Ruilang shares his journey from designing a one-handed nail clipper for a teenager with a disability to creating an underwater robot for aquaculture safety. He reveals how listening to real human struggles—not genius ideas—fuels true innovation. Through personal stories and examples like Anker’s success with one-star reviews, he presents a powerful three-step framework for turning everyday frustrations into world-changing solutions. Ruilang is a compassionate innovator and engineer dedicated to solving real-world problems through human-centered design. His design journey began with creating a one-handed nail clipper for people with disabilities and expanded to developing an underwater robot for the aquaculture industry, which won first prize at an international invention expo in Germany and was a finalist in the Conrad Innovation Challenge. He firmly believes in the "Listen-Empathize-Create" innovation model, excelling at identifying pain points from everyday conversations and user feedback, then transforming these insights into practical technological solutions. His work embodies the perfect integration of technology and humanism, always aiming to improve people's quality of life.
