Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single blower fan is used in conventional purification devices, then the device structure is simple, but the airflow distribution and purification effectiveness are insufficient
Solution Approach 1:
The patent divides the single blower fan into multiple blower fans (first blower fan and second blower fan), each responsible for different airflow directions and regions. This segmentation enables better airflow distribution throughout the vehicle interior while maintaining independent control of each fan unit.
Solution Approach 2:
The multiple blower fans serve multiple functions: they create different airflow patterns, work in conjunction with the generation device for enhanced purification, and can be controlled independently based on vehicle conditions. This multi-functionality improves overall purification effectiveness without requiring entirely separate systems.
2Productivity
If conventional purification methods are used, then the device is simple to manufacture, but air purification effectiveness is inadequate
Solution Approach 1:
The patent combines the generation device (producing charged water particles or ions) with multiple blower fans in a single integrated system. This merging allows the purification and airflow generation functions to work synergistically, improving air purification effectiveness while avoiding the need for separate manufacturing processes.
Solution Approach 2:
The patent introduces charged water particles or ions as an intermediary substance that enhances the purification process. These particles act as mediators between the generation device and the air, improving purification effectiveness through electrostatic attraction and chemical reactions without requiring complex mechanical filtration systems.
3Adaptability or versatility
If fixed airflow settings are used, then the control system is simple, but the device cannot adapt to different vehicle usage conditions
Solution Approach 1:
The patent implements dynamic control of the blower fans, allowing their rotational speeds to be adjusted based on vehicle usage conditions. The control unit monitors vehicle state (such as door opening/closing, engine status) and dynamically modifies fan operation to optimize purification effectiveness for different scenarios.
Solution Approach 2:
The control system incorporates feedback mechanisms that monitor vehicle usage conditions and adjust the blower fan operations accordingly. This feedback loop enables the system to adapt to changing environmental conditions and vehicle states, improving versatility while maintaining manageable control system complexity through automated decision-making algorithms.
