  Using purely geometrical methods we present a mechanism to solve the scalar
field equations of motion (non-minimally coupled with gravity) in a spherically
symmetric background. We found that the \emph{full }set of spacetimes, which
are of Petrov type O (conformally flat) and admit a \emph{gradient} Conformal
Vector Field, can be determined completely. It is shown that the full group of
scalar field equations reduced to a \emph{single} equation that depends only on
the distance $w=r^{2}-t^{2}$ leaving the metric function (equivalently the
functional form of the scalar field or the potential) freely chosen. Depending
on the structure of the metric or the potential $V$ (as a function of $\phi $)
a solution can be found either analytically or via numerical integration. We
provide physically sound examples and prove that (Anti)-de Sitter fits this
scheme. We also reconstruct a recently found solution \cite{Strumia:2022kez}
representing an expanding scalar bubble with metric that has a singularity and
corresponds to what is termed as Anti-de Sitter crunch.
