Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a single plane system is used, then installation area and cost are reduced, but operability becomes cumbersome due to manual C-arm movement requirements
Solution Approach 1:
The patent replaces manual mechanical operation with an automated control system. The control unit receives instructions from the operating unit and automatically controls the support mechanism to move the C-arm to predetermined positions, substituting the mechanical manual operation with an automated control system that integrates image data acquisition and C-arm positioning.
2Device complexity
If manual operation is used to change C-arm position, then device complexity remains low, but time consumption increases due to cumbersome operations
Solution Approach 1:
The patent implements preliminary action by pre-storing multiple pieces of image data acquired at different predetermined C-arm positions in the image data storage unit. The control unit automatically retrieves and displays the appropriate pre-acquired image data when the C-arm is positioned, eliminating the time-consuming manual operations of moving the C-arm and acquiring images sequentially.
3Ease of operation
If automated control is implemented, then operability improves with hands-free operation, but device complexity increases due to additional control mechanisms
Solution Approach 1:
The control unit serves multiple functions: it controls the support mechanism to move the C-arm to predetermined positions, manages the acquisition and storage of image data at different positions, and displays the appropriate image data based on C-arm position. This multi-functionality reduces the need for separate dedicated components for each function.
Solution Approach 2:
The operating unit acts as an intermediary between the operator and the automated system. It receives simple user instructions and translates them into automated control commands for the control unit, which then coordinates the support mechanism and image data management, simplifying the user interface while maintaining automated functionality.
