Roof Shingle Tile with Interlocking Gutters for Wind and Leakage Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing roof shingles require significant overlap to secure fasteners and prevent water infiltration, leading to material wastage and increased risk of shingles lifting in high winds, while minimizing overlap compromises leakage and stability.
Innovation Solution
The design features a roof shingle tile with a top gutter, side gutter, and overhangs that allow for interlocking with adjacent tiles, directing water flow onto the weather-facing surface and using fasteners through the top gutter for secure installation, reducing the need for extensive overlap and enhancing wind resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If significant overlap is used to secure fasteners and prevent water infiltration, then leakage protection is improved, but material usage increases and installation complexity increases
Solution Approach 1:
The shingle is divided into distinct functional segments: a top gutter portion for water collection, side gutters for water channeling, and interlocking edges for structural connection. This segmentation allows each portion to perform its specific function efficiently, enabling reduced overlap while maintaining protection.
Solution Approach 2:
The patent introduces intermediary water channeling structures (side gutters with raised partitions) that mediate between water collection and discharge. These intermediaries guide water flow precisely along designated paths, preventing lateral spread and enabling tighter overlaps without compromising drainage effectiveness.
2Reliability
If significant overlap is used to prevent water infiltration, then leakage protection is improved, but installation time increases
Solution Approach 1:
The shingle design incorporates pre-formed gutters, channels, and interlocking features during manufacturing. These preliminary structures are ready for immediate installation, eliminating the need for on-site modifications or extensive alignment adjustments, thereby reducing installation time while maintaining protection standards.
Solution Approach 2:
The shingle's interlocking edges and gutter structures are designed to self-align and self-secure during installation. The tongue-and-groove mechanism and overlapping gutters automatically position themselves correctly, reducing the need for precise manual alignment and accelerating the installation process.
3Loss of substance
If minimal overlap is used to reduce material usage, then material efficiency is improved, but leakage risk increases
Solution Approach 1:
The shingle design applies different structural qualities to different regions: the top gutter portion has enhanced water collection capacity, side gutters have raised partitions for precise channeling, and interlocking edges provide structural continuity. This localized optimization allows minimal overlap while maintaining protection through enhanced local functionality.
Solution Approach 2:
The shingle incorporates hydraulic principles through sloped gutters and raised partitions that direct water flow along predetermined paths. The slope geometry and partition structures utilize gravity and surface tension to control water movement, ensuring efficient drainage with minimal overlap.
4Loss of substance
If minimal overlap is used to reduce material usage, then material efficiency is improved, but shingle stability in high winds deteriorates
Solution Approach 1:
The shingle design features nested interlocking structures where the tongue portion fits into the groove of adjacent shingles, creating a interlocked network. This nesting mechanism provides structural cohesion and wind resistance without requiring extensive overlap, as the interlocking edges create a unified stable assembly.
Solution Approach 2:
The shingle combines multiple functional elements (gutter portions, side gutters, interlocking edges, and weather-resistant materials) into a composite structure. This composite design integrates water management and structural stability functions, enabling minimal overlap while maintaining both leakage protection and wind resistance.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration minimizes material usage, reduces leakage risk, and improves shingle stability in high winds by allowing water to flow onto adjacent tiles, ensuring it is directed off the roof without infiltrating the underlying deck.
Implementation Method 1
the top gutter may include a sloped lower portion for directing water to the side gutter when installed on a roof
Implementation Method 2
The side gutter may, in some embodiments, include one or more raised partitions forming water channels

AI summary
A novel roof shingle tile and method of installation is presented. The roof shingle may include a first side opposite a second side, a top edge opposite a bottom groove, a top gutter, and a side gutter. The bottom groove may extend along a bottom edge of the tile that includes a bottom edge of the side gutter, and the top edge may include a tongue portion sized to fit within the bottom groove of a vertically adjacent tile. The second side may also include an overhang portion sized to overlap the side gutter of a horizontally adjacent tile. When installed, the shingle tiles may create a water resistant roof surface.
