Convertible Device Hinge and Camera Nesting for Bezel Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Convertible electronic devices face challenges in minimizing bezel area and preventing interference between housings when folded, while maintaining a wide display screen and comfortable user experience.
Innovation Solution
The design incorporates a display module with distinct light transmittance regions and a camera module positioned on the rear surface, housed in a structure that allows for thin bezels and interference prevention through a hinge mechanism enabling multiple folding states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the camera module is positioned on the rear surface of the display module to overlap the first region, then the bezel area is reduced, but the device complexity increases due to the need for precise alignment and additional housing structures
Solution Approach 1:
The camera module is nested within the display module structure by positioning it on the rear surface to overlap the first region. The camera module accommodating portion in the first housing creates a nested configuration where the camera module is housed within the overall display assembly, reducing the need for separate housing structures and minimizing bezel area.
Solution Approach 2:
The camera module is positioned in the thickness direction by overlapping the first region, transitioning from a planar arrangement to a three-dimensional configuration. This vertical stacking approach allows the camera module to share the same footprint area as the display region, thereby reducing bezel area without increasing the device's planar dimensions.
2Manufacturing precision
If the first housing includes a camera module accommodating portion protruding to an outside to overlap the camera module, then the camera module can be properly positioned, but the housing complexity increases
Solution Approach 1:
The camera module accommodating portion is pre-formed in the first housing with the specific protruding structure needed to position the camera module. This preliminary preparation of the housing structure ensures that when the camera module is installed, it automatically achieves the correct position and orientation, maintaining manufacturing precision while simplifying the assembly process.
Solution Approach 2:
The first housing features a localized protruding camera module accommodating portion only in the specific region where the camera module needs to be positioned. This localized structural modification maintains the overall simplicity of the housing while providing the necessary precision positioning feature exactly where needed, without adding complexity to the entire housing structure.
3Adaptability or versatility
If the first housing and second housing are configured to overlap in multiple folded states, then the device versatility is improved, but the risk of housing interference increases
Solution Approach 1:
The hinge member enables dynamic configuration of the convertible electronic device, allowing the first housing and second housing to rotate relative to each other and achieve multiple stable folded states. This dynamic capability provides versatility for different usage modes (laptop mode, tablet mode, tent mode, etc.) while the hinge's mechanical design ensures proper spacing and alignment to prevent housing interference in each state.

AI summary
A convertible electronic device includes a display module including a first region and a second region surrounding the first region and having a lower light transmittance than the first region; a camera module disposed on the display module to overlap the first region; a first housing which accommodates the display module therein, and includes a camera module accommodating portion protruding outwardly to overlap the camera module; a keyboard; a second housing which accommodates the keyboard therein; and a hinge member connecting the first housing to the second housing rotatably to each other with respect to a rotation shaft. The first and second housings are in a first folded state where the first and second housings overlap each other to allow front surfaces to face each other or in a second folded state where the first and second housings overlap each other to allow rear surfaces to face each other.
