Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If large outlet openings are used to ensure required deflection angle, then airflow deflection capability is improved, but device compactness and aesthetic appearance deteriorate
Solution Approach 1:
The patent employs dynamically adjustable louvers that can change their angle and position to achieve different airflow deflection angles. This allows the device to maintain a compact outlet opening while still providing the required deflection capability through active adjustment rather than fixed large openings.
Solution Approach 2:
The invention changes the parameters of the louvers (angle, position, orientation) to optimize airflow deflection. By adjusting these parameters, the system achieves effective airflow control with a compact outlet opening, resolving the contradiction between deflection capability and device size.
2Adaptability or versatility
If large outlet openings are used to ensure required deflection angle, then airflow deflection capability is improved, but integration into instrument panel becomes difficult
Solution Approach 1:
The dynamically adjustable louvers allow the ventilation device to achieve required airflow deflection within a compact shape that can be integrated into the instrument panel. The adjustability compensates for the reduced size, maintaining functionality while improving integration capability.
3Volume of moving object
If complex systems with many components are used to reduce outlet opening size, then device compactness is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The louvers in the invention serve multiple functions: they control airflow direction, adjust deflection angles, and can be integrated into a compact structure. This multi-functionality reduces the need for additional components, maintaining compactness while avoiding increased complexity.
Solution Approach 2:
By achieving compactness through parameter optimization of existing components (louver geometry, angle, position) rather than adding more components, the invention reduces device complexity while maintaining compact size.
