Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple lines with different Ishare functions are provided for different power configurations, then power transmission accuracy is improved, but device complexity and layout space increase
Solution Approach 1:
The patent applies universality by designing a single line that can handle multiple power configurations through dynamic configuration. Instead of providing separate lines for different power scenarios, the system uses one versatile line that adapts to various Ishare functions based on the selected power configuration, thereby reducing device complexity while maintaining measurement precision.
Solution Approach 2:
The patent implements dynamics by making the line configuration adaptable and changeable based on different power scenarios. The system dynamically selects and configures the appropriate Ishare function for the chosen power configuration, allowing the line to serve different purposes without physical reconfiguration, thus simplifying the overall device structure.
2Reliability
If PSU is selected according to instantaneous maximum overclocking power, then power reliability is improved, but cost increases due to over-provisioning
Solution Approach 1:
The patent applies dynamics by enabling the PSU to operate flexibly across different power configurations. Instead of being locked into a fixed high-power configuration, the system dynamically adjusts the power delivery based on actual needs, allowing the PSU to be sized more appropriately while maintaining reliability through configurable power levels.
Solution Approach 2:
The patent implements parameter changes by allowing the power configuration parameters to be adjusted based on actual system needs. The system can change power delivery parameters dynamically, selecting appropriate power levels for different operating scenarios, thereby avoiding the cost waste of always provisioning for maximum overclocking power while maintaining reliability when needed.
3Adaptability or versatility
If multiple lines are provided for different Ishare functions, then adaptability to different configurations is improved, but layout space and device complexity increase
Solution Approach 1:
The patent applies universality by creating a single adaptable line that can serve multiple configuration purposes. Instead of dedicating separate physical lines to different Ishare functions, the system designs one universal line that can be configured for different power scenarios, thereby maintaining configuration adaptability while significantly reducing the layout space required.
4Measurement precision
If current detection circuit amplifies output current signal by preset multiple, then power transmission accuracy is improved, but device complexity increases
Solution Approach 1:
The patent implements parameter changes by using a preset multiple for signal amplification that can be optimized for different scenarios. Instead of complex variable amplification circuits, the system uses fixed amplification factors that are predetermined and optimized, achieving accurate power transmission measurement while keeping the circuit design relatively simple and manageable.
