In order to have market competitiveness in the area of massage chair in domestic, it is necessary to establish a tactical promotion plan in terms of developing new technology and rethinking competitiveness. So, this research addresses four things, The first is to report an analysis that is for external environment changes and competitors the current situation through surveying the market trends of massage chair. The second is current technology of massage chair through surveying current technical trends of massage chair. In the basis of the surveying, the third is to establish alternative future technology for the chair. Finally, the last is to establish a counter-plan by analysing internal status and competitive power of each enterprise. On the basis of four things above, the future promote strategy and subject are proposed in this paper by producing the four strategic subjects.

The customer of massage chair is expanding day by day from middle age to all ages. In 2018, the market size was 700 billion KRW, an increase of 30 times over 10 years. However, most related SMEs suffer from excessive competition by the market monopoly of some major companies. In this situation, in order for a related company to survive, it is necessary to steadily research and develop new products. Founded in 2009, company L produces massage chairs for health and relaxation of customers. L's products use a sound wave vibration module that is favorable for human body, unlike other products that use vibration motor type. However, frequent breakdowns of massage chair due to the vulnerability of plate (leaf) springs, which play an important role in sound wave vibration modules, made sap its competitiveness. In this paper, we propose a method to design desirable plate spring structure by sequentially experimenting with five different plate springs. The results of this study are expected to contribute to improve the quality of plate spring and the reliability of sound wave vibration module. In the future, it is necessary to find a way to use it in the development of foot massage or scalp management device as well as continuous research to find optimal plate spring structure through various analysis.
