Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If sound and vibration signals are uniformly pushed to the driving module independently, then each unit can produce acoustic effects, but the correlation effect between sound and vibration intensity is poor
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting the power ratio parameter 'a' based on different system modes (e.g., audio mode, vibration mode, balanced mode). This allows the sound and vibration signals to be reweighted according to the current operational requirements, establishing a matching relationship between their intensities while maintaining flexible signal processing architecture.
Solution Approach 2:
The patent implements dynamics by making the power ratio parameter adaptive rather than fixed. The system automatically adjusts the weighting between sound and vibration signals based on real-time system mode detection, enabling dynamic correlation control that responds to different usage scenarios without requiring complex manual configuration.
2Ease of operation
If different sound and vibration intensities are not generated according to scenarios, then the system structure remains simple, but user experience is affected due to lack of scenario-based adaptation
Solution Approach 1:
The patent applies self-service by having the system automatically detect the current system mode and configure the appropriate power ratio without user intervention. The system serves itself by autonomously adjusting sound and vibration intensity based on predefined modes (audio, vibration, balanced), eliminating the need for manual configuration while enhancing user experience through scenario-based adaptation.
Solution Approach 2:
The patent implements preliminary action by pre-configuring multiple system modes with their corresponding optimal power ratios before actual operation. When a mode is selected, the system already has the appropriate weighting parameters ready, allowing immediate scenario-based adaptation without requiring real-time complex calculations or user configuration.
