Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the detector slit dimension is fixed, then the imaging apparatus structure is simple, but it cannot adapt to varying patient sizes and examination requirements
Solution Approach 1:
The detector slit dimension is made variable through a setting device that can adjust the slit width along the displacement axis. This dynamic adjustment allows the imaging apparatus to adapt to different patient sizes and examination requirements without fundamentally changing the overall system structure, resolving the contradiction between adaptability and structural simplicity.
2Measurement precision
If the detector slit dimension is adjusted to match patient size, then image resolution and radiation utilization are optimized, but the device complexity increases
Solution Approach 1:
The invention changes the physical parameter of the detector slit dimension to optimize image resolution and radiation utilization for different patient sizes. The setting device modifies the slit width parameter dynamically, allowing the system to achieve optimal imaging performance without requiring complex fundamental redesigns, thus balancing precision improvement with acceptable device complexity.
3Loss of energy
If a fixed detector slit is used, then the device is easier to operate, but radiation is not efficiently utilized
Solution Approach 1:
The detector slit dimension is made dynamically adjustable through the setting device, allowing optimization of radiation utilization efficiency for different patient sizes and examination types. While this introduces some operational complexity, the system maintains ease of use by providing a straightforward adjustment mechanism that can be configured based on specific imaging requirements, balancing radiation efficiency with operational simplicity.
