Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing three-dimensional digital radiography (DR) systems are not portable, making it inconvenient for medical professionals to diagnose and treat patients in remote or disaster areas, and for archaeologists to scan immovable relics.
Innovation Solution
A portable three-dimensional DR system is designed, comprising a support mechanism with a telescopic support pole and tube, an X-ray generator that can rotate and move, and a flat panel detector on a stand, allowing for easy setup and disassembly for transportation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the three-dimensional DR device is made fixed and stable for scanning imaging, then the imaging quality and stability are improved, but the portability and ease of transportation deteriorate
Solution Approach 1:
The three-dimensional DR device is divided into separate modules: an X-ray generator module that can rotate and a detector module on an independent stand. This segmentation allows each module to be optimized for its function while enabling easy assembly and disassembly for transportation, resolving the contradiction between imaging stability and portability.
Solution Approach 2:
The X-ray generator is mounted on a rotatable support pole with transmission and drive components, enabling dynamic rotation around the scanned object. This dynamic capability allows the system to maintain stable imaging positions during operation while being portable when disassembled, as the rotation mechanism can be folded or reconfigured for transport.
2Ease of operation
If the three-dimensional DR device is made portable for mobile diagnosis, then the ease of operation and accessibility are improved, but the imaging stability and precision deteriorate
Solution Approach 1:
The rotatable X-ray generator on a support pole provides dynamic positioning capability, allowing the system to be set up in various locations for mobile diagnosis while maintaining precise imaging geometry through controlled rotation and stable mounting during the scanning process.
Solution Approach 2:
The portable three-dimensional DR device can be deployed in multiple settings (remote areas, disaster zones, archaeological sites) while maintaining imaging precision through its standardized design that ensures proper geometric relationships between the X-ray source, object, and detector regardless of location.
3Volume of moving object
If the support structure is made telescopic for compact storage, then the volume for storage is reduced, but the structural complexity increases
Solution Approach 1:
The support pole uses a telescopic structure where inner tubes nest within outer tubes, allowing the support structure to be compacted to a small volume for storage and transportation while maintaining full extension length for operation. This nesting approach manages complexity through standardized telescopic mechanisms.
