A portable massage table is constructed from the aluminium foot. The foot is a design of standard extruded profiles that are mutually welded. The aim is to prepare new construction, where aluminium profiles are joined with the polymeric corner joints. Additionally, the production costs are lower, and the weight of food is lighter.
In the beginning, we present the current situation, existing patents, and competitive products. We research construction solutions that prove useful when planning the connecting element following the methodology of fabrication. We prepare cost analysis and the comparison of the selected constructed piece with the existing model. In the analysis, we check mechanical condition in the corner joint under load stress while using the finite element method. We presume that material in the corner joint has isotropic properties. Further, the injection moulding analysis presents the location of the weld line and the orientation of the reinforced fibres in the polymer. The results are implemented when optimising construction and in additional mechanical simulation, where we consider the orientation of fibres. We present fibre mapping from injection moulding simulation to mechanical simulation. In the discussion, we evaluate differences in the results between the simpler homogeneous model and a more advanced model of polymeric materials.
