Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional audio output systems are used, then the system structure is simple, but the system cannot be adapted for various applications and requires rebuilding when usage changes
Solution Approach 1:
The patent implements a universal audio output system that can handle multiple applications through a standardized parameter information generation process. The system generates parameter information that can be applied across different use cases (audio guides, notifications, communications, etc.) without requiring separate system implementations, thus achieving multi-functionality while maintaining manageable complexity
Solution Approach 2:
The patent changes the approach from rebuilding systems to adjusting parameters. By generating parameter information based on content identification and status identification, the system can adapt to various applications by modifying output parameters (volume, direction, timing) rather than changing the fundamental system structure
2Adaptability or versatility
If conventional audio output systems are used, then the system structure is fixed, but the system cannot dynamically adjust parameters of virtual sound imaging middleware
Solution Approach 1:
The patent introduces dynamic parameter adjustment through a control unit that modifies audio output parameters in real-time based on generated parameter information. The system dynamically adjusts virtual sound image parameters such as output direction, volume, and timing according to content type and user status, transforming a static system into a dynamic one
Solution Approach 2:
The patent implements feedback mechanisms where the system generates parameter information based on content identification and status identification, then uses this feedback to control audio output. The status identification unit monitors user state and provides feedback for adjusting output parameters, creating a closed-loop control system
3Adaptability or versatility
If the system processes multiple use cases, then the application versatility increases, but the parameter control complexity increases
Solution Approach 1:
The patent segments the parameter control process into distinct functional units: content identification information generation, status identification information generation, and parameter information generation. Each unit handles specific aspects of parameter control, reducing overall complexity by dividing the control task into manageable segments that can be independently processed
