Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing C-arm X-ray imaging systems require cumbersome and unreliable methods to remember and return to specific orbital angular positions, leading to inefficiencies in imaging procedures.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual marking methods (scales or temporary marks) are used to remember C-arm positions, then no additional device is needed, but the process becomes slow, tedious, and unreliable requiring careful hand/eye coordination
Solution Approach 1:
A physical blocking device is introduced as an intermediary between the C-arm rotation mechanism and the operator. This device mechanically prevents the C-arm from rotating beyond a predetermined position, serving as a reliable stop that eliminates the need for manual marking and hand/eye coordination. The blocking device acts as a mediator that translates the abstract concept of a target position into a concrete mechanical constraint.
2Measurement precision
If a blocking device is introduced to prevent over-rotation, then position accuracy is improved, but the device complexity increases
Solution Approach 1:
The blocking device is designed as a segmented, modular component that can be independently positioned and adjusted along the C-arm structure. The device consists of separate elements including a blocking element, positioning mechanism, and mounting components that can be independently manufactured and assembled. This segmentation reduces overall system complexity by allowing each component to be optimized independently and simplifies maintenance and adjustment procedures.
3Adaptability or versatility
If frequent repositioning of the C-arm is required, then multiple imaging angles are achieved, but the imaging procedure becomes time-consuming
Solution Approach 1:
The blocking device is pre-configured with predetermined stop positions that correspond to optimal imaging angles. Before the imaging procedure begins, the device is set to block at specific angular positions, allowing the operator to quickly and accurately reposition the C-arm between shots without needing to calculate or estimate angles. This preliminary setup enables rapid switching between predefined imaging angles, maintaining versatility while improving procedure speed.
