Prosthesis TRIZ Cases

Lever-actuated dual clutch mechanism generates high pressure for advancing bone cement, reducing extravasation risk during vertebral procedures.

Interrupted threaded protrusions engage discontinuous internal holes for quick, accurate assembly of modular orthopedic instruments.

Adjustable prosthetic socket modifies stiffness and shape through an integrated peripheral device.

An interlocking knitted mesh implant segments fibers by degradation rate to transfer load gradually, preventing abdominal wall incompatibility.

Perforated insertion structures in a fluid manifold deliver materials deep into cancellous bone, reducing tissue damage and improving implant stability.

Ball and socket connection enables universal rod positioning, resolving the contradiction between precise alignment and device complexity.

Matching fiber-reinforced plastic thermal expansion eliminates rattling play between prosthesis socket and adapter element.

Infusing PEEK into coralline ceramic channels resolves the trade-off between load-bearing capacity and tissue integration in spinal fusion implants.

Segmented pouch structures in a modified tissue graft resolve the contradiction between fluid egress and constrictive stress tears.

Polyacrylic acid accelerates extracellular matrix synthesis in temperature-sensitive electrospun scaffolds, reducing culture time and cell requirements.

Dual-zone silicone elastomers accommodate residual limb changes while a lubricious coating reduces friction during donning.
