Ion Exchange Regulation/Control TRIZ Cases
- Dual-Chamber Filter Cartridge With Bypass Water Path
A separate auxiliary inlet bypasses the first chamber, enabling two-stage ion exchange, tighter water composition control, and compact cartridge size.
- Buffer Preparation Using Conductivity Feedback for pH Control
Conductivity replaces direct pH sensing in buffer mixing, enabling faster, cleaner feedback control with less calibration and temperature correction.
- Ion-Exchange Syringe Assembly for Comfortable pH-Adjusted Injection
This case uses ion exchange material during ejection to shift stored solution pH toward physiological levels while preserving shelf life.
- Ion-Exchange Resin Copper Extraction for Solvent-Free PCB Etching
This case replaces hazardous liquid extraction with regenerable resin beds for compact copper removal from PCB etchants.
- Ion Exchange Resin Cartridge Water Content Reduction for Purification
Inert gas drying lowers ion exchange resin water content to 90-97% saturation, minimizing initial blow effluent volume and preventing metal contamination.
- Onium Hydroxide Recovery via Surfactant and pH Control
Surfactants and pH control prevent photoresist precipitation, maintaining ion exchange capacity during onium hydroxide recovery.
- Control Valve Regeneration Frequency Adjustment Mechanism
A control valve uses a dual meter disc assembly to adjust regeneration initiation slots externally.
