Extractor Fan Housing Rotation for Flexible Ceiling Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing extractor devices integrated into ceilings face challenges in adapting to structural conditions, requiring complex installation processes and adjustments, especially when the air outlet position needs to be changed.
Innovation Solution
The extractor device features a fan housing and fan that can be attached separately to the extractor housing, with fastening means allowing for relative positioning and rotation, enabling easy adjustment of the air outlet direction without disturbing other components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the fan box is integrated into the extractor housing as a single unit, then the structural strength is improved, but the adaptability to different structural conditions deteriorates
Solution Approach 1:
The invention divides the integrated fan box structure into separate components: the extractor housing and the fan housing that can be attached separately. This segmentation allows each component to be optimized independently while maintaining overall structural integrity, resolving the contradiction between structural strength and adaptability.
2Manufacturing precision
If the fan box is fixed in a specific orientation, then the manufacturing precision is improved, but the ease of operation deteriorates
Solution Approach 1:
The invention introduces rotational capability to the fan housing through circular fastening means, transforming the fixed orientation into a dynamic, adjustable configuration. This allows the fan housing to be rotated to different orientations during installation while maintaining precise positioning through the fastening mechanism.
3Device complexity
If the fan and fan housing are attached together as a single unit, then the device complexity is reduced, but the ease of repair deteriorates
Solution Approach 1:
The invention separates the fan assembly from the fan housing attachment to the extractor housing, allowing the fan housing to be detached independently. This segmentation enables maintenance personnel to access and service the fan without removing the entire housing assembly, improving ease of repair while maintaining manageable device complexity.
