This paper introduced the finite element analyses to evaluate numerically and objectively the feelings in the fingertip when opening aluminum beverage cans in order to design the shape of the tab. At first, experiments of indenting vertically the fingertip pulp by a probe and tabs of the aluminum beverage can ends have been done to observe force responses and feelings in the fingertip. It is found that a typical force-displacement curve may be simplified as a combination of three curves with different gradients. We feel a touch at Curve 1 of the force-displacement curve, then feel a pressure and our pulse at Curve 2, finally feel discomfort followed by a pain in the fingertip at Curve 3. Moreover, the finite element analyses have been performed to simulate the tab indenting the fingertip vertically to confirm that the simulation results agree well with the experimental observations. Finally, numerical simulations of finger pulling up the tab of the can end has also been performed and discomfort in the fingertip has been presented by the maximum value of the A paper submitted to Applied Ergonomics 2 contact stress of the finger model. Comparisons of three kinds of tab ring shape designs showed that the tab that may have a larger contact area with finger is better.

“…As the absorber component of cars, cylindrical shells have been optimized to absorb more crushing energy during car crashing (Yamazaki and Han 1998). As crushable beverage cans, cylindrical shells have also been triangulated and optimized for recycling after drinking (Han et al 2004). In order to optimize effectively a design problem with many design variables in complex geometrical relations, the Design Variable Progressive Optimization method based on RSA is proposed and applied to optimize the bottom of 2-Pc aluminum beverage bottles (Han et al 2005).…”

This paper deals with a multi-objective optimization of a screw-top beverage bottle for hot vending. The bottle body has temperate touch feeling, and can be embossed easily by axially imposing a cylindrical tube die with rib-shaped inner surface on the outer surface of the bottle body. Initially a contact nonlinear analysis of fingers grasping the bottle is carried out, and the amount of heat transmitted from the hot bottle to the flesh of the finger is then calculated to evaluate the hot touch feeling.Meanwhile, the simulation of the rib-shape embossing process of the bottle body is performed to evaluate the embossing formability of different rib shape designs. Finally, 3 using Response Surface Approximation method and Weighted Sum Approach, a multi-objective optimization on the shape of the rib is performed to obtain temperate touch feeling as well as better embossing formability. The amount of heat transmitted from the optimized rib-shape embossed bottle decreased at least 30% as compared with that of the regular bottle.

Abstract. This paper introduced the finite element analyses into the ergonomics designs to evaluate the human feelings numerically and objectively. Two design examples in developing aluminum beverage cans & bottles are presented. The first example describes a design of the tab of the can with better finger access. A simulation of finger pulling up the tab of the can has been performed and a pain in the finger has been evaluated by using the maximum value of the contact stress of a finger model. The finger access comparison of three kinds of tab ring shape designs showed that the finger access of the tab that may have a larger contact area with finger is better. The second example describes a design of ribshape embossed bottles for hot vending. Analyses of tactile sensation of heat have been performed and the amount of heat transmitted from hot bottles to finger was used to present the hot touch feeling. Comparison results showed that the hot touch feeling of rib-shape embossed bottles is better than that of cylindrical bottles, and that the shape of the rib also influenced the hot touch feeling.
