Origami fold states: concept and design tool

Abstract

Abstract. The ability of origami to alter its properties and behaviors with its shape makes it an elegant source of inspiration for many engineering designs challenges. Fold states specify the shape of the origami – its facets, creases, and fold angles. Origami research recognizes several acknowledged fold states: the unfolded, fully folded, and flat-folded states. However, these fold states are not comprehensive, excluding some of the most predominant fold states in origami-based devices. In this paper we propose a comprehensive list of fold states based on fold angles. We support the method of categorizing fold states by evaluating the functions and fold states of a large sample of origami-based devices. These correlations provide insight for selecting fold states for origami-based design. We discuss properties and behaviors of the fold states individually and provide a process for fold-state selection.

Incorporating Shape-Changing Food Materials Into Everyday Culinary Practices

“…Origami originates as a Japanese art form, which is now widely implemented as a form-giving tool, appropriate for ideation techniques. It is applied in product design [10], architecture [12], fashion [9] and given its complex mechanical qualities [6], origami and its variation kirigami (which also involves cutting the paper) have inspired various researchers in HCI to use it in the context of shape-changing interfaces [e.g., 13,35]. However, the use of origami in food projects is scarce, although it can be compared to traditional cooking techniques involving ravioli, dumplings, sushi, or marzipan pie decorations.…”

Kegiatan Melipat Kertas Lipat Bermotif untuk Meningkatkan Kemampuan Motorik Halus Anak

“…Selain itu guru kurang mempertimbangkan kemampuan dan karakteristik anak, guru perlu meningkatkan keprofesional dalam mengajar demi mencapai tujuan pembelajaran dan perkembangan anak dapat berkembang dengan baik, salahsatunya yaitu perkembangan motorik halus.

Revisão de pesquisas em design de origami na área médica

“…Os vincos são juntas de dobradiças rotativas formadas a partir da deformação do material, sendo um recurso linear onde ocorrem as dobras (AVILA et al, 2019). Os planos do papel giram para cima para formar uma dobra vale e giram para baixo para formar uma dobra montanha (DUREISSEIX, 2012), como esquematizado na figura 3.…”
