Solution Overview
Problem
Existing biplanar X-ray imaging devices face challenges in accurately aligning rotating axes and limiting the variability of angles between imaging systems, restricting their ability to form biplanar and multi-angle images effectively.
Innovation Solution
A biplanar X-ray imaging device comprising C-shaped arms with sliding and rotating components, where the first C-shaped arm is slidably disposed outside the second C-shaped arm, sharing a common rotating axis, allowing for adjustable angles between imaging devices through controlled movement and rotation, enabling the formation of biplanar and multi-angle images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two imaging systems are installed in a rotatable circular ring orthogonally, then the imaging systems can capture images in two planes, but the angle between the two imaging systems is always 90 degrees and can't be changed
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed angular relationship into a variable one. The two C-shaped arms are connected through a sliding mechanism that allows the arms to move relative to each other, enabling the angle between imaging systems to be adjusted dynamically rather than being fixed at 90 degrees. This resolves the contradiction by making the structure adaptable while maintaining manageable complexity through a well-defined mechanical linkage.
Solution Approach 2:
The patent implements parameter changes by allowing the angle parameter between the two imaging systems to vary. Through the sliding connection between C-shaped arms, the angular parameter can be changed from a fixed 90 degrees to any desired angle within the mechanical limits of the structure. This enables versatile imaging configurations while using a relatively simple mechanical adjustment mechanism.
2Ease of operation
If two imaging systems are installed with different rotating axes, then the imaging systems can be independently positioned, but the alignment accuracy between the two imaging systems deteriorates
Solution Approach 1:
The patent applies segmentation by separating the positioning functions into two independent C-shaped arms that can be adjusted separately. Each arm can be positioned independently to achieve the desired orientation, while the sliding connection between them ensures that both arms share a common rotating axis. This resolves the contradiction by allowing independent positioning operations while maintaining precise axis alignment through the shared mechanical connection.
Solution Approach 2:
The sliding connection between the two C-shaped arms acts as an intermediary mechanism that coordinates their movements. This intermediary ensures that when both arms are positioned independently, they automatically maintain a common rotating axis, thereby preserving alignment accuracy while allowing independent positioning of each imaging system.
3Adaptability or versatility
If the angle between imaging systems is fixed, then the device structure is simple, but the imaging versatility is limited
Solution Approach 1:
The patent uses the dynamics principle to enable angle variability through a sliding and rotating mechanism. The C-shaped arms can slide relative to each other and rotate, allowing the angle between imaging systems to be dynamically adjusted. This provides imaging versatility while keeping the mechanism relatively simple through well-defined mechanical movements rather than complex active control systems.

AI summary
This invention discloses a biplanar X-ray imaging device, comprising the second C-shaped arm and the first C-shaped arm which can be slidably disposed on the second C-shaped arm; the first X-ray generation device and the first image receiving device are disposed on the first C-shaped arm, thus constituting the first imaging device; the second X-ray generation device and the second image receiving device are disposed on the second C-shaped arm, thus constituting the second imaging device; the first C-shaped arm and the second C-shaped arm share the same rotating axis. For the biplanar X-ray imaging device of this invention, when the first C-shaped arm slides along the second C-shaped arm, different angles are formed between the first imaging device and the second imaging device; in addition, the first C-shaped arm and the second C-shaped arm share the same rotating axis, which ensures that the first imaging device and the second imaging device share the same rotating axis.
