The combination of mounting and suspension also considerably reduces manufacturing costs. Current research indicates that numerous flexible spikes exist, and their properties can be further customized. In all applications, the spikes are guided in a reversible direction and held flexibly on this axis by mechanisms. See our European patent application EP23197209.2. A comprehensive prior art search has already been conducted for this application. In this version, the spikes are mounted three-dimensionally (Fig. III flexible working paths, items 10, 11, 12, and 16).
