The introduction period of the bladeless fan refers to the stage where bladeless fans are successfully developed, begin entering the market, and undergo trial sales while gradually achieving product commercialization. During this phase, due to the lack of consumer understanding about the bladeless fan, the growth in sales volume is slow and unstable, presenting significant market resistance. Additionally, as the bladeless fan is a new product, it comes with a higher price point, and requires financial investment for promotional activities in order to penetrate the market.
