Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices with camera modules face challenges due to complex structures, increased size, high assembly costs, and potential defects from narrow spaces and cable issues when using latches and dampers for pop-up mechanisms.
Innovation Solution
A display device design featuring a sliding image capturing unit guided by a torsion spring, eliminating the need for latches and dampers, with a guide body and torsion spring that applies elastic force to facilitate easy sliding between accommodated and protruding positions, and includes a cushion part to minimize shock and cable guides to prevent tangling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a latch and a damper are disposed inside the pull-in part to enable pop-up operation of the video communication camera, then the camera can be pushed up and down, but the size of the pull-in part is increased and the structure becomes complicated making assembly difficult and cost high
Solution Approach 1:
The invention extracts and eliminates the latch and damper components from the pull-in part, replacing them with a simplified guide body structure that guides the camera module along a predetermined path without requiring additional locking or damping mechanisms inside the pull-in part
Solution Approach 2:
The guide body serves multiple functions: it guides the camera module during pop-up operation, provides structural support, and replaces the combined functions of the latch and damper, thereby simplifying the overall structure while maintaining operational capability
2Ease of operation
If a latch and a damper are used for the camera push up/down mechanism, then the camera can be positioned, but the assembly space is narrow leading to increased work man-hour and potential defects when cable is connected
Solution Approach 1:
The invention segments the camera module assembly from the latch and damper mechanisms, allowing the camera to be positioned through the guide body's structural guidance while cables can be independently managed outside the narrow pull-in space, thereby improving assembly ease and reducing defects
Solution Approach 2:
The guide body acts as an intermediary structure that provides mechanical guidance and positioning for the camera module without requiring the complex interaction between latch, damper, and cable in the narrow pull-in space, thereby facilitating easier assembly and reducing assembly time
3Device complexity
If a simple structure without latch and damper is used, then assembly is easier and cost is reduced, but the camera module needs reliable guidance and positioning mechanism
Solution Approach 1:
The guide body is designed with a predetermined curved path that dynamically guides the camera module through its pop-up and retraction movements, ensuring reliable positioning at each stage of motion without requiring static locking mechanisms like latches
Solution Approach 2:
The invention replaces the mechanical latch and damper system with a geometrically constrained guide body structure that uses the shape and orientation of guiding surfaces to provide reliable guidance and positioning, thereby simplifying the structure while maintaining reliability

AI summary
A display device according embodiment of the present disclosure may include a display main body, an image capturing unit which slides between a first position accommodated inside the display main body and a second position protruding outside the display main body, a guide body provided inside the display main body and slidingly guiding the image capturing unit, and a torsion spring connecting the image capturing unit and the guide body to apply an elastic force to the image capturing unit. The direction of the elastic force applied to the image capturing unit by the torsion spring may change when the image capturing unit passes through a third position located between the first position and the second position.
