Roasters/Grills TRIZ Cases

A sliding upper plate and U-shaped frame replace boiling oil with flame-heated plates, improving public-place cooking safety and control.

A grooved cast-iron grill plate vents smoke upward and drains grease away from charcoal for more even heating and cleaner barbecue cooking.

Adjustable slatted sidewalls stabilize bone-down chops and tune heat flow for more even cooking with less supervision.

Back-EMF sensing tracks grill platen movement while the motor is off, helping detect latch failures and over-travel without extra hardware.

An adjustable contact device holds waffle baking plates at a set gap under steam pressure, preventing central defects and uneven sheet thickness.

A removable release sheet covers the cooking surface joint to block grease buildup behind the upper platen while supporting consistent grill compression.

A hinge-integrated torsion spring cushions the upper cooking plate, limiting food crushing while maintaining contact for efficient cooking.

Outer-surface clamping lets the baking mould be removed for thorough cleaning while keeping the heating element and electronics assembled.

Elastic hinge cushioning offsets 40-80% of upper plate weight, keeping food in contact for even cooking without crushing fragile items.

Inclined walls, slits, and protective wings guide fatty drippings into channels, reducing flare-ups and grill soiling during cooking.

A detachable corrugated non-stick plate preserves heat conduction and branding marks while simplifying cleaning and replacement on cooking griddles.

Interlocking stainless steel bars replace tie rods to keep a griddle plate flat, stable, and evenly heated without overheating.

A removable backsplash and extended upper platen back end divert grease from the joint, reducing carbonization, cleaning, and grill failure.

Limiting air-duct thickness reduces turbulence and noise while preserving hot-air speed for faster, more energy-efficient cooking.

An inclined rail, spring lock, and anti-skid slider give the grill continuous height adjustment without slipping during food compaction.

Symmetric inclined arms form concave channels that redirect hot air inward for more even pressure distribution and cooking.

Movable engagement means switch the cooking vessel between rotation and static modes, simplifying hot-air cooking for stirred and fragile foods.

Independent leveling mechanisms keep grill platens parallel and outside the hot zone, improving even cooking, pressure control, and reliability.

A motor-driven rotating pan replaces internal stirring paddles to deliver more uniform hot-air cooking, easier cleaning, and support for larger food pieces.

Reflector housings and absorbance control redistribute infrared heat for more even toasting while keeping crumbs off heating elements.

A bimetal temperature controller and pan locking mechanism keep a double-layer grill closed while enabling adjustable heat for faster cooking.

A handle-operated latch locks the pivoting cooking chamber upright, preventing tipping in storage or transport without a separate recovery plate.

A recessed grill section and friction gasket limit frame heating and slipping, enabling safer use across induction and other cooking hobs.

Permanent magnets hold the food residue tray on the waffle iron, avoiding fragile grooves and making storage and cleaning easier.

Independent control of upper and lower interchangeable cooking plates lets one press handle sandwich toasting and high-temperature grilling.

Independent upper and lower grids with radiant heaters improve cooking uniformity, grill marks, and throughput while reducing burning and sticking.

Inclined one-piece drain channels in detachable grill rods collect fat before it reaches the hearth, reducing flare-ups and easing cleaning.

A port-type burner and baffled chamber convert combustion flow into infrared heat while limiting excess secondary air and pressure.

Solid grill sections above upward gas orifices cut heat loss and gas use while shielding the burner from grease ignition and clogging.

Angled heating and slant boards let hot food roll into a bun while draining juices to a tray, reducing burns, breakage, and mess.

A shallow upper plate and grooved lower plate let batter expand evenly without flipping, reducing air bubbles and pattern defects.

A centrally positioned pivot in a two-shell middle arm cuts swing space, improves stability, and supports heavy contact grill top plates.

An elongated multi-cup raclette layout uses zoned access and thermal reflection to limit heat loss while serving more guests comfortably.

Raised magnetic pedestals heat only the cut bun surface to caramelize the interior while preserving texture and reducing sauce soak-in.

A hotter smoke cup and cooler grill plate let one heater generate flavoring smoke while cooking food without burning.

Angled external slides move fats and food solids into an outside receptacle, cutting grill flare-ups, smoke, and hidden ember risks.

A perforated, low-conductivity shield under the drip tray blocks hand contact with hot surfaces while keeping the electric grill easy to clean.

A ceramic-coated raised-rail grill grate solves high-heat sticking and cleanup issues while delivering even searing and indoor oven grilling.
