Hollow Inflatable Balls TRIZ Cases

Thermal bonding replaces stitching in sport ball casings to eliminate excess seam mass and improve manufacturing efficiency.

A ball integrates a self-adhesive member supported by a reinforcing structure to enhance grip.

A helically twisted tubular retention portion holds a visible center object within a transparent spherical skin to enable radial movement.

A game board features a retractable plank extending from the back panel to create variable target areas for weighted ball projectiles.

Welding thermoplastic polymer panels eliminates stitched seams to reduce sport ball mass and improve aerodynamics.

Adhesive panel bonding and hanging bladder design reduce air leakage and concussion risk.

A sports ball integrates symmetrically disposed light emitting structures within a woven shell and dual-layer housing to produce clear illumination.

A ball featuring a vulcanized foam layer with partition portions having lesser cellular density than the main portion to create a specific surface texture.

Thermal bonding replaces hand stitching on embossed soccer ball panels, reducing manufacturing costs while improving abrasion resistance.

Heat shrinking cross-linked polymer film around the bladder improves tensile strength and rebound while ensuring uniform dimensions.

A dual-lace closure system uses a flexible first lace and inelastic second lace to secure object portions together.

Segmented components and dynamic resistance bands resolve the contradiction between ease of use and multi-functionality in home therapy tools.
