Ventilation channel module, ventilation system, building wall
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ventilation systems for buildings often compromise aesthetic appeal and structural integrity of outer wall layers, particularly clinker brick walls, due to the need for ventilation ducts that require visible installations or significant tapering, which weakens the wall structure.
Innovation Solution
A ventilation duct module with a reveal connection on the reveal side and an offset air flow direction perpendicular to the building wall, allowing for a shallow module depth that minimally weakens the wall while maintaining visual aesthetics, using materials like plastic, sheet metal, or wood fibers, and incorporating features such as bracing elements and insulation holders.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a reveal duct is integrated into the outer layer of the wall (especially clinker brick), then the aesthetic appearance is improved, but the structural strength of the wall is weakened
Solution Approach 1:
The ventilation duct module changes the integration approach from lateral integration within the outer wall layer to depth-based integration within the insulation layer. The module extends in the depth direction of the wall (from outer surface inward) rather than requiring lateral space within the outer layer, allowing aesthetic integration without compromising structural strength.
Solution Approach 2:
The ventilation duct module is nested within the insulation layer of the wall structure, utilizing the existing space between the outer and inner wall layers. This nesting approach allows the duct to be integrated into the wall without requiring removal or tapering of the outer clinker brick layer, thus preserving structural integrity while achieving aesthetic integration.
2Productivity
If the outer layer of the wall is tapered to accommodate the reveal channel, then the ventilation function is improved, but the structural stability is weakened
Solution Approach 1:
The ventilation function is achieved by extending the duct in the depth direction within the insulation layer rather than tapering the outer wall layer laterally. This dimensional change allows sufficient duct volume for ventilation while avoiding any tapering that would compromise the structural stability of the outer clinker brick layer.
Solution Approach 2:
The wall structure is segmented into distinct functional layers: the outer clinker brick layer for structural stability and aesthetics, the insulation layer for thermal insulation and duct integration, and the inner wall layer for interior finishing. This segmentation allows each layer to fulfill its primary function without compromising the others.
3Strength
If a shallow module depth is used, then the structural weakening is reduced, but the air flow guidance becomes more complex
Solution Approach 1:
The flow duct within the module incorporates curved transitions and angled sections to guide air flow from the reveal connection to the duct connection. These curved pathways efficiently navigate the shallow depth of the module while maintaining smooth air flow, reducing turbulence and pressure losses despite the limited space.
Solution Approach 2:
The air flow guidance utilizes the depth direction of the module efficiently, with the flow duct extending from the reveal side toward the interior side while incorporating vertical and horizontal components. This three-dimensional routing approach achieves effective air guidance within the shallow module depth without excessive complexity.
