Fuel Supply TRIZ Cases

A force-limiting clutch and decoupling actuator reduce injury and damage risk while preserving manual cover access during power failure.

Preloading fasteners into fuel tank bands before lifting reduces misalignment and dropped bolts during vehicle fuel tank installation.

A welded holder and metal-plastic connector structure cuts vehicle fluid tank weight and cost while maintaining stability and leak resistance.

A stabilizing rod and movable brackets spread tank loads and torque across the chassis to improve durability, balance, and space use.

An over-center linkage locks the tank flap shut without power, while manual emergency release preserves access and stable positioning.

A stepped holder with an inclined guide region and spacer lets the fuel filler neck deflect under lateral force while avoiding deformation.

A locally deformed tank opening gives outside access to the filler neck weld seam, improving weld quality and reducing fuel leakage risk.

A remote motor and pulling device open and close the fuel filler flap while freeing space at the tank recess for more flexible vehicle packaging.

A nozzle-guided protrusion lets the fuel nozzle open the flap with less force while a biasing spring keeps the fuel hole tightly sealed.

A clamped top-and-bottom bracket layout lets the mower fuel tank expand and contract without fastener stress, reducing leaks and replacement time.

A sealed gear region and galvanic-compatible coating prevent corrosion and fuel leakage in aircraft external tank quick disconnect valves.

A spring-biased tilting lever lets an EV charge port door release under forced loads, protecting the actuator and linkage from breakage.

An elastic-biased lever lets a vehicle charge port door release under break-in loads, preventing excessive actuator stress and breakage.

Angled walls, securement tabs, and automated fuel transfer add 4.6-7 gallons to off-road vehicles without overfilling the main tank.

An inclined guide rail steers retention means into the assembly slot, simplifying pivoting trim installation and reducing panel misalignment.

A threaded receptacle mounted inside the fuel panel holds the cap securely during fueling to prevent spills, damage, and sharp flange exposure.

Integrated dial indicators on the gas cap show fuel mix ratio, octane level, and fill date to prevent two-stroke fueling errors.

A multi-part drop-and-go bracket mounts vehicle fuel tanks securely on the assembly line, cutting installation time and avoiding retrofit work.

Three brackets in a triangular support layout spread jolting loads to protect vehicle-mounted containers and simplify removal.

A separate actuating element triggers the push-push mechanism so a sealed vehicle flap opens without the initial inward movement.

An extended arm-side restriction portion enlarges lid contact width, helping the linkage hold a stable open position with better rigidity.

Partition ribs split the tank into grid cavities to weaken fuel surge, reduce weld cracking risk, and raise tank rigidity.

Separate overpressure and underpressure bypass paths relieve filler-pipe pressure without venting the sealed chamber, cutting vapor leaks.

A lower side suction port and separate drain layout help work vehicle fuel tanks draw fuel easily while keeping impurities away from the engine.

A multi-part interlocking bracket mounts vehicle fuel tanks to the chassis quickly and securely without extra fasteners or line removal.

Integrated LIN slave control with PID feedback stabilizes vehicle lid and hidden handle actuation while reducing harness voltage drop.

A fixed-and-sliding tank mount accommodates hydrogen tank expansion, cutting stress on fuel pipes and chassis parts while improving durability.

A force-limiting clutch and torsion spring decouple the vehicle cover drive under overload, preventing injury, damage, and lockout during power loss.

Sequential punch forming creates an integrated fuel filler funnel with controlled wall thinning, cutting assembly steps and manufacturing cost.

An electrical heating element keeps the capless filler flap from freezing shut, preserving easy refueling in low temperatures.

A double-seal fuel inlet uses a water-catching section to intercept drain-passed spray and keep high-pressure wash water out of the cabin.

A spring-loaded multi-link flap with Bowden cable actuation lowers operating force while securely holding vehicle body openings open or closed.

Curved panels sliding on a spherical frame close vehicle filler access while cutting package space and enabling remote operation.

Guide rails inside a fuel container let internal components slide to accessible positions, reducing maintenance difficulty in complex layouts.

A movable release slide and latching stop surfaces admit truck and car diesel nozzles while blocking smaller gasoline nozzles.

Hooking-tab metal clips reinforce fuel tank mounting brackets to maintain attachment in fire without adding excess weight or taking tank space.

A roof-mounted CNG tank enclosure with an internal chassis enables safer gasoline-to-CNG conversion across vehicle models while limiting drag and leaks.

Multiple striking fins and sound generators create varied locking sound intervals in a fuel cap without adding separate mechanisms.

A dual-bracket canister mount shifts vehicle assembly work above the frame while preserving secure fastening and easier maintenance.

A multi-pattern mounting plate lets one fuel fill adaptor fit different fuel tank neck layouts, reducing adaptor changes and installation time.

Using same-species recyclate and virgin plastic, this tube structure preserves pressure and fluid resistance while reducing virgin material use.

A same-polymer recycled and virgin plastic tube structure preserves adhesion, strength, and barrier performance while cutting virgin material use.

A motor vehicle lid lock uses a spring-loaded central pin to detect locking pin position via magnetic sensing.

Merged actuator and short actuating arm reduce component count and simplify assembly for compact vehicle flap locks.
