First, we did the market survey and concluded that most of the bike riders feel awkward to carry a bulky and large helmet while traveling. so, many designers all around the world are trying to find multiple solutions for this problem; we got an idea to develop a foldable helmet. studies have shown that wearing a helmet can reduce the risk of head and brain injury by approximately 85%. with an increasing population of bikers in trafficked areas, it is becoming more critical to protect riders from possible serious injury. in addition to complying with legislation that requires the use of helmets, it is also essential for a helmet to appeal to the user’s wants. helmets are bulky and as a result, discourage their use because they cannot be easily handled or stored in a bag pocket or desk drawer. a foldable solution could expand the market for helmets to users who are looking for an easy handling option and would improve the percentage of helmet wearing bikers on the road.
