Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radiation shielding devices struggle to effectively protect the thyroid from radiation exposure during medical procedures, particularly when X-ray equipment emits radiation in varying directions, as they fail to adjust their position accordingly, leading to potential harm and increased cancer risk.
Innovation Solution
A radiation shielding device with a shielding unit that reciprocatively moves along a through passage within a body structure, driven by a motor, allowing the shielding pad to change position in response to changes in the radiation direction, thereby minimizing exposure to the thyroid area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a typical shielding device is used, then the structure is simple and easy to manufacture, but it cannot change position when radiation direction changes, leading to inadequate protection
Solution Approach 1:
The shielding device is transformed from a static structure to a dynamic one by introducing a motor-driven driving unit that reciprocates the shielding pad along a guiding passage. This allows the shielding pad to actively adjust its position in response to changing radiation directions, resolving the contradiction between adaptability and structural simplicity.
Solution Approach 2:
The shielding device is designed to perform multiple functions: it can shield radiation when the pad is in the shielding position and allow radiation transmission when moved to the transmission position. This multi-functionality enables a single device to adapt to different operational requirements without needing multiple separate components.
2Reliability
If the shielding pad remains in a fixed position, then the device structure is simple, but the thyroid cannot be protected during serial radiography with changing radiation directions
Solution Approach 1:
The shielding pad is converted from a fixed component to a movable one through the integration of a motor-driven driving unit. This dynamic configuration enables the pad to reciprocate between shielding and transmission positions, ensuring reliable thyroid protection during serial radiography while maintaining reasonable structural complexity.
Solution Approach 2:
The control unit receives signals about radiation direction changes and automatically adjusts the shielding pad position accordingly. This feedback mechanism ensures that the shielding device responds appropriately to changing conditions, maintaining high reliability without requiring complex manual intervention systems.
3Adaptability or versatility
If a movable shielding mechanism is added to track radiation direction, then radiation protection effectiveness improves, but the device complexity increases
Solution Approach 1:
A motor-driven driving unit is introduced to enable dynamic reciprocation of the shielding pad along a guiding passage. This controlled movement mechanism provides the necessary adaptability to track radiation direction changes while maintaining a manageable level of device complexity through structured mechanical design.
Solution Approach 2:
The control unit acts as an intermediary between the radiation source detection and the shielding pad movement. It processes radiation direction information and translates it into appropriate motor control signals, simplifying the overall system architecture by centralizing the control logic in a dedicated intermediary component.
