  The physical pictures of the electron pairing structure and pairing
mechanisms in superconductors are reviewed. An initial idea for a new physical
picture of the origin and nature of the pairing is proposed. The idea is based
on the assumption that the electron is no longer a single fundamental but a
composite particle. This property is hidden in the normal state. How a natural
pairing could occur in the superconducting state and the processes closely
related to this change inside the atom are developed in a new physical picture
with new insight(although it needs verification and real evidence for now). An
attempt, to show that a zero resistance to a direct current and Josephson
effects could be used as example evidences for this assumption, is presented by
means of this new insight in general schematical analogy. A possible new
research direction, hopefully to achieve room temperature superconductors, is
suggested as a consequence. Nowadays, with the great advancements of facilities
used for particle physics, quantum mechanics and applied superconductivity,
there is a great opportunity to observe, fabricate and test and possibly
prove/disprove this new insight
