Radiographing Apparatus Casing Level-Difference Protection

Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing radiographing apparatuses lack sufficient protection for the casing during handling, as level-difference indicators can get caught on surfaces, potentially damaging the device during alignment.

Innovation Solution

The radiographing apparatus incorporates level-difference portions on the side surface to indicate the effective image-acquisition area, with a protruding sliding portion that reduces external impact by preventing direct contact with surfaces during handling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If level-difference portions are provided on the side surface of the casing to indicate the effective image-acquisition area, then tactile recognition of the image-acquisition area is improved, but the casing becomes vulnerable to damage during handling as the level-difference portions can get caught on surfaces

Engineering Contradiction:

Improvetactile recognition of image-acquisition areaVSAvoiddamage to casing during handling

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The side surface of the casing is segmented into multiple portions with different levels. The level-difference portion is separated from the outer surface by introducing a recess, creating distinct functional zones: the indicator portion (level-difference) and the protective outer surface.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The level-difference portion is nested within the casing structure by forming a recess that accommodates it. This allows the indicator to be embedded within the overall casing form, protecting it while maintaining its指示 function.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Ease of operation

If the level-difference portion protrudes outward to provide clear tactile indication, then the indication function is improved, but the risk of the portion getting caught on surfaces during alignment increases

Engineering Contradiction:

Improvetactile indication clarityVSAvoidprotection against damage during alignment

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

Different portions of the casing have different local qualities: the level-difference portion has a different height to provide tactile indication, while the outer surface maintains a flush, protective quality. This localized differentiation allows each portion to fulfill its specific function optimally.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The recess structure preliminarily protects the level-difference portion by creating a protective barrier before any potential contact with external surfaces occurs during handling or alignment operations.

Inventive Principle:

Principle #9Preliminary anti-action

AI summary

A radiographing apparatus includes a radiation detection panel including an effective image-acquisition area configured to detect radiation and a casing configured to house the radiation detection panel. The casing includes an incidence surface on which the radiation is incident, a back surface opposite the incidence surface, and a side surface between the incidence surface and the back surface. On the side surface of the casing, a level-difference portion indicating a position based on the effective image-acquisition area and a protrusion protruding more outward than the level-difference portion are provided.
