Abstract: With the development and progress of modern manufacturing technology and the continuous improvement of user aesthetic art, the innovative design that only focuses on software and hardware while neglecting structure and appearance in product design can no longer meet the use and aesthetic requirements of current users. Therefore, a design scheme for a portable servo motor measurement and controlling instrument is proposed in this paper. A detailed design explanation is carried out mainly from the structure, appearance, color and other aspects of the measurement and controlling instrument. This design scheme not only meets the basic functions of the measurement and controlling instrument, but also increases its aesthetic appeal and thus greatly improves the market competitiveness of the measurement and controlling instrument.
