Battery Mounting on Upper Surface for Portable Printer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable recording apparatuses, such as printers, face issues with poor operability and increased size due to the need to access batteries from the back, which complicates battery attachment and removal and compromises portability.
Innovation Solution
The battery is mounted on the upper surface of the apparatus body, allowing it to form part of the upper surface when attached, reducing the overall size and improving portability by positioning electronic components efficiently under the battery and using a medium supporting section inclined downward to create space for additional components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the battery is attached on the back side of the apparatus body, then the battery can be accessed for attachment and removal, but the user needs to turn the printer to observe the battery mounting surface, resulting in poor operability
Solution Approach 1:
The battery mounting position is moved from the back side to the upper side of the apparatus body, changing the spatial dimension of access. This allows users to attach and remove batteries without rotating the device, as the upper side is naturally accessible in the upright printing orientation.
2Ease of operation
If the battery is attached on the back side of the apparatus body, then the battery can be mounted, but the overall size of the apparatus is increased on the back side, reducing portability
Solution Approach 1:
The battery is repositioned from the back side to the upper side of the apparatus body. This spatial relocation utilizes the upper surface area that would otherwise be unused, preventing back side protrusion and maintaining a compact overall size suitable for portable applications.
3Volume of moving object
If the battery is attached on the upper surface of the apparatus body, then the overall size is reduced and portability is improved, but the battery must form part of the upper surface which may affect other component placement
Solution Approach 1:
The battery is positioned on the upper surface to minimize overall apparatus volume. The circuit substrate is configured to extend from under the battery toward the recording head, with electronic components arranged to overlap the battery's occupied region in the height direction, efficiently utilizing vertical space and avoiding increased apparatus height.

AI summary
A recording apparatus includes a recording unit that performs recording on a medium which is transported from the side of a second surface which is opposite to a first surface which forms a periphery of an apparatus body to the side of the first surface, a delivery section that delivers the medium on which recording has been performed by the recording head from the side of the first surface, a notch section formed at a corner formed by an upper surface and the second surface of the apparatus body, and a battery which is attached on the notch section and forms part of the upper surface and part of the second surface of the apparatus body in a state that the battery is attached.
