Solution Overview
Problem
Conventional air ventilation systems are energy-inefficient, noisy, and require significant physical modifications to homes, emitting excessive heat energy and producing unwanted noise, which are nuisances for homeowners.
Innovation Solution
An air flow control system comprising a damper housing, damper assembly, ventilation cap, and control module that directs furnace air either to a cooling coil for cooling or to an attic for heat release, utilizing existing furnace blower to conserve energy and reduce noise, without requiring extensive installation modifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If conventional air conditioning systems are used to cool buildings, then cooling function is provided, but excessive energy is consumed and significant heat is emitted as waste
Solution Approach 1:
The patent captures the waste heat emitted by the air conditioning system and redirects it through a mirror assembly to melt snow on the roof. This converts the harmful waste heat into a beneficial function for snow removal, thereby reducing energy loss while maintaining cooling capability.
Solution Approach 2:
The air conditioning system is enhanced with additional functionality by integrating a snow melting feature. The same system that provides cooling now also serves to melt snow on the roof, making the system multi-functional and reducing the need for separate snow removal equipment.
2Temperature
If air conditioning units are installed in homes, then cooling is provided, but loud noise is generated which disturbs homeowners
Solution Approach 1:
The noisy components of the air conditioning system, particularly the compressor, are relocated from inside the home to an external position on the roof. This extracts the noise source from the living space, allowing the cooling function to remain while the harmful noise is removed from the indoor environment.
3Temperature
If new ventilation systems are added to homes, then cooling capability is improved, but physical modifications to the home structure are required
Solution Approach 1:
The snow melting function is integrated with the existing air conditioning system rather than being implemented as a separate system. The mirror assembly uses the same compressor and refrigerant cycle, merging two functions into one system and avoiding the need for separate installation infrastructure.
Solution Approach 2:
The air conditioning system is enhanced with additional functionality by integrating a snow melting feature. The same system that provides cooling now also serves to melt snow on the roof, making the system multi-functional and reducing the need for separate snow removal equipment.
4Temperature
If air conditioning compressors operate, then cooling is produced, but damaging noises such as humming and clanking occur when damaged
Solution Approach 1:
The noisy components of the air conditioning system, particularly the compressor, are relocated from inside the home to an external position on the roof. This extracts the noise source from the living space, allowing the cooling function to remain while the harmful noise is removed from the indoor environment.

AI summary
An air ventilation system. The system may comprise an air flow control box and a control module, wherein the air flow control box may comprise: a damper housing, ventilation cap, damper assembly, control arms, and damper motor. The damper housing may define a passage traversing from a proximal end to a distal end of the damper housing and may comprise a ventilation opening. The ventilation cap may be hingedly connected to the damper housing for selective movement between an open position and a closed position. The damper assembly may be in covering relation with the passage and may comprise damper blades that pivot together for selective movement between an open position and a closed position. The damper motor may actuate the selective movement of the ventilation cap and the plurality of damper blades via the control arms. The control module may actuate the damper motor of the air flow control box.
