Digital X-ray Imaging Device with Integrated Cassette Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional computed radiography devices require frequent attachment and detachment of the image plate cassette, leading to mechanical abrasion and limiting mobility due to the need for additional space for image transfer.
Innovation Solution
A compact digital X-ray image capturing device with a built-in image plate and an image plate transfer device that uses a slide or up-mounting type cassette, eliminating the need for cassette detachment by integrating a scan drum with fastening and locking mechanisms for continuous imaging and reduced space occupation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the cassette is detached to scan the image plate, then the image can be scanned, but frequent attachment and detachment cause mechanical abrasion and reduce productivity
Solution Approach 1:
The patent combines the cassette and scanner into a single integrated device, eliminating the need for separate handling of these components. The image plate transfer device is built into the scanner housing, allowing the cassette to remain attached during the scanning process, thus preventing mechanical wear from repeated attachment and detachment while maintaining continuous imaging capability
Solution Approach 2:
The image plate transfer device performs preliminary action by automatically transferring the image plate from the cassette to the scanning position within the integrated device. This automated transfer mechanism eliminates manual handling and ensures the image plate is ready for scanning without requiring cassette detachment, thereby improving both reliability and productivity
2Ease of operation
If sufficient space is provided to transfer the image plate to the scanner, then the image plate can be transferred, but the volume of the device increases and mobility is reduced
Solution Approach 1:
The patent applies nesting by placing the image plate transfer device inside the scanner housing. The transfer mechanism operates within the internal space of the scanner, with the cassette positioned to allow automatic transfer of the image plate to the scanning position without requiring external space. This nested configuration maintains image plate transfer capability while minimizing device volume and preserving mobility
