Controlling Members TRIZ Cases

Coaxial first and second control rods remove handle interference, keep grip distances consistent, and improve mower operation.

Force sensing, multiple springs, and auto-calibration give a joystick variable hold and smoother feedback without large electromagnetic coils.

A single-entry light guide uses distributed exit surfaces to evenly illuminate a console slide slit with lower construction complexity.

A locking mechanism lets one pedal switch between single-axis and multi-axis operation, reducing switch variants and user mode errors.

A prestressed torsion spring and movable stop give pilots clear limit feedback without blocking lever motion, improving awareness in low-visibility use.

Swappable joystick rings change range of motion and trigger a mechanical switch so the controller can adjust sensitivity and speed settings.

A cam preloads the vehicle control lever in neutral to suppress play, reduce vibration, and keep ergonomic multi-axis operation compact.

Electrical current drives a core-attractor gap change to create compact haptic feedback while saving space and battery life in electronic devices.

A shiftable spring zero point and self-locking adjustment reduce stick-slip and preserve steerability in wheel loader hand controls.

Preloaded bearing bodies and eccentric stop surfaces keep the grinding gap stiff yet adjustable, improving particle size consistency under fluctuating flow.

Separate finger controls for throttle and rotation improve pilot grip security, reduce accidental inputs, and increase navigation precision.

A shoe-shaped platform, pedal holder, heel plate, and adjustable strap stabilize the rider's foot while attaching securely to an existing exercise bike pedal.

A bistable bending element lets shape memory wires switch positions without return springs, cutting wire stress, energy use, and space.

Master and lane nodes wirelessly guide autonomous vehicles through newly created lanes, avoiding manual intervention and route disruption.

A U-shaped guard shields exposed backhoe pedals from dropped tools while preserving rear operator access and preventing unintended hydraulic actuation.

An input multiplier and offset button actuation reduce handlebar cable clutter, avoid series-link failures, and improve shifting precision.

A pluggable adjusting interface lets installed lamps tune brightness, timing, and energy-saving settings without replacing the lamp.

A cylindrical cam and gear-driven slider retract the central selector knob in less space while improving reliability and axial force handling.

A spring-biased locking pivot lets the crank handle fold for compact storage while holding a strong, stable operating position.

A pre-stressed torsion spring creates an overridable stop on the pilot lever, delivering clear tactile limit feedback with a simple mechanism.

A one-piece removable rudder pedal module integrates adjustment and braking functions to cut parts, weight, and maintenance time.

A single aircraft PSU knob combines reading light, gasper control, and a visible notification ring to reduce panel clutter and improve crew-passenger communication.

A non-sequential switch pattern lets a rotary encoder encode more knob positions in the same diameter, reducing size, weight, and cost.

Segmented base, sensor, and keycap interfaces cut tolerance buildup in soft pressure-sensor buttons while simplifying failure diagnosis and part replacement.

A detachable wireless switch with its own power supply simplifies bicycle handlebar controls while preserving hydraulic lever function.

Accelerometer-based pedal and shoe sensing gives cyclists instant heel-angle feedback to maintain efficient pedaling during extended outdoor rides.
