Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a dedicated high-power regulator is used to power high-power PAs for emergency transmissions, then the power supply capability is improved, but the area requirements and device complexity increase
Solution Approach 1:
The patent applies universality by enabling existing power supplies (designed for cellular PAs) to serve dual purposes: powering both cellular communication PAs and high-power emergency PAs. The power management module dynamically routes power from these existing supplies to different PAs based on operational mode, eliminating the need for a dedicated high-power regulator and reducing overall device area.
2Power
If a dedicated high-power regulator is used to power high-power PAs, then the power supply capability is improved, but the device complexity increases
Solution Approach 1:
The power management module is designed to universally control power distribution to multiple types of PAs (cellular and emergency) using the same power supply infrastructure, reducing device complexity by eliminating dedicated hardware for emergency power while maintaining full power supply capability through software-controlled power routing.
3Use of energy by moving object
If multiple power supplies are used to concurrently power high-power PAs, then the power consumption is reduced, but the device complexity increases
Solution Approach 1:
The patent merges multiple existing power supplies (originally intended for cellular PAs) to collectively power the high-power emergency PA. The power management module combines the output of these power supplies and dynamically allocates power among different PAs, achieving reduced power consumption through efficient utilization of existing supplies while managing complexity through centralized control logic.
Solution Approach 2:
The power management module serves as a universal controller that handles power distribution for both cellular and emergency PAs, enabling the same power supply infrastructure to support multiple functions simultaneously. This universal approach reduces the need for separate dedicated power management circuits, thereby reducing overall device complexity while enabling efficient power consumption.
