Guarding Every Step of Childhood: The Philosophy of Careful Design Behind Children's Backpack 19

When the first ray of sunshine in the morning shines into the window, the picture of the child carrying a schoolbag on the road to knowledge is gratifying but full of worry. In response to this general concern, the designers of "Children's Backpack 19" went deep into the school classroom and family visits, and after understanding the learning pressure and physical development characteristics faced by modern primary school students, they formulated an exclusive solution-the overall frame structure composed of lightweight skeleton support and flexible buffer filling, which reduces the weight-bearing perception to the greatest extent on the basis of ensuring firmness and durability.

Farewell to Heavy Burden: Revealing the Innovative Structure of Scientific Burden Reduction System

Different from the traditional practice of widening shoulder straps to ease weight distribution, "Children's Backpack 19" has created an original pressure equalization system composed of X-shaped cross fixing straps and bottom lifting plate. This kind of technology similar to mountaineering professional equipment has been miniaturized and transplanted to the field of student supplies, and has been highly recognized by pediatric orthopedists: "The correct force distribution helps prevent the occurrence of juvenile hunchback." A hospital rehabilitation center professor said.

Rain is not afraid of soaking: analysis of the all-round protection capability of high-density waterproof fabrics

Horizontal evaluation of three mainstream fabric performance parameters (unit/mm²)
Material type	Tear strength	Water pressure resistance value
Polyester regular Polyester Cloth	≈35N	≤100mmH₂O
TPE composite film laminated cloth	≈48N	>500mmH₂O
XFP nano water-repellent fiber (this product)	≈60N	>1000mmH₂O

In order to cope with the sudden challenge of harsh weather, we have made great efforts in the selection of outer fabrics. The microfiber microporous membrane is combined with a tightly woven base tissue to form a double barrier effect that prevents the penetration of important documents inside even in a downpour. Continuous spray tests in a laboratory environment have shown that it can withstand rainstorms for at least two hours without leaking a drop of rain into the main silo area.

don't want to change your back: breathable back pad technology creates all-weather dry experience

• "I used to sweat and feel sticky behind my clothes when I came back from school. now there is basically no problem ~"
• "No matter how hot it is in summer, you don't have to worry about sweating too much and soiling your clothes. It's also easy to clean."

Taking into account the active and metabolic physical characteristics of school-age children, a set of honeycomb-shaped three-dimensional ventilation groove network was specially developed to be embedded in the back liner. The device can automatically adjust the change of temperature difference between inside and outside to promote the smooth circulation and exchange of air flow, which greatly reduces the probability of skin allergy caused by hot and humid.

Orderly Growth Assistant: Extension of Teaching Value of Multi-zone Storage System

Good habit formation often begins with seemingly simple repetitive exercises. The White Paper on Quality Education in Primary Schools points out that students with well-organized personal space have an average concentration of nearly 1/3 higher than their peers...

Based on the guidelines of the above research results, a variety of storage unit configuration options including the front bag emergency supply grid, the side sports kettle clamp, and the top quick-take identification card are constructed. Encourage children to independently arrange the number of types of objects they need to carry every day, so as to establish a good sense of order and sense of responsibility.
