Solution Approach 1:

The emanating surface is configured as a three-dimensional structure with inner and outer surfaces, allowing air flow to access the emanating liquid from multiple spatial dimensions simultaneously. The inner surface is positioned to receive air flow from the pump, while the outer surface is exposed to ambient air, creating multi-directional evaporation pathways that overcome the limitations of compact packaging.
