Metal-Working Apparatus TRIZ Cases
- Automatic Towel Dispensing With Perforation Learning Control
A motor and sensor learn towel perforation spacing, then extend and retract toweling to dispense accurate lengths across towel types.
- Compound Lever Arm Assembly for Low-Fatigue Food Processing
A two-arm compound lever amplifies manual input force, speeding food squeezing while reducing operator fatigue.
- Rounded-Tip Dispenser Cutter for Safer Web Tearing
Rounded protrusions with cutting edges between them let centre-fed web material tear cleanly while reducing hand injury, splintering, and dust.
- Dual-Action Food Processor Dicing for Lower Torque Cutting
A two-stage cutting sequence pre-slices food before grid dicing, cutting torque, current draw, noise, and heat in food processors.

- Rotary Juicer Pressing and Filtration for Soft Fruit Extraction
A rotating pressing member and filtering wall raise juice and coulis yield from soft fruits while keeping the juicer compact and easy to clean.
- Clamshell Heat Exchanger Passageway for Compact Heat Recovery
A low-aspect-ratio clamshell passageway boosts furnace heat recovery in tight HVAC spaces while remaining manufacturable from formed sheet metal.
- Bezier Rotor Blade Tip Planform for Stall and Noise Control
A Bezier-shaped rotor blade tip delays stall and compressibility effects while improving hover efficiency and reducing acoustic noise.
