Recording Apparatus Cassette Protrusion Nesting in Support Column
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing recording apparatus designs that include protruding portions on medium cassettes to prevent them from coming off increase the size of the apparatus, making it difficult to reduce the overall dimensions and accommodate other components.
Innovation Solution
The design incorporates a medium cassette with a protruding portion that protrudes in the direction of housing, and an accommodating portion formed in the support column to house this protrusion, allowing the apparatus to maintain compactness without increasing size, with optional features like bent or reinforced support columns and integrated metal frames for cost-effectiveness and structural integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a protruding portion is provided on the medium cassette to prevent it from coming off, then the reliability of the medium cassette is improved, but the size of the apparatus body increases
Solution Approach 1:
The protruding portion of the medium cassette is nested within the support column structure. The support column has a hollow interior space that accommodates the protruding portion, allowing the cassette to be retained without increasing the external dimensions of the apparatus body.
Solution Approach 2:
Instead of extending the protruding portion in the width direction or depth direction which would increase apparatus size, the solution utilizes the height direction by creating a vertical accommodation space within the support column, thereby resolving the contradiction through dimensional repositioning.
2Volume of stationary object
If the protruding portion is positioned to overlap with the support column, then the apparatus size is reduced, but the space between support columns is occupied making it difficult to arrange other components
Solution Approach 1:
The support column is segmented into functional zones: the upper portion maintains structural support function while the lower portion contains the accommodation space for the protruding portion. This segmentation allows the space between support columns to remain available for other components while still achieving compact dimensions.
Solution Approach 2:
The support column is designed with non-uniform properties: it has structural integrity in the width direction while containing a localized hollow space in the depth direction. This local quality differentiation allows the column to fulfill multiple functions without compromising overall structure or component arrangement flexibility.

AI summary
A recording apparatus includes an apparatus body that includes a recording unit that performs recording on a medium, a medium cassette configured to slide in a first direction, and a second direction, a frame forming a plane that is along a lateral face of the apparatus body, and a support column portion located at an end of the frame in an apparatus width direction intersecting with the slide directions of the medium cassette and extending in a height direction of the apparatus body. The frame forms the plane that is along the lateral face of the apparatus body at a second direction side. The medium cassette has, at an end in the second direction, a protruding portion that protrudes in the second direction. An accommodating portion configured to accommodate the protruding portion is formed in the support column portion.
