With Separate Inflatable Inserts TRIZ Cases

A foamed polymer layer between closed tube walls limits puncture damage to one layer while preserving low weight, air retention, and cushioning.

A vulcanized rubber gasket valve lets a hollow tire hold high-pressure air, improving load support, buffering, and tire life.

Independent inner-tube pressure control reshapes the tire contact patch to even ground pressure, reduce wear, and improve vehicle stability.

A nested inner tube with excess circumference forms pressure-driven folds that move around punctures and limit air loss without heavy inserts.

Detachable air blocks between tire spokes preserve cushioning and high-speed stability without air filling, while simplifying replacement after damage.

Overlapped thermoplastic sheets form a reinforced inner tube that avoids size-specific molds while improving strength and puncture resistance.

Linear actuators inside the tire cavity adjust sidewalls to shrink the tread contact patch and cut rolling resistance in city driving.

A reinforced zenith layer in a TPE inner tube improves puncture resistance with low rolling resistance and easier tire-tube recycling.

Pressurized cohesive layers, segmented chambers, and septums help a pneumatic tire self-seal punctures and keep supporting vehicle load.

Internal air pressure locks the sleeve-joined inner tube ends together, preventing detachment, clearance, and bumpy riding during replacement.

A condition-responsive vent links tire air chambers during inflation, then isolates them to simplify filling while limiting leakage after failure.

A tackifier-free cured silicone composition keeps long-term tack and seals tire punctures across extreme temperatures.

A lubricating layer between the inner tube and tire casing cuts low-pressure friction, preventing wear, air leakage, and safety loss.

Partition walls create multiple tire air chambers to preserve run-flat travel distance without the harsh ride, weight, and fuel penalties of reinforced sidewalls.

Inflation-expanded end surfaces lock inside a sleeve to keep a split inner tube secure, gap-free, and easier to replace.

A free-standing membrane and annular hoop hold tire electronics in place without adhesives, simplifying assembly while preserving tire integrity.

A threaded ring-and-plug mount gives inner tubes removable access for accurate pressure and temperature sensing inside the air cavity.

A tire pressure control circuit uses a single air line and spool valve to manage inner tube and outer cavity inflation.

A wheel assembly uses a deformable chamber filled with jamming particles and interstitial gas to conform to terrain.
