Inclined Mounting Surface for Printer Operation Panel Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing holding stands for printing devices make it difficult for users to see the display screen and operate the operation buttons due to the orientation of the printing device when mounted, as the operation panel unit is often positioned in a way that is not easily visible or accessible.
Innovation Solution
A holding stand with an inclined mounting surface and a guide part that allows the printing device to be mounted in a way that the operation panel unit faces upward, featuring a fixed engaging member at the upstream end and a movable engaging member in the middle, enabling easy engagement and disengagement of the printing device, and an operation part to switch the movable engaging member between engaging and disengaging positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the mounting surface is made planar and horizontal, then the printing device can be stably mounted, but the operation panel unit becomes difficult for users to see and operate
Solution Approach 1:
The mounting surface is changed from a horizontal plane to an inclined surface, introducing a dimensional change in the orientation of the mounting surface. This inclination angle allows the operation panel to be positioned at a higher vertical level while maintaining stable mounting through the engagement of engaging members with corresponding engaging portions on the inclined surface.
2Ease of operation
If the operation panel is positioned at a higher angle for better visibility, then users can easily see and operate controls, but the mounting structure becomes more complex
Solution Approach 1:
The mounting structure is segmented into multiple functional components: a fixed engaging member for stable anchoring, a movable engaging member for adjustable positioning, and a guide part for alignment. This segmentation allows the complex inclined mounting function to be achieved through coordinated simple components rather than a single complex structure.
Solution Approach 2:
The movable engaging member acts as an intermediary between the fixed engaging member and the printing device. It provides a mechanical linkage that translates the inclination of the mounting surface into proper positioning of the operation panel, mediating the relationship between the inclined surface and the device being mounted.
3Ease of operation
If an inclined mounting surface is used to improve operation panel visibility, then the operation buttons become easily accessible, but the printing device may become unstable
Solution Approach 1:
Multiple engagement functions are merged into a coordinated system: the fixed engaging member provides primary anchoring stability, the movable engaging member provides secondary positioning stability, and the guide part provides alignment stability. This merging of multiple stability-providing features compensates for the potential instability introduced by the inclined surface while achieving improved operation panel visibility.

AI summary
A holding stand including: a housing having a mounting surface on which a printing device is capable of being detachably mounted and a bottom surface, the mounting surface being an inclined surface where a distance between an upstream end portion of the mounting surface and the bottom surface is greater than a distance between a downstream end portion of the mounting surface and the bottom surface; a fixed engaging member provided at the upstream end portion; a movable engaging member provided at a substantially middle portion of the mounting surface; a guide part provided on the mounting surface and configured to allow the printing device to slide thereon to guide the printing device; and an operation part capable of switching the movable engaging member from an engaging position in which the movable engaging member engages with a second engaging portion to a disengaging position in which engagement is disengaged.
