Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless earphones are stored in a charging box, then the earphones are protected and charged, but users must manually take them out for voice calls which is inconvenient
Solution Approach 1:
The charging box is equipped with sound emitting hole and sound receiving hole that enable it to perform voice call functions independently. The earphones automatically serve the user through the charging box's built-in acoustic channels without requiring manual removal, making the system self-sufficient for voice calls.
2Ease of manufacture
If the charging box has fixed sound path structure, then manufacturing is simple, but the sound path distance cannot be adjusted for optimal audio quality
Solution Approach 1:
The charging box incorporates a telescoping mechanism with sliding first and second casings that enable dynamic adjustment of the sound path distance. The casings can slide relative to each other along a sliding direction, allowing the distance between sound emitting hole and sound receiving hole to be adjusted while maintaining structural integrity and sealing through the telescoping design.
