Solid Waste Disposal TRIZ Cases
- Secondary Battery Water Vapor Treatment for Lithium Deactivation
Low-temperature water vapor deactivates metallic lithium in secondary batteries, cutting energy use and preserving valuable material recovery.
- Dry Smelting Flux Composition for Low-Phosphorus Battery Metal Recovery
Calcium-based flux control in dry smelting removes phosphorus during waste Li-ion battery melting while preserving copper, nickel, and cobalt recovery.
- Electrochemical Generator Opening in Ionic Liquid for Safe Discharge
Immersing charged electrochemical generators in ionic liquid enables discharge and insulated opening while avoiding explosions and toxic fumes.
- Ionic Liquid Battery Discharge for Safe Recycling
An ionic liquid with conductive powder enables controlled battery discharge, avoiding explosions and toxic fumes during recycling.
- Flat Panel Display Disassembly for Safe Automated Recycling
Automated FPD characterization and guided cutting separate screens and hazardous parts for safer, higher-throughput recycling.
- Battery Waste Heat Treatment to Prevent Leaching Foam
A two-step atmosphere heat treatment limits electrolyte combustion and suppresses acid-leaching foam to improve cobalt, nickel, and lithium recovery.
- Integrated Air Switch Assembly for Easier Food Disposer Installation
By integrating the air switch module into the disposer housing, this case cuts under-sink connections and simplifies power control installation.
- Flow Cell Reducing-Agent Regeneration for Battery Recycling
Forced-convection flow cells regenerate reducing agents separately from leaching, cutting energy use, reagent demand, and recycling cost.
- Triboelectric Particle Source Without High-Voltage Charging
Airflow through concentric cylinders charges dust by friction, replacing high-voltage particle charging with a simpler, lower-cost structure.
