Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the detector cartridge moves the detector relative to the table panel to adjust the imaging region, then the adaptability is improved, but the measurement precision of detector position deteriorates
Solution Approach 1:
The patent introduces light transmitting plates and light emitting units as intermediary elements to indicate detector position. The light emitting units are mounted on the detector cartridge and emit light that passes through the light transmitting plates on the table panel, providing a visual indication of the detector's real-time position without interfering with the movement mechanism.
Solution Approach 2:
The patent uses light emitting units that emit light of different colors to indicate different detector positions or states. By changing the color or presence of light, the system provides intuitive visual feedback about detector positioning, allowing operators to quickly assess alignment without complex measurement instruments.
2Adaptability or versatility
If the detector cartridge moves the detector relative to the table panel, then the adaptability is improved, but the alignment accuracy deteriorates
Solution Approach 1:
The light transmitting plates and light emitting units serve as intermediary visual indicators that help operators achieve accurate alignment. The light from the emitting units passes through the transmitting plates to show the exact position of the detector cartridge, enabling precise manual or automated alignment with the X-ray source.
Solution Approach 2:
The patent implements a visual feedback mechanism where the light emitting units continuously indicate detector position through the light transmitting plates. This real-time feedback allows operators to adjust the detector cartridge position to achieve optimal alignment with the X-ray source, ensuring accurate imaging regardless of the selected imaging region.
3Device complexity
If no position indication system is provided, then the device complexity is reduced, but the ease of operation deteriorates
Solution Approach 1:
The patent uses simple light emitting units that emit visible light to indicate detector position. This visual indication system is intuitively understood by operators without requiring complex interfaces or training, significantly improving ease of operation while adding minimal structural complexity.
Solution Approach 2:
The light emitting units are mounted on the detector cartridge itself, making the positioning information self-indicating. The system automatically provides position feedback without requiring external measurement tools or complex operator procedures, allowing operators to easily determine and adjust detector position.
