Radiation Imaging Apparatus Concave Grip Portion Design
Solution Overview
Problem
Existing radiation imaging apparatuses face a trade-off between portability and gripping performance, where sufficient portability compromises gripping efficiency, and enhanced gripping performance often results in larger size and reduced portability.
Innovation Solution
A compact radiation imaging apparatus with a cuboid housing featuring concave grip portions on the back surface, ensuring a depth of at least half the distance between the front and back surfaces and centered on the apparatus' gravity, allowing for stable gripping and reduced size.

Engineering Contradiction Analysis
1Ease of operation
If a grip portion with opening is arranged outside the imaging region, then gripping performance is sufficient and portability is improved, but the size of the imaging apparatus cannot be sufficiently reduced
Solution Approach 1:
The grip portion is formed by creating a concave region on the back surface of the housing, utilizing the depth dimension (thickness direction) of the apparatus. This allows the grip portion to be formed within the existing volume without adding external protrusions, thereby improving gripping performance while maintaining compact size.
Solution Approach 2:
The concave grip portion is specifically positioned in the peripheral region of the back surface, creating a localized structural modification. This local quality change provides enhanced gripping capability at the perimeter while the central imaging region remains intact and compact.
2Volume of moving object
If a nonslip portion made of concave portion is formed on the back surface, then the gap between imaging region and outer shape is reduced facilitating downsizing, but gripping performance may not be sufficient
Solution Approach 1:
The grip portion's depth parameter is specifically controlled to be at least one-half of the distance between front and back surfaces, or at least the distance from back surface to center of gravity. This parameter optimization ensures sufficient gripping leverage and holding force while maintaining the compact form factor.
Solution Approach 2:
The grip portion is positioned and sized to balance the center of gravity, creating a stable holding position. By making the depth at least equal to the distance from the back surface to the center of gravity, the apparatus achieves optimal balance and stability when gripped, preventing accidental drops.
3Ease of operation
If grip depth is increased to improve gripping performance, then holding force increases, but the apparatus size increases
Solution Approach 1:
The grip portion depth is set to at least one-half of the total thickness or at least the distance to the center of gravity, which is sufficient to provide adequate holding force without requiring the full thickness. This partial depth is optimal for gripping functionality while preserving overall apparatus compactness.

AI summary
A radiation imaging apparatus is provided. The apparatus includes a radiation detection panel, a housing of a cuboid shape that accommodates the radiation detection panel. The housing has a front surface that the radiation enters, a rectangular back surface arranged on a side opposite to a side of the front surface, and four side surfaces configured to connect the front surface and the back surface. The apparatus further includes a grip portion which is concave toward the radiation detection panel, formed in a peripheral region on the back surface. The grip portion has at least one of a depth not less than one-half a distance between the front surface and the back surface, and a depth not less than a distance between the back surface and a center of gravity of the radiation imaging apparatus.
