Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple X-ray devices are mounted on a G-stand to provide simultaneous frontal and lateral views, then the surgeon's view is doubled and positioning accuracy is improved, but the system complexity and cable connections increase
Solution Approach 1:
The patent combines multiple X-ray devices (first and second X-ray devices) onto a single G-stand structure, merging their mechanical support and control systems. This integration reduces the need for separate mounting structures and simplifies overall system configuration while maintaining the ability to provide simultaneous frontal and lateral views for improved positioning accuracy.
2Ease of operation
If the G-stand is made rotatable and tiltable for better access and views, then the surgical accessibility is improved, but the device complexity and weight increase
Solution Approach 1:
The patent implements dynamic capabilities in the G-stand by making it rotatable about a horizontal axis perpendicular to the axes of both X-ray devices and tiltable to various angles. This dynamic design allows the system to adapt its configuration during surgery for better access and views, improving ease of operation while the integrated design helps manage the weight increase through efficient structural arrangement.
3Productivity
If voltage calibration is performed manually to determine optimal kV settings, then the scan efficiency is improved, but the time required for calibration increases
Solution Approach 1:
The patent incorporates a feedback mechanism where the system measures the actual voltage output from the X-ray devices and compares it to the desired kV settings. Based on this feedback, the system automatically adjusts the voltage calibration to achieve optimal scan efficiency, eliminating the need for time-consuming manual calibration procedures while maintaining high productivity.
4Reliability
If numerous cables are used to connect X-ray devices to control units, then the system functionality is complete, but the mobility is decreased and tripping risks increase
Solution Approach 1:
The patent merges multiple cable connections into a more integrated wiring system where the first and second X-ray devices share common control pathways and power supplies through the G-stand structure. This consolidation reduces the number of separate cables needed to connect to external control units, thereby improving mobility and reducing tripping hazards while maintaining complete system functionality.
