Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional volume adjustment methods are used in terminal devices, then volume control is simple, but volume adjustment efficiency is low and power consumption increases
Solution Approach 1:
The patent applies parameter changes by analyzing amplitude characteristics of sound sources and adjusting volume based on different sound types (music, noise, speech). The system dynamically changes volume parameters according to detected sound characteristics, achieving efficient volume adjustment while reducing unnecessary power consumption compared to traditional uniform volume control methods
Solution Approach 2:
The terminal device performs self-service by automatically detecting sound source types and adjusting volume without user intervention. The device analyzes amplitude information of playing content, determines sound categories, and autonomously applies appropriate volume adjustments, eliminating the need for manual volume control while optimizing power usage
2Productivity
If traditional volume adjustment methods are used in terminal devices, then operation is simple, but volume adjustment efficiency is low
Solution Approach 1:
The system implements self-service functionality by automatically detecting sound source types through amplitude analysis and applying appropriate volume adjustments without requiring user operation. This maintains ease of operation (users don't need to manually adjust volume) while dramatically improving volume adjustment efficiency through intelligent sound-based differentiation
Solution Approach 2:
The patent changes volume parameters dynamically based on detected sound characteristics. By analyzing amplitude information and identifying different sound types (music, noise, speech), the system automatically applies optimized volume adjustments, improving efficiency without complicating user interaction
3Adaptability or versatility
If uniform volume adjustment is applied to all sound sources, then operation is simple, but desirable sound content cannot be amplified and noise cannot be suppressed
Solution Approach 1:
The patent applies local quality by treating different sound sources differently based on their characteristics. Instead of uniform volume adjustment, the system analyzes amplitude information of each sound source, identifies its type (music, noise, speech), and applies customized volume adjustments tailored to each sound's needs, enhancing adaptability while maintaining manageable system complexity
Solution Approach 2:
The system changes volume parameters selectively based on sound source type. By detecting amplitude characteristics and categorizing sounds, the patent applies different volume adjustment strategies for different sound types, achieving superior sound quality optimization without excessive system complexity
