Mobile X-ray Apparatus Switch Arrangement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile X-ray diagnostic apparatuses require labor-intensive movement between the front and rear sides during imaging, leading to degraded operability due to the placement of operating switches, which changes visual positional relations when the support column turns, making intuitive operation challenging.
Innovation Solution
The apparatus features input equipment with operating switches arranged vertically along the rotation axis of the support column, ensuring their positional relation remains constant regardless of the support column's orientation, enhancing intuitive operation and reducing movement labor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If operating switches are placed on the front side of the apparatus, then the operator can access them during imaging, but the visual positional relation of the switches changes when the support column turns, degrading operability
Solution Approach 1:
The patent applies dimensionality change by arranging operating switches vertically along the rotation axis of the support column instead of horizontally on the front side. This vertical arrangement along the rotation axis ensures that the switches maintain a constant visual positional relation regardless of the support column's orientation, resolving the contradiction between accessibility and operational stability.
2Measurement precision
If the support column is made movable for positioning, then the apparatus can be positioned accurately, but the operator must move between front and rear sides, increasing labor
Solution Approach 1:
The patent resolves the labor issue by moving the operating switches to the vertical dimension along the rotation axis, allowing the operator to access all switches from a single position without moving between front and rear sides. This maintains positioning accuracy while eliminating the need for operator movement.
Solution Approach 2:
The support column structure is designed to serve multiple functions: it provides accurate positioning capability while also serving as the mounting location for operating switches. This multi-functionality allows the same structural element to address both positioning precision and operator convenience.
3Ease of operation
If operating switches are placed on the front side, then they are accessible during imaging, but the visual positional relation changes with support column orientation, making intuitive operation challenging
Solution Approach 1:
The patent simplifies the positioning system by arranging switches vertically along the rotation axis, creating a stable visual reference that does not change with support column orientation. This eliminates the need for complex repositioning mechanisms and provides intuitive operation through consistent spatial relationships.

AI summary
A mobile X-ray-diagnostic apparatus of an embodiment includes an X-ray generator, an arm, a main body, a support column, and at least two input equipment. The X-ray generator generates X-rays. The arm holds the X-ray generator at one end. The main body includes wheels. The support column is turnably supported about a vertical direction as an axis, and supports another end of the arm. The at least two input equipment are arranged on the support column such that heights in the vertical direction differ from each other, and controls driving of the main body.
