Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If two externally provided power supplies with different voltages are used to power the storage card, then the storage card can operate with required voltage levels, but the compatibility with other storage card slots becomes difficult to achieve
Solution Approach 1:
The patent applies parameter changes by incorporating voltage conversion circuits that can dynamically adjust and convert between different voltage levels (3.3V, 1.8V, 1.2V). This allows the storage apparatus to adapt its power consumption parameters to match different host device requirements, resolving the contradiction between maintaining reliable power supply and achieving broad compatibility
Solution Approach 2:
The storage apparatus achieves universality by designing a power management system that can accept a single external power supply and internally generate multiple voltage levels needed for different operating modes and components. This multi-functional power system enables the same storage card to operate reliably across different host devices with varying power requirements
2Reliability
If dedicated card slots are designed for specific storage cards with dual power supply requirements, then power supply stability is ensured, but the ease of operation and compatibility with other storage card slots deteriorates
Solution Approach 1:
The voltage conversion circuits enable parameter changes by transforming a single external voltage into multiple internal voltage levels, allowing the storage apparatus to maintain reliable power supply for all components while being compatible with standard single-power-supply card slots, thus improving ease of operation without sacrificing reliability
