Fogging and moisture accumulation on the interior side of vehicle windshields continue to affect driving visibility despite the development of various defogging and climate-control approaches. While previous studies have mainly addressed the problem through HVAC optimization, airflow management, or intelligent monitoring systems, direct moisture handling at the interior glass surface remains less explored. In response to this gap, the present study proposes an interior windshield moisture management model based on vapor-assisted wiping. The model integrates a water reservoir and vapor generation unit, a guided vapor delivery pathway, and a regulated wiping interface that includes a porous moisture-distribution structure. These components work together to control vapor transfer before it reaches the windshield, allowing the wiping action to operate with a moderated moisture layer rather than uncontrolled vapor flow. The proposed system architecture explains how moisture generation, routing, and surface interaction are coordinated to support stable visibility inside the vehicle cabin. This model offers an alternative approach that complements existing defogging strategies and may contribute in future work to the development and evaluation of more effective interior windshield visibility enhancement systems.
