The ‘Kranium’ is a bike helmet that incorporates a corrugated design to enhance impact absorption. Core77 reports that Anirudha Surabhi essentially designed it from scratch, basing the liner on the cartilage structure of a woodpecker so it mimics the qualities of the bird’s natural shock absorber.
The helmet uses a unique paper board, called the Dual Density Honey Comb Board or D2. This is broken down into ribs, which are strategically placed to absorb three times the amount of impact as a standard Expanded Polystyrene (EPS) helmet. Kranium is made from recycled paper to reduce its carbon footprint and is 15% lighter than the EPS liner. The video below shows the helmet’s journey from a sketch to production, showcasing its development after it was conceptualised at the Royal College Of Art in London:
