Belleville-Type Springs TRIZ Cases

A protrusion-first spring washer limits overtravel in a variable flow valve, reducing plastic deformation, collision noise, and reliability loss.

Circumferential spring arms preload the worm gear bearing evenly to cut steering noise, avoid tilting, and absorb axial play.

By making the joined portion flat and orthogonal to the spring axis, end alignment stays stable and precise welding works on general-purpose machines.

A conical disk, ring spring, and damper ring tune shoe bounce frequency and damping to better match gait and absorb impact.

A compression washer adds axial force and thread friction to stop turnbuckle back-rotation and prevent subsea well string disengagement.

Stacked cup springs in a wastegate biasing member reduce oxidation, wear, and relaxation under hot exhaust gas, extending service life.

A shape memory spring drives the plunger for compact, metered drug delivery while simplifying cartridge replacement and reducing contamination risk.

Springs built into the HDD top cover absorb VCMA magnetic reaction forces, reducing cover deformation, data errors, and enclosure leaks.

A spiral-wire and warpable buffer structure isolates vibration while preventing protrusion, collision, and unusual noise in the connector.

A resilient spacer reindexes a hydrant nozzle cap for antenna alignment while preventing gasket blockage of the drainage path and pressure relief.

A hole at the claw tip cuts centrifugal-force-driven deformation, keeping disc spring load characteristics stable across changing shaft speeds.

A sealed dead space between the heat shroud and spring lowers spring temperature and keeps the variable-nozzle cartridge correctly located.

Stacked spiral and warpable buffer members isolate vibration while preventing wire protrusion and collision damage in a connector.

A load-triggered ring and spring let a stabilizing surface stay extended, then retract under high downhole loads to limit reactive movement.

Layered star springs with an anti-rotation element bundle closing force in a damping valve while reducing spring stress and extending service life.

Modular rod, plate, and coned disc spring adjustments let press dies tune stroke and blank holding force without reprocessing.

A symmetrical tabbed spring washer prevents misalignment and gap drop-in during transmission assembly, reducing wear and component damage.
