Silencing Apparatus TRIZ Cases
- Integrally Molded Porous Partition Muffler for Noise Reduction
A muffler uses integrally molded porous partitions to create sub-cavities for acoustic fiber placement.
- Reconfigurable Engine Air Intake and Exhaust System
Modular stage packages resolve platform inflexibility by enabling easy component substitution for varied power configurations.
- Muffler Internally Supported Tuner Straight Pipe
Segmented end cap zones with angled flanges hold a straight perforated pipe, preserving length for sound absorption while reducing packaging volume.
- Vehicle Muffler Dual Exhaust Pipe Noise Reduction
Segmented chambers with localized acoustic absorbents increase discharge pipe length to eliminate booming noise while preventing heat transfer to the car body.
- Exhaust Scavenging System With Central Flow Enhancement
Central exhaust passage extends through collector outlet plane to maintain consistent cross-sectional area and enhance flow velocity.
- Hybrid Locking Cable Tie for Low Insertion Force and High Tensile Strength
A hybrid locking cable tie uses offset wedges to engage strap teeth on opposite sides, balancing insertion force with loop tensile strength.
- Compact Inline Inlet with Integrated Cast Ring for Exhaust Systems
A compact inline inlet uses an integrated cast ring to provide structural mounting support within exhaust gas aftertreatment assemblies.
- Hexagonal Muffler with Curved Veins for Back Pressure Reduction
Curved internal veins accelerate exhaust gases through a venturi effect, reducing back pressure while maintaining noise suppression.
- Rear Muffler Assembly with Shutoff Flap for Noise Control
A rear muffler assembly uses a shutoff flap to direct exhaust gases through perforated pipes and insulating material.
- Dual Outlet Muffler with Intermediate Pipe for Noise Reduction
A vehicle muffler uses an intermediate pipe to fluid connect multiple chambers formed by baffles, routing exhaust gas through distinct paths.
- Exhaust Pipe Surface Coat Layer Thickness Uniformity
A surface coat layer uses distinct inorganic material compositions to maintain uniform thickness on exhaust pipe bumps and edges.
- Muffler Resonance Chambers for Low-Frequency Noise Reduction
Segmented closed spaces function as resonance chambers to reduce low-frequency noise while maintaining a compact double-pipe structure.
- Vehicle Exhaust Noise Reduction via Helmholtz Resonator Chamber
A vehicle exhaust system uses a branch pipe with punched resonance holes inside a divided muffler housing to attenuate sound waves.
- Diffusion Alloyed Exhaust Component with High Chromium Weld Beads
High chromium filler metal in the weld bead isolates the primary substrate from salt and urea, resolving corrosion at joints.
- Vehicle Exhaust Resonance Chamber Integration
A flexible connection line links an exhaust pipe to a resonance chamber within the vehicle body structure.
- Double-Pipe Muffler Multi-Frequency Acoustic Design
Segmented inner pipe openings create distinct acoustic paths that resolve the trade-off between multi-frequency attenuation and installation space constraints.
- Work Vehicle Exhaust Pipe Segmentation for Cooling
Segmented exhaust outlets expand boundary surface area to cool engine gases while minimizing increases in exhaust back pressure.
- T-Shaped Baffle Silencer Layout for Exhaust Vibration
A T-shaped baffle plate divides a silencer into three expansion chambers, resolving insufficient gas expansion and partition wall vibration in compact layouts.
- Muffler Retaining Wall Force Closure for Exhaust Pipe
Pre-formed detent formations enable elastic pipe insertion, eliminating complex reshaping operations during assembly.
- Exhaust Muffler Double Tube Noise Reduction
Nested inner and outer communicating tubes prevent direct gas flow between ports, ensuring full expansion within chambers to resolve volume utilization limits.
