Controlling Members TRIZ Cases

A foot-raised lever and detent switch let drivers shut off the engine from the accelerator while keeping both hands on the wheel.

Magnetorheological fluid and servo torque control give a vehicle rotary knob precise haptic feedback and stable mode selection.

A single vehicle knob switches between detented and smooth rotation, letting users control closed-loop and open-loop functions with clear tactile cues.

A nonlinear counterforce profile and decouplable coupling element preserve brake pedal feel while preventing blockage in brake-by-wire systems.

A movable actuator changes spring extension between two bracket positions, giving safe mode switching and precise pedal feel at lower complexity.

A tangential steering-wheel lever layout preserves multi-function operability while preventing contact with the driver's leg at full lock.

A flexible translucent film uses reversible deformation and selective backlighting to add hidden controls, haptic feedback, and on-demand illumination.

A relay stores lead-vehicle waypoint history and sends only needed path data to joining followers, easing communication load in platoons.

A relay-gated dual control module setup prevents unintended vehicle component actuation while improving control flexibility and reliability.

Electro-permanent magnet actuation smooths long-document scrolling, cuts repeated wheel input, and stops automatically at target positions.

Travel sensing at the pivot bearing and force sensing behind the pedal improve braking intention detection in compact brake-by-wire modules.

A radially inserted light guide lets the rotary knob be painted first, avoiding masking and costly two-component molding.

A modular press-fit connector carries power and data for smart lighting scenes while avoiding switch-off inoperability and complex installation.

A sensor-triggered selector rises from a flush vehicle audio surface for tactile control, then retracts to preserve interior aesthetics.

A cam-linked movable button module lets vehicle controls appear only when needed, reducing visible buttons, interior clutter, and operation errors.

A longer magnet-side lever arm amplifies tiny lateral input motion, enabling more accurate magnetic flux sensing in compact controls.

A dual-pedal parking brake uses an over-center linkage to replace tall hand levers, cutting parts and material on stand-on terrain vehicles.

A multi-joint carrier replaces separate seat-side rails to adjust lever height and reach together for better driver comfort and easier operation.

A root-thickened curved support wall disperses assembly stress, preventing breakage while improving pull-up load strength.

A gap below the organ-type pedal pad lets sand and pebbles roll out, preserving depressibility and braking safety.

An adjustable connecting rod shifts piston start position to tune brake free stroke without changing lever reach or rider ergonomics.

A deformable pedal bracket lifts the accelerator during a crash to absorb impact force, reduce foot injury, and prevent pedal breakage.

A magnetic rocker and sliding link return an interface to neutral while resisting vibration, saving space, and limiting magnetic disruption.

Dual snap-fit fixing in different directions keeps the pedal angle-detection magnet stable, preventing detachment and wobble.

Time-based braking and rotational torque adjustment smooths haptic feedback changes by rotation direction and speed, reducing operator discomfort.

A threaded piston-rod adjustment lets riders tune brake free stroke without changing lever reach, improving control and setup stability.

Telescopic steering, base plate, and pedal adjustment opens more boarding space in a forklift cab without increasing cab width.

By moving the spring return into the base member, this stylus rotation ring cuts outer diameter while preserving bidirectional detection and click feel.

Dual friction surfaces and spring loading create pedal hysteresis proportional to depression, improving driver feel and ETC position sensing.

A center-of-gravity grip and separate safety switches cut rotational force, support varied mobile terminals, and ease long robot operation.

Shifting the sealing plane from the pedals to the pedal mount improves cabin sound and heat insulation while simplifying fit and assembly.

A rotating shift control hides or exposes the selector and uses lighting cues so drivers can recognize ignition status and transmission mode.

A telescoping brake linkage lets passenger-side instructors apply braking over the center console without costly dual-control installation.

A segmented magnetic output resolves periodic field ambiguity in contactless pedal sensing while keeping magnets small and braking signals precise.

Spring-based pedal resistance and dual position sensors recreate pneumatic brake feel in electric brake systems while adding backup reliability.

A pyrotechnic actuator deforms retainer brackets so the pedal arm moves rearward in a crash, reducing leg impact while preserving post-collision control.

Cooling airflow is mixed with engine exhaust inside the prime mover room to improve heat discharge, noise control, and machine layout.

A retractable pedal pad with a hysteresis module hides during autonomous driving to prevent mal-operation while preserving manual pedal feel.

A flexible seal bends and collapses around a rotary push shaft to block contaminants, preserve waterproofing, and hide internal parts.

Sequential brake-first pop-up and accelerator-first retraction reduce pedal mal-operation risk and improve gear-shift comfort.
