Curved Display Device Thickness Reduction via PCB Nesting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional curved screen displays have increased thickness due to the depth of the case and the height of electronic components, which affects the overall thickness and usability of the device.
Innovation Solution
A display device design featuring a curved display body with a through hole in the case's bottom plate allows the electronic component to be housed within a gap between the display body and the case, reducing the component's height and thus the device's thickness, by positioning the printed circuit board opposite to the curved part with the electronic component inside the hole.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display body is curved and housed in a case with electronic components mounted on the printed circuit board, then the display device achieves a curved screen display function, but the thickness of the display device increases due to the depth of the case and the height of electronic components
Solution Approach 1:
The electronic component is nested inside the through hole formed in the bottom plate part of the case. The printed circuit board is positioned such that the electronic component is housed within the gap between the display body and the case, effectively hiding the component within the existing structure rather than adding external depth.
Solution Approach 2:
The electronic component is arranged in a different spatial dimension by positioning it inside the through hole of the bottom plate, rather than mounting it on the outer surface of the printed circuit board. This repositions the component from the vertical thickness dimension to the horizontal plane dimension, reducing the overall device thickness.
2Ease of repair
If the electronic component is mounted on the printed circuit board outside the case, then the component is easily accessible and replaceable, but the device thickness increases and aesthetics are compromised
Solution Approach 1:
The electronic component is nested within the through hole of the bottom plate, placing it inside the case structure. This maintains component accessibility for repair while hiding it from external view, improving aesthetics without sacrificing serviceability.
Solution Approach 2:
The through hole in the bottom plate acts as an intermediary structure that accommodates the electronic component. This intermediate space allows the component to be positioned within the case depth, reducing external thickness while maintaining accessibility through the opening.
3Device complexity
If the printed circuit board is drawn to the outside of the case for fixing, then the electrical connection is simplified, but the device thickness and overall size increase
Solution Approach 1:
The printed circuit board is nested within the case structure, with the electronic component positioned inside the through hole. This integration keeps the electrical connection simple while avoiding external protrusions that would increase device thickness.
Solution Approach 2:
The printed circuit board arrangement utilizes the internal space of the case rather than extending externally. By repositioning components from external mounting to internal placement within the through hole, the solution maintains electrical connectivity while reducing the device's external dimensions.
