The Advancement of Realistic Sex Dolls

One area where manufacturers have focused their efforts on significant enhancements is the skeleton. Traditionally, sex dolls of various sizes utilized a classic steel skeleton due to its simplicity and cost-effectiveness. While this skeleton design has proven reliable, it does have its limitations. For instance, the head is connected to the skeleton through a flexible pipe, resulting in a neck, also known as the "gooseneck," that may lose some of its posing ability over time and produce slight noise when bent. Moreover, the range of movements is limited, and the lack of hinged joints in the wrists and ankles leads to similar issues as the "gooseneck."

In recent years, manufacturers such as Doll Forever have begun gradually upgrading the classic skeleton. Notable improvements include the introduction of fully hinged neck joints, and replacing the neck pipe joint. This new joint eliminates creaking noises and enables their sex dolls to maintain poses consistently. The increased solidity of the hinged neck joint also allows for a safe suspension of these brands' sex dolls for a limited time, utilizing a special suspension kit. Similarly, these manufacturers have incorporated fully hinged wrists into their sex dolls, enhancing their range of movements.

Another significant enhancement is the pelvis torsion feature, pioneered by YL Doll in 2016 with the release of their 155cm small-breasted sex doll. This innovative addition enables more realistic poses, making the sex dolls ideal for photography and various other purposes. Since then, the majority of manufacturers in the catalog have adopted the pelvis torsion feature. Dollhouse168 and Doll Forever have gone a step further by allowing lateral bending of the sex dolls' bodies from right to left.

Furthermore, Dollhouse168 introduced shoulders that can shrug, featured in their EVO sub-brand, implementing this advancement in all their sex dolls. These shrugging shoulders greatly expand the range of motion and add to your sex dolls' overall realism.

The range of movements for TPE/silicone sex dolls has been dramatically increased through these skeleton upgrades. A notable breakthrough comes from Dollhouse168 EVO, whose sex dolls can safely sit on their legs in the "seiza" and "W" positions, further enhancing the authenticity and posing possibilities.

Head connection mechanisms have also undergone improvements. Most brands in the catalog now feature the M16 head connection bolt, allowing inter-compatibility among them. Brands such as WM Dolls, YL Doll, OR Doll, Dollhouse168, Doll Forever, JY Doll, Climax Doll, 6YEDoll, and IL Doll utilize the M16 head connection system, which involves screwing the head onto the body to secure it. However, brands with different attachment systems have their own mechanisms, rendering their heads incompatible with those from other brands. For example, EXDOLL developed a lock-up head attachment system that eliminates the need for head rotation. This system has gained popularity among sex doll users, leading other brands to adopt the same approach. Dollhouse168's EVO sub-brand, for instance, has chosen the lock-up bolt system. Additionally, a hanging kit for easy storage is provided as a free add-on.
