Through the innovation of "elastic cushion layer" combined with ergonomic design, the schoolbag pressure is transformed into dynamic buffer and uniform support, which significantly reduces the burden on shoulders and backs and provides active protection for the healthy development of school children's spine. Reconstructing the sneaker midsole cushioning principle into a back ridge protection system, 12000 + TPE ultralight microspheres flow freely in the air compartment to achieve:

1. Pressure self-adaptation: microspheres are recombined in real time to form a fluid support layer, with a shoulder load of ↓ 30%.
2. Accurate curvature matching: automatic filling of lumbar 5-7cm physiological curvature gap (fitting error ≤ 1.5mm).
3. Impact particle decomposition: 65% of the vertical kinetic energy is dissipated by microsphere collision.

By innovating the "elastic air cushion layer" combined with ergonomic design, the pressure of the backpack is transformed into dynamic buffering and uniform support, significantly reducing the burden on the shoulders and back, and providing active protection for the healthy development of the spine of students.
Refactoring the midsole cushioning principle of sports shoes into a back protection system, with over 12000 TPE ultra light microspheres flowing freely in the air chamber, achieving:

1. Pressure adaptive: Microspheres recombine in real-time to form a fluid support layer, with a shoulder load of ↓ 30%.
2. Precise curvature matching: Automatically fill the physiological curvature gap of 5-7cm in the lumbar spine (fitting error ≤ 1.5mm).
3. Impact particle decomposition: 65% of vertical kinetic energy is dissipated through microsphere collision.
