Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional X-ray imaging systems face challenges with space occupancy and flexibility in positioning due to fixed supporting arms, which restrict the adjustment of the platform for optimal imaging, especially when dealing with varying patient positions.
Innovation Solution
A platform telescoping mechanism with a first and second supporting arm, a linear driving mechanism, and a rotational driving mechanism, allowing the platform to pivot and move horizontally, enabling two degrees of freedom for precise positioning while minimizing the system's footprint.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the supporting arm is made longer to extend the platform farther from the upright column, then the flexibility in positioning patients for imaging is improved, but the space occupied by the system increases and manipulation becomes more difficult
Solution Approach 1:
The supporting arm is divided into a first supporting arm with fixed length and a second supporting arm with telescopic capability. This segmentation allows the system to have a compact base structure while providing extended reach when needed, resolving the contradiction between compact footprint and positioning flexibility.
Solution Approach 2:
The second supporting arm is designed with telescopic capability driven by a linear driving mechanism, allowing it to dynamically adjust its length. This enables the system to transition between a compact configuration (reducing space occupancy) and an extended configuration (improving positioning flexibility) based on operational needs.
2Area of stationary object
If the supporting arm is made shorter to reduce the system footprint, then the space occupancy is reduced, but the ability to fine-adjust patient position for optimal imaging is compromised
Solution Approach 1:
By dividing the supporting arm into two segments (first fixed arm and second telescopic arm), the system achieves a short effective footprint when the telescopic arm is retracted, while maintaining fine adjustment capability through the controlled extension and rotation of the second arm.
Solution Approach 2:
The system adds rotational freedom to the telescopic second supporting arm, providing two degrees of freedom (linear extension + rotation). This dimensional addition enables fine positioning adjustments in multiple directions without requiring a longer fixed arm, thus maintaining compact footprint while improving adaptability.
3Device complexity
If a fixed-length supporting arm is used, then the system structure is simple, but the platform cannot adjust its position to accommodate different patient positions and imaging requirements
Solution Approach 1:
The system transitions from a static fixed-length arm to a dynamic telescopic arm with rotational capability. The linear driving mechanism and pivot joint enable the platform to adjust its position and orientation, providing adaptability for different imaging scenarios while maintaining relatively simple structural implementation.
Solution Approach 2:
The telescopic supporting arm system serves multiple functions: it provides both radial extension (through telescoping) and angular adjustment (through rotation), enabling the platform to reach various positions and orientations. This multi-functionality replaces what would otherwise require multiple separate mechanisms.
