Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If personalized HRTF is used as a fixed value, then calculation efficiency is improved, but user adjustability of sound field and sound quality deteriorates
Solution Approach 1:
The patent transforms the static, fixed personalized HRTF into a dynamic, adjustable parameter. The adjustment unit allows users to modify the personalized HRTF in real-time, enabling dynamic control over sound field and sound quality while maintaining the efficiency benefits of personalization.
Solution Approach 2:
The patent enables users to change parameters of the personalized HRTF through the adjustment unit. By allowing modification of HRTF parameters, the system maintains calculation efficiency while providing adaptability for different sound field and sound quality preferences.
2Device complexity
If personalized HRTF is used as a fixed value, then system complexity is reduced, but sound quality customization capability deteriorates
Solution Approach 1:
The adjustment unit serves as an intermediary between the fixed personalized HRTF and the user's sound quality requirements. It provides a simple interface for customization without requiring complex system changes, thus maintaining low system complexity while enabling sound quality customization.
3Adaptability or versatility
If adjustable personalized HRTF is implemented, then user control over sound field and sound quality is improved, but device complexity increases
Solution Approach 1:
The patent extracts the adjustment functionality as a separate, modular adjustment unit. This isolation allows the core HRTF system to remain simple while providing advanced customization capabilities through the dedicated adjustment module, minimizing overall system complexity.
