Surgery TRIZ Cases
- Magnetic Port Locator Assembly for Precise Subcutaneous Target Alignment
Reversed-pole locator magnets and a guide housing align hidden subcutaneous ports accurately, even through thick tissue and high-BMI anatomy.
- Packaged Image Sensor Through-Hole Layout for Flexible Endoscopes
A substrate through-hole fixes pipe-to-sensor alignment, simplifies demolding, and enables a smaller endoscope bending radius.
- Heat-Expandable Closure for Flush Sealing Vehicle Body Openings
A heat-expandable sealing element on a pre-assembled closure securely seals vehicle body openings during thermal coating while keeping a flush finish.
- Display Panel With Integrated Eye Fundus Imaging and IR Sensing
Integrated light-emitting and light-receiving elements on one display panel enable eye fundus imaging, precise eye monitoring, and lower-cost manufacturing.
- Optical Unit Lens Barrel Position Sensing Without Adhesive Stress
A base member isolates the magnetic sensor from adhesive stress, improving lens barrel position detection accuracy in a voice-coil optical unit.
- Endoscope Signal Cable Shield Fixing for Flexible Distal Bending
By fixing the shielding layer between insulating layers, this endoscope cable preserves distal flexibility, avoids shorts, and keeps diameter low.
- Endoscope Image Pickup Assembly With Resin-Based Focal Alignment
A cured transparent resin sets the optical interval so the image-forming plane matches the sensor surface in compact endoscope imaging.
- Endoscope Switch Dome Structure Against Autoclave Misactivation
A tensioned dome switch structure resists pressure-driven cover retraction during autoclave sterilization while preserving reliable endoscope operation.
- Flexible Catheter Detection Circuit for Reliable Micro-Welding
A dual-sided circuit board and cavity support improve catheter detector welding strength, cable stability, and signal transmission in tight packaging.
- Alcohol Measuring Device Face Verification Against Sample Manipulation
Reference face images unlock the alcohol measuring device only for the verified user, reducing remote sample manipulation and false alarms.
- Capsule Endoscope Locomotion Using Electromagnetic Impact Propulsion
Electromagnetic rotor impacts generate stronger propulsion in capsule endoscopes, improving speed and position control against digestive friction.
- Pulsed Electric Discharge Voltage Feedback for Stable Forming Pressure
Breakdown-voltage feedback adjusts each discharge shot to keep energy-to-pressure conversion consistent in electrohydraulic forming.
- Endoscope Handle Force Feedback for Controlled Bending
A force sensor and motor-controlled sliding block adjust bending wire tension to prevent excessive penetration and improve endoscope handling.
- Endoscope Connector With Inflatable Locking for Stable Plug Retention
An inflatable body inside the connector recess boosts plug retention under cord pull while allowing easy release and stable electrical contact.
- Endoscope Optical Unit Magnetic Layout for Precise Two-Focus Switching
A localized magnetic body member stabilizes barrel motion and alignment, enabling precise two-focus switching in endoscope optics.
