Innovation Solution
A reed musical instrument equipped with an airflow device, internal sensors, processing device, storage device, and output device that allows customizable musical sound production by synthesizing airflow information with reed data and customization information, enabling features like reed combination customization, automatic tuning, and adjustable audio characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional reed musical instruments are used, then the instrument structure is simple and easy to manufacture, but the instrument cannot play in multiple scales while maintaining just-intonation tuning
Solution Approach 1:
The instrument is divided into separate modules: a conventional harmonium body for acoustic sound production and a digital processing unit for electronic sound synthesis and tuning control. This segmentation allows each module to optimize its function independently while working together to achieve multi-scale playability with just-intonation tuning.
Solution Approach 2:
The digital processing unit serves multiple functions: it processes airflow from the conventional harmonium, synthesizes electronic sounds, enables custom tuning for different scales and keys, and provides both acoustic and electronic output modes. This multi-functionality resolves the contradiction by embedding versatility within a unified system.
2Adaptability or versatility
If traditional reed musical instruments are used, then the instrument is simple in design, but it cannot be tuned according to a vocalist's requirements
Solution Approach 1:
The instrument features dynamic tuning capabilities where the digital processing unit can adjust tuning parameters in real-time based on the vocalist's requirements. The system can adapt to different keys, scales, and tuning systems dynamically during performance, transforming a static instrument into a dynamically adjustable one.
Solution Approach 2:
The system incorporates feedback mechanisms where sensors detect airflow characteristics and this information is fed back to the digital processing unit, which then adjusts tuning parameters accordingly. This feedback loop enables precise tuning customization without requiring complex manual adjustment mechanisms.
3Adaptability or versatility
If traditional reed musical instruments are used, then the instrument maintains conventional form factor, but it is not playable in every pitch
Solution Approach 1:
The digital processing unit acts as an intermediary between the conventional harmonium's fixed pitch reeds and the desired variable pitch output. It receives acoustic signals from the harmonium and synthesizes electronic sounds at any desired pitch, effectively mediating between the limitations of the acoustic component and the requirements for extensive pitch coverage.
Solution Approach 2:
The system replaces the mechanical pitch adjustment mechanism with an electronic synthesis approach. Instead of physically adjusting reed positions or using multiple instruments, the digital processing unit generates electronic sounds that can be precisely controlled at any pitch, substituting mechanical complexity with electronic precision.
