Animal Feeding Devices TRIZ Cases

A rotating food-pushing chamber alternates two pet foods into one bowl, avoiding mixing while supporting more balanced feeding.

A layered rabbit litter box separates the animal from waste, limits litter scatter, and cuts maintenance cost with reusable and disposable parts.

An RFID aerial across the roof and sidewalls improves authorized pet detection while the housing and cover layout blocks unauthorized feeding.

A two-chamber hopper, rotating disc, and IR chute sensor improve pellet dispensing reliability while reducing jams, damage, and cleaning effort.

A conveyor lifts pet food from a lower tank to a higher outlet, improving feeding comfort while reducing buildup and blockage.

Detachable wet and dry single-serving containers make pet feeding easier to handle, mix, and serve without extra bowls.

Sealed bowl-shaped wet food pods enable timed dispensing while limiting spoilage, mess, and cleanup in automated pet feeding.

Nested sealed pods let wet pet food stay fresh until mealtime, then drop for feeding and closed disposal to reduce spoilage and mess.

Off-device instructions in a DHT let blockchain-connected IoT nodes stay lightweight while gaining secure, remotely updated control.

Force sensors on a universal chassis let one agricultural robot swap functional units, measure load accurately, and handle feeding, cleaning, and transport.

A helical height-adjustable climbing column expands reptile activity space, reduces crawling, and adds an umbrella structure to prevent escape.

Motor-driven radial chambers and a locking pin limit pet access to one portion at a time, reducing overeating, damage, and programming difficulty.

Motorized pinching and squeezing dispense wet feed in precise portions while reclosing the bag neck to limit waste, oxidation, and contamination.

Environmental sensors and calibration algorithms correct feed bin weight errors from temperature, humidity, wind, and vibration.

Low-voltage conductive bands repel crawling insects from pet food without killing them, avoiding water-barrier upkeep and contamination.

Pointed plates and rotating bars block raccoons from jumping or gripping the feed trough while keeping feed accessible to intended wildlife.

Controlled nipple vibration helps infants develop suck-swallow-breathe coordination for bottle feeding and soothing while limiting added complexity.

A weighted balance base and adjustable food clip combine rolling and swinging play with controlled food release to train slower pet eating.

A sliding-lid feeding box passes through cage mesh to deliver food or water while reducing bites, escapes, spillage, and contamination.

A single motor drives both feed transfer and feeding-head motion through gears and a crank, enabling hygienic, controlled pet feeding.

Motor reversal lets one gear train alternately move the feeding head and rotate the transfer portion for hygienic, controlled single food intake.

Stacked trays in an insulated feeder keep perishable pet food cold before and after dispensing, cutting waste in a compact footprint.

A robotic gripper, can opener, and bowl transfer layout automate canned pet feeding, serving fresh food and disposing of used bowls.

A sealed hopper and pressurized air blast let one person refill safely, keep animals out, and dispense feed accurately away from the feeder.

A reversible coupling, rotor, and auger layout improves feed dosing precision while enabling clean replacement and more complete emptying.

A hinged cap and semi-removable dispenser enable one-handed lickable treat delivery, secure sealing, and integrated clicker training.

A movable feed displacer shifts feed along the fence so animals can eat edible portions before only contaminated rest feed is removed.

Gravity-driven grid panels compress hay and restrict access, slowing equine intake to reduce waste and overeating.

Air-pressure ejection replaces noisy springs and jam-prone gears, while gas cleaning clears food debris from the ejection channel.

Remote food, water, camera, and two-way audio functions let owners monitor and comfort pets away from home while easing separation anxiety.

A gear-rack lid mechanism automates feeder opening to separate pets during meals, reducing food grabbing, spillage, and dampness.

A smooth roller guard at feed egress points stops pests from gaining grip, reducing feed waste, dispenser damage, and maintenance.

Splash-proof walls, a partitioned bowl rack, and a lower base plate contain food and water spills while keeping pet feeding easier to clean.

A detachable flared shield contains pet food spillage while preserving bowl access, low cost, and a compact feeding footprint.

Visible multi-level ramps let cats track and advance treats step by step, turning retrieval into a repeatable problem-solving task.

A dual-hopper screw feeder and offset food-water layout prevent clogging and water contamination while dispensing timed food portions.

Nesting cage bases automatically disengage attached components, cutting sorting labor, improving nesting density, and simplifying recycling.

Dynamic feed timing uses free milking capacity and animal ID to prevent concentrate deficits without reducing robot throughput.

A curved front, higher rear wall, and rear protrusions guide eating posture, reduce strain, and keep food from spilling during feeding.

Separate food bins and matched feeding assemblies let one feeder dispense different foods independently, avoiding contamination and discomfort.

A drying bin keeps stored pet food dry while the dispensing mechanism delivers timed, measured portions to prevent spoilage and misfeeding.

Opposed cutting members sever the feed string without lateral shift, improving portion accuracy and reducing spill on mink cage top walls.

Domed guide plates and a chute control member help a broadcast feeder block varmints, reduce feed loss, and simplify hopper removal.

Differing end diameters keep the toy rolling in a curved path, confining treat dispensing to preferred surfaces and reducing mess.

A side press button lifts the food container upward to dispense treats smoothly while preventing outlet clogging and container sticking.

A weighted sliding cover sets an access-force threshold so target animals reach toxic bait while non-target species are blocked or deterred.
