Skylight Protective Cover with Insulating Air Gap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Skylights often suffer from leaks due to issues like bad flashing, worn seals, or cracked glass, leading to costly and time-consuming repairs, and potential damage to building structures.
Innovation Solution
A protective cover for skylights featuring peripheral frames made from materials like metal, plastic, or composite, with a smooth transparent vision surface that allows light transmission, an upper and perimeter mounting flashing system, and a sealing method to secure the cover in place, forming a water barrier and enhancing thermal insulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a skylight is installed to provide natural light, then illumination intensity is improved, but leaks occur due to bad flashing, worn seals, or cracked glass
Solution Approach 1:
The protective cover is nested over the existing skylight, creating a protective enclosure that shields the skylight from water, ice, snow, and debris while preserving the skylight's light transmission function. The cover fits within the roof structure and integrates with existing flashing systems.
Solution Approach 2:
The protective cover acts as an intermediary element between the external environment (water, ice, debris) and the skylight. It intercepts harmful elements before they can reach the skylight, preventing leaks without blocking light transmission.
2Reliability
If repairs are made to fix skylight leaks, then reliability is improved, but time and cost are increased
Solution Approach 1:
The protective cover is installed over the existing skylight before any repair work is needed, providing immediate leak prevention. This preliminary protective measure eliminates the need for time-consuming repairs by preventing damage in the first place.
Solution Approach 2:
The protective cover represents a cost-effective solution compared to expensive skylight repairs or replacements. It provides reliable leak prevention at a lower cost and can be quickly installed without extensive labor.
3Reliability
If a protective cover is installed over the skylight, then leak prevention is improved, but device complexity is increased
Solution Approach 1:
The protective cover utilizes a simple panel structure made of rigid or flexible material that forms a protective shell over the skylight. This thin-film approach provides effective leak prevention without adding significant structural complexity or weight.
Solution Approach 2:
The protective cover system is divided into simple, manageable components including the cover panel, perimeter flashing, and fastening elements. This segmentation allows for easy installation and maintenance while providing comprehensive protection.
4Illumination intensity
If the vision surface is made smooth and transparent, then light transmission is improved, but debris accumulation may occur
Solution Approach 1:
The vision surface is designed with a smooth, slightly curved profile that allows debris and water to slide off easily. The curvature prevents debris accumulation while maintaining high light transmission, combining aesthetic appeal with functional performance.
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
The protective cover effectively prevents leaks, reduces heat loss, and minimizes condensation, providing a temporary or permanent solution to skylight issues while maintaining aesthetic appeal and allowing for easy installation and use.
Implementation Method 1
a vision surface (30) disposed on top of the skylight protective cover made of a smooth transparent material allowing for transmission a plurality of undistorted incoming light rays (35)
Implementation Method 2
The peripheral frame and the upper flashing and perimeter mounting may form a water barrier area
Implementation Method 3
The skylight protective cover may produce an enhanced level of thermal insulation by trapping a layer of insulating air between the skylight protective cover
Implementation Method 4
reduces heat loss from an internal structure that would otherwise melt snow and ice on an exterior of the conventional skylight
Implementation Method 5
The smooth upper surface may prevent the subsequent freezing of water and accumulation of ice on the roof surface that would infiltrate into the structure

AI summary
A skylight protective cover is a weather resistant shroud having flashing about a peripheral edge configured to secure about an existing skylight in a manner which provides a space between the shroud and skylight thereby protecting the skylight from the elements.
