Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inconvenience in carrying multiple power adaptors for electronic devices with different voltage requirements, as existing adaptors cannot be used interchangeably.
Innovation Solution
A power adaptor design featuring a replaceable tip with varying terminal configurations, allowing the adaptor body to output different voltage levels by changing the short-circuit connections between conductive elements and terminals, enabling a single adaptor to support multiple devices with distinct voltage needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If users carry multiple power adaptors for different voltage requirements, then each electronic device can be charged with the appropriate voltage, but the burden of carrying and managing multiple adaptors increases
Solution Approach 1:
The power adaptor is designed with a universal body that can work with multiple types of tips, allowing a single adaptor to charge electronic devices with different voltage requirements. The adaptor body contains voltage recognition circuitry that can identify the required voltage through different tip configurations (such as different terminal connections), enabling one adaptor to perform multiple voltage output functions.
Solution Approach 2:
The power adaptor is divided into two separable parts: a universal adaptor body and interchangeable tips. The tip portion contains the voltage-specific connection terminals, while the adaptor body contains the power conversion and control circuitry. This segmentation allows users to keep one adaptor body and only swap the small, lightweight tips to match different voltage requirements, reducing the overall burden compared to carrying multiple complete adaptors.
2Adaptability or versatility
If a single power adaptor is designed to support multiple voltage levels, then the need for multiple adaptors is reduced, but the internal circuit complexity of the adaptor increases
Solution Approach 1:
The tip acts as an intermediary component that carries voltage identification information to the adaptor body. Instead of requiring the adaptor body to have complex switching circuitry for all voltage levels, the tip's physical configuration (terminal connections, contact patterns) serves as a simple mechanical mediator that tells the adaptor body which voltage to output, reducing the control complexity.
Solution Approach 2:
The system uses passive voltage recognition where the tip's physical structure itself encodes the voltage information through its terminal connections. The adaptor body's control circuit automatically detects the tip configuration and self-adjusts the output voltage without requiring complex user input or sophisticated control algorithms, enabling multi-voltage support through simple automatic recognition.

AI summary
A power adaptor includes an adaptor body, an output connector, and a replaceable tip. The output connector is connected to the adaptor body. The replaceable tip is detachably connected to the output connector. The replaceable tip includes four terminals, a first conductive element, and a second conductive element. The first conductive element is connected to two or three of the terminals. The second conductive element is connected to at least one of the remaining terminals. The adaptor body outputs an output voltage depending on the replaceable tip.
