Control Devices TRIZ Cases

A computing system disables steering and braking inputs during autonomous operation to resolve the contradiction between user control and operational safety.

Elastomeric hollow fibers pump blood via elastic deformation, eliminating external pumps and reducing filling volume for implantable use.

Varying tubing diameters and a submerged flow diverter reduce shear stress on platelets, extending usable time of fresh human blood for accurate device testing.

Electronic control unit detects sensor faults and displays operable driving assist systems on a segmented interface.

An atrial assist device pumps blood from the left atrium into the left ventricle, reducing left atrial pressure and enhancing cardiac output.

A heat distributor thermally connects a pump motor to the housing wall, reducing blood damage from excessive heat generation.

Segmenting the device into an internal impeller and external management unit reduces surgical invasiveness while enabling long-term blood flow regulation.

A wireless ultrasound transcutaneous energy transfer system delivers continuous power to bio-implantable devices using a two-dimensional transducer array.

Motor controller uses frequency domain analysis of drive currents to differentiate pump occlusion from physiological conditions without extra hardware.

Variable speed impeller generates pulsatile blood flow, suppressing health deterioration during long-term use.
