Crutches are a basic requirement of any orthopedically handicapped person. over the last fifty years, there has not been major improvements in terms of its design. there are some japanese and german models but they are very sophisticated and hence are very costly. developing countries like india requires cost effective designs with added features. based on our interaction with people using crutches, we found that they have very bad experiences with crutches. the inefficient crutches presently available, restricts their day to day life within a boundary. for example- they cannot walk for more than 1 km daily with these crutches as it creates pain in their underarm and sometimes it causes injuries. crossing the road becomes a herculean task for them. it usually takes around 10 minutes to cross a road. since they do not have options, they are bound to use presently available products. the best way to empower orthopedically handicapped is to empower them with a crutch which can assist them in all day to day activities and do not create a problem for them. we have developed a cost effective model of crutch with desired features required by the orthopedically handicapped. the major improvements have been done in the field of reducing injuries, avoidance of sudden failure, and assistance during road crossing and empowering them with certain simple embedded gadgets to assist them during night and on slippery surfaces like toilet and bathrooms. the process started with defining the ‘mission statement’ and preparing the ‘buyer’s utility map’. we then interviewed 12 people who uses crutches and 3 orthopaedist and find out the needs of the users and prepared ‘need statement’ accordingly. we ranked the needs as per the priority of users. thereafter, we prepared the ‘house of quality’ to establish the interrelationship between needs and different metrics. we then ‘benchmarked’ the different features as per the presently available products in the market. after benchmarking, we prepared five concepts and designed them using ‘autodesk inventor’ software. we again reached to the users for selection of best concept amongst those five developed. in this way, we selected the concept after recombination according to inputs from users. at the end, we developed a ‘work like’ prototype of our concept. due to our limitation, we could put all the features of the concept into the prototype but we are working on that. during our interaction with the customers, we found overwhelming response from users. most of them were more than happy to buy it. as all the improvements made are very simple, hence the expected price of the product is very similar to that of the presently available crutches in the market.
