Hollow Ball For Egg's Protection · 模型 258014
My entry for the challenge, based on the idea, using a hollow ball, together with a threaded cover for adjusting the egg in axial direction and closing the hollow ball. The principle of a trampoline helped me, to make a design with spring elements like cup springs, which hold the egg in axial direction in the center of the hollow ball. For elastic fixation in radial direction I used two separate spring element rings, which are able to hold the egg, similar in a cage. The outer ball housing diameter is 100 mm and the general wall thickness is 3 mm. The thickness of the spring elements is 1 mm. The model of the egg I've carried over by "Seishiro Okazaki". The egg has to be inserted in a pre defined position, before closing the hollow ball with the threaded cover, to get no axial clearance of the egg. The preferred material for 3D-printing is »ABS«, but unfortunately I can't call a 3D-Printer my own, so that I could not test my proposal. An additional small hint: My proposal also could easily tested on a bowling alley ;-) or you could throw the assembly against a wall, from a specified distance and with an inital velocity. Further technical notes: Impact velocity after a fall of 4,572 m : 9,471 m/s Density of »ABS« for calculation of the mass : 1,04 g/cm^3 Volume of the complete assembly (without egg) : 106,86 cm^3 Mass of the complete assembly (without egg) : 0,111 kg Potential Energy (without egg) : 4,9 J = (Nm) = (Ws) Spring are elements not calculated resp. no FEM-analysis done. The result of my design - may be, because not yet tested - is a concept only! Model available in the following data formats: STEP-file (.stp) of the complete assembly (2 components and egg included) STL-files of the 2 components for 3D-printing Native data (.prt) and (.asm) in a "zipped" folder for users of »PTC Creo Parametric 2.0« Thank you for your attention!
