Radiographic Imaging Panel Housing for Grip and Low-Force Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radiographic imaging apparatuses face challenges in providing adequate grip and ease of handling, especially when inserting or removing them between a subject and a contact surface, due to their thickness and design, which can cause discomfort and hinder quick imaging operations.
Innovation Solution
The apparatus is designed with a thin section and a grip portion, allowing for improved grippability and user workability by reducing the step created by the thickness, and incorporating features like sloped portions and recessed grips to facilitate easy insertion and removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the thickness of the radiation detection unit is reduced to improve handleability, then the apparatus becomes thinner and easier to handle, but the user cannot adequately grip the apparatus with fingers
Solution Approach 1:
The housing is divided into a thick section and a thin section, with the grip portion specifically located in the thick section. This segmentation allows the apparatus to have an overall thin profile for ease of handling while providing a localized thick region that accommodates finger grip, resolving the contradiction between thinness and grippability.
Solution Approach 2:
The grip portion is provided with a recessed shape at a specific location (in the thick section) to enhance local grippability. This local modification allows users to adequately grip the apparatus with fingers without increasing the overall thickness of the radiation detection unit, as the recess is confined to a localized area.
2Ease of operation
If a simple grip portion is provided to improve handleability, then the apparatus becomes easier to hold, but the user cannot maintain adequate grip when inserting or removing the apparatus into/from a gap between the subject and the contact surface
Solution Approach 1:
The grip portion is designed with a recessed shape that adapts to dynamic insertion movements. The recessed configuration allows fingers to maintain grip during the dynamic action of inserting or removing the apparatus into narrow gaps, preventing slippage that would occur with a flat surface while preserving overall handleability.
Solution Approach 2:
The grip portion is asymmetrically positioned in the thick section rather than being centrally located or symmetrically distributed. This asymmetric placement optimizes the grip geometry for the specific insertion motion required in radiographic imaging, allowing reliable grip maintenance during the unidirectional insertion and removal actions performed in clinical practice.
3Ease of manufacture
If the apparatus has a uniform thickness to simplify manufacturing, then manufacturing is easier, but a step is created by the thickness that increases reaction forces on the subject during insertion
Solution Approach 1:
The housing is segmented into thick and thin sections, with the thin section forming the primary imaging surface that contacts the subject. This segmentation eliminates the step problem by making the subject-contacting portion thin, thereby reducing reaction forces on the subject during insertion, while the thick section provides structural support and grip functionality.
Solution Approach 2:
The thick section is locally positioned away from the subject-contacting thin section, concentrating the thickness where it provides benefit (structural support and grip) rather than where it causes harm (reaction forces on subject). This local quality differentiation resolves the contradiction between manufacturing simplicity and reduction of harmful reaction forces.

AI summary
A radiographic imaging apparatus includes a radiation detection panel that includes an effective imaging area configured to detect radiation transmitted through a subject and incident on an incident surface, and a housing that accommodates the radiation detection panel. The housing includes a thick section that is thick in a direction normal to the incident surface and located at one end of the housing, and a thin section that is thinner than the thick section and overlaps the effective imaging area at least in part as seen in the direction normal to the incident surface. The thick section includes a grip portion of recessed shape.
