Display Device Lid Inversion for Component Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices are difficult to service as they require lifting and positioning upside down, which can damage the screen and is cumbersome for users, especially when accessing internal components for maintenance or upgrades.
Innovation Solution
A display device architecture that allows the screen to pivot to a horizontal servicing position, supported by a stand, with a hinge assembly enabling the lid to open and provide access to internal components without lifting the device, using mechanisms like lift assists and sliding supports for easy access and reassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the display device is placed upside down for servicing, then access to internal components is enabled, but the screen may be damaged and the process is cumbersome
Solution Approach 1:
Instead of inverting the entire display device to access internal components, the patent inverts only the lid portion containing the screen. The lid pivots 180 degrees to position the screen horizontally above the base, allowing access to internal components through the base while the screen remains in a protected horizontal orientation rather than being subjected to the harmful effects of complete device inversion.
Solution Approach 2:
The display device is divided into separable components: a base containing internal components and a lid containing the screen. This segmentation allows the lid to be independently manipulated and positioned for servicing without requiring the entire device to be inverted, enabling selective access to different components while protecting vulnerable parts.
2Ease of repair
If the display device is lifted for servicing, then access to internal components is enabled, but the process becomes cumbersome for users
Solution Approach 1:
The patent applies inversion selectively to the lid rather than requiring users to lift and invert the entire heavy device. The lid pivots 180 degrees to a horizontal position above the base, allowing users to access internal components through the base while the screen remains horizontally positioned for protection. This eliminates the need for users to manually lift and reposition the complete display device.
Solution Approach 2:
The hinge assembly acts as an intermediary mechanism between the lid and base, enabling the lid to pivot independently without requiring users to manually position the entire device. The hinge provides the mechanical interface that allows the lid to rotate 180 degrees while remaining connected to the base, simplifying the servicing process.
3Device complexity
If the screen is positioned vertically during servicing, then the device structure is simple, but the screen is vulnerable to damage
Solution Approach 1:
The patent inverts the lid 180 degrees so that the screen, originally positioned vertically facing forward, ends up in a horizontal position above the base during servicing. This inversion transforms the screen orientation from a vulnerable vertical position to a protected horizontal position, while maintaining a relatively simple device structure through the use of a standard hinge mechanism.

AI summary
An example display device includes a display device stand and display device housing pivotably connected to display device stand. The display device housing is to pivot between a vertical operating position and a horizontal servicing position, and a lid portion of the display device housing is to rotatably open away from a back portion of the display device housing to provide access to components within the display device housing.
