Understructures TRIZ Cases

A ductile main piece bonded to a brittle UHSS patch forms a hybrid structural member for vehicle frameworks.

A measurement pipe with a low thermal expansion coefficient houses an ultrasonic sensor to detect fuel levels via wave reflection time.

Low strength frame portions bend inward during small overlap collisions to contact the powertrain, preventing forward movement and fuel pipe detachment.

A shield redirects external collision forces along a controlled load path through the frame rail to protect mounting brackets.

Segmented truss stiffening element reduces subframe weight while maintaining structural rigidity and improving engine compartment accessibility.

An expandable shell filled with bulk material stabilizes hollow profile cavities through thermal expansion.

Relocating a modified K-member and trailing arms below the lowered floor resolves the conflict between wheelchair accessibility and available floor area.

Transverse and longitudinal concave beads in die-cast side members manage energy absorption and prevent barrier intrusion into the cabin.

Segmented patch components with convex strips reinforce the floor bottom panel between seats, resolving rigidity trade-offs against structural complexity.

A double stretch trailer uses slideable front and rear extensions to adjust length dynamically.

A motor vehicle floor reinforcing system uses a deformable absorption zone and rigid reinforcing zone to manage impact forces.

Conductive filler pipe outer layer grounds metallic components, eliminating complex cable routing and reducing manufacturing costs.

Pivoting load beams redirect impact forces laterally across the vehicle frame, reducing concentrated intrusions and energy transfer to the occupant cabin.

Dynamic excitation current pulses heat the switching valve to prevent ice formation, ensuring reliable ventilation without unintentional opening.

Segmented propeller shafts contract axially to displace engines rearward, resolving collision cushioning needs without increasing production costs.

Segmenting the front end structure at the bulkhead reduces assembly complexity while maintaining structural integrity through independent pre-assembly.

A circular B-pillar unit uses a double bonding structure with carbon fiber layers to replace welding connections.

Segmented planar walls form a Z-shaped cross-section to reduce vehicle sill mass without compromising longitudinal impact resistance.

An adjustable axle with pivot arms changes trailer deck height, eliminating steep inclines during heavy object loading.

A front vehicle body reinforcing structure disperses collision loads through segmented members coupled to the wheel housing panel and front pillar.

Trough-shaped cross-members lower the midsection height of a lowboy trailer bogie, allowing boom arms to pass without interference.

A fuel tank vent uses a non-circular opening to smoothly discharge air and vapor during refueling.
