Choosing a basic torso sex doll and saving the budget for the head can invest in upgrading the tactile feedback system - for example, implanting a 16-point touch array in the chest cavity to obtain a richer interactive experience. This resource optimization strategy maximizes sensory returns with a limited budget. The weight of the head changes the mechanical balance. Actual measurements show that a torso sex doll with a standard silicone sex doll head is prone to tipping over in the riding position due to the 1.2kg extra head weight. The engineering solution is to inject weighted lead pellets into the pelvis, but this increases the cost by 15%. The headless version has a naturally stable center of gravity and supports difficult positions such as inverted and hanging. This difference in physical properties directly affects the boundaries of experience diversity. |
