Ear Treatment TRIZ Cases
- Speculum with Ports for Minimally Invasive Tympanic Membrane Repair
A speculum featuring dual ports enables minimally invasive delivery of a seal to the tympanic membrane.
- Acoustic Isolation Wall for Active Cooling Noise Management
An acoustic isolation wall divides active and passive cooling zones, allowing lower fan speeds while maintaining component temperature control.
- Charge Pump Biasing Circuit for MEMS Transducer Leakage
Front-end buffer and charge pump generate stable boost voltage for MEMS transducers, canceling leakage effects to maintain constant bias.
- Flexible Extraction Bag with Pneumatic Chamber for Trauma-Free Delivery
An elastomeric extraction device uses pneumatic inflation to envelop the fetus, resolving the contradiction between safe delivery force and injury risk.
- Adaptive Noise Control Gain Scaling Circuit
Independent coefficient adjustment via a biasing portion prevents the adaptive filter from restoring full noise cancellation when users reduce gain.
- Mechanical Vestibular Stimulator Actuator Design
A mechanical stimulator actuator displaces semicircular canals to amplify natural motion signals for the vestibular system.
- Wireless Device Anti-Phase Signal for Call Privacy
A wireless device generates an anti-phase response signal to broadcast around the user.
- Variable Acoustical Damping for Vehicle Engine Sound Control
A variable acoustical damping device adjusts resonance frequency to manage engine intake and exhaust sound levels.
- Hip Joint Inflow Access Cannula with Tapered Design
Segmenting the cannula into distinct diameters reduces tissue trauma while enabling precise instrument placement in deep surgical sites.
- Earphone Acoustic Feedback Loop for Sound Quality Consistency
A hearing aid controller uses a microphone to detect acoustic signals and adjust filter settings for personalized sound delivery.
- Eustachian Tube Stent for Middle Ear Ventilation
Anchoring in the isthmus, a stent device maintains Eustachian tube patency to resolve chronic fluid accumulation without tympanic membrane perforation.
- Bent Needle Inner Ear Fluid Delivery Device
A bent needle device delivers fluid directly to the inner ear through the round window membrane.
- Headset Microphone Housing for Stable ANC
Defined acoustic volume around the control microphone stabilizes the active noise compensation loop.
- Tunneling System Catheter Coupling Mechanism
Segmented coupling mechanisms with nested pins and threads secure catheters, resolving placement reliability issues without increasing device complexity.
- Disposable Speculum with Adhesive for Ear Canal Foreign Body Removal
A disposable speculum features a pressure-sensitive adhesive surface to extract ear canal foreign bodies.
