Eave Arrangement Ventilation Profile Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing eaves arrangements for sloping roofs face challenges in preventing soiling and ingress of larger animals while ensuring good ventilation and drainage, as ventilation profiles often reduce airflow efficiency.
Innovation Solution
An eaves arrangement featuring a ventilation profile with a larger transverse extent than the distance between the eaves board and the sub-roof, which includes a ventilation profile with numerous openings to allow airflow while preventing coarse dirt and larger beings from entering, and an eaves profile with a drip leg and fastening leg to manage moisture and installation timing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a ventilation profile with ventilation openings is used to prevent soiling and animal ingress, then protection against dirt and animals is improved, but airflow through the ventilation ducts is reduced
Solution Approach 1:
The ventilation profile extends beyond the straight-line distance between the eaves board and underlayment by projecting into the ventilation duct space. This creates a longer airflow path through the profile's ventilation openings, effectively adding a dimensional component to the ventilation path that compensates for the area reduction caused by the profile's presence.
Solution Approach 2:
The invention changes the geometric parameters of the ventilation profile, specifically making its transverse extent longer than the distance between the eaves board and underlayment. This parameter modification allows the profile to create a longer airflow path that compensates for the reduced open area, maintaining ventilation effectiveness while providing protection.
2Productivity
If the ventilation profile extends longer than the distance between eaves board and underlayment, then airflow path is lengthened to compensate for reduced area, but device complexity increases
Solution Approach 1:
The ventilation profile serves multiple functions simultaneously: it provides protection against dirt and animals through its ventilation openings, extends the airflow path to compensate for area reduction, and integrates with the existing eaves structure. This multi-functionality justifies the increased geometric complexity by delivering multiple benefits from a single component.

AI summary
A roof venting system for the ventilated termination of a sloping roof surface along the eaves comprises: an eaves-side end section of an underlayment of the roof surface; an eaves-side end section of a counter-battening system of the roof surface resting on the underlayment and formed from counter-battens running perpendicular to the eaves; an eaves board of a roof battening system of the roof surface resting on the counter-battening and formed from roof battens running parallel to the eaves; ventilation channels formed by the spaces between two adjacent counter-battens and bounded perpendicular to the roof surface on one side by the end section of the underlayment and on the other side by the eaves board; and a ventilation profile with a multitude of ventilation openings, extending along the eaves and closing off the ventilation channels to the outside by connecting the eaves board to the end section of the underlayment transversely to its longitudinal extent.The section along which the ventilation profile connects the eaves board to the end section of the underlayment perpendicular to its longitudinal extent is longer than the distance between the eaves board and the end section of the underlayment.
