Printer Cover Handle Layout for Easier Closing Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing printing apparatuses have a design where the open-close cover requires users to extend their hand above and turn it around the handle, making the closing operation cumbersome and inefficient.
Innovation Solution
The printing apparatus features an open-close cover that rotates upward with one end as a fulcrum and includes both an outer-side and inner-side handle, allowing for easier opening and closing by reducing the need to turn the hand around the cover.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the open-close cover is designed with a single outer handle, then the structure is simple, but the closing operation becomes cumbersome requiring users to extend hand above and turn around the handle
Solution Approach 1:
The handle structure is segmented into two distinct handles: an outer handle for opening the cover and an inner handle for closing the cover. This segmentation allows each handle to be optimized for its specific function, eliminating the need to turn around a single handle while maintaining structural simplicity through functional division.
2Ease of operation
If the inner-side handle is positioned at the inner side of the open-close cover, then the closing operation becomes easier without turning hand around, but the handle placement becomes more complex
Solution Approach 1:
Instead of having a single handle that requires the user to turn around, the invention inverts the approach by providing two handles positioned at different locations. The inner handle is positioned at the inner side of the cover, allowing users to naturally close the cover by pushing the inner handle without any awkward hand movements, thus solving the operational difficulty through inverted positioning logic.

AI summary
A printing apparatus includes a head configured to perform printing on a medium and an outer packaging configured to accommodate the head, in which the outer packaging includes an open-close cover that constitutes a portion of an upper surface of the outer packaging, and the open-close cover is configured so as to be able to rotate upward with an one end side being a fulcrum, and include an inner-side handle provided at an inner side of the open-close cover.
