthetic效果, thereby reducing both material and installation costs while maintaining durability.
3Reliability
If a greater number of pan tiles and exterior roof tiles are used to ensure adequate support and coverage, then structural stability and water resistance are improved, but installation time and labor requirements increase
Solution Approach 1:
The side segments of the pan tile are merged with the base to form an integrated structural unit. This merging creates a unified component that provides both coverage and lateral support functions in a single element, eliminating the need for separate support structures and reducing the total number of tiles required, thereby decreasing installation time while maintaining structural stability.
4Reliability
If traditional overlapping arrangements of roof tiles are used to ensure water resistance, then effective water protection is achieved, but the number of tiles and securing materials required increases, raising material costs
Solution Approach 1:
The side segments of the pan tile provide preliminary lateral support for exterior tiles before final securing. This preliminary support structure allows exterior tiles to be positioned and stabilized with fewer securing materials, as the side segments already provide mechanical support and alignment, reducing the quantity of securing materials needed while maintaining water resistance through the overlapping arrangement.

AI summary
A pan tile for use in a roofing system, 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. 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.
