Yes, the examination of the novelty and inventiveness of a patent is based on the filing date (if there is priority, the priority date). Your disclosure of the technical solution after the filing date will not destroy the novelty and creativity of the patent application.
It should be noted that the patent office will only disclose utility model and design patent application documents after they are authorized. If you disclose a technical solution yourself and the utility model or design patent is not authorized in the future, the technical solution will be published in vain.
