Innovation Solution
The display apparatus includes a rotatable display module supported by a motor-driven support device and a mounting device that accommodates a mobile device, allowing the mobile device's camera module to be used for mirror mode functionality without a built-in camera, and automatically pairs with the display module for seamless operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a camera module is installed in the display apparatus, then camera functionality is provided, but privacy and security issues arise and cost increases
Solution Approach 1:
The camera functionality is extracted from the display apparatus and relocated to the mobile device. The mounting device provides a physical interface that securely holds the mobile device, enabling the external camera to capture images while the display apparatus itself contains no camera module, thereby eliminating privacy and security concerns associated with built-in cameras.
Solution Approach 2:
The mobile device serves as an intermediary between the user and the display apparatus for camera operations. The mounting device facilitates this intermediary relationship by providing a dedicated mounting portion with shape-corresponding structure that interfaces with the frame, allowing the mobile device to be positioned optimally for camera functionality while maintaining physical separation from the display apparatus internals.
2Adaptability or versatility
If a camera module is installed in the display apparatus, then camera functionality is provided, but cost increases and marketability deteriorates
Solution Approach 1:
The mounting device is designed with multi-functionality: it provides structural support for the mobile device, enables camera functionality, and incorporates a shape-corresponding mounting portion that interfaces with the frame. This universal design allows the same structure to serve multiple purposes without requiring additional camera-specific components, thereby reducing manufacturing cost.
Solution Approach 2:
The invention leverages the mobile device that the user already possesses, eliminating the need for expensive dedicated camera hardware in the display apparatus. By utilizing the existing mobile device's camera module through the mounting device interface, the solution avoids additional manufacturing costs while maintaining camera functionality.
3Adaptability or versatility
If the display module is fixed in one position, then structure is simple, but it cannot efficiently display various screen ratios
Solution Approach 1:
The support device transitions from a static fixed-position structure to a dynamic rotatable structure. The rotatable mounting device allows the display module to be rotated between landscape and portrait orientations, enabling efficient display of various screen ratios. This dynamic capability is achieved through a rotatable interface that maintains structural integrity while providing rotational freedom.
Solution Approach 2:
The solution adds rotational freedom in the third dimension (rotation around the vertical axis) to the display module positioning. The shape-corresponding mounting portion and frame interface enable rotation without compromising structural stability, allowing the display to adapt to different orientation requirements for various screen ratios.

AI summary
A display apparatus includes a display module, a support configured to rotate and support the display module, and a mounting device configured to mount a mobile device on the display module. The mobile device is configured to be paired with the display module. The mounting device includes a mounting portion including a mounting groove having a shape corresponding to a frame forming borders of the display module. The mounting portion is coupled to the frame when the frame is inserted into the mounting groove, and an accommodating portion is positioned below the mounting portion, and accommodates the mobile device such that the mobile device is mounted on the display module.
