AI Technical Summary

⚠Technical Problem

Conventional backpacks require excessive physical strength and strain the user's body due to the generation of torque and additional forces needed to counteract the weight and movement of the backpack, limiting mobility and health impact.

⚗Method used

A labor-saving backpack structure featuring an inverted U-shaped support rod above the backpack body, connected by elastic straps to the shoulder straps, aligning the force and gravity on the same vertical line and providing cushioning through elastic connections to cancel out relative movements.

🎯Benefits of technology

Reduces the need for extra physical strength and minimizes health strain by aligning forces vertically, while the elastic connections provide cushioning, enhancing user comfort and reducing fatigue.
