AI Technical Summary

Technical Problem

Existing dumbbell plates are too wide after inflation, making it impossible to maintain their thin shape. This results in poor stability when mounted on the handle, and the flexible body is prone to wear and tear, lacking cushioning protection in case of accidental drops.

Method used

The design incorporates a two-sided clamping structure. The clamps compress the flexible body to maintain its sheet-like shape, and a cylindrical support is provided in the middle. The clamps do not completely cover the sides of the flexible body. After the flexible body is inflated, it expands outward to provide cushioning. A flexible traction section is set between the clamps and the flexible body to limit lateral expansion.

Benefits of technology

This design allows for stable mounting of dumbbell plates on the handlebars, preventing wear and tear, increasing stability and cushioning, and preventing damage in case of accidental drops.
