Flutes/Fifes TRIZ Cases
- Piccolo Conical Body Tone Hole Scheme for Low C Intonation
A redesigned conical piccolo uses a specific tone hole scheme to resolve intonation deterioration in the third octave, ensuring even tone down to low c.
- Flute Thumb Rest Stability Without Sound Degradation
A flute thumb rest mounted on the mouthpiece provides stable support for the player's right hand.
- Piccolo Redesign Conical Cylindrical Bore Intonation
Segmented bore design resolves tonehole size restrictions, enabling lower register notes.
- Acute-Angled Headpiece for Symmetrical Transverse Flute Posture
A two-leg head joint arranged at an acute angle allows straight posture while maintaining optimal sound quality and distribution.
- Piccolo Interchangeable Adapter Socket for Cross-Manufacturer Compatibility
An interchangeable adapter socket bridges incompatible tube dimensions between different manufacturers, resolving pitch adjustment constraints.
- Symmetric Flute Mouthpiece for Straight and Curved Headjoints
A symmetric mouthpiece design enables interchangeable straight and curved flute headjoints using a single universal component.
- Refractory Metal Flute Headjoint Mechanical Assembly
Mechanical expansion joins refractory metal flute headjoint components without soldering, preserving tube hardness and enabling precise CNC manufacturing.
- Angled Flute Head Joint Redistributes Weight Force
An angled flute head joint redistributes the weight force vector into vertical and horizontal components, reducing arm and back strain during playing.
- Wind Instrument Footjoint and Bore Design for Intonation
A wind instrument footjoint with a normally closed low B key and tapered bore sections.
- Wind Instrument Head Joint With Reed And Blow Hole
Integrating a reed part with a blow hole in one head joint expands the musical range downward without adding mechanical complexity.
- Flute Curved Tube Reduces Mouthpiece-Keys Interval
A flute employs a curved tube between the mouthpiece and body tubes to reduce the interval for smaller players without compromising axis alignment.
- Flute Headjoint Tuning Plug with Concave Surface and Open Crown
A flute headjoint tuning plug features a three-dimensional concave surface to amplify sound waves within the sonic chamber.
- Flute Head Joint Stopper Seal with O-Ring
Replacing moisture-sensitive cork, this mechanical plug uses an O-ring to maintain an airtight seal and prevent air leaks in the flute head joint.
- Conical Piccolo C# Trill Key Mechanism
An improved conical piccolo trill key mechanism resolves difficult third octave G/A fingering by adding a dedicated tone hole opening for accurate intonation.
- Flute Wind Guard Clamshell Hinge for Ambient Airflow Control
Segmented arcuate cover with torsion-biased clamshell hinge blocks ambient air currents while maintaining embouchure access.
- Pad Ring Retainer for Woodwind Tonehole Sealing
A pad ring retainer supports pad material and membrane, eliminating air leakage from tonehole misalignment.
- Continuous Pitch Slide Flute With Sealing Rod
A slide flute uses a sliding rod to seal a pipe slot, resolving sluggish movement and air leakage issues.
