This product is based on the small-sized population as the background, aiming at the inconvenience caused by the lack of space for the small-sized population, the existing projector process is cumbersome, the form is single, and the attention to the small-sized rental space is insufficient, and the design scheme is proposed. Through the rotatable structure and one-key focusing of the picture, the product solves the burden of complicated space use and operation, so that it can be used more smoothly. The minimalist design reduces the sense of existence of the equipment, avoids becoming the visual center, and improves the convenience of use. This product is designed with residents of small living spaces in mind. It addresses the inconveniences caused by limited space, the cumbersome setup processes of existing projectors, and their lack of versatility-all of which fail to adequately cater to the needs of small rental units. Featuring a rotatable structure and one-touch image focusing, the product alleviates the burdens of space constraints and cumbersome operation, enabling a smoother user experience. Its minimalist design minimizes the device's visual presence, preventing it from becoming a focal point while enhancing usability.
