Conical Piccolo Trill Key Mechanism for G/A Trills
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conical piccolos require difficult and awkward fingering to produce an accurate and in-tune trill between the notes of G and A in the third octave, as existing mechanisms like the C sharp trill key and G-A trill key do not effectively facilitate this trill, limiting their usability in orchestral performances.
Innovation Solution
An improved conical piccolo design incorporating an additional tone hole opening with a trill key mechanism that allows for easy production of the third octave G/A trill, utilizing an axle with an external tubing cover, a trill key pad, and a spring catch system to apply rotational forces, enabling simultaneous venting of tone holes for clear and responsive trilling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the standard cylindrical flute fingering is used on a conical piccolo, then the G/A trill can be played easily, but the fingering does not work on the conical piccolo due to acoustic differences
Solution Approach 1:
The patent modifies the conical piccolo's acoustic parameters by adding a C sharp trill key mechanism that changes the venting configuration. This allows the instrument to accommodate the standard cylindrical flute fingering pattern while producing the correct acoustic result for the G/A trill on a conical bore, effectively bridging the gap between the two different acoustic systems.
Solution Approach 2:
The C sharp trill key acts as an intermediary mechanism between the standard flute fingering and the conical piccolo's acoustic requirements. It provides an additional tone hole opening that mediates the interaction between the player's finger configuration and the instrument's acoustic system, enabling the trill to work on the conical bore while maintaining the familiar flute fingering pattern.
2Ease of operation
If the C sharp trill key is added to the conical piccolo, then five of six main trills can be played easily, but the third octave G/A trill still requires awkward fingering
Solution Approach 1:
The patent enhances the C sharp trill key mechanism to serve multiple functions: it enables the G/A trill while also maintaining capability for other trills. By integrating the additional tone hole opening with the existing key mechanism, the system achieves universal applicability across different trill types, making the conical piccolo as versatile as the cylindrical flute in terms of trill execution.
3Reliability
If the G-A trill key is used on the conical piccolo, then the third octave G/A trill can be produced, but it is unresponsive and can only be played at the loudest volumes
Solution Approach 1:
The patent employs a pneumatic system through the addition of a C sharp trill key that opens an extra tone hole, creating a pressure differential that responds sensitively to the player's breath control. This pneumatic mechanism provides responsive G/A trill production across the full dynamic range, eliminating the limitation of the previous G-A trill key that only worked at loud volumes.
4Adaptability or versatility
If multiple fingerings are listed for the G/A trill, then more options are provided, but all of them are difficult to implement requiring simultaneous finger movements
Solution Approach 1:
The patent extracts the complex simultaneous finger movement requirement from the fingering options by introducing a mechanical key mechanism. The C sharp trill key handles the complex coordination of multiple finger movements automatically, allowing the player to simply depress the key rather than coordinating multiple fingers simultaneously. This extraction of complexity from the manual process greatly simplifies the ease of operation.
