Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple controls are provided for adjusting content properties, then the ability to complicatedly change properties improves, but the ease of operation deteriorates because it is difficult to accurately operate multiple controls at high speed
Solution Approach 1:
The patent combines multiple control functions into a single control unit. Instead of requiring separate controls for each parameter (cut-off frequency, resonance level, localization), one control unit can simultaneously adjust multiple parameters by assigning different parameter sets to different operational modes or time periods, enabling complicated property changes without requiring multiple physical controls
Solution Approach 2:
The control unit is designed with multi-functionality to perform various control tasks. By programmatically assigning different parameter groups to a single control unit, the system achieves universal control capability across multiple content properties, allowing one control to replace multiple specialized controls while maintaining operational simplicity
2Adaptability or versatility
If multiple controls are provided for adjusting content properties, then the ability to complicatedly change properties improves, but the productivity deteriorates because it is difficult to accurately operate multiple controls at high speed
Solution Approach 1:
The patent merges multiple control operations into a single control unit that can programmatically adjust multiple parameters simultaneously. This combination enables high-speed property changes without requiring sequential manual adjustment of multiple controls, thereby maintaining productivity while achieving complicated control objectives
Solution Approach 2:
The system performs preliminary programming of parameter assignments before actual control operations. By pre-configuring which parameters should be adjusted together and in what sequence, the system prepares control routines in advance, enabling rapid execution during performance without requiring real-time complex decision-making by the operator
3Adaptability or versatility
If time-series data is used to complicatedly change parameters, then the adaptability improves, but the ease of operation deteriorates because it is not suitable for real-time performance or ad-lib scenarios
Solution Approach 1:
The patent implements dynamic parameter control where the control unit can switch between different parameter sets based on real-time conditions or performance context. Instead of relying on fixed time-series data, the system dynamically adjusts parameters during performance, enabling both complicated control capabilities and real-time adaptability for ad-lib scenarios
Solution Approach 2:
The system incorporates feedback mechanisms that allow the control unit to respond to real-time performance conditions. By monitoring performance state and adjusting parameters accordingly, the system achieves adaptability without requiring pre-programmed time-series data, making it suitable for interactive real-time performance and improvisational scenarios
