The promotion of the
fat sex doll is driving technological innovation in the sex toy industry. To accurately reproduce the anatomical features of full-figured bodies, manufacturers have developed new material formulations and structural designs, advancements that are often subsequently applied to standard full-body sex dolls. The design challenges of fat sex dolls have forced engineers to rethink issues such as weight distribution, joint load-bearing, and durability, driving technological upgrades across the industry. Compared to relatively simple
full body sex doll designs, fat sex dolls require more complex technical solutions. This pressure for innovation ultimately benefits all product types, demonstrating how a diverse product line can drive overall industry progress.
