Solution Overview
Problem
Existing vehicle humidity controlling systems face challenges in efficiently performing dehumidification and regeneration processes due to limitations in air flow rate control using a single ventilation fan, leading to inefficiencies and increased system size when dual fans are used.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a single ventilation fan is used to control air flow rate, then the system size is reduced, but the ability to efficiently perform both dehumidification and regeneration processes is compromised
Solution Approach 1:
The patent applies dynamics by making the air flow rate adjustable through fan speed control and valve positioning. The single ventilation fan's output is dynamically adjusted, and the split ratio between dehumidification and regeneration paths is dynamically controlled via valves, allowing the system to adapt flow rates to different process requirements without increasing system size
Solution Approach 2:
The patent changes parameters by adjusting the fan's rotation speed and the opening degree of valves to optimize air flow rate for different modes. By varying these parameters, the system achieves appropriate flow rates for both dehumidification (higher flow) and regeneration (lower flow) processes using the same single fan
2Productivity
If two ventilation fans are installed for each process, then the air flow rate control for dehumidification and regeneration is improved, but the system size increases
Solution Approach 1:
The patent applies universality by designing a single ventilation fan that serves multiple functions - controlling air flow for both dehumidification and regeneration processes. The fan is paired with a split flow path and valves, allowing one fan to replace what would traditionally require two separate fans, thus reducing system size while maintaining control capability
Solution Approach 2:
The patent segments the air flow control by dividing the single fan's output into two separate paths using valves. This segmentation allows independent control of flow rates to the dehumidification and regeneration processes, achieving the functionality of multiple fans through a single unified system

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system efficiently performs dehumidification and regeneration processes by adjusting airflow through the use of a single ventilation fan, enhancing moisture adsorption and separation efficiencies while maintaining a compact design.
Implementation Method 1
a layer containing a functional material (moisture absorbing layer) on surfaces of the partition walls that adsorbs water vapor (moisture) and the like
Implementation Method 2
the heater element can be heated to regenerate the functional material-containing layer by releasing the moisture adsorbed in the functional material-containing layer
