其他摘要：The structure of the second-generation hanging components in fire helmet is improved greatly based on the first-generation fire helmet. Thus, the performance can be improved, since the actions are reduced in order to free up a hand for other things. It also operates conveniently with the structure simplified and no longer folds face. It can be said that the hanging component of the fire helmet becomes a completely new product. This is the example of case intro- duction, assimilation, absorption and transformation. The so-called improvements and innovations are technological innovations and technological improvements, which mainly mean to search for the defects and inconveniences in the products, and then to find the solution to solve the problem. The specific method is to identify the problems in practice.
