Modular Ventilation Housing Flange Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for ventilation and screen device housings are inflexible and expensive due to their limited compatibility with various window frame types, requiring multiple stops and modifications to achieve good water- and airtightness and proper airflow, which affects functionality.
Innovation Solution
A modular housing design featuring a basic flange profile with interchangeable inner and outer flange profiles, along with a filler piece, allowing for adjustable flange widths and heights to accommodate different frame systems without compromising functionality, using click-fit connections and elastic materials for ease of assembly and sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a housing is designed with a fixed flange size to match specific window frame types, then good water- and airtightness is achieved for those frame types, but the housing becomes incompatible with other frame types requiring different stops and modifications
Solution Approach 1:
The flange is divided into modular components: a basic flange profile that forms the core structure, and interchangeable inner flange profiles that can be attached or removed. This segmentation allows the housing to adapt to different frame types by swapping only the inner flange profile while keeping the basic structure intact, reducing the number of complete stops needed.
Solution Approach 2:
The flange configuration is made dynamic through the ability to attach and detach different inner flange profiles to the basic flange profile. This transforms a static, frame-type-specific flange into a dynamic, adjustable flange system that can accommodate various frame widths and seal types without requiring permanent modifications to the housing.
2Reliability
If different stops are provided for many frame types to ensure proper sealing and fit, then good water- and airtightness is achieved, but the solution becomes inflexible and expensive
Solution Approach 1:
The basic flange profile is designed as a universal component that can work with multiple frame types. By providing a standardized basic flange structure with attachable inner flange profiles, the housing achieves multi-functionality, serving as a universal mounting solution for various frame types while maintaining reliable sealing through the adjustable flange configuration.
Solution Approach 2:
The flange dimensions and configuration are made adjustable by changing which inner flange profile is attached to the basic flange profile. This allows the same basic housing structure to adapt to different frame parameters (widths, seal types) without requiring complete redesign or multiple manufacturing variants, reducing manufacturing complexity and cost.
3Adaptability or versatility
If the width of the housing is changed to adapt to different glazing widths, then the flange becomes adaptable to different frame sizes, but the air flow passage and device functionality are affected
Solution Approach 1:
The housing is segmented into distinct functional zones: the base body containing the air flow passage and device components, and the flange structure for mounting. By making only the flange portion adjustable through interchangeable profiles while keeping the base body fixed, the design allows width adaptation without affecting the air flow passage geometry or device functionality.
4Adaptability or versatility
If multiple profiles are used to construct an adaptable flange, then the housing can accommodate different frame types, but the device becomes more expensive
Solution Approach 1:
The flange system is segmented into a standardized basic flange profile and variable inner flange profiles. This segmentation allows for a manageable set of interchangeable components rather than requiring multiple complete housing variants, reducing overall system complexity while maintaining adaptability.
Solution Approach 2:
The basic flange profile serves as a universal mounting structure that works with all frame types when combined with the appropriate inner flange profile. This universal base reduces the total number of unique components needed compared to having separate complete housings for each frame type.
