Rollable ridge vent
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Unventilated or under-ventilated attics can lead to condensation and ice blockages on roofs, causing damage to building components, and existing ridge vents may not effectively prevent water and foreign matter from entering the attic while allowing air to exit.
Innovation Solution
A rollable ridge vent system with a top panel, side portions, and staggered inner and outer walls, featuring louvers and prongs for air flow, which can be flexed to match the roof slope and securely fastened, allowing air to exit while preventing water entry, and can be connected in sections to cover long roof ridges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional ridge vents are used to allow air to exit the attic, then ventilation is provided, but water and foreign matter can enter the attic through the same opening
Solution Approach 1:
The vent structure is segmented into multiple functional layers: an outer shell with water-shedding geometry, an inner core with filtration capability, and louvers for controlled airflow. This segmentation allows each layer to address specific functions (water protection, filtration, ventilation) simultaneously, resolving the contradiction between allowing air exit and preventing water/debris entry
Solution Approach 2:
The patent introduces intermediary structures between the attic interior and exterior environment: a water-shedding outer shell that intercepts water before it reaches the vent opening, and a filter medium that intercepts foreign matter. These intermediaries allow beneficial airflow while blocking harmful substances
2Productivity
If ridge vents are installed to prevent condensation and ice dams, then attic ventilation is improved, but the structural integrity and water protection of the roof ridge may be compromised
Solution Approach 1:
The patent employs a shell structure with specific geometric features that flexibly adapt to roof ridges while maintaining water-shedding capability. The shell acts as a protective film over the vent opening, providing water protection without compromising ventilation function for condensation prevention
3Object-affected harmful factors
If the ridge vent structure is made complex to prevent water entry, then water protection is improved, but the device complexity and installation difficulty increase
Solution Approach 1:
The patent merges multiple protective functions into a single integrated vent assembly: the outer shell with water-shedding geometry, the inner core with filtration, and the louver system are combined into one unit that performs water protection, filtration, and ventilation simultaneously. This merging reduces installation complexity compared to separate components while maintaining comprehensive protection
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 rollable ridge vent effectively ventilates attics, prevents condensation and ice blockages, and provides a secure barrier against water and debris, ensuring the integrity of the roof and attic components while allowing for efficient airflow.
Implementation Method 1
allowing a flow of air to exit from the open ridge through the ridge vent

AI summary
A rollable ridge vent for covering an open ridge of a roof and for allowing a flow of air to exit from the open ridge through the ridge vent includes a top panel having a center portion, a left side portion, and a right side portion, in which the top panel includes a plurality of louvers for allowing a flow of air to exit the ridge vent. In addition, the rollable ridge vent includes a spaced apart series of inner walls and a spaced apart series of outer walls extending downward from the left side portion of the top panel. The spaced apart series of inner walls and the spaced apart series of outer walls of the left side portion are staggered. The rollable ridge vent also includes a spaced apart series of inner walls and a spaced apart series of outer walls extending downward from the right side portion of the top panel. The spaced apart series of inner walls and the spaced apart series of outer walls of the right side portion are staggered.
