Sliding Webcam Mount for Direct Table Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional webcam mounts allow the lens to capture a part of the screen when facing a table directly, resulting in trapezoidal images due to non-right angles, requiring post-production correction.
Innovation Solution
A mount with a first base body, a second base body rotatably connected to the first, a third base body slidably matched to the second, and a fourth base body rotatably connected to the third, allowing the webcam to slide away from the display and rotate 90° to face the table directly, preventing screen capture and image distortion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the webcam is mounted on the top of the display with a conventional movable base body, then the webcam can rotate to adjust viewing angles, but the lens cannot face the table directly without capturing part of the display screen
Solution Approach 1:
The mount is divided into multiple independent base bodies (first, second, third, and fourth base bodies) that can move relative to each other. The third base body can slide relative to the second base body, and the fourth base body can rotate relative to the third base body, allowing independent adjustment of position and orientation to resolve the contradiction between viewing angle adjustment and image quality.
Solution Approach 2:
The mount incorporates dynamic movement capabilities where the third base body can slide along the second base body and the fourth base body can rotate relative to the third base body. This dynamic structure allows the lens to be positioned at optimal distances and angles, enabling direct facing of the table while avoiding screen capture and ensuring high image quality.
2Device complexity
If the webcam is positioned close to the display for mounting convenience, then the mount structure is simple, but the lens captures part of the screen when facing the table
Solution Approach 1:
The invention adds a sliding dimension between the third base body and second base body, allowing the webcam assembly to move forward or backward relative to the display. This additional degree of freedom enables the lens to be positioned at an optimal distance from the display surface, preventing screen capture while maintaining a relatively compact overall structure.
3Manufacturing precision
If the webcam is rotated to face the table directly, then the image quality improves, but the lens still captures part of the display screen due to mounting position
Solution Approach 1:
The invention extracts the positioning function from the fixed mounting structure by introducing a sliding mechanism. The third base body can slide independently of the rotation mechanism (fourth base body), allowing the lens to be positioned at the optimal distance from the display before rotation. This separation of positioning and orientation functions enables direct facing of the table with proper perpendicular alignment, eliminating trapezoidal distortion while maintaining high image quality.

AI summary
Provided is a mount for a webcam for installing the webcam on a computer display, and the webcam set on the mount can be moved in a horizontal direction to an appropriate distance beyond the display and then rotated 90°, so that a camera lens of the webcam can be vertically oriented downward to capture an image on a table, so as to avoid capturing a part of the screen of the display, or causing the captured image distortion.
