Three students from the IVE Electrical Engineering Higher Diploma programme participated in the HongKongTechathon+2025 competition with their project “Eco-Sustainable Motor Design Using Sand to Perform Soundproof", competing against a total of 380 teams worldwide, including mainland China, the United States, Malaysia, Thailand, Singapore, Taiwan, Macau, Australia, Portugal, and Brazil. The students excelled in the competition and secured the bronze medal in the "Sustainable Development and Environment, Social and Governance" for local university student category.
The award-winning project, inspired by the Engineering discipline's solar-powered car SOPHIE, utilized a material consisting of sand mixed with resin for effective sound insulation in the car engine. Compared to traditional soundproofing materials, the sand-based material is lighter in weight and can reduce noise by about 5-10 decibels. This material is easy to shape and apply to surfaces, solidifying quickly under sunlight to simplify the application process. The students plan to further research this material and potentially implement this the technology in small appliances such as vacuum cleaners or drills.
Among the three award-winning students, one is local, while the two are first-year students who enrolled the Higher Diploma through the Vocational Professionals Admission Scheme (VPAS). Despite coming from different regions of China and Hong Kong, these students, united by a shared belief and goal, effectively applied their knowledge, achieved success in the competition, secured startup funding, and took an important step towards their future development.
