Solution Overview

Problem

The existing methods for long-scale radiographic imaging using multiple units are inefficient due to the time and effort required for splicing images when the layout of the units is unknown, leading to difficulties in generating a cohesive image.

Innovation Solution

A radiographing system comprising multiple radiographic imaging units connected via a communication unit, an acquisition unit for path information, and an output unit to generate a long-scale image based on the acquired path information, allowing for simultaneous irradiation and efficient image processing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If multiple radiographic imaging units are used for long-scale imaging, then the imaging coverage area is increased, but the time and effort required for splicing images increases

Engineering Contradiction:
Improveimaging coverage areaVSAvoidtime and effort for splicing
Core Design Contradiction:
Area of stationary objectVSLoss of time

Solution Approach 1:

The system performs preliminary actions by acquiring path information between imaging units before the splicing process. The control apparatus obtains communication path information that indicates the spatial relationships and connections between multiple radiographic imaging units, allowing the splicing to be performed more efficiently by knowing the predetermined layout in advance, thus reducing the time and effort required for image splicing

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If the layout among radiographic imaging units is unknown, then flexibility in unit placement is maintained, but the complexity of splicing processing increases

Engineering Contradiction:
Improveflexibility in unit placementVSAvoidcomplexity of splicing processing
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system introduces an intermediary element - the path information - that mediates between the flexible unit placement and the splicing processing. The control apparatus acquires path information that serves as a bridge, indicating the communication paths and spatial relationships between imaging units. This intermediary information allows the system to maintain flexibility in unit placement while significantly reducing the complexity of splicing processing, as the path information provides the necessary layout data without requiring rigid predetermined positions

Inventive Principle:
Principle #24Intermediary (Mediator)
