Waterbomb base: a symmetric single-vertex bistable origami mechanism

Abstract

The origami waterbomb base is a single-vertex bistable origami mechanism that has unique properties which may prove useful in a variety of applications. It also shows promise as a test bed for smart materials and actuation because of its straightforward geometry and multiple phases of motion, ranging from simple to more complex. This study develops a quantitative understanding of the symmetric waterbomb baseʼs kinetic behavior. This is done by completing kinematic and potential energy analyses to understand and predict bistable behavior. A physical prototype is constructed and tested to validate the results of the analyses. Finite element and virtual work analyses based on the prototype are used to explore the locations of the stable equilibrium positions and the force–deflection response. The model results are verified through comparisons to measurements on a physical prototype. The resulting models describe waterbomb base behavior and provide an engineering tool for application development.

Reentrant Origami-Based Metamaterials with Negative Poisson’s Ratio and Bistability

“…However, there have been limited efforts to study the cylindrical derivative of Miura-ori in the form of TMP [14]. In contrast to 2D origami structures such as Miura-ori sheets and waterbomb [15], the TMP holds a volume that changes continuously from zero to a certain value, and then it returns to zero again at the ends of the folding motion (see Fig. 1(a)).…”

Origami tubes with reconfigurable polygonal cross-sections

“…This phenomenon is similar to conventional bending drinking straws ( figure 19c). The physical models of the polygonal tubes also showed some bistable and multi-stable effects, similar to other origami structures [46][47][48]. Multi-stability with the reconfigurable tubes could provide new ideas and applications.…”

“…Ako argumentuje Brandon Hanna a kolektív (Hanna et al 2014), na poli aplikovaných prác inšpirovaných skladaním v rôznych odboroch vedy a techniky (tzv. Origamics) je waterbomb najčastejšie sa objavujúcim kinetickým mechanizmom.…”
