Solution Approach 1:

The patent implements dynamic voltage control by switching between different voltage sources (first voltage source for high-speed operation, second voltage source for low-power operation) based on operational requirements. The voltage selector dynamically chooses the appropriate voltage level, enabling the system to adapt its power consumption to the current data transmission needs, thus resolving the contradiction between maintaining high speed and reducing power consumption.

Inventive Principle:

Solution Approach 2:

The patent changes the voltage parameter dynamically by providing multiple voltage sources with different voltage levels and selectively switching between them. This allows the system to adjust its operating voltage according to the data transmission requirements, achieving high-speed transmission when necessary and low-power operation when possible, thereby resolving the contradiction between speed and power consumption.

Solution Approach 1:

The patent implements a voltage selector that serves multiple functions: it selects between different voltage sources, controls the power supply to various circuits, and enables the system to operate in different modes (high-speed and low-power). This multi-functional component reduces overall device complexity by consolidating voltage management tasks into a single universal controller, thus resolving the contradiction between circuit performance and device complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent merges the voltage selection and distribution functionality into a single integrated voltage selector component that manages multiple voltage sources and supplies them to different circuits. This consolidation simplifies the voltage management architecture, reducing the number of separate control mechanisms needed and thereby resolving the contradiction between achieving optimal circuit performance through multiple voltage sources and maintaining manageable device complexity.

Inventive Principle:
Principle #5Merging (Combining)
