Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the same pressing force is applied to all target parts, then the device structure is simple, but the massage effectiveness varies due to different skin physical characteristics
Solution Approach 1:
The patent applies local quality by assigning different spring constants to different vibrators based on their respective target parts. Each spring constant is specifically designed to match the skin stress characteristics of its corresponding target part, ensuring that each area receives the appropriate pressing force for effective massage.
Solution Approach 2:
The patent changes the parameter of spring constant across different vibrators to adapt to varying skin characteristics. By adjusting the spring constant parameter for each vibrator based on measured skin stress at different target parts, the system achieves consistent massage effectiveness across diverse skin types and locations.
2Reliability
If the spring constants are adjusted to match skin stress of different target parts, then the massage effectiveness is improved, but the device complexity increases
Solution Approach 1:
The patent implements local quality by customizing the spring constant for each vibrator according to the specific skin stress characteristics of its target part. This localized adaptation ensures that each vibrator delivers the precise pressing force needed for effective massage at its designated location.
Solution Approach 2:
The patent modifies the spring constant parameter for each vibrator based on empirical skin stress measurements at different target parts. This parameter adjustment optimizes massage effectiveness while maintaining a relatively simple overall device structure through systematic parameter selection.
3Adaptability or versatility
If multiple vibrators with different spring constants are used, then the pressing forces are optimized for different skin areas, but the manufacturing precision requirements increase
Solution Approach 1:
The patent applies local quality by matching each vibrator's spring constant to the specific skin stress characteristics of its target part. This localized optimization enables the device to adapt to different skin areas while maintaining manageable manufacturing precision through systematic spring constant selection based on measured skin properties.
Solution Approach 2:
The patent adjusts the spring constant parameter for each vibrator based on skin stress measurements, creating a systematic approach to parameter selection that balances adaptability across different skin areas with practical manufacturing precision requirements.
