Shoulder Marching Tuba Viewing Region Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Over-the-shoulder marching tubas have a cluster of tubing that obstructs the player's view to the left, limiting their ability to perform maneuvers requiring a clear view to this side, necessitating accommodations in field show compositions.
Innovation Solution
The shoulder marching tuba features an arrangement of airflow tubing that defines a relatively open viewing region by using a series of U-shaped tubes and valve systems, allowing the player to maintain an unobstructed view to the left while playing, with valves positioned to adjust pitch and rings for ergonomic handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the tubing is arranged in a traditional cluster configuration, then the structural integrity and compactness of the tuba are maintained, but the player's view to the left is obstructed
Solution Approach 1:
The tubing is redistributed from a horizontal cluster configuration to a vertical arrangement, utilizing the third dimension (height) to resolve the spatial conflict. The tubing extends downward and wraps around the player's body, creating a clear horizontal viewing zone while maintaining all necessary valve connections through vertical and diagonal routing paths.
Solution Approach 2:
The tubing system is divided into distinct functional segments: a vertical main run, horizontal connection sections to valves, and wrap-around portions. This segmentation allows each section to be optimized for its specific function while collectively providing both structural integrity and unobstructed viewing clearance.
2Ease of operation
If the tubing is redistributed to provide a clear view, then the player's maneuverability is improved, but the structural stability may be compromised
Solution Approach 1:
Different portions of the tubing system are given different structural characteristics. The vertical main run provides rigid structural support, while connection sections use flexible positioning to accommodate player movement. Strategic support points are reinforced to maintain stability during dynamic marching maneuvers.
Solution Approach 2:
The tubing arrangement incorporates dynamic positioning capabilities, allowing the instrument to adapt its configuration during movement. The redistributed tubing can flex and reposition slightly to accommodate various marching positions while maintaining structural integrity through its anchored vertical configuration.
