Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a Rumble interface is used to input and output vibration intensity signals, then the vibration intensity can be controlled, but the vibration frequency cannot be adjusted
Solution Approach 1:
The patent introduces a vibration signal conversion system as an intermediary between the application layer and the vibration execution layer. This conversion system receives vibration signal data from applications, converts it according to preset protocols, and generates processed vibration signal data that can be executed by vibration units. This intermediary layer enables frequency adjustment capability without requiring fundamental changes to the existing Rumble interface, thus resolving the contradiction between adaptability and device complexity.
Solution Approach 2:
The patent implements parameter changes by converting vibration signal data according to different preset protocols that correspond to different vibration units. Each protocol defines specific parameter mappings between the original vibration intensity signals and the target vibration frequency/intensity combinations. This allows the system to adjust vibration frequency by changing the conversion parameters rather than changing the fundamental signal acquisition and execution mechanisms.
2Adaptability or versatility
If vibration signal data is converted according to preset protocols, then different vibration frequencies can be achieved, but the processing complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-defining multiple preset protocols before actual vibration signal conversion occurs. Each preset protocol contains pre-configured conversion rules and parameter mappings for different vibration units and scenarios. When an application needs vibration output, the system simply selects the appropriate preset protocol rather than creating conversion rules in real-time. This significantly reduces the processing complexity during execution while maintaining the ability to support multiple vibration modes.
Solution Approach 2:
The patent implements universality by designing a unified vibration signal conversion system that can handle multiple types of vibration units (e.g., different types of vibration motors) through a single framework. The system uses a common signal acquisition interface, a centralized conversion module with multiple preset protocols, and a universal signal generation output. This multi-functional design allows the same system to support various vibration modes and units without requiring separate processing paths for each type.
3Adaptability or versatility
If original vibration signal data is acquired from applications, then the vibration intensity can be controlled, but the vibration frequency remains fixed
Solution Approach 1:
The patent maintains ease of operation for applications by keeping the original Rumble interface unchanged for signal acquisition. The complexity of frequency adjustment is isolated in the intermediary conversion system. Applications continue to use the simple intensity-based Rumble interface, while the conversion system handles the frequency transformation in the background. This ensures that applications do not need to be modified or become more complex, while still achieving frequency adjustment capability.
