Developmental Design: Applying mature design experience or feasible new technologies to design new mini excavators, mainly including functional and mechanical design.
Upgradeable Design: Updating and updating existing mini excavator designs based on usage experience and technological developments to improve performance, reduce manufacturing costs, or decrease operating expenses.
Derivative Design: Modifying or adding to existing mini excavators to meet new needs, thus developing derivative products different from the standard model.
Serial Design:Using a single mini excavator as a base, designing a series of products with the same function and similar appearance, but differing in power, tonnage, and size.
