Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a tongue sensor and breath sensor are added to detect tonguing and breath pressure, then the instrument's ability to replicate nuanced musical expressions is improved, but the device complexity increases
Solution Approach 1:
The electronic wind instrument integrates multiple sensing functions (tongue sensor for tonguing detection, breath sensor for breath pressure measurement) into a single device, allowing it to replicate various musical expressions and control parameters simultaneously. This multi-functionality enables the instrument to handle diverse playing techniques without requiring separate devices for each function.
Solution Approach 2:
The processor acts as an intermediary that receives signals from the tongue sensor and breath sensor, processes these inputs, and translates them into appropriate control commands for the sound generation and output systems. This intermediary processing layer integrates the sensor data and coordinates the complex control requirements.
2Adaptability or versatility
If dynamic control of sound volume based on tonguing time and breath pressure is implemented, then the musical expressiveness is improved, but the control system complexity increases
Solution Approach 1:
The system dynamically adjusts sound volume and other parameters in real-time based on the detected tonguing time and breath pressure. The control parameters are not fixed but continuously adapt to the player's actions, enabling nuanced musical expressions. The processor continuously monitors sensor inputs and modifies output parameters accordingly.
Solution Approach 2:
The system uses feedback from the tongue sensor and breath sensor to continuously adjust the sound output. The detected tonguing time and breath pressure values are fed back to the processor, which then modifies the sound generation parameters to match the player's intentions, creating a closed-loop control system.
3Ease of operation
If multiple sensors and processing functions are integrated, then the instrument's control capability over sound volume is improved, but the manufacturing complexity increases
Solution Approach 1:
The patent combines multiple sensing and processing functions into a single integrated electronic wind instrument. The tongue sensor, breath sensor, processor, and sound generation components are merged into one device, allowing the instrument to control sound volume and other parameters through unified hardware and software integration.
