Padman learns design thinking through solving problems in innovative ways. He sees his wife struggling while chopping onions and creates a drumstick knife chopper toy to solve it. His wife has difficulty riding a bicycle with one seat, so he designs a second seat from wood. He discovers women's reluctance to buy sanitary pads due to cost and creates his own prototype pad made of cotton and muslin cloth to make pads affordable. Through feedback and iterations, he develops an efficient pad that costs just Rs. 2. He analyzes the total, serviceable, and obtainable market for selling low-cost sanitary pads in India to create jobs and expand his customer base.
