At the beginning of the project, we conducted research and discussion on how Haitian can find product differentiation in line with the trend to reflect the brand value of Haitian. Starting from understanding the market, products and existing characteristics, we have determined that the product shape is square, the color is mainly dark, the simple assembly and ease of operation are the breakthrough, the use of simple buckle to open the upper cover and other ways to open the differentiation with similar products, combined with Haitian brand rigorous and calm tone, with design to highlight the brand value of the product.
