Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radiation imaging apparatuses face challenges in providing easy and versatile holding options due to varied usage environments, necessitating improved ergonomic design for better portability and handling.
Innovation Solution
The apparatus features a casing with indented holding portions on the rear surface, including deep and shallow recesses along the perimeter, designed to accommodate various holding methods, enhancing grip and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If uniform holding portions are provided on the rear surface, then the structure is simple, but the ease of holding in various environments is insufficient
Solution Approach 1:
The patent applies local quality by creating holding portions with different indentation depths at different locations on the rear surface. Specifically, holding portions are designed with greater indentation depth at positions closer to the center of each side compared to positions closer to the corners. This variation in local properties allows fingers to engage effectively in multiple holding methods (one-handed grip, two-handed grip, edge holding) while maintaining a relatively simple overall structure.
2Stability of the object's composition
If deep recesses are provided for finger engagement, then the grip stability is improved, but the portability and lightweight design are compromised
Solution Approach 1:
The patent resolves this contradiction by applying local quality through varied indentation depths. Deeper recesses are positioned at the center portions of each side where finger engagement is most effective for stable gripping, while shallower recesses are positioned at the corners. This localized variation provides sufficient grip stability without requiring uniformly deep recesses across the entire surface, thereby minimizing weight increase while maintaining portability.

AI summary
A radiation imaging apparatus includes a radiation detecting panel that detects radiation, and a casing that houses the radiation detecting panel and including a front portion where the radiation is incident on the radiation detecting panel and a rear portion opposite to the front portion, wherein the rear portion includes a holding portion indented toward the front portion, wherein the holding portion includes a predetermined holding region extending along a predetermined side when an outer perimeter of the rear portion is viewed as a quadrilateral shape, and wherein the predetermined holding region has a greater indentation depth at a position closer to a center of the predetermined side than to an end portion of the predetermined side than at a position closer to the end portion than to the center.
