Hinged Printer Display Mount for Flexible POS Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional POS system printer stands limit the visibility and flexibility of display devices, require large installation spaces, and increase costs due to the need for additional components and fixed installation positions, while separate display devices can be prone to instability and require separate installation spaces.
Innovation Solution
A printer design featuring a printer housing with a removable display device mounted to the back surface, connected via a cable, and equipped with a hinge mechanism allowing the display to rotate 180°, enabling flexible orientation and installation without a separate stand, thus enhancing visibility and reducing space and cost requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the display device is fixed to the back surface side of the printer stand, then the printer stand structure is simplified, but the viewing angle and visibility of the display device are limited
Solution Approach 1:
The display device is equipped with a hinge mechanism that enables it to rotate between a horizontal position (parallel to the back surface) and a vertical position (perpendicular to the back surface). This dynamic positioning capability allows the display to adapt to different viewing requirements while maintaining a simplified fixed-structure design, resolving the contradiction between structural simplicity and viewing flexibility.
2Ease of operation
If a printer stand is used to support both the printer and display device, then installation is convenient, but large installation space is required and costs increase
Solution Approach 1:
The display device is directly mounted to the back surface of the printer body, merging the printer and display into a single integrated unit. This eliminates the need for a separate printer stand, reducing the installation space required while maintaining installation convenience through direct mounting.
3Ease of operation
If the display device is mounted to the front surface side of the printer, then visibility is improved, but the display is not visible to persons receiving printed matter
Solution Approach 1:
The hinge mechanism allows the display to rotate between horizontal and vertical positions. When horizontal, the display faces forward for general visibility; when vertical, it can be oriented to face persons receiving printed matter. This dynamic adjustment capability enables the display to adapt to different usage scenarios and user positions.
4Adaptability or versatility
If the display device is separably mounted to the printer, then flexibility and visibility are improved, but device complexity increases
Solution Approach 1:
The hinge mechanism provides a simple yet effective mounting structure that enables both fixed and adjustable positioning. The hinge connects the display to the printer's back surface through a straightforward rotational joint, achieving separable and flexible mounting without significantly increasing structural complexity.

AI summary
A printer includes a printer housing, which includes a plurality of outer surfaces including a bottom surface opposed to an installation surface, and has a recording paper receiving portion configured to receive recording paper through an opening portion; a printer cover, which is coupled to the printer housing, and is configured to openably cover the opening portion; a printer display device, which is removably mounted to the outer surface, of the plurality of outer surfaces, other than the bottom surface, and is configured to display predetermined information; and a connection cable, which is connected between the printer housing and the printer display device, and is configured to communicate at least data related to the predetermined information. The printer display device includes a fixing portion separably mounted to the outer surface; a display portion main body having a display portion configured to display the predetermined information provided thereon; and a hinge portion configured to couple the fixing portion and the display portion main body to each other so that the display portion main body is displaced relative to the fixing portion.
