The Challenge

Standardization has been the operating principle of interchangeability of parts in human-made manufacturing since the Industrial Revolution. However, standardization in carpet tile design and color made matching of replacement tiles with pre-existing carpet extremely difficult. When traditional broadloom carpet becomes dirty or damaged, entire rolls of carpet are replaced and carted off to landfills, resulting in increased waste, as even tiles in good condition had to be replaced for aesthetic reasons. Additionally, later in the lifetime of the carpet, it is challenging to find a replacement tile that seamlessly blends in.

Innovation Details

i2® carpet tiles feature random patterns and gradations of colors that allow the tiles to be installed non-directionally. No matter how the tiles are arranged on the floor, the colors and patterns work together to form a cohesive design, similar to a forest floor. i2 carpet tiles can be replaced individually and many of the components can be recycled, resulting in significant reductions in waste and cost. The intentional color variations eliminate common concerns over dye lots, meaning that consumers no longer need to purchase large quantities of “attic stock” in order to ensure matching replacement tiles. The color variations also make it difficult to perceive small stains and soil.

Biological Model

The forest floor has a wide variety of colors and textures, and features shapes that repeat but in infinitely varied arrangements. Still, humans perceive the forest floor––with leaves, twigs, rocks, and more––to have a cohesive and even potentially pleasing visual effect. The varied appearance also allows a wide variety of creatures to exist on the the forest floor without being easily detected by predators.
