Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If additional circuitry is added to enable power output capability, then the device can output power, but the cost and power consumption increase
Solution Approach 1:
The patent applies multi-functionality by enabling the power management IC to operate in both power receiving mode and power output mode using the same core circuitry. The bidirectional converter and buck-boost converter share common components and control logic, allowing a single device to perform both charging and wireless power transmission functions without requiring separate dedicated circuits for each mode.
Solution Approach 2:
The patent merges the power receiving and power output functions into a single integrated power management system. The bidirectional converter combines rectification and inversion functions, while the buck-boost converter integrates voltage regulation and power conversion in one circuit block, eliminating the need for separate circuitry and reducing overall power consumption.

Solution Approach 1:
The power management IC is designed with universal functionality to handle both power receiving and power output operations. By implementing bidirectional converters and buck-boost converters that can operate in multiple modes, the device eliminates the need for separate dedicated circuits, thereby reducing component count, manufacturing complexity, and overall cost.
Solution Approach 2:
The patent combines multiple power management functions into integrated circuit blocks that serve dual purposes. The bidirectional converter merges rectification and inversion capabilities, while the buck-boost converter integrates voltage regulation and power conversion, reducing the total number of components needed and lowering manufacturing costs.
3Use of energy by moving object
If bidirectional converter and buck-boost converter are used for both power receiving and outputting, then power consumption is reduced, but device complexity increases
Solution Approach 1:
The patent employs universal bidirectional and buck-boost converters that can seamlessly switch between power receiving and power output modes. These multi-functional converters are controlled by a single control circuit that manages both operating modes, reducing the need for separate control logic and simplifying the overall system architecture despite the enhanced functionality.

AI summary
A transceiver includes a bidirectional converter, a buck-boost converter and a voltage regulator. The bidirectional converter receives downstream power and converts the downstream power into a rectified voltage. The buck-boost converter converts the rectified voltage into a buck voltage by decreasing a voltage level of the rectified voltage and the voltage regulator converts the buck voltage into a regulated voltage by reducing fluctuations in the buck voltage. In the event that the transceiver outputs upstream power, control circuitry can repurpose the voltage regulator to convert a system voltage into a load voltage by reducing fluctuations in the system voltage, repurpose the buck-boost converter to convert the load voltage into a boost voltage by increasing a voltage level of the load voltage, and repurpose the bidirectional converter to output the boost voltage in the form of upstream power.
