Roof Ridge Vent Mat Structure for Rain-Blocking Ventilation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing roof ridge vents are not efficiently manufactured and installed, requiring specialized labor and additional materials, and lack a continuous, indeterminate-length design for easy storage and installation, while also failing to prevent unwanted intrusion of rain and snow.
Innovation Solution
A continuous, elongate mat of randomly convoluted polymeric filaments with an openwork structure, featuring hollow recesses and a latticework design that allows for easy installation with standard tools, prevents fastener passage and allows wind-blown rain and snow to pass through, eliminating the need for additional reinforcement layers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a traditional ridge vent with reinforcement layer is used, then fastener passage is prevented, but device complexity and manufacturing cost increase
Solution Approach 1:
The invention removes the separate reinforcement layer from the ridge vent structure. The top layer of the mat itself is engineered to provide fastener passage prevention without requiring an additional reinforcement layer, thereby simplifying the overall structure while maintaining the strength function.
Solution Approach 2:
The top layer of the mat performs multiple functions: it provides fastener passage prevention, maintains structural integrity, and serves as the surface for fastener attachment. This multi-functionality eliminates the need for a separate reinforcement layer, reducing device complexity while maintaining strength.
2Ease of operation
If a continuous roll-form mat is used, then ease of installation and storage improve, but manufacturing precision and edge definition worsen
Solution Approach 1:
The invention uses a continuous roll-form mat that is dynamic in nature, allowing it to be unrolled and installed continuously along the roof ridge. This provides ease of installation and storage while the manufacturing process maintains sufficient edge definition through controlled extrusion and cutting mechanisms.
Solution Approach 2:
The invention changes the manufacturing parameters to produce a continuous mat with controlled edge definition. By adjusting extrusion parameters and cutting precision, the manufacturer can maintain adequate edge definition while producing a continuous roll-form product that is easy to install and store.
3Object-affected harmful factors
If hollow recesses are added to the mat, then rain and snow intrusion is prevented, but manufacturing complexity increases
Solution Approach 1:
The invention incorporates hollow recesses within the mat structure that create a porous configuration. These recesses prevent wind-blown rain and snow from passing through the mat while maintaining airflow for ventilation. The hollow recesses are integrated into the mat manufacturing process, minimizing additional manufacturing complexity.
4Ease of operation
If standard pneumatic roofing nail guns are used, then ease of operation improves, but fastener head support reliability may worsen
Solution Approach 1:
The invention designs the top layer of the mat to self-provide fastener head support. The engineered surface of the top layer naturally catches and supports standard pneumatic roofing nail gun fasteners without requiring additional components or specialized tools, maintaining both ease of operation and reliability.
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 solution enables efficient, inexpensive manufacturing and installation of a roof ridge vent that provides effective ventilation while preventing rain and snow intrusion, using standard pneumatic roofing tools and maintaining structural integrity.
Implementation Method 1
The openwork upper face is formed of randomly convoluted filaments formed to provide a relative flat surface of sufficient density to catch heads of fasteners and to prevent heads of fasteners from passing through the mat
Implementation Method 2
the upstanding openwork walls of the latticework structure extend transverse to the side edges and transverse to a longitudinal axis of the mat... no unobstructed passageway extends through the mat through which wind-blown rain and snow can freely pass
Implementation Method 3
the mat can consist solely of melt-spun thermoplastic polymeric filaments extruded in overlapping, irregularly-looped patterns with the polymeric filaments being self-bonded and fused at random points of intersection without bonding agents or inserts

AI summary
A roof ridge vent mat for installation overlying an open roof ridge to provide ventilation to a space beneath a roof is provided. The ridge vent mat is a continuous elongate material of randomly convoluted polymeric filaments having an openwork upper face, an openwork lower face, a plurality of hollow recesses extending into the mat and opening into the lower face, and opposite longitudinally extending openwork side edges. The openwork upper face is formed of randomly convoluted filaments formed to provide a relatively flat surface of sufficient density to catch heads of fasteners. The plurality of hollow recesses is defined by a plurality of upstanding openwork walls of convoluted filaments that extend from the upper face to the lower face of the mat. The upstanding openwork walls are arranged in a latticework structure such that no unobstructed passageway extent through the mat through which wind-blown rain and snow can freely pass into the side edges of the mat and laterally pass through the mat. A ventilated roof ridge assembly including the vent is provided.
