Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display unit is fixedly formed in one body with the main unit, then the structure is simple and stable, but the user's ability to operate the display unit to view image information in various ways is limited
Solution Approach 1:
The display unit is separated from the main unit to form an independent operable unit. The display unit includes a display module, RF receive unit, memory, and controller that can function independently, allowing flexible operation while viewing image information without being constrained by the main unit's structure.
Solution Approach 2:
An RF transmission unit in the main unit and RF receive unit in the display unit establish wireless communication between the separated units. This intermediary communication mechanism enables data transfer without physical connection, maintaining functionality while achieving structural separation for enhanced operability.
2Ease of operation
If the display unit is separated from the main unit, then the user can freely carry and operate the display unit, but wireless data transmission and storage systems are required
Solution Approach 1:
The display unit is extracted as an independent portable unit from the main unit. It contains integrated RF receive unit, memory, and controller that enable it to receive and process data wirelessly, allowing free carrying and operation while managing the complexity through functional integration.
Solution Approach 2:
The display unit is designed with multi-functionality, serving as both a display device and an independent operational unit with RF reception and data storage capabilities. This universal design enables it to function independently while maintaining connectivity with the main unit through wireless transmission.
3Adaptability or versatility
If the display unit is separated from the main unit, then the terminal can be used as a remote display, but additional sensors and controllers are required to sense separation and manage data paths
Solution Approach 1:
Separation sensors in both the main unit and display unit provide feedback on the separation state. The main unit controller and display unit controller use this feedback information to dynamically adjust data transmission paths, enabling remote display functionality while managing system complexity through automated control.
Solution Approach 2:
The system dynamically adjusts its configuration based on the separation state sensed by separation sensors. When separated, the system activates wireless data transmission paths; when connected, it uses direct data paths. This dynamic adaptation enables remote display functionality while managing complexity through state-dependent operation.

AI summary
A mobile terminal that has a display unit separable from a main unit and a method thereof are provided. The main unit includes a first separation sensor for sensing separation of the display unit; a radio frequency (RF) transmission unit for wirelessly transmitting data to be output to the display unit by radio; and a main unit controller for setting a path of the data to be output to the display unit to the RF transmission unit if the separation of the display unit is sensed by the first separation sensor. The display unit includes a second separation sensor for sensing separation from the main unit; an RF receiver unit for receiving data transmitted wirelessly from the RF transmission unit; a display controller for setting a path of the data input to the display unit to the RF receiver unit if the separation from the main unit is sensed by the second separation sensor; a memory for storing the data received by the RF receiver unit; and a display module for displaying the data stored in the memory.
