Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display apparatuses with integrated cameras face privacy and security issues, and the cost of installation can deter marketability.
Innovation Solution
A display apparatus that includes a rotatable display module and a mounting device for external mobile devices, utilizing the mobile device's camera module to provide a mirror mode without an integrated camera, and automatically pairs with the mobile device for seamless operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a camera is installed in the display apparatus, then the user can photograph himself/herself to produce contents or check gestures in real time, but privacy invasion and security issues may be caused
Solution Approach 1:
The camera functionality is extracted from the display apparatus and relocated to an external mobile device. The mounting device provides a physical interface to attach the mobile device to the display apparatus, allowing the camera to be externally positioned. This extraction eliminates the privacy concerns associated with an integrated camera while preserving the self-photography and gesture monitoring functions.
Solution Approach 2:
The mounting device serves as an intermediary between the display apparatus and the mobile device. It provides a mechanical interface (mounting portion with contact parts) to securely attach the mobile device to the display apparatus frame, enabling the camera functionality to be bridged from an external source without requiring integration into the display apparatus itself.
2Adaptability or versatility
If a camera is installed in the display apparatus, then the user can use camera functions, but the cost for installation increases
Solution Approach 1:
The mounting device provides a universal interface that can accommodate various mobile devices with different camera specifications. Rather than installing a dedicated camera in the display apparatus, the system uses the existing camera modules in commercially available mobile devices, which users already own. This multi-functional approach allows the display apparatus to leverage existing hardware resources.
Solution Approach 2:
The mobile device that the user already owns and carries serves its own purpose (communication, photography, etc.) and simultaneously provides camera functionality for the display apparatus when mounted. The mobile device's existing camera module is utilized without requiring additional camera installation in the display apparatus, thereby avoiding increased manufacturing costs.
3Adaptability or versatility
If the display module is fixed in one orientation, then the structure is simple, but the screen cannot adapt to various image ratios
Solution Approach 1:
The support device incorporates rotational capability that allows the display module to dynamically change its orientation. The motor-driven rotation mechanism enables the display module to switch between different orientations (e.g., portrait and landscape modes), adapting to various image ratios and viewing preferences while maintaining a relatively simple overall structure.

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.
