The use of magnetic elements between the screen and air intake shutter allows for simplified control of the ventilation device, improving aesthetics and reducing costs by eliminating the need for visible cables and enabling control in multiple screen positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a cable system is used to control the ventilation device, then the control functionality is achieved, but the aesthetic appearance deteriorates and costs increase
Solution Approach 1:
The patent removes the cable system from the visible area by extracting it from the space between the screen and window. The control functionality is maintained through magnetic coupling that eliminates the need for visible mechanical connections, thus preserving aesthetics while maintaining operational capability.
Solution Approach 2:
The patent replaces the mechanical cable-based control system with a magnetic field-based control system. The magnetic elements transmit control signals without physical contact, eliminating the need for visible cables and mechanical linkages while maintaining the ventilation control functionality.
2Ease of operation
If a cable system is used to control the ventilation device, then the control functionality is achieved, but the manufacturing cost increases
Solution Approach 1:
The patent replaces the complex mechanical cable system with simpler magnetic elements and a control unit. This substitution reduces manufacturing complexity and material costs while maintaining the ventilation control functionality through magnetic coupling and electronic control.
3Ease of operation
If the cable system controls the shutter through screen slats, then the ventilation control is achieved, but the screen functionality deteriorates by blocking light
Solution Approach 1:
The patent extracts the control mechanism from the screen slats themselves, using magnetic coupling between the screen assembly and ventilation device instead. This allows the screen to remain in its ventilation position without requiring force transmission through the slats, preserving both light transmission and ventilation control functionality.
4Ease of operation
If the cable system is used, then the ventilation device can be controlled, but the device complexity increases
Solution Approach 1:
The patent replaces the complex mechanical cable transmission system with a magnetic field-based control system. The magnetic elements and control unit create a simpler system that achieves ventilation control without the complexity of mechanical linkages, pulleys, and force transmission mechanisms.
