Percussion Musical Instruments TRIZ Cases
- Drum Tuning System with Cord and Brackets for Uniform Tension
A drum tuning system uses a cord and brackets to distribute tension uniformly across the drum head.
- Bass Drum Pedal Spring Nesting and Trigger Extraction
A bass drum pedal uses a nested compression spring and column-mounted trigger for precise beat detection.
- Resilient Membrane Support Structure for Vibration Isolation
A resilient membrane support structure decouples resonating devices from rigid surfaces to enable omnidirectional micro-movement.
- Non-Contact Sound Absorber for Musical Instruments
An air gap separates sound-absorbing materials from musical instruments, reducing volume up to 88% while preserving resonance.
- Drum Mounting Device With Memory Lock Mechanism
A drum mounting device uses a memory lock and bracket to enable quick height adjustments.
- Stave Drum Dovetail Joints Eliminate Glue Dampening
Dovetail joints join staves without glue, eliminating adhesive dampening and enhancing drum resonance.
- Leg Muscle Strengthening Device with Deformable Relief Portions
Resiliently deformable relief portions on a leg strengthening device generate reaction forces that prevent horizontal slipping and maintain stability.
