X-ray Tube Collision Prevention via Sensor Feedback Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing X-ray imaging systems face a significant risk of collision during movement, which can occur with operators, other apparatuses, or devices in the scanning room, due to the lack of effective collision prevention methods.
Innovation Solution
The X-ray imaging system incorporates a tube device equipped with one or multiple sensors, such as millimeter wave radar sensors, and a controller with a determination module and a control module. The sensors acquire feedback signals within a preset sensing region, and the controller determines the presence of obstacles and their position, subsequently controlling the motion of the tube device to prevent collisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the tube device moves to a preset position to emit X-ray, then the imaging function is achieved, but collision with operators or other apparatuses may occur
Solution Approach 1:
The sensor detects obstacles in advance before the tube device moves to its preset position. The determination module pre-assesses the movement path for obstacles, and the control module prevents movement if obstacles are detected, performing the collision prevention action before the actual imaging movement occurs.
Solution Approach 2:
A sensor is introduced as an intermediary component between the tube device and the environment. The sensor detects obstacles and provides feedback signals to the controller, which then mediates the movement decision of the tube device, preventing direct collision without requiring complex modifications to the tube device itself.
2Measurement precision
If sensors are mounted on the tube device to detect obstacles, then collision detection capability is improved, but the device structure becomes more complex
Solution Approach 1:
The sensor serves multiple functions: it detects obstacles in the movement path, determines their position relative to the tube device, and provides feedback for both safety prevention and potential navigation purposes. This multi-functionality justifies the addition of the sensor component.
Solution Approach 2:
The sensor provides continuous feedback signals to the controller about obstacles in the sensing region. The determination module processes this feedback to determine obstacle presence and position, creating a closed-loop feedback system that improves detection reliability without requiring overly complex hardware.
3Reliability
If the controller determines obstacle position and controls tube device motion, then collision prevention effectiveness is improved, but the control system complexity increases
Solution Approach 1:
The control system is segmented into distinct functional modules: the determination module handles obstacle detection and position calculation, while the control module handles motion control decisions. This segmentation allows each module to focus on a specific task, simplifying the overall control logic despite the increased system capability.
