Ear Treatment TRIZ Cases

A vascular filter wire dispenser deploys a coiled filter through a needle for minimally invasive clot capture.

A micropump-driven cannula pierces the round window membrane to deliver compounds directly into cochlear perilymph.

A binaural noise reduction scheme combines spectral gains from multiple stages to enhance audio signals in complex environments.

An asymmetric transducer arrangement with signal equalization generates opposing inertial forces to cancel mechanical vibration on the speaker baffle.

A drug delivery device with an intra-cochlear portion containing a drug eluting polymer material releases therapeutic drugs directly into inner ear fluids.

A middle ear prosthesis integrates silver nanoparticles into thermoplastic polymer granules to provide localized antimicrobial protection.

Segmented housing isolates the active muffler loudspeaker from exhaust gases to prevent thermal damage.

Merging the pulling wire with the force sensor connection reduces catheter diameter, enabling deeper cochlear access for implant electrodes.

A vehicle cabin noise cancellation system extends previous mode sound frequencies to mask exhaust pop noise during engine cylinder switching.

A diaphonic valve system converts acoustical vibrations into static pressure using a synthetic jet mechanism.

Adaptive directional microphone employs FIR filter bank to minimize interference powers while balancing signal quality against increased microphone noise.

A tone processor detects instability indicators in the feedback signal to dynamically adapt the noise canceling system.

A catheter with a dynamic curved tip and straightening device advances through the femoral vein to engage an implanted vascular filter.

Flexible whisk-like bulbous ends on a disposable device remove ear wax without pushing it deeper or stripping the natural protective barrier.

Segmenting the device body into holding sections with variable guide slots eliminates spacer plate logistics while maintaining thickness precision.

A flexible ear canal delivery device uses a liquid metering valve to ensure precise volume control during administration.

An elongated swab applicator uses adhesive-covered through openings to capture debris from hard-to-reach cavities.

Antiphase airflow directed into fan exhaust reduces turbulence and attenuates acoustic noise in high-performance computer systems.
