Recently many studies have been devoted for understanding the nucleon-nucleon interaction and the atomic nuclei structure starting from quark models. The way for this problem solution selected by us is based on a nontraditional consideration of the confinement of valence quarks in cases when two, three or more nucleons approach each other and the corresponding confinement potentials come into contact and vanish. The overlap of wave-functions of valence quarks, trapped in different nucleons, causes correlations thus giving the possibility to understand the peculiarities of the nucleon-nucleon interaction and corresponding potential modifications in case, when interacting nucleons are present in atomic nucleus. The investigated systems of double-, triple- and larger number of confining harmonic oscillator wells opens new possibilities for recent realistic nucleon-nucleon potentials modifications taking into account the substructure of interacting nucleons. Nucleons entering the interaction area change due to the intrinsic structure modification. These changes are dependent on the presence of "spectator" nucleons in vicinity of interacting ones. This observation can serve as alternative of three nucleon potential necessary for lightest nuclei description.
