Tyre Measurements TRIZ Cases

A timed alert delay filters short tire pressure fluctuations, sending warnings only when low pressure persists and reducing nuisance notifications.

Pressure-threshold flagging helps a tire pressure monitoring unit invalidate outdated tire data after tire changes so vehicle safety systems use current data.

An LF trigger coil activates inner-wheel sensors through double rims, enabling accurate Bluetooth tire pressure checks without removing outer tires.

Wheel pulse counters and rotational acceleration help identify inner and outer TPMS sensors on double wheels, so low-pressure tires can be pinpointed.

A valve stem core secures a replaceable TPMS battery and uses a spring-loaded terminal so users can swap power without deflating the tire.

A timer delays TPMS mode changes after acceleration-based stop detection, cutting unnecessary transmissions and extending battery life.

A two-layer tread and outward-shifting lateral grooves help preserve wet grip and water drainage as tire wear reduces groove volume.

An embedded LC resonator tracks tread wear wirelessly while avoiding leakage paths and reducing metal interference in tire sensing.

A widened fine-groove bottom and higher inner land area help suppress mid-wear uneven tread wear while preserving wet drainage and grip.

Multiplexed quasi-static data lets a TPMS wheel module send mileage, target pressure, and tread depth without extra energy use.

By raising signal frequency only when tire rotation changes, this case speeds tire position detection without increasing wheel unit power use.

A stator-rotor annulus assembly transfers air into a rotating tyre for ad hoc pressure adjustment, improving traction and fuel efficiency.

Direct wireless tire fill guidance raises TPM sampling only during inflation to improve pressure accuracy and avoid overfilling.

Bidirectional TPMS communication uses vehicle-state trigger data to speed sensor auto-location while reducing energy use and improving accuracy.

An RFID tag built into the tire sensor mount transfers tire ID data on attachment, avoiding manual programming errors and integrity risks.

Embedded conductive filaments break at a set tread depth to detect uneven tire wear and wirelessly alert vehicle systems.

Positive and negative waveform peaks let one strain sensor separate mixed tire signals and estimate load and wear more accurately.

An elastomer ring seals and holds snap-fit TPMS housing half-shells, cutting sealing cost while improving repair and recycling.

Voltage peaks from an in-tire triboelectric generator enable more accurate wear and ground-contact estimation when low-speed signals are noisy.

Filtering footprint-area motion from a rotating tyre signal isolates vibration modes for more accurate wear and structural integrity monitoring.

Directional antennas map tire sensor positions by axle side and signal strength, improving wear prediction and maintenance alerts for fleets.

Pre-trip maneuvers and real-time dynamics or image monitoring detect trailer faults, then adjust control or stop the vehicle.
