Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing three-dimensional digital radiography (DR) systems are not portable, making it inconvenient for medical diagnosis and archaeological imaging, especially in situations where patients or relics cannot be moved.
Innovation Solution
A portable three-dimensional DR system is designed with a support mechanism that includes a telescopic support pole and tube, allowing the X-ray generator to be detachably mounted and easily moved, along with a flat panel detector on a stand, enhancing mobility and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the three-dimensional DR device is made fixed and stable for imaging, then the imaging quality is improved, but the portability and mobility are worsened
Solution Approach 1:
The three-dimensional DR device is divided into separable components: the imaging system (X-ray generator and detector) can be detached from the support stand. This allows the imaging system to be transported separately while the stand remains stationary, resolving the contradiction between stable imaging setup and portability.
Solution Approach 2:
The support pole is designed with telescopic capability, allowing it to extend during imaging operations to provide stable support for the detector, and retract during transport to minimize space occupation. This dynamic adjustment resolves the contradiction between stability during use and portability during transport.
2Stability of the object's composition
If the support structure is made rigid and stable for imaging, then the imaging stability is improved, but the space occupation and storage difficulty are worsened
Solution Approach 1:
The telescopic support pole employs a nested structure where segments of the pole are stored within each other during transport, significantly reducing the volume occupied by the support structure. During imaging operations, the pole extends to provide the necessary stability, thus resolving the contradiction between imaging stability and storage compactness.
3Reliability
If the X-ray generator is permanently mounted for stable operation, then the operational reliability is improved, but the ease of transport and setup are worsened
Solution Approach 1:
The X-ray generator is designed as a detachable component that can be separated from the support pole and stand. This segmentation allows the generator to be transported independently in a protective case, while the support structure remains stationary during imaging operations, resolving the contradiction between operational reliability and ease of transport.
