Percussion Musical Instruments TRIZ Cases

Pivoting anchoring devices attach to kick drum spurs and feature pointed bases that engage floor coverings, resolving shifting caused by rocking motion.

Sliding member adjusts leg angle to secure bass drum pad against angular momentum displacement.

Welded screwing lugs on a thermoplastic drum shell preserve structural continuity for sound wave transmission while simplifying assembly.

A pliable one-piece holder conforms to drumsticks, reducing stress on anatomy and equipment.

Motorized inserting mechanism repositions percussion instruments horizontally via pedal control, resolving spatial constraints to double available drum beats.

A portable drum kit consolidates snare, bass, and cymbal components into a single frame structure for compact musical performance.

An adjustable sand belt structure resolves the trade-off between improved acoustic realism and increased mechanical complexity in practice drums.

Tuning partials to f and 3f/2 creates a perceived f/2 strike tone, reducing bell mass eightfold without lowering physical dimensions.

An integrated cymbal mounting assembly uses a centering clip to prevent rod contact and a friction nut to lock rocking motion settings.

A drum shell with non-contact vibration damping portions preserves tone color by suppressing high-frequency components through an air layer.

An integrally molded drumhead eliminates swaging or adhesive fixation steps, reducing manufacturing complexity while enhancing fixation strength.

Automated hydraulic stamping replaces manual hammering to resolve production time versus quality consistency contradictions in steel drum manufacturing.

Vertical stacking of resonance bodies within a compact box maintains ideal sound characteristics while reducing horizontal dimensions.

A hybrid percussion instrument merges a box drum with an internal djembe to produce deeper bass tones while retaining the portable cajon form factor.

A snare drum strainer uses a self-lubricating bearing and shaft sleeve to enable fluid mechanical movement of the brake part.

Tool-free thumbscrew adjustment enables rapid damping scenario selection without accessing internal structure.

An automated tuner uses microprocessor-controlled stepper motors to apply precise torque, eliminating manual adjustment time.

A drum pedal tension spring pivots on a lower bracket surface to minimize friction and stabilize the mechanism.

A steel drum distributes 37 note areas across a concave surface and an extended skirt to produce wider musical range.

Integrated magnets in the mount and handle secure the snare throw-off position, eliminating accidental disengagement from weak torsion springs.

A portable drum kit system consolidates bass cajon components and a convertible storage container into a single transport unit.

A body-supportable musical instrument carrier uses a J-rod assembly with compound bends to secure drums while expanding leg room.

Curved alignment pieces on the tensioning band ensure uniform snare wire contact, resolving misalignment issues without manual adjustment mechanisms.

A drum counterhoop clamping device uses a sliding chute and locking member to adjust plate distance for secure instrument attachment.

An adjustable stop separates the dampening pillow from the resonant head, allowing simultaneous dry and resonant sound production without external microphoning.

A flamenco cajon features a tuneable membrane element mounted on its side panel to produce distinct acoustic vibrations.

A portable timpani gauge uses a magnetic drum clip and string indicator for precise pitch marking.

A bass drum cradle secures the instrument via brackets engaging front and rear lugs to distribute weight across the support structure.

An open resonator chamber holds liquid that deforms under vibration to reveal cymatic patterns while refracting sound waves from tonal elements.

A snare muffler uses a slotted bracket and flexible banding to slide a felt pad along the drum axis for dynamic tone control.

A compact drum kit merges snare, bass, and tom components into a single hollow housing unit.

Clamps secure an elastic cord between the hoop and head, enabling easy repositioning without damaging the drumhead.

Segmented engaging ridges on the stopper prevent unwanted rotation, resolving sensor misalignment and cable connectivity issues during dynamic striking.

Pivoting post folds to reduce height while latch locks position.

A pedal structure uses a locking element to clamp a rotating block against an upright post.

Segmented compartments enable simultaneous shaker and drum performance, resolving the contradiction between acoustic versatility and structural complexity.

Adjustable shafts separate opposing drum heads to resolve limited pitch range in fixed drums.

A rigid snare drum end plate clip uses a quick-change strap system to maintain balanced pressure on wires.

A drum pedal switching device repositions the coil spring between use and storage states.
