Controlling Members TRIZ Cases

A ball-ramp detent alignment mechanism gives pilots tactile cues on control stick position, improving detent awareness and reducing confusion.

Electronic output limiting replaces mechanical throttle stops to control small-boat horsepower accurately and simplify regulatory compliance.

A movable foot cradle replaces multiple surgical foot switches, reducing strain and letting surgeons keep focus on the operative site.

A height-adjustable pressing module lets mobile robots operate standard elevator buttons without direct system access, enabling autonomous floor travel.

Real-time direction and orientation cues on a joystick display help operators control remote or virtual targets when line of sight is lost.

A rotating ball, roller, or bearing at the cam-rod interface cuts friction and wear in excavator pedal valves for smoother pressure control.

A single grippable controller combines yaw, pitch, and roll input while a second control handles peripherals with simpler response-curve setup.

A fulcrum-driven plate mechanism changes the lever mounting angle, making bolt loosening easier when the lever sits close to the base.

A geared rotary oil damper and shaft-based optical sensing improve knob feel while reducing free play, vibration, and motor size.

A switchable excavator pedal mechanism changes between front/rear, front-only, and fixed modes to avoid manual pin and bolt work.

An elastic ring and two-part grip secure a crank handle end without machining or special tools, cutting assembly time and cost.

A Belleville washer disengages the flywheel at a preset torque to prevent abutment wear while still allowing higher unscrewing torque.

A rotating magnetic puck and Hall sensor separate sensing from shaft motion, improving joystick durability without losing position accuracy.

A removable monobloc pedal module integrates adjustment and braking functions to cut rudder bar complexity, weight, and maintenance effort.

A brake lever angled out of the trigger plane spreads finger pressure, reducing pain and improving control in repeated RC transmitter braking.

Separate linear and rotary control elements let one hand input drive multiple attachment motions with less operator skill and less complex joystick movement.

A mechanical lock stops the UAV controller screen at a safe angle until the joystick is folded flat, preventing closure damage.

A dash brace links separated pedal brackets across the steering column hole to strengthen the cabin front wall and resist collision intrusion.

A press-fit metal stamping reinforces an injection molded rake lever, cutting insert-molding cost and part complexity while preserving lock-unlock function.

An intermediary spline adapter lets installers fine-tune valve handle angle, cutting off-position misalignment from coarse tooth indexing.

A magnetically attachable knob uses wireless control and inductive charging to let users operate loudspeaker functions from different locations.

Attachment-aware removable input controls replace multiple buttons by mapping functions to location, simplifying electronic interfaces.

A rotary damper adds tactile resistance to an electronic trolling motor foot pedal while keeping steering switches accessible and harder to trigger by accident.

An integrated cyclic housing combines actuators and force sensors to save cockpit space while simplifying rotorcraft installation and maintenance.

An electrical lever, gear, and angle-sensor layout replaces bulky control cables to keep side-mount engine controls compact and easy to operate.

A stationary bumper in the BTSI lock pin cavity replaces moving O-rings to cut park lock noise without hurting solenoid sensitivity or efficiency.

An internal grip fulcrum and universal-joint support cut hand effort while keeping working machine operation stable during shaking.

Separate pivotable lever elements share one axis to actuate multiple bicycle switches and expand rider control options in a compact assembly.

Separate thumbwheel and joystick controls simplify VTOL and forward-flight transitions while altitude-based limits improve novice pilot safety.

A joystick handles steering and longitudinal motion while separate pedals manage braking and attitude angles for simpler sports car control.

A two-part rotary handle with a user-operated alignment unit enables stepless positioning of sanitary valve controls despite discrete coupling.

Separate pivoting control elements actuate multiple switches in a compact handlebar layout, expanding bicycle functions while reducing finger entrapment.

Complementary splines, friction surfaces, and distributed sealing elements secure disc position while reducing leak paths and assembly complexity.

A gripper, concave finger trenches, and cradle make CMM control easier to hold, reducing operator fatigue and improving measurement precision.

An embedded light module with a fixing plate and transparent cover lets a remote controller work at night while protecting the LED from damage.

Fast tilt-dump lever switching disables bucket auto positioning, preventing unintended attachment motion while preserving precise manual control.

An outer shift pedal linked to an inner detection unit preserves rider knee-grip while shielding the sensor from dust, mud, and debris.

A float-and-catch selector lever locks shaft rotation when a detent pin fails, giving clear mechanical failure indication and safer operation.

Magnetic viscous fluid creates controllable rotary resistance without a motor, improving manipulation feel while keeping the mechanism compact.

Combining boom tilt, rotation, and telescopic input into a rotatable joystick reduces control complexity in aerial ladder operation.

Separating boom rotation and inclination from telescopic control makes aerial device operation more intuitive, ergonomic, and precise under stress.

A spherical collective grip lets pilots reach auxiliary controls with fingers and thumb without releasing the lever during flight.
