Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single air outlet channel is used, then the device structure is simple, but it cannot provide optimized airflow for different operating modes (cooling, heating, purification)
Solution Approach 1:
The air outlet channel is segmented into multiple independent channels (first air outlet channel, second air outlet channel, third air outlet channel), each serving different functions. This segmentation allows optimized airflow delivery for different operating modes without requiring a completely different device structure, resolving the contradiction between adaptability and structural simplicity.
Solution Approach 2:
The air outlet channel configuration is made dynamic through the movable door mechanism that can adjust the opening degrees of different air outlet channels based on operating mode. This dynamic adjustment enables the system to adapt to different cooling, heating, and purification requirements while maintaining a relatively simple overall structure.
2Productivity
If fixed air outlet configuration is used, then the device structure is simple, but airflow rate and velocity cannot be optimized for different functions
Solution Approach 1:
The air outlet channel configuration is made dynamic through the movable door mechanism that can adjust the opening degrees of different air outlet channels based on operating mode. This dynamic adjustment enables the system to adapt to different cooling, heating, and purification requirements while maintaining a relatively simple overall structure.
Solution Approach 2:
Different air outlet channels are designed with different local characteristics (directional vs. non-directional airflow, different opening degrees) to optimize airflow delivery for specific functions. The movable door mechanism allows local adjustment of each channel's opening degree, enabling optimized airflow rate and velocity for each operating mode without complicating the overall device structure.
3Temperature
If all airflow is directed to user through first air outlet, then cooling effect is maximized, but air purification function is compromised
Solution Approach 1:
The air outlet system is segmented into multiple independent channels, allowing purified air to be directed through different pathways. The third air outlet channel specifically handles purified air discharge, while the first channel provides directional cooling airflow to the user. This segmentation enables both cooling and purification functions to operate simultaneously without compromising either function.
Solution Approach 2:
Different air outlet channels are designed with different local characteristics (directional vs. non-directional airflow, different opening degrees) to optimize airflow delivery for specific functions. The movable door mechanism allows local adjustment of each channel's opening degree, enabling optimized airflow rate and velocity for each operating mode without complicating the overall device structure.
4Speed
If air leakage channel opening is reduced, then directional airflow to user is improved, but overall airflow rate decreases
Solution Approach 1:
The air outlet system is segmented into multiple independent channels, allowing purified air to be directed through different pathways. The third air outlet channel specifically handles purified air discharge, while the first channel provides directional cooling airflow to the user. This segmentation enables both cooling and purification functions to operate simultaneously without compromising either function.
Solution Approach 2:
The air outlet channel configuration is made dynamic through the movable door mechanism that can adjust the opening degrees of different air outlet channels based on operating mode. This dynamic adjustment enables the system to adapt to different cooling, heating, and purification requirements while maintaining a relatively simple overall structure.
