Understructures TRIZ Cases
- Vehicle-Body Structure With a Center Frame for Distortion Stiffness
A raised center frame links the dash and connection panels to form a closed section, improving distortion stiffness without a large weight increase.
- Vehicle Structure With Closed-Loop Mechanical Fastening
Replacing welds, a joint member links the A-pillar, side sill, and front cross member into a closed loop to preserve rigidity and durability.
- Asymmetric Vehicle Frame Beads for High-Voltage Component Protection
Asymmetric rail beads limit frontal-impact deformation, keeping high-voltage components clear of nearby parts and preserving electrical integrity.
- Roll-Formed Vehicle Crossmember for Side-Impact Battery Protection
A roll-formed hollow beam distributes side-impact forces across the vehicle floor, limiting battery-compartment intrusion and preserving storage volume.
- Hybrid Car Body Structure for Steel-to-Light-Metal Connections
See how a steel structure connects cast light-metal beams to a steel crossmember, distributing side-impact loads away from electric energy stores.
- Vehicle Rear Fascia Assembly With Cam-Guided Flexing for Impact Deflection
Cam surfaces guide side protrusions as a secondary fascia member flexes into place, supporting impact energy deflection and improved rear appearance.
- Vehicle Front Structure With Protruding Joint for Small-Overlap Release
A protruding joint redistributes small-overlap collision loads through the framework and suspension member to release the vehicle efficiently.
- Motor Vehicle Longitudinal Beam Reinforcement for Side Impact
Upper and lower partitions, brackets, and a stiffener absorb side-impact energy while helping protect the vehicle floor and battery assembly.
- Vehicle-Body Structure With Raised Center Frame for Heat and Impact Protection
See how a raised center frame and instrument panel shield a vehicle control device from direct sunlight while absorbing impact loads.
- Vehicle-Body Lower Structure with Protrusion-Based Side Sill Load Transfer
An internally attached side-sill reinforcement and main-body protrusion transmit rearward collision loads without added mass or cost.
- Vehicle Lower-Body Side Sill Reinforcement for Small-Overlap Collision
Diagonal inner and outer reinforcements help the side sill resist front-end crushing and create a widthwise reaction force in small-overlap collisions.
- Compactible Vehicle With Telescoping Supports for Small-Space Storage
Rotatable axles, retractable support legs, and sliding sides let this compactible vehicle expand for use and contract for storage in tight spaces.
- Vehicle Rocker Assembly With Integrated Multi-Cell Reinforcement
Integrated bulkheads form multiple rocker chambers to resist side-impact intrusion while preserving battery tray space and reducing welding needs.
- Resin Cone-and-Bridge Side Sill Reinforcement for Battery Protection
Arrayed resin cones and bridges absorb and redirect side-impact energy inside the side sill to protect the vehicle battery.
- Spring-Loaded Body Tie-Downs for Flexible Chassis Coupling
A spring assembly creates a semi-resilient body-to-chassis joint that permits independent movement and keeps components from becoming loose during detachment.
- Rear Vehicle Body Structure for Battery-Constrained Subframe Mounting
Large batteries can limit subframe mounting space; distributed fastening through the rear side frame and floor panel improves support rigidity.
- Vehicle Side-Sill Shock Absorption Structure With Reinforced Corrugations
Corrugated side-sill members resist ridge-line collapse during oblique side impacts, preserving axial crush energy absorption.
- Vehicle Body Rear Structure for Spare Tire Rear-Impact Control
Rear-impact loading bends a localized floor-pan section to lift the spare tire forward, limiting movement toward the passenger compartment.
- Cast Vehicle Structural Assembly With Non-Circular Energy Pockets
Non-circular pockets integrated into a cast vehicle body address uneven energy absorption and excess weight while supporting component mounting.
- Corrugated Rocker Insert to Reduce Inboard Intrusion
Learn how lateral corrugations stiffen a vehicle rocker insert, redirect side impacts, and reduce battery-tray intrusion.
- Vehicle Cradle Third Load Path for Frontal Impact Stability
Tie rods connect rear cradle extensions to front side rails, distributing impact forces and limiting cradle deformation in hybrid and electric vehicles.
- Lower Vehicle-Body Structure With Tunnel Reinforcement for Seat Protection
Side-collision loads are dispersed through seat brackets, a floor cross member, and tunnel reinforcements to limit floor-panel deformation.
- Lower Vehicle-Body Structure With Asymmetric Rigidity for Collision Buckling
A closed-section frame stiffens the compression-side area to trigger buckling, absorb impact, and preserve cabin space.
- Shell-Type Front Pillar Structure for Compact Crash Load Paths
A shell-type front pillar uses a diagonal carrier and curved side-sill region to route crash loads within a short vehicle front end.
- Polygonal Vehicle Accessory Support Elements for Easier Attachment
A polygonal support element adds flat attachment faces while preserving uniform wall thickness and reducing packing dead-space.
