Radiation Imaging Casing Recesses for Ergonomic Lifting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable radiation imaging apparatuses face challenges in comfortable holding and easy lifting, particularly when the incident surface is laid flat, due to the placement and removal of batteries, which can make them difficult to handle and transport.
Innovation Solution
The design incorporates a casing with a first recessed portion on one side surface and a second recessed portion on the back surface, allowing for easier gripping and lifting by forming ergonomic recesses that facilitate stable portability and operation, even when the apparatus is placed on a flat surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the imaging apparatus is designed to be portable and compact, then it becomes easier to transport and store, but it becomes more difficult to hold stably and lift easily when placed on a flat surface
Solution Approach 1:
The patent applies local quality by creating recessed portions at specific locations on the housing rather than uniformly modifying the entire structure. The first recessed portion is formed in one side surface and the second recessed portion is formed in the back surface at a position opposite to the first recessed portion, allowing ergonomic gripping only where needed while maintaining the overall compact form factor of the imaging apparatus.
Solution Approach 2:
The patent employs asymmetry by positioning the first and second recessed portions at specific asymmetric locations on the housing. The recessed portions are arranged to be opposite each other with respect to a boundary between the back surface and side surface, creating an asymmetric grip pattern that facilitates easy lifting from either side while maintaining a compact rectangular parallelepiped overall shape.
2Volume of moving object
If the imaging apparatus is made compact for portability, then it is easier to transport, but the battery replacement operation becomes difficult when the incident surface is laid on a flat surface
Solution Approach 1:
The patent applies local quality by creating recessed portions at specific locations on the housing rather than uniformly modifying the entire structure. The first recessed portion is formed in one side surface and the second recessed portion is formed in the back surface at a position opposite to the first recessed portion, allowing ergonomic gripping only where needed while maintaining the overall compact form factor of the imaging apparatus.
Solution Approach 2:
The patent employs preliminary action by pre-forming recessed portions in the housing structure before battery installation. These recessed portions are positioned to facilitate easy gripping and lifting of the apparatus when it is placed on a flat surface, enabling users to easily access and replace the battery without difficulty even in compact configurations.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design enables smooth operation and stable lifting of the imaging apparatus, enhancing user comfort and portability by providing defined areas for gripping and lifting, thus addressing the challenges of handling and transporting the device.
Implementation Method 1
a radiation detector arranged to convert a radiation transmitted through an object into an electrical signal

AI summary
In a radiation imaging apparatus, a first recessed portion is formed in at least one side surface among a plurality of side surfaces forming a frame body of a casing. Moreover, a second recessed portion is formed in a peripheral region of a back surface of a back-surface housing, which is a region opposite to the first recessed portion with respect to a boundary between the back surface and the at least one side surface of the casing including the first recessed portion.
