The 2023 Research Report on Aging of Silica gel and TPE Materials indicates that rpsexdoll should store at ambient temperature of 20°C±2°C and relative humidity of 30%-50% for a long period of time, over which the rising oxidation rate of silica gel increases from 0.8%/year to 1.5%/year (detection using FTIR spectroscopy). The rate of decrease in TPE material tensile strength varies from 3%/year to 7%/year. Experimental results show using constant temperature and humidity cabinet (power ≤60W, ±0.5°C accuracy temperature) will be capable of increasing material lifespan by up to 118% nominal value (such as RealDoll official testing: 10 years stored in storage space, joint tensile strength remaining still 98MPa, a mere 2% reduction). For example, in 2022, A user stored the rpsexdoll in the attic (-5°C to 40°C annual temperature fluctuation), causing the hip silicone to harden to Shore Type A hardness of 35 (initial value of 15), and the cost of repair was 27% of the initial cost.
Storage posture has tremendous impact on structural stability. When false, rpsexdoll’s spine supporting is always subjected to ≥15kg/m² pressure. With no multi-point supporting (recommended distance ≤30cm, effectiveness of load transmission 85%), 0.8-1.2mm plastic deformation After 6 months can be anticipated. EXDOLL laboratory data from Japanese maker prove vertical suspension storage (special hanger bearing ≤50kg, contact surface pressure < 5kPa) can reduce the rate of joint wear to 0.03%/year, whereas flat storage wear rate is 0.12%/year. In 2023, a Shenzhen warehouse company stacked up 300 rpsexdoll (3 layers, bottom pressure 22kPa), resulting in 63% of the products being irreversibly deformed and direct losses of over 2 million yuan.
The cleaning and maintenance cycle must strictly conform to the properties of the material. Special detergent with pH value between 6.5-7.5 must be utilized before storage (dosage ≤20ml/m²) and the < 0.01g/m² residue rate can inhibit breeding of microbes along the surface of the silica gel (the total number of microbial colonies CFU/cm² decreases from 10⁶ to 10²). The German TUV certification indicates that the intelligent parts of the rpsexdoll driven by monthly power (for example, heating device running for 10 minutes with an A power of 30W) can extend the capacitor lifetime of the circuit to 8 years from 5 years, and leakage current is controlled at < 5μA. One of the user cases illustrated that due to 18 months of continuous maintenance in the absence of electricity, rpsexdoll’s AI chip was destroyed due to moisture and the repair cost was 15% of the entire value (around $1,200).
The packaging material selection is directly related to storage security. The use of 0.08mm thick anti-static aluminum foil vacuum bag (oxygen permeability ≤0.5cm³/m²/day) in combination with silica gel desiccant (dosage ≥20g/kg) can narrow down the range of internal humidity change from ±15% to ±3%. ASTM D4169 standard test points out that compressive strength of this package can be up to 80kPa (6 times than normal PE film) and transportation vibration transmission can be reduced to 12%. The technology-intensive storage box that Dutch firm DollShell introduced in 2024 (intrinsic buffer layer density 45kg/m³, seismic frequency 5-100Hz attenuation rate ≥90%) has reduced the level of transportation damage from the benchmark 7.3% to 0.9%, but at a price of one box for as much as $380.
Technological innovations are revolutionizing storage solutions. The smart storage pod launched by RealDoll in 2024 (integrated UV-C sterilization module, wavelength 275nm, 8W) has the capability to kill 99.9% pathogens within 30 minutes, and dynamically adjust the rpsexdoll pose by a pneumatic support system (pressure 0.05MPa) in order to avoid local pressure > 2kPa. Tests showed that the solution reduced the average annual increase in the silicone yellow index (YI) from 4.2 to 0.7, even though equipment cost was $2,500 and the payback was 7.3 years (based on savings of $340 / year in maintenance). In the future, by applying phase change material (PCM) temperature control technology (heat storage density ≥200kJ/kg), this issue of extreme environmental storage will be perfectly resolved and place rpsexdoll’s entire life cycle management into a new phase.
