Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a simple, low-cost, and easily assembled musical instrument that can be played without requiring extensive skill or dexterity, and which can facilitate group participation in creating a melody.
Innovation Solution
A musical instrument comprising a main body with a hollow chamber and a percussive bar, which can be easily assembled and disassembled. The instrument is tunable to a predetermined pitch by positioning a plug member within the main body, and it includes strap members to retain the main body in the assembled configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the musical instrument is designed to be easily assembled and disassembled, then the ease of manufacture and operation is improved, but the structural stability and tuning precision may deteriorate
Solution Approach 1:
The main body is divided into multiple segments that can be easily assembled and disassembled. Each segment can be independently manufactured and then joined together, simplifying the assembly process while maintaining the overall structural integrity needed for precise tuning.
Solution Approach 2:
The plug member is pre-positioned within the hollow chamber during the assembly process to establish the predetermined pitch. This preliminary positioning ensures that the tuning precision is achieved without requiring complex post-assembly adjustments, resolving the contradiction between easy assembly and tuning precision.
2Adaptability or versatility
If the main body is made configurable between assembled and disassembled configurations, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The main body is segmented into multiple sections that can be connected and disconnected. This segmentation enables the instrument to transition between assembled and disassembled configurations without requiring complex mechanical systems, as each segment is a simple, self-contained unit.
Solution Approach 2:
The plug member is nested within the hollow chamber of the main body, and the percussive bar is positioned within the assembled structure. This nesting arrangement allows the instrument to be compact when assembled and easily disassembled by removing the nested components, providing adaptability without excessive complexity.
3Ease of operation
If the instrument is designed for group participation with predetermined pitches, then the ease of operation is improved, but the measurement precision requirements increase
Solution Approach 1:
The instrument is pre-tuned to a predetermined pitch during the assembly process by positioning the plug member at a specific location within the hollow chamber. This preliminary tuning action ensures that each instrument in the group produces the correct pitch without requiring the player to make precise adjustments, thus maintaining ease of operation while achieving pitch accuracy.
Solution Approach 2:
The instrument is designed to be self-tuning through its configurable main body and plug member positioning system. Once assembled with the plug member in the correct position, the instrument automatically maintains the predetermined pitch without requiring external tuning adjustments by the player, ensuring both ease of operation and pitch precision.

AI summary
A musical instrument, and more particularly, a percussive instrument which can easily be assembled and disassembled, and which is associated with a predetermined pitch. The musical instrument comprises a main body which, when assembled and in use, defines a hollow chamber configured as a sound box. A percussive bar is fixed relative to the main body and spaced therefrom by at least a first spacer member. The main body is characterised in by being configurable in one of an assembled configuration and a disassembled configuration. The musical instrument is further characterised by being tuned to a predetermined pitch during assembly.
