Leaf Springs TRIZ Cases
- Flat Spiral Spring Tensioner With Wind-Up Limiting for Stable Belt Load
A wind-up limiting section and friction-tuned flat spiral spring maintain belt tension under large loads while damping vibration and slack.
- Folded Composite Single-Leaf Spring Eyes for Delamination Resistance
Folded spring eyes with stitched composite plies improve stress resistance and cut leaf spring weight versus steel.
- Anisotropic Lattice Structure With Sarrus Hinges for Vibration Damping
Bendable solid hinges in lattice ribs convert impact energy into axial motion, improving shock absorption and vibration isolation across frequencies.
- Dual-Mass Vibration Absorber With Single-Bolt Mass Pair Assembly
A single through-bolt secures paired masses across a support plate, cutting parts and cost while enabling resonance frequency tuning.
- Austenitic Stainless Steel for Plate Spring Settling Resistance
Controlled martensite-austenite structure improves plate spring settling resistance while preserving high strength, ductility, and accuracy.
- Buckling Beam Isolation via Adjustable Boundary Conditions
Changing the beam end restraint through elastomeric clamping enables tunable negative stiffness for stable low-frequency vibration and shock isolation.
- Double-Mass Vibration Absorber With Single-Bolt Frequency Tuning
A single bolt secures paired masses through one carrier plate, cutting assembly cost while enabling resonant frequency adjustment and reliable fixation.
- Ribbon Aluminum Alloy Composition for Lightweight Conductive Springs
A ribbon aluminum alloy balances low weight with 40% IACS conductivity, 350 MPa strength, and fatigue life for conductive and spring components.
- Lattice Structure With Solid Hinges for Energy Absorption
Solid hinge portions form Sarrus linkages in lattice ribs, enabling axial compliance, shock protection, and broad-frequency vibration damping.
- Rubber Bearing Half-Shell Locking Structure for Noise Reduction
Form-fitting projections and recesses lock rubber bearing half-shells to curb movement noise while keeping assembly simple and secure.
- Buckling Beam Isolation with Adjustable End Restraints
Adjustable beam end restraints continuously tune negative stiffness, improving low-frequency vibration isolation and shock absorption over large displacements.
- Leaf Spring Package Geometry for Vibration Welding Load Distribution
Curved, variable-thickness leaf springs improve stress distribution in vibration welding spring packages, extending lifespan with fewer springs.
- Wind Turbine Tower Damper With Passage Opening for Vibration Control
A pendulum damper in damping liquid suppresses tower vibrations while preserving a safe passageway for wind turbine service personnel.
- Wind Turbine Tower Damper With Central Passageway Access
A pendulum and damping-liquid layout suppresses vortex-induced tower vibration while preserving safe service access inside the wind turbine tower.
- Interlocking Rubber Bush Half Shells for Noise Reduction
Interlocking projections and depressions stop half-shell movement in a rubber bush, cutting noise while simplifying alignment and assembly.
- Buckled Beam Isolation with Variable Negative Stiffness
A buckled beam with adjustable boundary stiffness maintains near-constant negative stiffness over large displacements for vibration and shock isolation.
- Prosthetic Foot Spring Assembly With Speed-Dependent Stiffness
A carbon fiber spring with non-Newtonian polyurethane shifts damping and energy return with gait speed, improving prosthetic foot stability.
