Camera Holder for LCD Viewer Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic apparatuses with camera modules, such as liquid-crystal televisions, face challenges in accurately positioning the camera relative to the display panel to capture viewer data effectively, leading to potential distortions in video image control.
Innovation Solution
A camera module is securely mounted on a camera holder attached to the outer frame of the liquid-crystal display module, allowing for precise positioning and stabilization, with the camera's optical axis inclined to ensure the viewer's position is captured accurately, and the module is designed to maintain a consistent positional relationship with the screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the camera module is mounted on the housing without a dedicated holder, then the device complexity is reduced, but the manufacturing precision and positional relationship between camera and panel deteriorate
Solution Approach 1:
The mounting structure is segmented into separate functional components: a camera holder with positioning protrusions and a corresponding holder receiving portion on the housing. This segmentation allows independent optimization of positioning precision and assembly ease, resolving the contradiction between structural simplicity and manufacturing precision.
2Device complexity
If the camera holder is integrated with the housing, then the device complexity is reduced, but the stability of camera position deteriorates
Solution Approach 1:
The holder is designed with elastic deformation capability, allowing it to dynamically adapt to positioning requirements while maintaining stable camera mounting. The elastic holder body can compensate for minor misalignments and maintains consistent contact pressure, ensuring position stability without requiring complex rigid integration with the housing.
3Ease of operation
If the camera optical axis is positioned horizontally, then the ease of operation is improved, but the measurement precision of viewer position deteriorates
Solution Approach 1:
The optical axis inclination angle is adjusted as a key parameter to optimize viewer position detection. By setting the optical axis at a specific inclination angle rather than horizontal, the system achieves better measurement precision for viewer position while maintaining operational simplicity through automated adjustment mechanisms.
