recent industrial design RCA graduate anirudha rao has developed 'kranium', a solution for effective
cycling protection, exhibited during london design week 2010 at designersblock.

through his research, rao found that expanded polystyrene has been used to create bike helmets for the last
few decades, and there has been little in terms of safety over the years. on average, helmets protect your head
only 16 percent of the time during a crash, giving us the false implication of safety. polystyrene does little to
absorb impact energy. instead it distributes it over the head. typically in helmet design, more emphasis is given
to styling and aerodynamics. however, while cycling through a busy city an average speed of 12 mph,
safety definitely becomes more important than aerodynamics.

so, rao asked himself, 'why is this unsustainable, non-recyclable material, largely focused on aesthetics being
pushed into our lives to promote safety?'

'kranium' is his solution. it looks at creating a lightweight outdoor sports activity helmet that will change
the market through improved safety, recyclability and overall design - its structure has been developed to absorb
impact energy. the ribs have been designed to accommodate movement in some places, however remaining
perfectly rigid in other areas. during a crash, the force peak of the impact is absorbed by the ribs tending to flex
and de-flex. the remaining amount of energy is then absorbed by the crumpling nature of the corrugated ribs.
when tested against british (EN 1078) standards at the imperial college, it was calculated that 'kranium' absorbs
four times the amount of impact energy when compared to regular cycling helmets. this means that during a crash,
lesser amounts of energy go into your head, making it a safer option than those already on the market.






it has also been concluded that 'kranium' lasts more than one impact. during the testing phase, the same helmet
was tested five consecutive times, still proving to pass the standard. however, polystyrene helmets were rendered
useless after a single impact.

another issue that came up during rao's research was that polystyrene helmets today, never properly fit the user's head.
additional straps and levers are provided to grip the head, but they never tend to provide a perfect fit, hence when
a crash occurs, the helmet slides out of its position upon impact and does very little to protect the user's head.
due to the structural nature of 'kranium', bespoke custom made helmets can be manufactured by scanning one's head.
through generated coordinates, templates can then be produced and assembled together, making it a completely
customizable piece of head protection, where every single element such as shape, fit, color etc., can be tailored to
the user. the individual's head would be scanned and a file would remain in a system, so that upon damaging the helmet,
a brand new one could be could be reproduced for a fraction of the price. this encourages one to change the helmet
when it needs to be changed without spending an exorbitant amount of money.

'kranium' is lighter and its custom sizing makes it more comfortable, bringing together form and function in a
cost-effective product made from eco-friendly materials. it also has the potential to play a part in the future of
bike rentals, which are becoming more eminent in cities world wide. a cheap helmet, which can be dispensed
through a vending machine, could be the answer for the future of bike rental safety.
