Solution Overview
Problem
Users of multiple hand-held electronic devices and accessory devices, such as video game controllers, face challenges with frequent battery replacement and the fragility of charging connectors, which can lead to operational issues and increased costs.
Innovation Solution
A charging system with a base that provides physical support and DC power to video game controllers via mini-USB connectors, including a current detector and indicator for charging status, and an AC-to-DC converter to convert externally supplied power, along with a power adapter capable of charging multiple devices simultaneously through USB and FireWire ports.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate power adapters are used to charge multiple devices, then each device can be charged independently, but the complexity of managing multiple adapters increases and the ease of operation decreases
Solution Approach 1:
The patent combines multiple power adapter functions into a single integrated charging station with multiple docking bays. The charging station consolidates what would otherwise require multiple separate adapters, allowing users to charge multiple devices simultaneously through one unified device rather than managing multiple individual adapters.
Solution Approach 2:
The charging station is designed with universal compatibility to charge various types of devices including video game controllers, smartphones, tablets, and other portable electronics. The multiple docking bays and various connection interfaces (USB, mini-USB, micro-USB, FireWire) enable the single device to perform multiple charging functions for different device types.
2Volume of moving object
If small plugs are used on accessory devices, then the device size can be reduced, but the reliability of the connection decreases as plugs become fragile and easily damaged
Solution Approach 1:
The charging station incorporates protective features including recessed docking bays that cushion and protect the connection process. The docking bays are designed to guide and receive connectors gently, preventing the kind of forceful insertion that damages small plugs. This protective design compensates for the inherent fragility of small connectors.
Solution Approach 2:
The charging station acts as an intermediary between the power source and the accessory devices. Rather than requiring direct connection between small fragile plugs and power sources, the charging station provides a buffered connection interface that protects the delicate connectors while still enabling reliable power transfer through its robust docking structure.
3Ease of operation
If battery-powered accessory devices are used for portability, then the devices can be used without power supply connection, but the duration of operation decreases due to frequent battery draining requiring replacement or recharging
Solution Approach 1:
The charging station enables preliminary charging of devices before they are needed for use. Users can charge multiple devices in advance, ensuring they are fully powered before portability is required. This preliminary action eliminates the interruption of operation due to battery depletion.
Solution Approach 2:
The charging station maintains continuous availability of powered devices through simultaneous charging of multiple units. While one device is being used portably, other devices can be charging in the docking bays, ensuring continuous operational readiness without interruption to the user's activity.
