Through this design, the designer expressed the rigorous, precise and stable temperament of this product. At the same time, in terms of details, designers also use simple design elements to set off the quality of the product. The symmetrical decorative stripes up and down, the horizontal division of left and right echoes, the distinctive symbol slope of the connection port, and the characters of the side product model all reflect the delicacy of the design. The design of these details fully improves the quality and beauty of the product. In terms of processing technology, the designer has carried out a reasonable design in full combination with the actual needs of users. The whole product is divided into front shell and rear shell, and the appropriate design is carried out on the premise of ensuring the stability of product installation. After discussion between the designer and the mold engineer, a brand-new improvement has been made to the original wiring port. After mass production, the product has risen to a new level in terms of assembly maintenance and color value.
