Load-Supporting Pillars TRIZ Cases

Folding and stamping create a sunshade operating beam with variable height, consistent width, higher stiffness, and less material waste.

Folding and stamping create a variable-height sunshade operating beam that keeps width controlled, improves mid-span stiffness, and reduces waste.

A three-step flange forming sequence spreads deformation at steel plate corners, avoiding notches while preserving rigidity and sealing.

A preformed step supports one strip edge during transverse rolling, enabling selective thickening without deforming the strip body.

Hot stretch forming and linear friction welding create curved reinforced structural components with lower residual stress, less machining, and stronger bonds.

Cold-formed flanges and hydroforming create closed-section vehicle body parts with more shape freedom, lower cost, and shorter cycle time.

Fluid-expanded sheet metal chambers create an axial support member that carries high loads while reducing structural mass and occupied volume.

Raised shoulder and flat-base end portions increase truss member contact area to resist snapping and deformation under stress.

A single pre-coated steel sheet is cold-formed into a lighter beam with stamped web apertures and clinched joints to speed manufacture and installation.

A two-stage molding sequence compresses a preformed flange and web shape to suppress giga steel springback and improve shape holdability.

A cambered open-web beam-joist with chord angles and a central plate cuts floor construction cost and installation complexity while preserving strength.

Plastic forming turns sheet metal into a one-piece platform lift rail with an integrated rack flange, cutting joining steps and improving curved-rail stability.

Sequential wall bending, stretching, and bend-back change hat-section height while preventing cracks at boundary portions.

Individually movable clamping rollers stay perpendicular to the central flange, preventing bending stress in variable hat beam forming.

A roll-formed intermediate profile is later split into multiple end products, cutting cycle time while maintaining profile accuracy and lower roller loading.

Pre-bent intermediate stock suppresses wall width displacement during press forming, widening pad projection tolerance while keeping vertical walls precise.

Flat and bending roll forming create variable-thickness crossmembers with precise geometry and uniform properties without machining.

A cambered open-web joist with triangular sections, angle beams, and a top plate simplifies fabrication while preserving structural strength.

A cambered open-web beam-joist uses triangular webs, chord angles, and a top plate to simplify manufacture while preserving strength and utility access.

Planar roll forming creates local thickness profiles before bending, producing precise vehicle cross members with less machining and shorter production time.

By thinning the fold-over area during roll profiling, doubling areas contact directly to raise buckling resistance and cut guide rail cost.

Sequential flange folding distributes corner deformation in automotive reinforcements, preventing breakage while preserving connection rigidity.

A staged pad-and-punch forming sequence cuts cracking in shape-changing ridges and warping in vertical walls of high-strength steel press parts.

Individually displaced clamping rollers stay perpendicular to the central flange, preventing bending stress in variable hat beam forming.

Hot-stamped L-shaped inner and outer parts replace a weak welded sill-pillar junction, improving crash resistance and passenger compartment protection.

Pre-attached reinforcement blanks are hot stamped with inner pillars to simplify handling, standardize blanks, and preserve roof crush strength.

Inward-bent sheet metal folds are high-frequency welded to create a double-walled support profile with smooth surfaces and stronger joints.

Pre-attached reinforcement blanks are hot stamped with pillar parts to ease handling, support multiple vehicle models, and resist roof crush.

Injection molding plastic around a hollow tube forms an integral angle-type air tool housing.

Segmenting the pillar into offset panels with variable thickness eliminates material duplication, reducing weight while maintaining connection stability.

Segmenting the door into polymer and metal modules reduces weight while avoiding molding complexity and bonding strength issues.

A B-pillar central beam uses two distinct soft zones to manage mechanical behavior and reduce component weight.

Interior walls segment the hollow extruded header beam, isolating attachment notches from continuous load paths to maintain structural integrity.
