Fit Sex Doll not only pursues realism in appearance and touch but also meticulously designs its internal structure to simulate the natural postures and movements of the human body.

Understanding the internal skeleton structure of these dolls can help users use and maintain them better, enhancing the overall experience and satisfaction.

Below, we delve into the internal skeleton structure of Fit Sex Doll, revealing its professional and realistic design philosophy. 

1. Internal Skeleton Materials

The skeleton of Fit Sex Doll is usually made of metal materials, mainly steel or aluminum alloy.

These materials provide sufficient strength and durability, ensuring the stability and reliability of the skeleton during use.

Steel skeletons typically have higher strength, suitable for parts that need more support, while aluminum alloy is widely used in parts that require flexibility and maneuverability due to its lightweight characteristics.

2. Joint Design and Flexibility

To simulate the natural movements of the human body, the skeleton of Fit Sex Doll is designed with multiple joints.

These joints usually include the shoulders, elbows, wrists, hips, knees, and ankles. Each joint is precisely designed to achieve a certain range of bending and rotation, allowing the doll to pose in various positions.

• Shoulder Joints: Can move forward, backward, and up and down, simulating human shoulder movements.
• Elbow Joints: Allow the forearm to bend and rotate, enhancing arm flexibility.
• Hip Joints: Allow leg movement forward, backward, and sideways, adapting to different posture requirements.
• Knee Joints: Enable knee bending, allowing the doll to sit or kneel naturally.
• Ankle Joints: Provide a certain degree of rotation and bending, making foot movements more natural.

3. Details of Fingers and Toes

Finger Joints

The finger joints of Fit Sex Doll generally come in two designs: articulated joints and wire.

• Articulated Joints: This design uses multiple micro-hinges, allowing the fingers to bend and rotate independently, simulating the flexibility of human fingers. Articulated joint fingers are more durable but have a more complex structure.
• Wire: This design uses wires as the support for the fingers, enabling basic bending movements. Wire-designed fingers are lighter but relatively less flexible than articulated joints.

Toe Joints

Currently, most Fit Sex Dolls have functional joints only in the big toes, while the other toes are soft structures. However, with continuous technological upgrades, some advanced models have started to feature articulated joints in all toes, enhancing realism and flexibility further.

4. Connection of Skin and Skeleton

The skin of Fit Sex Doll is usually made of high-quality TPE (thermoplastic elastomer) or silicone materials, which have high softness and realism. The connection between the skin and skeleton is achieved through internal filling materials.

These filling materials not only maintain the skin's firmness and elasticity but also provide cushioning between the skeleton and skin, preventing excessive friction and wear.

5. Adjustment and Maintenance of the Skeleton

Users can adjust the posture of the Fit Sex Doll's skeleton as needed. When adjusting, care should be taken to handle gently to avoid applying excessive pressure on the joints.

Regularly checking the tightness of the joints and the overall condition of the skeleton helps extend the doll's lifespan.

Some high-end Fit Sex Doll models are equipped with anti-rust treatment on the skeleton, further enhancing durability and ease of maintenance.

6. Usage Precautions

With the evolution of skeleton technology, more brands are upgrading to EVO materials. This material enhances the durability and flexibility of the skeleton and improves the overall user experience.

However, users should consider upgrading the heating system when choosing to upgrade to an EVO skeleton.

Typically, the heating system might cause some damage to the internal skeleton, so special attention to temperature control and system maintenance is needed during use to ensure compatibility between the heating system and the EVO skeleton.

Conclusion

The internal skeleton structure of Fit Sex Doll, through the use of high-strength materials, multiple flexible joint designs, and detailed skin connections, achieves a high degree of realism and stability.

Understanding these internal structures not only helps users better use and maintain the dolls but also allows a deeper appreciation of the professionalism and care behind the design.

Whether in terms of touch, posture, or overall experience, Linkdolls continually strives for excellence to provide users with the most realistic and satisfying experience.
