Z-Fold Display Panel With Nested Camera Housing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Z-folding display devices face issues with increased thickness, vulnerability to external impacts, and difficulty in handling due to protruding cameras and reduced battery capacity when trying to reduce thickness.
Innovation Solution
A display panel design with a first, second, and third panel area coupled via hinges, featuring an outer body with a transparent cover and integrated components like a camera, speaker, and illuminometer, allowing for protection and ease of handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the thickness of the main body of the display panel is reduced, then the overall device thickness decreases, but the battery capacity is reduced
Solution Approach 1:
The display device is divided into multiple functional modules: display panel, outer body, battery, camera, and transparent cover as separate components that can be independently positioned and configured, allowing optimization of each component's placement to achieve thin profile while maintaining battery capacity
Solution Approach 2:
Components are redistributed across different spatial dimensions and layers - the battery is positioned in the non-active area of the display panel, the camera is integrated into the outer body, and the transparent cover provides protection without adding significant thickness, enabling thin design while preserving functional capacity
2Length of moving object
If the camera is integrated into the main body, then the device thickness is reduced, but the camera may protrude outwardly and be prone to damage
Solution Approach 1:
The camera is nested within the outer body structure, which acts as a protective housing. The outer body encloses the camera module, providing mechanical protection while maintaining a compact integrated form factor that does not increase overall device thickness
Solution Approach 2:
The outer body serves as a pre-established protective structure that cushions and protects the camera from external impacts and damage before such damage can occur, allowing the camera to be integrated into the main body without compromising reliability
3Area of moving object
If the display screen size is increased, then the display area is expanded, but the device becomes difficult to handle with one hand
Solution Approach 1:
The outer body is designed with enhanced local properties - it has greater thickness and vertical dimension than the display panel, creating a ergonomic handle region that provides grip and leverage for one-handed operation while the display area remains large
Solution Approach 2:
The solution moves from the two-dimensional display plane to the third dimension by creating a protruding outer body structure that serves as a handle, allowing large display screens to be easily handled with one hand through ergonomic design in the vertical dimension
4Device complexity
If the outer edge of the screen is exposed to the exterior, then the device structure is simplified, but the screen is vulnerable to external impact or scratch
Solution Approach 1:
The outer body serves multiple functions simultaneously: it acts as a protective housing for the camera, provides a ergonomic handle for handling, and serves as structural support for the display panel, thereby protecting the screen without significantly increasing device complexity
Solution Approach 2:
The transparent cover and outer body provide pre-established protection for the display screen against external impacts and scratches before such damage can occur, while maintaining a relatively simple overall device structure
