In many cases in hydraulic transmission systems, cylinders with locking functional units are often necessary. As for the optional position locking technology, the interference fit connection integrated with locking and assembly methods which are mainly adopted in modern engineering are addressed. Under the background of this, status quo of this technology’s application is summarized. On this base, the ideas and optimal design methods for engineering tailored development, which is used for cylinders’ locking units, are introduced and proposed via analyzing the force, form and structure of loading. Then, the modular-based and systematic development and application architecture that meets the engineering requirements well is established according to a summary of characteristic indices and device performance, and this, in turn, will support the extension and application of this technology and help to find innovative solutions for corresponding product manufacturing and services offering.
