Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In biplane X-ray diagnostic apparatuses, existing interference control methods require manual intervention to prevent collisions between arms, which is inefficient and can lead to obstacles during operations.
Innovation Solution
An X-ray diagnostic apparatus with automatic retraction and restoration functions, where the control circuitry manages the movement of arms to ensure the first arm can reach a target position without interference by retracting the second arm and then restoring it to its original position, using position detection and interference detection circuitry to facilitate autonomous operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual interference control is used to prevent arm collisions, then safety is improved, but operational efficiency deteriorates due to required manual intervention
Solution Approach 1:
The system automatically detects potential interference between arms and executes retraction operations without manual intervention. The control circuitry monitors arm positions and autonomously manages collision prevention, eliminating the need for operators to manually intervene while maintaining safety standards
Solution Approach 2:
The system continuously monitors the positions of multiple arms and uses this feedback information to automatically determine when retraction is necessary. Based on real-time position data, the control circuitry executes preventive retraction operations before interference occurs, ensuring safety while maintaining operational flow
2Reliability
If the second arm is retracted to prevent interference with the first arm, then collision prevention is improved, but the second arm becomes an obstacle to subsequent operations
Solution Approach 1:
The system performs retraction of the second arm in advance before the first arm reaches a position that would cause interference. By predicting potential interference based on current arm positions and movement trajectories, the system proactively retracts the second arm to prevent collision before it occurs
Solution Approach 2:
The system dynamically adjusts the retraction and restoration operations based on real-time arm positions and operational context. After the first arm completes its movement, the control circuitry automatically restores the second arm to its original position, ensuring the system adapts to changing operational conditions and eliminates obstacles for subsequent operations
3Productivity
If automatic retraction and restoration operations are implemented, then operational efficiency is improved, but device complexity increases
Solution Approach 1:
The control circuitry is designed to perform multiple functions: monitoring arm positions, detecting potential interference, executing retraction operations, and restoring arms to original positions. This multi-functional approach consolidates what could be separate complex systems into a single integrated control unit, improving efficiency while managing complexity
Solution Approach 2:
The system combines the interference detection function and the retraction/restoration control functions into a single integrated control circuitry. By merging these functions, the system reduces the number of separate components and interfaces, thereby improving operational efficiency while keeping the overall device complexity manageable

AI summary
According to one embodiment, an X-ray diagnostic apparatus includes a first apparatus, a second apparatus, movement instruction input circuitry and control circuitry. In accordance with a movement instruction, the control circuitry is configured to control the first and second apparatuses so that the first apparatus can be moved to the target position. The control circuitry is configured to perform a retraction operation and a restoration operation. The retraction operation is an operation in which the first apparatus starts moving toward the target position and continues to move toward the target position, with the second apparatus retracted. The restoration operation is an operation in which the second apparatus is returned to the original position while avoiding the collision with the first apparatus.
