In this paper, we propose the general methods, yielding uninorms on the bounded lattice $(L,\leq ,0,1)$, with some additional constraints on $e\in L\backslash \{0,1\}$ for a fixed neutral element $e\in L\backslash \{0,1\}$ based on underlying an arbitrary triangular norm $T_{e}$ on $[0,e]$ and an arbitrary triangular conorm $S_{e}$ on $[e,1]$. And, some illustrative examples are added for clarity.
