Problem
Current mobile terminals lack efficient methods for controlling the operation and state of main devices when coupled or separated from sub-devices, leading to limitations in functionality and user experience.
Innovation Solution
A mobile terminal system that includes a sub-device with an input/output unit and a controller to establish a communication path for user input, allowing for control of terminal elements and applications when the sub-device is attached or detached, enabling seamless operation and state management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a sub-device is detachably attached to the mobile terminal, then the functionality and versatility of the terminal is improved, but the device complexity increases
Solution Approach 1:
The mobile terminal is divided into a main device and a separable sub-device. The sub-device can be detached from the main device, allowing users to customize their experience by attaching or detaching the sub-device based on specific needs. This segmentation enables functional versatility while maintaining a relatively simple base structure.
Solution Approach 2:
The sub-device is designed with universal functionality that can be applied across different main devices. The sub-device includes a controller, display unit, and communication unit that can operate independently or in conjunction with the main device, providing multi-functional capabilities such as remote control, additional display, and enhanced interaction modes.
2Ease of operation
If the sub-device is separated from the main device, then the ease of operation is improved through wireless control, but the loss of information may occur during communication
Solution Approach 1:
The communication unit in the sub-device establishes a wireless communication path with the main device to transmit user inputs and status information. The controller in the sub-device receives feedback signals from the main device, enabling real-time coordination and reducing information loss through continuous data exchange between the separated devices.
3Ease of manufacture
If the terminal uses modularized structure, then the ease of manufacture is improved, but the reliability of connection between main device and sub-device deteriorates
Solution Approach 1:
The sub-device is designed to nest within or attach to the main device through a standardized interface. The coupling structure allows the sub-device to be securely integrated into the main device body, ensuring reliable connection while maintaining ease of assembly and disassembly for manufacturing purposes.
