Abstract: In the context of “organized research”, this study proposes an intra-laboratory rotation system based on a “one-primary, multiple-supplementary” framework for large research teams. The “primary” component centers on mentor teams responsible for major national engineering projects, while the “supplementary” component involves rotations across different research directions within the team. Under the premise of clearly defining students’ primary laboratory affiliation, this system facilitates rotation among various research subfields. The intra-laboratory rotation mechanism offers constructive guidance for fostering students’ personal development, supporting multidisciplinary innovative research by faculty, and enhancing the capacity of engineering institutions to undertake major national engineering projects.
