Solution Overview
Problem
Conventional display devices face challenges in maintaining optimal viewing angles and achieving a slim form factor while providing a 3D effect, immersion effect, and presence effect, especially when the user's location varies.
Innovation Solution
A display device comprising a cradle with a signal transmission unit and a display module with a curved shape, where the display module can move along a circle of curvature, allowing for decoupling and slide-coupling states to ensure optimal viewing angles and slimness, with the cradle and display module being individually manageable.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display module is made curved to provide 3D effect and immersion effect, then the viewing angle and user experience are improved, but the device complexity and structural difficulty increase
Solution Approach 1:
The display module is designed to be movable along the circular arc trajectory rather than being fixed in a static curved position. The driving assembly enables dynamic adjustment of the display module's position, allowing it to maintain optimal viewing angles while reducing the need for complex fixed curved structures. This dynamic approach resolves the contradiction by providing adaptability through motion rather than through static structural complexity.
Solution Approach 2:
The system is divided into separate functional modules: the cradle assembly, the display module, and the driving assembly. This segmentation allows each component to be optimized independently - the display module can be curved for viewing angle while the driving assembly handles the complexity of movement control. The modular structure reduces overall system complexity by distributing functional requirements across separate units.
2Adaptability or versatility
If the display module can move along the circle of curvature to maintain optimal viewing angle, then the viewing experience is improved, but the device structure becomes more complex
Solution Approach 1:
The display module moves along a circular arc trajectory that matches its curved shape, allowing it to maintain consistent orientation relative to the user's viewing position. The first and second coupling members are designed with curved geometries that guide this circular motion, enabling viewing angle adaptation through smooth arc-based movement rather than complex multi-axis mechanisms. This curvature-based approach simplifies the coupling mechanism while achieving adaptability.
Solution Approach 2:
The coupling members act as intermediary components between the driving assembly and the display module. These coupling members translate the driving force into the desired circular arc motion, mediating the interaction between the motor system and the display module. This intermediary mechanism simplifies the overall structure by providing a dedicated interface that handles the complexity of curved path following.
3Ease of repair
If the cradle and display module are decoupled for individual management, then the ease of repair and maintenance are improved, but the structural stability may be affected
Solution Approach 1:
The system is divided into separable modules - the cradle assembly and the display module - that can be independently removed and reattached through the coupling members. This segmentation enables easy repair and maintenance of individual components without affecting the entire system. The modular design maintains structural stability when assembled while providing ease of disassembly for maintenance purposes.
Solution Approach 2:
The coupling members provide a dynamic connection that allows the display module to be both securely attached during operation and easily detached for maintenance. The coupling mechanism transitions between a stable connected state during use and a separable state during maintenance, resolving the contradiction between structural stability and ease of repair through conditional connectivity.

AI summary
A display device includes a cradle and a display module. The cradle includes a signal transmission unit configured to transmit an image signal, a housing exposing the signal transmission unit. The display module has a curved shape along a radius of a curvature and includes a signal reception unit configured to receive the image signal, an image display unit configured to display an image based on the image signal, and a second coupling member. The display device is configured to operate in any one of a first state and a second state, in which during the first state, the cradle and the display module are decoupled from each other, and in which during the second state, the first coupling member and the second coupling member are slide-coupled to each other, such that the display module moves along the circumference of a circle of the curvature of the display module.
