Noise Insulation Doors/Windows TRIZ Cases
- Hatch for capsule unit
See how an inward-opening plate hatch resolves the capsule unit contradiction between sound ins
- Vehicle Door Leaf Structure With Gas Gaps for Sound Insulation
Gas-filled intermediate spaces break vibration bridges in a vehicle door leaf, improving sound insulation without adding much mass or losing strength.
- Hollow Core Door Structure for Better Acoustic Isolation
Thicker facings, a hollow air cavity, and absorptive inserts raise hollow core door STC while avoiding solid core weight and cost.
- SCIF Door Threshold Assembly for Precise RF Seal Alignment
Pre-assembled jacking blocks and a seal retainer cover hold the threshold in place, cutting SCIF and RF door installation time.
- Fiberglass Interior Door Structure for Wood-Like Acoustics
Foam, spacers, and recessed fiberglass skins create a shaker-style interior door that preserves wood-like appearance while improving sound and heat insulation.
- Resonator-Stacked Glazing for Low-Frequency Acoustic Insulation
Stacked resonators of different lengths in a glazing cavity absorb low-frequency sound without adding bulk or requiring custom tuning.
- Window Acoustic Damping Device for Ventilation Noise Control
An acoustic damping system uses passive silencers and active noise cancellation to reduce outside noise by 35 dB while maintaining ventilation airflow.
- Sliding Window Roller Guide Preventing Vertical Reaction Force
A sliding window roller guide separates vertical lifting from horizontal movement to ensure smooth operation of heavy aluminum alloy sashes.
- Multi-glazed Window Noise Reduction Device with Hooked Membrane
A multi-glazed window noise reduction device uses a vibrating membrane secured by edge hooking members to maintain homogeneous tension.
- Sliding Window Cover Members with Rollers for Draft Sealing
Roller-equipped cover members seal horizontal sliding windows, blocking drafts and rain while maintaining stable frame engagement.
- Aluminium Door Framework with Active Acoustic Noise Cancellation
Modular aluminium profiles with pneumatic sealing and multipoint locking eliminate visible fasteners, enabling motorized operation of heavy doors.
- Sound Insulation Door Glazing Bead Inversion
Inverting the glazing bead perpendicular to the glass plane eliminates bending stress on fasteners, allowing thinner frames and maximizing clear surface area.
- Window Sound Dampening Members for Noise Reduction
Segmented rubber and foam members reduce wind noise without increasing device complexity.
- Glass Door Sealing with Overlapping Protrusions
A glass door apparatus uses overlapping protrusions and cavities in functional end caps to create a secure mechanical seal between door leaves.
- Elastomeric Coating for Hollow Metal Door Performance
Elastomeric coating on hollow door panels reduces heat transmission and sound while maintaining clean aesthetics.
