Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional electronic musical instruments use standard interfaces, then compatibility is maintained, but creative expression and interaction capability are limited
Solution Approach 1:
The instrument interface is segmented into multiple independent sensor zones (touch sensors and proximity sensors) that can detect different user interactions separately. Each sensor type handles specific interaction modes, allowing complex creative expression through combination of simple, manageable sensor inputs rather than requiring a single complex interface system
Solution Approach 2:
A controller serves as an intermediary between the physical sensors and the digital audio workstation, translating touch and proximity sensor signals into MIDI-compatible control signals. This intermediary layer enables compatibility with standard MIDI systems while supporting advanced interaction capabilities through the sensor network
2Ease of operation
If touch and proximity sensors are integrated, then interaction control is enhanced, but device complexity increases
Solution Approach 1:
The controller is designed with multi-functionality, serving as both a signal processor for touch/proximity sensors and a MIDI interface for digital audio workstation communication. This universal component handles multiple functions (sensor signal processing, MIDI translation, and instrument control) that would otherwise require separate systems, reducing overall device complexity while maintaining enhanced interaction control
Solution Approach 2:
Traditional mechanical interfaces (physical keys, buttons, and switches) are replaced with electronic touch sensors and proximity sensors that detect user input through electrical and optical fields. This substitution eliminates mechanical wear and complexity while providing more nuanced interaction control through digital sensing of touch and proximity states
3Adaptability or versatility
If multiple sensor types are used, then musical expression control is improved, but manufacturing complexity increases
Solution Approach 1:
Touch sensors and proximity sensors are merged into a unified sensor array integrated on the instrument body, rather than being separate assemblies. This merging approach allows both sensor types to be manufactured and calibrated together as a single unit, reducing assembly complexity while maintaining the ability to detect multiple interaction modes for enhanced musical expression control
