Gearing TRIZ Cases

Facing frustoconical pivots and a spring-loaded dual-arm layout keep serpentine belt tension stable across reversible drive modes and reduce slippage.

A lost-motion backup transmission keeps steering rack power assist available after drive belt failure while protecting the secondary path.

Acoustic threshold sensing, bridgeplate locking, and LED warnings prevent unsafe platform descent during wheelchair loading.

A geared wrist adapter converts rotary input into linear end effector actuation, enabling surgical tool compatibility without redesigning the instrument.

Nested segmented pulleys vary effective diameter to deliver wide speed adaptation with low backlash, lower eccentricity, and compact transmission size.

Rolled internal threads with a chamfered crest prevent bulge interference, helping the plunger move smoothly and absorb chain looseness.

An eccentric non-circular cam guide improves oscillating shear blade motion for cleaner cuts, lower friction, and varied branch thickness.

Optimized rim thickness and tooth profile angles let a strain wave gear carry higher torque in less radial space while reducing wear, jamming, and noise.

Two motors and a brakeable planetary gear train keep linear motion available after a motor fault while alternating use to reduce wear.

A snap-fit return tube and retention clip secure the steering ball nut assembly without welding or screws, reducing distortion and assembly defects.

Independent shaft coupling replaces gear linkage between the photosensitive drum and developer roller to stabilize rotation and improve print quality.

A single low-profile wedge and overhang tool guides stretch fit belts over marine engine pulley flanges without pinching, cutting tool count and cost.

A dual-motor screw drive and clutch let a press brake switch from fast ram approach to high-torque bending with less complexity and smaller motors.

A thrust bearing and axial biasing member replace radial support to shrink spline nut shaft diameter while preserving smooth rotation.

A tapered-slot guide prevents telescope actuator rotation under misaligned loads while still allowing steering column rake adjustment.

A decoupled focus cell translation assembly uses preload-guided members and bearing compensation to limit binding, friction, and boresight drift.

Tube-side abutment portions lock the first and second circulation members in circumferential alignment for smoother ball circulation and a compact nut structure.

A cam-driven linkage raises and nests a notebook keyboard, reducing closed thickness while keeping a usable typing position.

A stationary-to-rotating channel layout feeds lubricant between the spindle and nut, enabling relubrication during operation without disassembly.

A passive lock uses actuator overtravel and motor-driven gearing to hold a thrust reverser retracted without a separate locking actuator.

By lowering primary target pressure when pump capacity is tight, this CVT control approach holds maximum ratio and prevents belt slippage.
