Krell is a benchmark in the measurement industry. It has rich experience and understanding of the needs of the measurement and health management industry. With its rich sensor design capabilities, it provides customized sensors and manufacturing processes for users everywhere. The baby scale designed by Trojan Design Company is a market-oriented product based on consumer demand, which reflects the designer's attention to the details of users' lives. Considering the particularity of the product itself, the designer first started with ergonomics and adopted a left and right bulge design on both sides of the scale to ensure the comfort of the baby. Each line on the scale body has functional significance. While realizing decoration, the function of the scale body is divided. The raised area divided by the left and right lines is made of frosted material, which strengthens the stability of the measurement result by stabilizing the baby. The lines on the side are interspersed with the raised lines to form the control panel area. The baby scale has become a typical example of market-oriented design with its stable shape, soft lines and reasonable and clever functional layout.
