Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual music editing and software programming are performed to adapt to different music, then the control precision and effect quality are improved, but the device complexity and operation difficulty increase significantly
Solution Approach 1:
The control circuit automatically analyzes music signals and generates corresponding control signals without requiring manual programming or editing. The system serves itself by autonomously adapting to different music characteristics, eliminating the need for user intervention in complex programming tasks while maintaining high effect quality
Solution Approach 2:
The patent replaces manual mechanical programming operations with automated electronic signal processing. The control circuit uses electronic analysis and generation of control signals based on music signal characteristics, substituting the mechanical process of manual editing and programming with an automated electronic system
2Manufacturing precision
If manual music editing and software programming are performed to adapt to different music, then the effect quality is improved, but the ease of operation deteriorates
Solution Approach 1:
The control circuit autonomously performs music analysis and control signal generation without requiring user programming skills. The system self-adjusts to different music characteristics, allowing users to simply connect audio equipment without undergoing complex programming processes
Solution Approach 2:
The control circuit acts as an intermediary between the music signal and the controlled device. It automatically translates music characteristics into appropriate control signals, eliminating the need for users to manually program the relationship between music and device responses
3Manufacturing precision
If professional assistance is required for device setting and programming, then the effect quality is improved, but the ease of operation and accessibility to common users deteriorates
Solution Approach 1:
The control circuit automatically adapts to different music types and characteristics without requiring professional programming knowledge. Common users can simply connect their audio equipment and the system will autonomously generate appropriate control signals based on the music being played
Solution Approach 2:
The patent replaces the mechanical process of professional programming and configuration with automated electronic music signal analysis. The control circuit electronically processes music signals and automatically generates control signals, eliminating the need for professional human intervention
4Measurement precision
If fixed programming is used for specific music, then the control precision is improved, but the adaptability to different music deteriorates
Solution Approach 1:
The control circuit dynamically adjusts its control signals based on real-time analysis of music characteristics. Rather than using fixed programming, the system continuously adapts to different music types, tempos, and patterns, maintaining precise control while achieving versatility across different music genres
Solution Approach 2:
The control circuit changes its control parameters based on the analyzed music signal characteristics. It automatically adjusts control signal frequency, amplitude, and timing according to the specific music being played, enabling both precision for the current music and adaptability to future music changes
