Solution Overview

Problem

Existing radiography systems do not consider the movement of a radiation source along a decubitus table, leading to instability and difficulty in positioning the radiation source.

Innovation Solution

A radiography system with a radiation source unit that is independently movable and attachable to a decubitus table, featuring a guide mechanism and an attachment portion that supports the weight of the radiation source unit, allowing for stable movement and positioning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If the radiation source unit is fixed to the decubitus table, then stability is improved, but positioning flexibility and ease of movement deteriorate

Engineering Contradiction:

Improvestability of radiation source unitVSAvoidease of movement of radiation source unit

Core Design Contradiction:

Stability of the object's compositionVSEase of operation

Solution Approach 1:

The radiation source unit is designed with a dual-state attachment system that transitions between a fixed stable state and a movable flexible state. The attachment portion allows the unit to be securely fastened to the decubitus table when positioning is complete, while enabling easy detachment and repositioning during the radiography procedure. This dynamic adaptability resolves the contradiction between stability and ease of movement.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If the radiation source unit is made detachable and movable, then positioning flexibility is improved, but stability and weight support deteriorate

Engineering Contradiction:

Improvepositioning flexibility of radiation source unitVSAvoidstability of radiation source unit

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The system is divided into separate components: a detachable radiation source unit and a decubitus table with an integrated attachment mechanism. This segmentation allows the radiation source unit to be independently positioned and attached at optimal locations, providing flexibility while maintaining stability through the dedicated attachment portion that secures the unit to the table structure.

Inventive Principle:

Principle #1Segmentation

3Ease of operation

If the radiation source unit is independently movable, then ease of positioning is improved, but device complexity increases

Engineering Contradiction:

Improveease of positioning of radiation source unitVSAvoidcomplexity of attachment mechanism

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The attachment portion serves multiple functions: it supports the weight of the radiation source unit, provides secure fixation to the decubitus table, and enables easy detachment and repositioning. This multi-functionality reduces the need for separate mechanisms for each function, thereby simplifying the overall device complexity while maintaining ease of positioning.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A radiography system includes a decubitus table and a radiation source unit that is configured to be independently movable from the decubitus table and includes a radiation source. The radiation source unit is capable of being attached to and detached from the decubitus table, and has an attachment portion that supports at least a part of a weight of the radiation source unit in a state in which the radiation source unit is attached to the decubitus table. The decubitus table has a guide mechanism that guides a movement of the radiation source unit attached through the attachment portion.
