Bent Display Component Mounting via Filler Penetration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable electronic devices with bended displays face challenges in integrating electronic components in a way that enhances both aesthetics and usability while maintaining a robust assembly process.
Innovation Solution
An electronic device design featuring a housing with a flat area and a bending area on the display, where a filler is used between the housing and the display to expose electronic components, such as a key button assembly, allowing them to penetrate the display for external access, and a detection circuit inside the housing connects these components to control functions based on detected signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If electronic components are installed inside the housing without penetrating the display, then the display surface remains intact and aesthetically pleasing, but the components are not accessible to users for operation
Solution Approach 1:
The electronic component is extracted from the internal housing space and positioned to penetrate through the display surface. This allows the component to be accessible from the outside while maintaining its functional integration within the device structure. The display surface is selectively opened only where needed for component access.
Solution Approach 2:
The electronic component is nested within the display structure, with part of it penetrating through the display surface. The component is positioned such that it is contained within the overall device boundaries while extending outward for user interaction, creating a nested configuration that combines internal integration with external accessibility.
2Ease of manufacture
If a filler is used between the housing and display to install components, then component installation is facilitated, but the assembly process becomes more complex
Solution Approach 1:
The device structure is segmented into distinct functional zones: the housing, the display, and the filler layer. The filler is positioned in the gap between the housing and display, creating a dedicated installation space for electronic components. This segmentation allows components to be installed in the filler layer without requiring complex integration into either the housing or display structures.
Solution Approach 2:
The filler acts as an intermediary layer between the housing and the display. It provides a flexible mounting surface for electronic components, allowing them to be installed and secured without direct attachment to either the rigid housing or the fragile display. This intermediary structure simplifies component installation while maintaining the integrity of the overall assembly.
3Ease of operation
If the display is made fully flexible to allow component penetration, then component accessibility is improved, but the display reliability and durability decrease
Solution Approach 1:
The display structure is designed with different properties in different regions. The area where component penetration is needed has localized flexibility and opening, while the rest of the display maintains its standard structural integrity and durability. This local modification allows component access without compromising the overall reliability of the display.
Solution Approach 2:
Instead of making the entire display flexible or opening it completely, only the specific region where component access is required is modified. The filler and component assembly are positioned to expose only the necessary portion of the component through a controlled opening in the display, providing sufficient accessibility while minimizing impact on display durability.
