According to Mayank Pareek, who worked on the project under the guidance of Dr Sujatha Srinivasan from the department of mechanical engineering, these can be used by individuals with cerebral palsy and those affected by trauma as well. The length adjustability from the knee joint to the foot and the thigh to the knee joint was brought about by using a telescopic linkage, he added.
"We can also bring down the production time with this. Normally, people who visit the camps are asked to come back for being fitted with the braces the next day. However, we have developed them so that they are available in small, medium and large sizes which can be adjusted within just 35 minutes. If a child finds he has outgrown the braces, they can be adjusted to the right size at home instead of coming again for a new fitting," Pareek said.
While the cost of production for the existing style of calipers or orthoses was Rs 1,100 for the NGO, Pareek said that the adjustment would add only a sum of Rs 50 to the manufacturing cost. The entire philosophy document on how to manufacture product based on the design on a large scale has been handed over to the BMVSS.
