Baffled Ridge Roll Vent for Airflow and Insect Blocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing roof ridge vents fail to effectively prevent the ingress of insects, water, and other unwanted elements while providing adequate ventilation and structural strength, especially under high winds and varying roof slopes.
Innovation Solution
A flexible, spirally rollable baffled roll vent made from polymer compounds with integral hinges and reinforced supports, featuring louvers and rain baffles to prevent precipitation and particulate entry, and a design that can be easily installed over the roof ridge slot with optional fibrous mats for enhanced protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If larger perforations are used in ventilation panels to increase airflow, then ventilation efficiency is improved, but protection against insects and unwanted elements deteriorates
Solution Approach 1:
The vent panel is divided into multiple small louver slots instead of using large perforations. Each louver creates a narrow opening that allows air to pass through while being too small for insects to enter, thus segmenting the airflow path into numerous small channels that collectively provide adequate ventilation while maintaining insect protection
Solution Approach 2:
Baffles are introduced as intermediary structures that extend into the vent openings from the attic side. These baffles create a physical barrier that interrupts the direct path of insects and rain while still allowing air to flow through the louvers, serving as a mediator between the need for ventilation and the need for protection
2Strength
If rigid structural supports are added to withstand high winds and snow loads, then structural strength is improved, but ease of installation and flexibility for different roof slopes deteriorates
Solution Approach 1:
The vent panel incorporates flexible polymer materials and hinge connections that allow the structure to dynamically adapt to different roof slopes and weather conditions. The panel can flex and conform to various roof angles during installation, and the flexible material allows for thermal expansion and contraction under wind and snow loads, maintaining structural integrity without requiring rigid supports that would complicate installation
Solution Approach 2:
The patent uses flexible polymer compounds with specific mechanical properties that change under different conditions. The material's flexibility and elasticity parameters allow it to maintain strength under load while remaining easy to handle and install. The polymer's properties enable it to conform to different roof slopes without requiring additional structural components
3Stability of the object's composition
If the vent is manufactured as a rigid pre-formed panel, then structural stability is improved, but adaptability to different roof slopes and ease of handling deteriorates
Solution Approach 1:
The vent panel is constructed from flexible polymer compounds that form a shell structure capable of bending and conforming to different roof slopes. This flexible shell maintains its structural integrity and stability once installed, while allowing the panel to be easily shaped and adapted to various roof configurations during installation. The flexible material provides both handling ease and final structural stability

AI summary
A baffled roll vent for covering the ridge slot of a roof for allowing ventilation from the space of a building below the ridge slot, the baffled roll vent having a first vent section having a male part and a second vent section having a female part, wherein the male part of the first vent section attaches to the female part of the second vent section. The male and female parts are preferably located at opposite edges of each vent section, allowing each vent section in the baffled roll vent to attach to the next vent section in the baffled roll vent. A center hinge allows flexing of the panel to conform to the pitch of a roof.
