Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing X-ray inspection apparatuses are expensive due to the use of leaded glass or acrylic resin plates for shielding, and there is a demand for a cost-effective solution that allows viewing the inside of the housing without using such materials.
Innovation Solution
An X-ray inspection apparatus with a window and a shielding plate configured from multiple plate-form members disposed at predetermined spacings, allowing viewing through gaps while preventing X-ray leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If leaded glass or acrylic resin plate is used to seal the window for X-ray shielding, then X-ray leakage is prevented, but the apparatus becomes expensive
Solution Approach 1:
The shielding plate is divided into multiple plate-form members (first, second, third plate-form members) arranged at predetermined spacings. Each plate-form member is a separate component that collectively provides X-ray shielding when positioned together, replacing the need for a single continuous leaded glass or resin plate.
Solution Approach 2:
The plate-form members act as intermediary shielding elements positioned between the X-ray source and the external environment. These members intercept scattered X-rays through their strategic positioning and orientation, providing shielding functionality without requiring traditional expensive materials.
2Ease of operation
If the window is opened for viewing the inside of the housing, then observation is enabled, but X-rays can leak to the outside
Solution Approach 1:
The shielding solution provides localized protection at specific positions where scattered X-rays are most likely to escape through the window. The plate-form members are positioned and oriented to create shielding zones at critical locations while maintaining gaps for viewing, rather than providing uniform shielding across the entire window area.
Solution Approach 2:
The plate-form members are oriented at specific angles and positioned in three-dimensional space to intercept X-rays traveling in various directions. By utilizing spatial arrangement and angular orientation, the solution creates effective shielding paths while maintaining line-of-sight viewing capability through the gaps between members.
3Area of stationary object
If plate-form members are disposed at predetermined spacing to allow viewing, then field of view is improved, but X-ray shielding effectiveness may be compromised
Solution Approach 1:
The shielding system utilizes the dynamic positioning and angular orientation of multiple plate-form members to adaptively shield against scattered X-rays while maintaining viewing capability. The predetermined spacing and orientation create an optimal balance between field of view and shielding effectiveness for the specific application conditions.

Implementation Method 1
an X-ray shielding plate that shields against the X-rays that leak out through the window of the housing, the plate-form members being disposed at a predetermined spacing on an inner side of the window at positions where X-rays leaking through the window are shielded against

AI summary
In an inspection apparatus that irradiates articles with X-rays and inspects for cracking and chipping of the articles, a side surface of a housing in which X-rays for inspection are scattered is provided with a window through which an interior can be visually confirmed, and an inner side of the window is provided with an X-ray shielding member that shields against X-rays but allows the inside of the housing to be seen. The shielding member is configured from a plurality of plate-form members, and the plate-form members are disposed at a predetermined spacing on the inner side of the window at positions where X-rays leaking from the window are shielded against.
