Printer Cover Touch Panel Guard Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information processing devices, such as printers, face issues with unintentional erroneous inputs due to high touch panel sensitivity when the cover is in a closed state, as users may unintentionally contact the touch panel.
Innovation Solution
The design includes a cover with a rotating shaft and frames that pivot to cover the touch panel, with a damper to reduce impact and a second rotating shaft that overlaps the touch panel, ensuring the touch panel is guarded and preventing unintentional inputs by maintaining a parallel and inclined position relative to the cover.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the touch panel sensitivity is kept high for normal operation, then the touch panel responds well to user inputs, but unintentional erroneous inputs occur when the user opens the cover
Solution Approach 1:
The cover is equipped with a touch panel guard that is positioned in advance to cover the touch panel before the user opens the cover. This preliminary action prevents unintentional contact with the touch panel during the cover opening operation, while allowing normal touch panel operation when the cover is closed and the guard is in place
2Ease of operation
If the touch panel is exposed for easy access, then user interaction is convenient, but unintentional contact occurs when opening the cover
Solution Approach 1:
A touch panel guard is introduced as an intermediary component between the cover and the touch panel. The guard is coupled to the cover and positioned to physically block contact between the cover (and user's hand) and the touch panel during cover opening, while allowing the touch panel to remain accessible for intentional input when the cover is closed
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration effectively reduces unintentional inputs by using frames and a damper to protect the touch panel, allowing users to safely open and close the cover without accidentally triggering inputs, enhancing user safety and device functionality.
Implementation Method 1
the cover may be coupled to the housing through a damper configured to attenuate a rotating speed of the cover pivoting about the axis of the first rotating shaft

AI summary
Provided is a printer, which serves as an information processing device and which includes: a housing; a cover including a first surface, in which an opening is formed, the cover being configured to pivot about an axis of a first rotating shaft parallel to the first surface; and a touch panel, which is to be located in the opening when the cover is in a closed state in which the cover covers the housing. The cover includes a frame between an edge of the first surface and the opening.
