Unified Power Interface for Electronic Device Testing and Charging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices require separate connections and components for power management during production testing and battery charging, leading to redundant wiring and increased complexity.
Innovation Solution
An electronic device with a connecting unit that can connect to either a first power managing unit for driving the device or a second power managing unit for charging, using a common wiring and switching module to select the appropriate power source based on the connected external power supply device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate power circuits are used for production testing and battery charging, then both functions can be performed independently, but the device complexity increases and redundant components are required
Solution Approach 1:
The patent merges the production test power circuit and battery charging power circuit into a single integrated power management system. The power management IC consolidates both power paths, allowing the same physical connection to serve dual purposes: powering the device during production testing and charging the battery during normal operation. This eliminates redundant power circuits while maintaining independent functional capability through software-controlled power routing.
Solution Approach 2:
The power management system is designed with universal functionality to handle both production testing and battery charging through a single connection interface. The power management IC can dynamically switch between test mode and charging mode based on external signals, making the power circuit multi-functional. This universal design eliminates the need for separate dedicated circuits for each function.
2Adaptability or versatility
If separate connection pins are used for power circuit and charging circuit, then both can be connected simultaneously, but the connecting unit complexity increases
Solution Approach 1:
The patent combines separate connection pins for power and charging into a single shared connection pin. The same physical pin serves both as the power input during production testing and as the charging input during normal operation. The power management IC internally distinguishes between test power and charging power based on control signals, eliminating the need for separate physical connection pins while maintaining full adaptability.
3Reliability
If separate external power supply devices are connected for production test and charging, then both functions can operate independently, but the component redundancy increases
Solution Approach 1:
The patent merges the power supply interfaces for production testing and battery charging into a single unified interface. The same physical connection and power management circuitry handle both test power input and charging power input. The system uses software control and signal detection to distinguish between test mode and charging mode, eliminating redundant power supply components while maintaining independent operational capability for both functions.

AI summary
An electronic device and an operation method thereof are provided. The electronic device includes a connecting unit configured to connect to an external power supply device that provides power to the electronic device; a first power managing unit configured to drive the electronic device using power provided from a first external power supply device connected to the connecting unit; a second power managing unit configured to charge a battery contained in the electronic device using power provided from a second external power supply device connected to the connecting unit; and a switching module configured to connect the connecting unit to one of the first power managing unit and the second power managing unit. Also, connection pins are not configured redundantly and respectively for external power supply devices, but a connecting unit is unified through a single common wiring and is commonly used, and thus, a wiring and components for supplying power may be reduced.
