Gaming Console Power Control for Wireless Controller Charging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Gaming machines with wireless controllers face challenges in powering the controllers without wasteful power consumption, as they require the gaming machine body to remain turned on for battery charging, leading to unnecessary energy usage even after charging is complete.
Innovation Solution
An electronic apparatus connected to a device via a cable that detects when the battery is fully charged and automatically turns off power supply to prevent wasteful energy consumption, allowing the gaming machine body to charge the controller without needing to remain on.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the gaming machine body remains turned on to charge the controller battery, then the battery can be charged, but power is wasted continuously
Solution Approach 1:
The gaming machine body incorporates a detection function that monitors the charging status of the controller battery. When the battery is fully charged, the system automatically detects this state and turns off the power supply, creating a closed-loop feedback mechanism that eliminates continuous power waste while ensuring reliable charging.
Solution Approach 2:
The system enables automatic power management where the gaming machine body autonomously controls its own power state based on battery charging status. The detection and power control functions work together to make the system self-regulating, turning off power automatically when charging is complete without requiring user intervention.
2Loss of energy
If the gaming machine body is turned off, then power consumption is reduced, but the controller cannot be charged
Solution Approach 1:
The system uses real-time detection of battery charging status to control power state transitions. The feedback mechanism ensures the machine body remains on only when necessary for charging, and automatically transitions to off state when charging is complete, resolving the contradiction between power savings and charging capability.
3Adaptability or versatility
If USB bus-powered operation is used to charge the controller, then wireless controller operation is enabled, but the gaming machine must stay on
Solution Approach 1:
The system implements automatic detection of USB cable connection and battery charging status. When a controller is connected via USB for charging, the system detects this state and maintains power supply only for the duration needed. Once charging is complete, the system automatically turns off, enabling wireless controller versatility without continuous power waste.
Solution Approach 2:
The system prepares for wireless controller operation by enabling USB bus-powered charging capability in advance. This preliminary configuration allows the controller to be charged and ready for wireless use, while the automatic power control ensures energy is consumed only when necessary for this preparatory charging action.

AI summary
Reduction of wasteful power consumption is envisaged. A power supply function-equipped electronic apparatus (10) is configured to be capable of supplying power to a battery device (20) incorporating a battery (21) by use of a cable (30) connecting the apparatus (10) with the device (20). A detection section (13) detects whether charging of the battery (21) incorporated in the battery device (20) is complete through the cable (30). When charging of the battery (21) is detected to be complete, a power control section (12) turns off power of the power supply function-equipped electronic apparatus (10). This invention can be applied illustratively to gaming machines and the like each composed of a gaming machine body and its controller.
