Design and exploration of inverted buckle structure

Abstract: In the design of plastic packaging, due to limitations in materials, processes, or requirements in
terms of structure, function, etc., it is usually necessary to split a package into multiple components. In addition
to bonding and welding, one of the common ways to connect components is through a snap fit connection.
The main forms of inverted connections include buckle hole connections and interlocking connections
between buckles. This article will explore in depth the design points and techniques of inverted structures
through a combination of theoretical calculations, empirical design, simulation analysis, and theoretical
verification, in order to improve the efficiency of inverted functional design, and introduce two representative
inverted structures.
Key words: packaging design; packaging structure; structural design; inverted structure; simulation
