Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the valve is tilted to control air flow, then the flow capacity can be adjusted, but the valve occupies large space and causes flow direction turbulence
Solution Approach 1:
The single tilted valve blade is segmented into multiple independent gate blades (at least three) arranged radially around a central axis. Each blade can be independently controlled to move between open and closed positions, eliminating the need for large tilting angles while maintaining flow control capability and reducing space occupation.
Solution Approach 2:
The gate blades are designed with dynamic movement capability, allowing them to rotate independently around the central axis between fully open and fully closed positions. This dynamic configuration enables precise flow control without the space-consuming tilting mechanism of conventional valves.
2Productivity
If the valve is tilted to adjust flow capacity, then the opening area can be controlled, but the tilted valve gate causes flow direction turbulence and obstruction
Solution Approach 1:
The valve is divided into multiple independent gate blades that can be positioned separately. When opened, these blades create a circular or annular opening that guides airflow smoothly along the duct axis, preventing the turbulence and directional changes caused by tilted single-blade valves.
Solution Approach 2:
Instead of tilting the valve blade at an angle to the duct axis (conventional approach), the gate blades are arranged radially perpendicular to the duct axis and rotate in a plane parallel to the duct cross-section. This inverted configuration maintains airflow directionality and eliminates turbulence.
3Reliability
If the air duct and valve are tightly fitted, then the sealing is improved, but the valve cannot be opened and closed freely and may be easily broken
Solution Approach 1:
The sealing function is extracted from the valve blades themselves and assigned to a separate sealing ring that fits into the air duct. This sealing ring can be tightly fitted to ensure good sealing when the gate is closed, while the valve blades remain independent and can be freely operated without being constrained by the duct walls.
Solution Approach 2:
The sealing system is segmented into a separate sealing ring component rather than being integrated into the valve structure. This allows the sealing ring to maintain tight contact with the duct for reliable sealing, while the gate blades can move freely to open and close the valve without mechanical interference.
4Ease of operation
If the valve can open and close easily, then the operation is simplified, but the sealing is affected resulting in back flow
Solution Approach 1:
The sealing function is separated from the actuation mechanism. The sealing ring is positioned to contact the duct wall when the gate is in the closed position, ensuring reliable sealing and preventing backflow. The gate blades can be easily operated to move between open and closed positions without compromising this sealing arrangement.
5Measurement precision
If detectors are installed in the air duct to measure wind pressure and wind speed, then the measurement capability is provided, but the unstable air flow causes inaccurate data
Solution Approach 1:
The gate blades are positioned to create a stable, laminar airflow pattern before the air reaches the detector installation location. By controlling the gate blades to open fully or close completely rather than tilting at intermediate angles, the airflow remains stable and predictable, providing accurate measurement data from the detectors.

AI summary
The present invention discloses an intelligent wind gate device with diversion structure for pressure detection. It primarily improves upon conventional wind gate device, which cannot automatically control, have interlinked internal blades that are prone to damage and cannot be replaced individually, and whose interlinked blades make it difficult to achieve a tight seal when opening and closing. This invention proposes a wind gate device that ensures stable exhaust when opened, high sealing performance when closed, and features a deflector component for pressure measurement. It can more accurately measure functions such as air pressure, airflow rate, air volume, temperature, humidity, PH levels, and gas concentration within the air duct.
