Solution Overview
Problem
Existing ventilation networks for buildings, particularly single and multi-family houses, face challenges in being economical to assemble and having high functionality, especially when integrated with visible roof trusses, as they often require complex and costly installation processes.
Innovation Solution
A construction kit comprising concrete and plastic pipe-concrete elements, including fiber concrete blocks, corrugated plastic tubes, and coupling elements, designed for easy assembly and integration with visible roof trusses, utilizing casting methods and fiber-reinforced concrete to create a modular and efficient ventilation network system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional ventilation networks are assembled in buildings with visible roof trusses, then the ventilation function is achieved, but the assembly process becomes complex and costly
Solution Approach 1:
The ventilation network is divided into modular components: concrete elements with integrated plastic pipes, coupling elements, and adaptors. These standardized modules can be independently manufactured and assembled on-site, reducing installation complexity and cost while maintaining functionality in buildings with visible roof trusses
Solution Approach 2:
The coupling elements and adaptors are designed with universal connection capabilities that work with both concrete elements and flexible pipes. The system can adapt to different building configurations including visible roof trusses through wall adaptors and ceiling adaptors, making it universally applicable without requiring complex custom installations
2Device complexity
If plastic pipes are embedded in concrete blocks, then the ventilation network structure is simplified, but the manufacturing process becomes more complex
Solution Approach 1:
Plastic pipes are pre-positioned and embedded in concrete blocks during the manufacturing process rather than installing them on-site. The concrete elements are produced with integrated pipe connections already formed, so that when assembled, the ventilation network has a simplified structure without requiring complex on-site pipe embedding operations
3Adaptability or versatility
If a modular system with multiple component types is used, then the ventilation network becomes more adaptable to different building configurations, but the number of different parts increases
Solution Approach 1:
The coupling elements are designed with universal connection capabilities that work with multiple component types. The same coupling element can connect concrete elements to flexible pipes, or adaptors to pipes, reducing the variety of unique parts needed while maintaining high adaptability to different building configurations including visible roof trusses

AI summary
Described is a modular system for constructing a ventilation network for a building, preferably a single-family or multi-family dwelling, comprising the following components: concrete elements (1, 2, 3, 4, 7), plastic pipe-concrete elements (5, 6), cuttable flexible pipe (9), and coupling elements. One application is the construction of an exposed roof truss with a ventilation network, wherein a plastic pipe-concrete element (wall vertical pipe, 6) and a concrete element (wall valve adapter, 7) connected to it are installed in a building partition wall (22) as a wall penetration in the exposed roof truss.
