Percussion Musical Instruments TRIZ Cases

A sprung striker assembly integrates a spring mechanism with an adjustable head to strike mounted idiophones seamlessly.

A drumhead tuning rim uses a tensioning cable routed through grooved bearing wheels to secure the membrane.

Modular interactive panels connect via universal joiners to form reconfigurable sound environments that reduce storage volume while maintaining engagement.

A drum retaining apparatus uses a strap member to connect the bass drum rim directly to the drummer's seat for secure positioning.

Integrated damping strips resolve installation difficulties of felt strips by providing adjustable vibration absorption within the drumhead structure.

A mutable tambourine jingle assembly uses a flexible frame to mute unwanted sounds.

A drumhead tuning rim system uses a cable tension dial assembly to adjust pitch across the membrane surface.

A pedal mechanism uses a sliding mobile member and chain to rotate the drumstick shaft for angle changes.

Polygonal drum support feet use acoustic reflecting materials to maintain sound isolation from underlying surfaces.

A portable drum kit container houses a bass drum within an acoustic chamber to propagate resonant sound waves through baffles.

A drum tuning apparatus combines a striking mallet head with an elongated lug engagement member on a single shaft for precise instrument adjustments.

Segmented pipe units and nested joints reduce transport volume while maintaining structural stability for electronic drums.

Removing the pad body from the impact transmission path allows gentle strikes to activate rigid dummy snare wires, resolving quietness versus sound reliability.

Segmented weights on the inner shell suppress high-order harmonics, resolving bass drum weight issues while enhancing low-tone clarity.

Segmented attachment via insertion parts and hook parts eliminates hoop recesses, reducing instrument size.

Variable porting systems adjust low-frequency back pressure ratios to resolve adaptability versus complexity trade-offs in percussion instruments.

Nested clutch and detent splines lock upper cymbals to a tubular adjuster, resolving the trade-off between reliable axial positioning and structural complexity.

Pre-cut drum slips wrap around shells with hardware openings, eliminating disassembly and drying time required by paint refinishing.

Interlocking body components in a built-up drum eliminate complex locking mechanisms, resolving portability issues caused by heavy integral drums.
