Rattle Drum Various voiced is an innovative redesign of the traditional rattle drum toy, created by designer Qiu Liwei and team, that introduces multiple sound variations through advanced structural engineering and contemporary manufacturing techniques. This groundbreaking design, which earned recognition with an Iron A' Design Award in the Toys, Games and Hobby Products Design category, represents a significant evolution in children's musical toys by incorporating three-dimensional carving technology on the inner drum walls to create diverse acoustic textures. The product, measuring 180mm×65mm×13mm and 160mm×85mm×13mm, is crafted from environmentally conscious composite bamboo board, demonstrating a commitment to sustainable material choices while maintaining durability and acoustic performance. The design's primary innovation lies in its ability to produce various distinct sounds through different textured surfaces, effectively stimulating children's auditory development and enhancing interactive play experiences. This thoughtful approach to traditional toy redesign emerged from extensive research and development conducted in 2017, addressing the contemporary need for educational toys that combine sensory stimulation with sustainable manufacturing practices. The design successfully overcomes the technical challenge of creating distinctly different sound patterns through precise surface texturing, achieved through rigorous prototyping and testing phases, while maintaining manufacturing efficiency through 3D carving molding techniques.
