Tactile Signalling Systems TRIZ Cases

A projection-and-buffer support structure suppresses sub-resonance rocking, keeping vibration feedback in the intended forward-backward direction.

Opposing fluid flow in the actuator gap creates pipe resistance, helping a compact vibration actuator keep output across a wide frequency band.

A pressure sensor and shared vibrator replace snap domes and multiple motors to save space, simplify circuits, and improve tactile feedback life.

A movable-part and driving-assembly layout improves vibration transfer to buttons while keeping circuit connections compact and functional.

Fluid flow in the actuator gap creates pipe resistance, widening haptic frequency response while protecting the coil in a compact structure.

Elastic support keeps the movable body clear of the shaft, improving shock resistance while preserving strong, noise-free vibration.

Inflatable material over discrete apertures creates precise localized force feedback while staying durable enough for clothing integration.

Ambient sound detection and user-location tracking help a mobile electronic unit relay emergency context to unaware or immobile users.

Adds binary wavelet carriage to haptics interchange format, clarifying track timing while enabling efficient decoding and synchronized rendering.

A spring-mounted control adds a second resonant frequency to a single actuator, broadening haptic feedback from sharp ticks to longer vibrations.

A time-threshold control suppresses repeated sound, vibration, or display alerts when notifications arrive too close together.

Linear and spiral through-holes guide air pressure for stronger tactile output while lowering noise in compact haptic structures.

Airflow sensing drives time-varying haptic pulses to convey puff strength clearly without audible or visual feedback that may disturb others.

Wearable haptic guidance uses location-based risk assessment to warn elderly users of hazards before falls and help steer them safely.

Multiple sensors cross-check RFID, visual, and code data to alert users when nearby articles match unwanted characteristics.

Phase-smoothed control of ultrasonic haptic curves cuts parametric audio and compensates slow high-Q transducer response.

Vibration-based wearables paired with an electronic whistle deliver clear wireless instructions in loud games, including for hearing-impaired athletes.

Two haptic actuators split heating and vaping feedback to improve phase recognition while lowering power use in aerosol generation.

Wearable sensors and haptic cues warn of drone direction and proximity, improving early response while avoiding visual-only detection limits.

LiDAR-scanned surroundings are converted into a Peltier thermal image, helping visually impaired users sense object depth and proximity.

A linear shaft and bearing suspension confines haptic motion to one axis, improving vibration uniformity and resisting external pressure effects.

Low-frequency transducers send alert patterns through floors or walls, reaching impaired and non-impaired occupants without loud sounds or bright lights.

Blinking LEDs can be obscured or inaccessible to blind technicians; chassis-transmitted vibration provides tactile device location.

Remote shopping lacks tactile interaction; modular actuators reproduce texture, temperature, and humidity on a feedback surface.

Audio frequency-domain analysis maps sub-band energy to tactile signals, improving feedback accuracy while removing manual tuning.

HJIF lacks frame-accurate media sync; channel timing parameters align haptic effects with video or audio.

A smart ring uses tactile cues to help users with visual or motor impairments align mobile devices for check deposits and NFC interactions.

An adaptive region and movable actuator independently render cutaneous softness and kinesthetic force cues for more realistic touch.

This case uses position-coded vibration fragments to prevent timing drift and preserve synchronized tactile, audio, and visual output.
