Steering Columns TRIZ Cases

An automatically-stowed steering column replaces complex airbags with an explosive retractor that moves the shaft away from occupants during impact.

A hollow shaft motor drives a threaded spindle nut to adjust steering column position.

An articulated quadrilateral seat mount slides along an oblique steering column to resolve ergonomic adaptability conflicts while absorbing road irregularities.

Nested bracket leaves maintain consistent clamping force despite restricted space constraints.

Reinforcing member redirects torsional forces through clamp brackets to the vehicle frame, reducing stress on the slit edge.

A cam surface moves a lever to rotate a pawl away from an inner jacket, reducing handle rotation force while preventing sliding during collisions.

A plastic beam blocking element anchors in lateral recesses to constrain actuator movement until impact forces exceed a predetermined threshold.

A self-locking telescope actuator uses a clutch mechanism to enable axial translation and rotational motion within steering column assemblies.

A sliding member reduces friction between movable and fixed brackets, stabilizing the energy-absorbing load during impact.

A resilient ring-shaped member constrains the male steering shaft within the female spline to prevent axial escape during assembly.

Deformation strips absorb crash energy through plastic deformation within a compact steering column assembly.

A steering apparatus uses a guide groove in the outer column to route an electrifying lead, reducing space requirements.

Outer column slit enables inner column release during secondary collisions to absorb impact energy.

Merging the crash element into the holding part wall surface absorbs kinetic energy through deformation without increasing radial installation space.

A steering device load absorbing mechanism uses a low friction sliding member to control resistance during secondary collisions.

Segmented tubes and an energy absorption plate reduce material waste and burrs while maintaining rigidity through hydroformed components.

A jacket connector with pre-determined shear resistance interconnects steering column jackets to permit telescopic movement.

A steering column support system uses a deformable lower wall to rotate the wheel away from the driver.

A lateral stabilizer biases the steering column to prevent unexpected movement in non-adjustment directions during mode transitions.

Positioning the support point at 1.1 times the pin spacing eliminates extra lugs, reducing axial length while maintaining secure fixation.

A vehicle steering assembly uses a coupler head and raised contact surface to vary clamping force across mounting members.

A steering column locking mechanism uses a resilient body to apply restoring force to the locking member.

Direct coupling of an energy absorption strap to the telescope drive nut eliminates separate brackets, reducing assembly complexity.

Widened side plate parts create a wedge effect against the steering column, improving distance bracket holding force without adding complexity.

A collapsible steering column assembly uses a blocking part to redirect axial loads away from frangible connectors during adjustment.

A separate lifting mechanism actuates form-fitting elements in a vehicle steering column.

Welds a steering column bracket at two close circumferential locations to secure fixation without distorting the press-fitted inner column.

Integrated breakaway link manages peak force spikes while reducing assembly complexity and vibration noise in steering columns.
