Biological Material Testing Procedures TRIZ Cases
- 3D Culture Plate Well Structure for Uniform Hydrogel-Free Spheroids
A stepped main-sub well layout enables hydrogel-free 3D culture, stable spheroid formation, and lower pipetting disturbance.
- Cell Suction Chip Holder for Self-Aligning Needle Positioning
A movable chip container holder corrects shaft-to-chip misalignment, enabling precise needle positioning and faster cell suction.
- Cell Suction Chip Alignment Using a Movable Container Holder
A movable chip container holder self-corrects axial misalignment at connection, enabling precise needle-tip alignment for efficient cell suction.
- Fermentation Vessel Filter Assembly for Sediment-Free Pressure Release
A chambered filter assembly keeps sediment away from pressure release valves, allowing CO2 escape and steadier fermentation quality.
- Handheld Mold Detection Device with Integrated Immunological Testing
A handheld measuring device integrates collection, buffer, and immunological units for rapid on-site mold analysis.
- Cell Culture Microwells with Rounded Tips for Uniform Spheroids
Rounded microwell tips guide cells into uniform spheroids, preventing uncontrolled growth on flat edges.
- Self-Centering Gripper for Automated Cell Therapy Manufacturing
A self-centering gripper uses contoured elastic members to automatically align and secure fluid connections during automated cell therapy production.
- Cell Detachment Device with Piezoelectric Feedback Control
Piezoelectric feedback detects vibration state to prevent cell damage while ensuring efficient detachment.
- Automated Liquid Sampling Device with Clutch-Driven Cannula
A device for withdrawing liquid samples from vials uses a clutch mechanism to drive a cannula through closure caps.
