Rotatable Device Module for High Screen-to-Body Ratio Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display apparatuses have a low screen-to-body ratio due to the placement of necessary devices like cameras and flash lamps, which reduces the display area and affects the display effect.
Innovation Solution
A display apparatus with a rotatable device module that includes a second display screen and a functional device positioned in a non-light-exiting direction, allowing the first and second display screens to be positioned on the same side, thereby increasing the screen-to-body ratio when the functional device is not in use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If devices such as earpiece, camera, and flash lamp are arranged on the same side as the display screen, then the display screen area is reduced, but the screen-to-body ratio is improved
Solution Approach 1:
The device module is made rotatable relative to the apparatus body, allowing dynamic repositioning between different orientations. When rotated to a first position, the second display screen aligns with the first display screen to maximize display area. When rotated to a second position, the functional device faces the user for interaction, resolving the contradiction between display area and device accessibility
Solution Approach 2:
The solution moves from a two-dimensional planar arrangement to a three-dimensional spatial configuration by rotating the device module around an axis. This allows the second display screen and functional device to occupy different spatial positions, enabling both screens to be visible simultaneously while keeping the functional device accessible when needed
2Area of stationary object
If the device module is made rotatable to position both display screens on the same side, then the screen-to-body ratio is improved, but the device complexity increases
Solution Approach 1:
A rotatable connection mechanism is introduced between the device module and apparatus body, replacing fixed rigid connections. This dynamic joint allows the device module to rotate between positions, achieving high screen-to-body ratio when both screens are aligned, while adding only moderate mechanical complexity through standardized rotating components
Solution Approach 2:
The device module serves multiple functions: it can be rotated to align the second display screen with the first for maximum display area, or rotated to present the functional device to the user for interaction. This multi-functionality justifies the added rotational mechanism complexity by providing flexible adaptability
