The design inspiration for the product comes from the moon phase change. The combination of static aesthetics and balance criteria makes the combination of rings fascinating and unique. The theme of the design is to explore how to give intelligent products a proportionally balanced form language and make them into devices with both functions and modern aesthetics. The cooling fins are designed with a fine texture of dip Angle to increase the cooling area and light and shadow detail of the product. In ancient Chinese poetry culture, there are not only "people have joys and sorrows, and the moon has its waxing and waning", but also "raise a glass to invite the moon, forming three people to the shadow". The change of the moon has inspired the Romantic feelings of the Chinese people and has also become an important image for us to place feelings of care. As a product designer, WE want Crescent to convey humane care with unique cultural meaning. Compared to similar products, Crescent has a simple and clean shape and simple materials. It has fewer parts, is lighter and therefore easier to repair and is more environmentally friendly. We realize that IoT devices are already everywhere, but the balance between innovation and mass production is rarely addressed. Inspired by the changing phases of the moon, Crescent's design theme explores how to give a proportionally balanced form language to smart products that are both functional and aesthetically modern. Crescent represents our strong focus on product-based visual experience, as well as our future-oriented design awareness. Crescent features low power consumption and strong compatibility. As a Bluetooth gateway, the corresponding positioning system can be connected to various Bluetooth devices. AOA directional function with 5.1 protocol makes the positioning accuracy error of the product less than 50cm, and its high accuracy and compatibility make it have obvious advantages in performance.
