Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple different input devices are used simultaneously with specified functions only, then each device can perform its dedicated function reliably, but the devices cannot be connected with each other or cooperatively operated, reducing system versatility
Solution Approach 1:
The input devices are designed with universal connecting ports that can connect to both external power sources and other input devices. The power switching circuit enables the same port to serve multiple functions: receiving power from external sources or transmitting power to connected devices, thereby achieving multi-functionality and cooperative operation without increasing connection complexity
Solution Approach 2:
The power switching circuit acts as an intermediary component that mediates between the connecting port and the power source/connected device. It intelligently switches between receiving power from an external source and transmitting power to a connected input device, enabling cooperative operation while maintaining a simple connection structure
2Ease of operation
If each input device is individually connected with external power sources, then each device can operate independently, but the connection structure becomes complex and not user-friendly
Solution Approach 1:
Multiple input devices are merged into a cooperative system where one device can serve as a power source for another. Instead of each device requiring its own external power connection, the system allows power to be shared through device-to-device connections, simplifying the overall power connection structure and improving ease of operation
Solution Approach 2:
Input devices are designed to serve themselves and each other in the power supply chain. A device that is connected to an external power source can automatically serve as a power source for connected devices without requiring additional external power connections, enabling the system to self-organize power distribution

AI summary
An input system includes a first input device and a second input device. Each of the first input device and the second input device includes a main body, a first connecting port, at least two second connecting ports, a power switching circuit and a control unit. When the first connecting port of the first input device is connected with an external power source, the power switching circuit of the first input device receives a first voltage from the external power source. When one of the second connecting ports of the first input device is connected with one of the second connecting ports of the second input device, the first voltage is converted into a second voltage by the power switching circuit of the first input device and the second voltage is transmitted to the second input device.
