Ventilated Frame Housing with Rotating Fan Element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing frame systems with integrated fan elements face challenges such as increased assembly costs, complexity, and unsightly design due to large housing protrusions, which compromise thermal insulation and statics, and require complex reversible fans for ventilation direction reversal.
Innovation Solution
A compact housing with a unidirectional blower that allows air conveyance reversal by interacting with the fan element, integrated into the frame profile with a matching outer contour, reducing assembly parts and complexity, and maintaining technical functions like thermal insulation and statics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a large housing is used to accommodate the fan element, then the fan element can be securely housed, but the housing protrudes significantly over the frame profile cross-section resulting in a clunky and unsightly look
Solution Approach 1:
The housing is nested within the frame profile cross-section, with the outer contour of the housing corresponding at least in sections to the outer contour of the frame profile. This allows the housing to be accommodated within the existing frame structure without protruding, achieving both secure housing and aesthetic appearance.
2Reliability
If a large housing is used to accommodate the fan element, then the fan element can be securely housed, but the existing profile frame must be almost completely removed resulting in serious intervention in the constructive structure
Solution Approach 1:
The housing is designed as a separate, modular component that can be inserted into a receiving space within the frame profile without requiring removal of the entire frame structure. This segmentation allows independent installation and maintenance while preserving the integrity of the frame.
3Adaptability or versatility
If a reversible fan is used to change ventilation direction, then air flow direction can be reversed, but the fan becomes complex
Solution Approach 1:
Instead of using a mechanically complex reversible fan, the patent employs a fixed unidirectional blower combined with a rotatable fan element that has slots at different angular positions. By rotating the fan element to different angular positions, the ventilation direction is reversed without requiring the blower to change rotation direction, thereby simplifying the fan mechanism.
4Reliability
If multiple parts are used to assemble the frame system, then the fan element can be securely fixed, but the assembly costs and complexity increase
Solution Approach 1:
The housing is designed to correspond in contour with the frame profile, allowing it to be integrated directly into the frame structure without requiring additional fastening strips or separate fixation components. This merging of the housing with the frame profile reduces the number of parts and assembly steps while maintaining secure fixation.
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 simplifies assembly, reduces errors, and maintains the frame's technical properties while enabling compact and efficient air flow reversal without altering the fan's direction, ensuring unobtrusive integration and effective ventilation.
Implementation Method 1
A blower 20 is arranged in the housing 8, which conveys the air in one direction

AI summary
The present invention relates to a frame for use in a wall opening having a frame profile cross-section, comprising a receiving space (4) for receiving a ventilator element (10), the main axis of which extends parallel to the longitudinal extension of the frame profile (2). The invention further relates to a housing (8) having a ventilator (20) for use in the frame. The ventilator element (10) is disposed in the housing (8) with an outside contour corresponding at least in sections to the outer contour of the adjacent frame profile cross-section. The housing (8), and a ventilator element (10) disposed therein rotatably about the longitudinal axis thereof, has a plurality of ventilation openings, which are distributed across the length of the housing (8) and disposed in an appropriate longitudinal position and which produced jointly formed air openings. The frame is produced in that the frame profile (2) is recessed in sections, and a housing (8) is inserted in the recessed section in a receiving space (4) in the frame profile (2).
