<p>To realize the deployable parabolic cylinder mechanism with large foldability and modular design, this paper proposes a novel origami-lattice pattern based on the point/line/face symmetry method. And the single degree-of-freedom (DOF) kinematic of the origami-lattice pattern was established based on the spherical four-bar mechanism theory. On this basis, a cylindrical origami-lattice deployable mechanism with multiple origami-lattice patterns was designed and its single-DOF motion was verified by the DOF calculation and mechanism prototype with the origami-lattice modular in serials and parallel. In addition, the different-directions deployable ratio of the cylindrical origami-lattice mechanism with a larger folding ratio and modular design were calculated. The folding ratio in the axis direction could reach up to 250 % when the geometric parameters are determined, which verified the feasibility of applying it to deployable construction engineering.</p>
