Abstract: For the purpose of solving the "bottleneck" problems of production, we helped a factory in organizing a shop nuclear sub-group. This sub-group provided the workers with some provocative materials, mainly in the oral and written form of provocativeness, as well as thru the use of prototypes such as diagrams and photographs, etc. These workers with the help of these materials, have invented ten sets of automatic and semi-automatic punching and die, thus laying down the foundation for the solution of the "bottleneck" problems.During the working processes, we joined the workers in discussing and in laboring, and observed and recorded the actual processes of the creative thinking activities of the workers. From these resuks we may single out these following points;1. Creation of new, machines-like automatic punching and die may be accomplished through a mass movement, a well-planned and'concentrated efforts of attack.2. Verbal presentation of problems and prototypes such as diagrams and photographs relative to the machinery can powerfully provoke and prorriote creative thinking of the workers.3. Creative thinking finds its origin in the necessity of social production. It is produced and developed in the course of practical activities and is the reflective process of objective laws.
