Engineering Contradiction Analysis
1Productivity
If traditional independent pipelines are used for HVAC systems, then air transport function is achieved, but construction time and space requirements increase
Solution Approach 1:
The patent combines the HVAC ventilation function with the building frame structure by integrating ventilation spaces and ducts directly into the hollow columns and beams. This merging eliminates the need for separate independent pipelines, allowing the structural framework to simultaneously provide both support and ventilation functions, thereby reducing construction time and eliminating redundant installation steps
Solution Approach 2:
The building frame components (columns and beams) are designed to serve multiple functions: structural support and HVAC ventilation. The hollow sections of the columns and beams contain ventilation spaces and ducts, making the structural elements universal components that fulfill both mechanical support and air transport requirements, thus improving construction efficiency by reducing the number of separate systems needed
2Ease of operation
If separate HVAC pipelines are installed, then ventilation function is provided, but construction complexity and space requirements increase
Solution Approach 1:
The ventilation system is merged with the building frame structure, where hollow columns and beams contain integrated ventilation spaces and ducts. This combination simplifies the overall system by eliminating separate pipeline installations, reducing construction complexity, and making the HVAC system inherently part of the structural framework rather than an add-on component
Solution Approach 2:
The patent extracts the ventilation function from separate pipelines and integrates it directly into the building frame components. By taking out the need for independent HVAC piping and embedding the ventilation capability within the columns and beams themselves, the system reduces operational complexity and simplifies installation procedures

AI summary
The present invention provides a building frame structure with both support and ventilation functions, the building frame structure contains at least one starting column and multiple main beams, the main beams are connected with the starting column, and top of the starting column is connected to a fan. The starting column is a hollow cylinder, and there are four thin hollow columns in the starting column. The main beams are hollow structures, and a reinforcing wall is arranged inside the main beams, the reinforcing wall is connected with inner walls of the main beam to form multiple ventilation ducts. When the frame structure is installed, air sent by the fan flows to the ventilation ducts of the main beams through the ventilation spaces of the thin hollow columns, the second air guide holes, and the first air guide holes, and then sends the air to various places in the building.
