Eaves Ventilation Element With Bendable Spacers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing eaves ventilation elements face challenges in providing secure support over gutter brackets while maintaining ventilation and protection from dirt and small animals, often resulting in sloping or bending due to irregular eaves constructions and complex production processes.
Innovation Solution
The eaves ventilation element features a base profile with protruding fingers and movable, bendable spacers connected by a thin connecting element, allowing for easy separation over gutter brackets by cutting or bending, which maintains support functionality and adaptability to irregular eaves constructions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If spacers are made detachable to allow separation over gutter brackets, then ease of operation is improved, but reliability of support function deteriorates
Solution Approach 1:
The spacer is designed as a one-piece element with a flexible section that allows dynamic movement and bending. This enables the spacer to adapt its shape when encountering gutter brackets, maintaining contact and support function while allowing easy separation by bending the flexible section.
Solution Approach 2:
The spacer is divided into functionally distinct sections: a rigid support section for maintaining distance and a flexible section for adaptation and separation. This segmentation allows the spacer to provide reliable support during normal operation while enabling easy removal when needed by bending at the flexible section.
2Ease of operation
If spacers are made detachable by cutting through a thin flexible joint, then ease of operation is improved, but device complexity worsens
Solution Approach 1:
The spacer is integrated as a one-piece element with the eaves ventilation element, eliminating the need for separate detachable components. The flexible section is incorporated directly into the spacer structure, simplifying the overall device while maintaining ease of removal through bending.
3Ease of operation
If predetermined breaking points are provided for spacer separation, then ease of operation is improved, but manufacturing precision worsens
Solution Approach 1:
Instead of creating predetermined breaking points with specific geometric features requiring high manufacturing precision, the solution uses a flexible section with controlled material properties. The separation is achieved by bending the flexible section, which relies on material flexibility rather than precise geometric breaking points, thereby reducing manufacturing precision requirements.
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
This design ensures secure support and maintains ventilation while allowing easy adaptation to irregular eaves structures, ensuring the eaves ventilation element remains effective and stable even when encountering gutter brackets, preserving the support function and distribution of forces under roofing panels and snow loads.
Implementation Method 1
Each spacer (10) consists of two webs (1) which protrude vertically downward from the underside (31) of the basic profile (30) and are deformable, preferably bendable. Bendable in this context is intended to mean that each of the webs (1) can be moved against the underside (31) of the base profile (30) around an imaginary axis in the area of the connection with the base profile (30).

AI summary
The eaves ventilation element, with spaced apart spacers (10) fastened to the underside (31) of a base profile (30), and each with at least two downwards projecting bridges (1), has each of the bridges movable towards the underside of the base profile. Each of the bridges is movable towards the underside around an imaginary axis in a transition (5). The bridges are deformable, are arranged parallel to each other, and project vertically downwards from the underside of the base profile.
