Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If related art methods are used to correct compatibility problems, then compatibility is improved, but side effects are introduced
Solution Approach 1:
The patent performs preliminary detection of the driving voltage path connection status during the initialization phase before any data operations commence. By identifying the memory device version early and configuring the appropriate voltage path in advance, the system avoids compatibility issues during operation without requiring complex correction methods that may introduce side effects.
Solution Approach 2:
The patent introduces an intermediary detection mechanism that identifies the memory device version through voltage path detection. This intermediary step allows the system to bridge compatibility gaps between different UFS versions by selecting the appropriate configuration, avoiding the need for complex correction methods that could introduce side effects.
2Adaptability or versatility
If hardware architecture is redesigned to support multiple UFS versions, then compatibility is improved, but design complexity and material costs increase
Solution Approach 1:
The patent segments the driving voltage supply into multiple independent paths, each configured for different UFS versions. By providing separate voltage paths that can be selectively activated based on detection results, the design avoids the complexity of creating a fully integrated multi-version support architecture while maintaining compatibility across versions.
Solution Approach 2:
The patent creates a universal host hardware architecture that can support multiple UFS versions through a single detection and selection mechanism. Rather than designing separate hardware architectures for each version, the universal design uses voltage path detection to accommodate different versions, reducing overall design complexity and material costs.
3Reliability
If version-specific hardware designs are implemented, then operational reliability for that version is improved, but adaptability to other versions deteriorates
Solution Approach 1:
The patent implements dynamic adaptation by detecting the memory device version and switching to the appropriate voltage path configuration. This dynamic behavior allows the system to maintain high operational reliability for the detected version while simultaneously maintaining adaptability to other versions through the detection and selection mechanism.

AI summary
A method for performing device type detection of a memory device with aid of driving voltage path detection and associated apparatus are provided, where the memory device is installed on a printed circuit board (PCB) of host device. The method includes: in response to a detection signal obtained from a driving voltage terminal of a set of driving voltage terminals among two sets of driving voltage terminals within the PCB, determining a device type of the memory device, for determining whether a memory device version of the memory device belongs to a first set of versions or a second set of versions; and selecting a voltage level corresponding to the device type from multiple predetermined voltage levels to be a selected voltage level, for providing the memory device with the selected voltage level via at least one portion of driving voltage terminals among the two sets of driving voltage terminals.
