Bumpers TRIZ Cases
- Collision Sensor Structure for Mobile Robots in Tight Spaces
Dual-stage sensor displacement detection helps a mobile robot sense gentle and strong collisions and escape trapped positions in tight spaces.
- Robot Cleaner Bumper Spring Layout for Multi-Directional Impact Protection
A pretensioned spring-guided bumper lets robot cleaners absorb impacts from multiple directions without separate guiding parts.
- Rubber Expansion Press-Fit Joining for Long Hollow Members
An elastic rubber expander press-fits a hollow member into another part, enabling strong long-member joining without welding heat or complex equipment.
- Multi-Chamber Crash Box Structure for Predictable Bumper Folding
Separated outer and inner chambers guide crash folding and energy transfer, reducing joint failure at the bumper cross member.
- Vehicle Cladding Support Structure for Protected Lightweight Mounting
A cavity-backed support structure mounts sensors or lighting behind vehicle cladding, protecting them while reducing panel weight and complexity.
- Retractable Bumper Assembly for Pedestrian Leg Impact Absorption
A speed-controlled retractable bumper uses a rod, spring, and actuator to absorb pedestrian leg impact energy while preserving ground clearance.
- Reinforced Crossbeam Structure to Prevent Pole-Impact Tearing
Oblong-recess reinforcement inside a vehicle crossbeam helps stop pole-impact tearing and limits obstacle penetration into the cabin.
- Inflatable Crush Can Structure for Adaptive Bumper Energy Absorption
An inflatable metallic crush can uses pyrotechnic inflation and elongation to adapt bumper stiffness and absorb frontal impact energy.
- Vehicle Bumper Reinforcement Bar Forming With Springback Bending
Controlled over-bending and springback form a one-piece bumper reinforcement bar with fewer steps, lower cost, and preserved rigidity.
- Bumper Reinforcement Bar Roll Forming With Overbending Springback
Overbending and elastic springback shape a one-piece bumper reinforcement bar with fewer bending and welding steps while preserving rigidity.
- Vehicle Bumper Crash Box Coupling Without Welding
Mechanical coupling channels replace welded crash box joints, cutting assembly cost while improving load transfer and crash deformation behavior.
- Vehicle Crossmember End Plate Weld Layout for Impact Rotation
A folded end plate with weld beads moved off the front edge cuts impact stress and preserves component rotation in vehicle absorbers.
- Metal Bumper Sensor Mounting Without Separate Retainers
Stamped apertures and tabs in a metal bumper hold the sensor directly, cutting retainer parts, assembly steps, and cost.
- Asymmetric Crossbeam Structure to Prevent Pole-Crash Tearing
Offset dividing walls and a thicker rear flange shift the neutral axis to reduce tensile stress and prevent crossbeam tearing in pole crashes.
- Nested Structural Member Layout to Suppress Crash Cross-Section Collapse
An inner closing member with a restricting portion prevents early wall tilting and cross-sectional collapse, improving crash load resistance.
- Corrugated Vehicle Energy Absorber for Compact Impact Protection
A corrugated core joined to a plastic structure absorbs impact energy with lower weight and bulk while protecting vehicle elements from deformation.
