CT Radiation Source Pulling Assembly for Detector Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In static computer tomography devices, the radiation source mechanism obstructs direct access to the detector mechanism, requiring removal and reinstallation, which is cumbersome due to the large size and weight of the radiation source mechanism.
Innovation Solution
A radiation source mechanism with a pulling assembly and a first support assembly allows for easy movement and positioning, enabling the detector mechanism to be installed, repaired, or replaced without the need for a lifting device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the radiation source mechanism is made large and heavy to ensure stability and shielding, then the shielding performance and stability are improved, but the ease of movement and maintenance access deteriorate
Solution Approach 1:
The radiation source mechanism is designed with dynamic movement capability, allowing it to rotate between a closed position (for shielding during operation) and an open position (for maintenance access). The pulling assembly enables this dynamic transition, resolving the contradiction by making the system adaptable rather than static.
Solution Approach 2:
The radiation source mechanism is segmented into movable and stationary components. The pulling assembly separates the heavy radiation source body from the fixed mounting structure, allowing the radiation source to be moved independently for maintenance while the mounting structure remains stationary, thus enabling ease of movement without compromising overall system stability.
2Stability of the object's composition
If the radiation source mechanism is made large and heavy to ensure stability, then the stability is improved, but the ease of repair and replacement of detector mechanism deteriorates
Solution Approach 1:
The radiation source mechanism can dynamically switch between a stable closed position during operation and an open position for maintenance. The pulling assembly enables this dynamic reconfiguration, allowing the heavy radiation source to be moved out of the way without requiring disassembly of the entire system, thus improving ease of repair while maintaining operational stability.
Solution Approach 2:
The pulling assembly extracts the radiation source mechanism from its fixed position, allowing it to be taken out of the operational configuration and moved to a maintenance configuration. This extraction enables direct access to the detector mechanism without requiring removal of the entire radiation source assembly, facilitating easier repair and replacement.
3Ease of operation
If lifting devices are used to move the radiation source mechanism, then the movement capability is improved, but the device complexity and operational complexity increase
Solution Approach 1:
The radiation source mechanism is designed to be self-servicing through the pulling assembly, which enables manual movement without requiring external lifting devices. The pulling assembly acts as a built-in movement mechanism, eliminating the need for separate lifting equipment and reducing overall system complexity.
Solution Approach 2:
The pulling assembly serves as an intermediary mechanism between the heavy radiation source and the operators. Instead of requiring direct manual handling of the heavy source or complex lifting equipment, the pulling assembly mediates the movement process, providing mechanical advantage and enabling controlled movement with minimal effort.
4Manufacturing precision
If multiple people are required to reset the radiation source mechanism, then the positioning accuracy is improved, but the operational efficiency and time consumption worsen
Solution Approach 1:
The pulling assembly enables single-operator control of the radiation source mechanism movement and positioning. The mechanical design provides inherent positioning features and control mechanisms that allow one person to accurately position the heavy radiation source without requiring multiple people, thus improving operational efficiency while maintaining positioning accuracy.

AI summary
A radiation source mechanism is provided, including: a body (22) for outputting rays; a pulling assembly (21) for limiting a position of the body (22) relative to a machine frame (1) and allow the body (22) to rotate about a first axis of the pulling assembly (21) between a closed position close to the machine frame (1) and an open position away from the machine frame (1); and a first support assembly (23) installed at a lower end of the body (22) to support the lower end of the body (22) to smoothly rotate around the first axis relative to a first working surface below the first support assembly (23). A part of the first support assembly (23) has a disengagement state of being disengaged from the first working surface, and a contact state of being in contact with the first working surface in a process of the body (22) disengaging from the closed position, so as to adjust a contact area between the first support assembly (23) and the first working surface. A computer tomography device is further provided, including a machine frame (1), a detector mechanism (3) and a radiation source mechanism (2), the radiation source mechanism (2) is movable between a closed position of shielding the detector mechanism (3) and an open position of exposing the detector mechanism (3).
