Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a connection method supporting multiple cable types (USB, Micro USB, Lightning) is implemented, then adaptability is improved, but device complexity increases due to multiple connection terminals and protocols
Solution Approach 1:
The connection terminal is designed to support multiple cable types (USB type-C, Micro USB, Lightning) through a single unified interface structure. The terminal includes multiple contact pads that can detect and establish connections with different cable types, allowing one terminal to perform multiple functions that would traditionally require separate terminals for each cable type.
2Ease of operation
If connection priority is determined by insertion order, then ease of operation is improved, but reliability deteriorates due to inconsistent connection quality
Solution Approach 1:
The processor detects which cable type is actually inserted by monitoring contact pad connections and determines connection priority based on this feedback information. The system dynamically adjusts which terminal serves as the primary connection based on the detected cable type, ensuring reliable data transmission regardless of insertion order. This feedback mechanism allows the system to adapt to the actual connection state and maintain consistent connection quality.

AI summary
This application discloses an input device connection method, a device, and a system, and relates to the field of terminal technologies, to reduce operation complexity of inputting information to a plurality of devices, and improve input efficiency. In this application, a same input device may randomly switch a focus device between a plurality of terminal devices. Before and after the focus device is switched, the input device may simultaneously maintain communication connections to the plurality of terminal devices, and exchange, in a background, information with a non-focus device based on a communication connection between the input device and the non-focus device. Based on the solutions disclosed in this application, the input device can implement seamless focus migration between the plurality of terminal devices based on a convenient operation of a user without relying on a wireless local area network (wireless local area network, WLAN), to ensure that no interface display freezing occurs during switching, and implement an effect of seamless continuation of the input device across devices.
