Prosthesis TRIZ Cases
- Bone Screw Porous Structures for Sacroiliac Fixation
Porous surfaces, internal channels, and overhanging threads support bone ingrowth and sacroiliac fixation through DMLS titanium printing.
- Bone Cement Extrusion Thread Design for Reduced Manual Force
High friction makes large-volume bone cement dispensing difficult; controlled thread geometry reduces manual force and supports consistent mixing.
- Flexible Prosthetic Socket With Edge-Bonded Rigid-Flexible Zones
Edge-to-edge bonding joins a rigid frame and deformable layer to reduce socket weight while accommodating limb volume changes.
- Single-Piece Abdominal Hernia Mesh With Inguinal Flaps
Distinct upper and lower mesh sections with inguinal flaps provide full abdominal wall coverage while simplifying reconstruction with one implant.
- Groove-and-Projection Joints for Orthotic and Prosthetic Devices
A groove and matching projection create a detachable joint that resists pulling and bending forces across materials with different elasticities.
- Ventilated Prosthetic Socket With Localized Moisture Venting
Porous vent elements move air and moisture through the socket wall, helping manage sweat and heat while preserving load-bearing support.
- Low-Viscosity Photo-Curable Resins for Tough Orthodontic Aligners
Oligomers above 3,000 Da and limited hydrogen bonding preserve low-viscosity printing while improving aligner toughness.
- Orthotic Clamping Interface for Secure Prosthesis Attachment
3D-scanned, CAD-matched clamping interfaces use adjustable tension and localized friction to prevent orthotic migration on prostheses.
- Amputation Stump Casting Liner for Uniform Radial Pressure
A longitudinally expanding liner reduces circumference to apply uniform radial pressure during amputation-stump molding.
- Bioresorbable Skin Substitutes with Localized ASCs
Scaffold sponges localize ASCs in chronic ulcer wounds while releasing healing factors from a bioresorbable skin substitute.
- Hyaluronic Acid–Collagen Biomaterial for Lung Tissue Regeneration
Loss of pulmonary extracellular matrix limits cell-based repair; a hyaluronic acid–collagen scaffold supports viability and alveolar regeneration.
- Implantable Mesh Introducer With Protective Cape for Trocar Delivery
A flexible polymeric cape and rigid push stick protect implantable mesh from grasper damage and contamination during trocar insertion.
- Cape-Shielded Implantable-Mesh Introducer for Small Trocars
A protective cape surrounds the mesh during trocar insertion, reducing direct-tool damage and contamination while fitting smaller trocars.
- Reversible Metal and Graphite Adhesion to Hydrogels and Tissues
Low DC fields bond metals or graphite to hydrogels and tissues without adhesives, while polarity reversal can enable release.
- Cell-Sheet Immunoisolation Device with Porous Membrane-Hydrogel Layers
A porous membrane and hydrogel cover a cell sheet to shorten diffusion distance while supporting nutrient transport, immune isolation, and transplant durability.
- Self-Gripping Hernia Prosthesis for Stable Tissue Positioning
Protruding tissue grips and barbs secure hernia repair fabric, reducing reliance on sutures or staples during tissue integration.
