The project is designed for Nedfon, the industry leader in the ventilation system. Nedfon would like to launch a series of products as innovative to break into the market. Using transparent material would be a bold attempt in household appliances.

The first scheme uses a horizontal groove to divide and decrease the visual volume, and vertical ribs to build a type of texture; then, a metal tag with the logo as the focal point to connect the top and the bottom.

The second scheme uses two-level nets to intersect with each other which forms delicate lights and shadows and makes the whole panel look like crystals.

The third scheme uses lines to build concave-convex surfaces interlaced with each other and slotting surfaces between concave-convex surfaces for exhausting air.
