Display Panel Housing Alignment for Screw-Fastened Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing display device assembly process is burdensome due to the need for visual positioning of through holes and screw holes, which can lead to an increase in the size of the display device.
Innovation Solution
A display device design where the display panel and device housing include matching positioning parts, with the display panel having a recessed area and the housing having a protruded part, allowing for screw fixation without increasing the device's size by aligning the recessed part with the protruded part, enabling precise positioning and fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If visual positioning of through hole and screw hole is used for assembly, then assembly process is simple without additional positioning parts, but work burden on worker increases and assembly precision decreases
Solution Approach 1:
The positioning parts enable the display panel and device housing to self-position during assembly. The protruded positioning part on one component fits into the recessed positioning part on the other component, automatically aligning the through hole and screw hole without requiring visual positioning by the worker. This self-positioning mechanism reduces assembly burden while maintaining structural simplicity.
2Ease of operation
If positioning parts (protruded part and recessed part) are added to enable automatic positioning, then assembly ease improves and positioning precision increases, but device size increases
Solution Approach 1:
The positioning parts are designed with localized protrusions and recesses at specific positions on the display panel and device housing. Rather than adding overall bulk to the device, the positioning features are concentrated in small, targeted areas that minimally impact the overall device volume while providing effective positioning functionality.
3Manufacturing precision
If positioning parts are added to align through hole and screw hole, then positioning precision improves, but device complexity increases
Solution Approach 1:
The positioning function is merged with the existing structural components of the display panel and device housing. The positioning parts are integrated into the housing and panel structures themselves, rather than being separate additional components. This merging approach achieves precise positioning while minimizing increases in overall device complexity.

AI summary
A display device includes a display panel that includes a first hole and a device housing that is configured such that the display panel is fastened and fixed to the device housing by a screw passed through the first hole and screwed into the screw hole. The display panel includes a display-side positioning part which is configured to fit to a portion of the device housing to perform positioning of the display panel with respect to the device housing and which includes the first hole, and the device housing includes a housing-side positioning part which is configured to fit to the display-side positioning part to perform the positioning and which includes a second hole formed so as to communicate with the first hole when the housing-side positioning part is fitted to the display-side positioning part.
