Solution Overview
Problem
Standard connectors in electronic devices provide a fixed voltage and current, limiting the ability to adjust power supply to meet varying current requirements of external devices, and existing workarounds like 'Y' type connecting wires are inconvenient for users.
Innovation Solution
An electronic device with multiple connectors, switching units, a control unit, and a user interface that allows selective adjustment of current supply to external devices based on their requirements, using a detecting unit to assess power parameters and manage power consumption to prevent overload.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If standard connectors are used with fixed voltage and current, then the electronic device structure remains simple and reliable, but the ability to adjust power supply to meet varying current requirements of external devices is limited
Solution Approach 1:
The patent implements dynamic current supply by using switching units that can dynamically connect different current paths based on the power requirements of external devices. The control unit receives power parameter information from external devices and dynamically switches between different current supply modes (first current, second current, or third current), transforming a static connector system into a dynamic one that adapts to varying power needs.
Solution Approach 2:
The patent makes the first connector multi-functional by enabling it to provide different current levels (first current, second current, or third current) depending on the requirements of the connected external device. Through the switching units and control logic, a single connector type can serve multiple power delivery functions, eliminating the need for multiple specialized connectors.
2Power
If multiple connectors are used to provide higher current, then the current supply capability increases, but the device complexity and user operation difficulty increase
Solution Approach 1:
The patent implements self-service operation by enabling the electronic device to automatically detect power parameters of external devices through the detecting unit and autonomously switch between different current supply modes via the control unit and switching units. Users simply connect the external device to the first connector, and the system automatically provides the appropriate current level without requiring users to manually select connectors or configure settings.
3Power
If a Y type connecting wire is used to provide more current, then the current limit problem is overcome, but the convenience for users to carry and use the additional connecting wire deteriorates
Solution Approach 1:
The patent merges multiple current supply paths (first connector, second connector, third connector) into a single functional interface (first connector) that can deliver combined current levels. Instead of requiring users to physically combine multiple connectors using a Y-type wire, the switching units internally merge the current paths and deliver the combined power through the single first connector, maintaining portability and ease of use.
4Power
If the connector provides higher current, then the power delivery to external devices improves, but the risk of overload and the need for protective circuits increases
Solution Approach 1:
The patent implements preliminary protection by having the detecting unit detect power parameters of external devices before the control unit activates higher current supply modes. The system preliminarily assesses the power requirements and compatibility of the external device, then proactively switches to the appropriate current level, preventing overload conditions before they occur rather than relying solely on reactive protective circuits.
