Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing imaging devices, such as C-arms, suffer from distortions that complicate image segmentation and registration due to varying types, sizes, and shapes, necessitating a universal adaptor for easy installation of image correctors.
Innovation Solution
A crane adaptor with a main clamping rod, side clamping rods, adjustable brackets, and belt assemblies with ratchets to securely attach to different types of C-arms, ensuring precise and efficient installation of image correctors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a universal adaptor is designed to fit various C-arm configurations, then adaptability is improved, but device complexity increases
Solution Approach 1:
The adaptor is designed with multiple clamping mechanisms including a first clamping mechanism with a first clamping rod and first clamping arm, a second clamping mechanism with a second clamping rod and second clamping arm, and a third clamping mechanism with a third clamping rod and third clamping arm. Each mechanism can independently secure to different parts of the C-arm structure, enabling the single adaptor to accommodate various C-arm configurations and sizes through multiple attachment points
Solution Approach 2:
The adaptor structure is divided into separate modular components including individual clamping rods, clamping arms, and linkage mechanisms that can be independently adjusted. This segmentation allows each component to be optimized for specific functions while maintaining overall adaptability, reducing the complexity burden by making the system composable rather than monolithic
2Reliability
If multiple clamping mechanisms are added to secure different C-arm types, then reliability is improved, but ease of operation deteriorates
Solution Approach 1:
The first clamping mechanism, second clamping mechanism, and third clamping mechanism are integrated into a single adaptor assembly that attaches to the image corrector. This merging allows all clamping actions to be coordinated through a unified structure, reducing the operational steps required compared to installing separate attachment devices for each C-arm component
Solution Approach 2:
The adaptor incorporates linkage mechanisms connecting the clamping arms to the clamping rods, allowing dynamic adjustment and coordinated movement of multiple clamping points. This dynamic design enables operators to secure the adaptor to irregular C-arm structures through sequential adjustment of linked components rather than requiring precise simultaneous positioning of multiple independent fasteners
