Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If high voltage is rapidly applied to anode electrode to achieve high output power, then productivity is improved, but temperature increases causing overheating and vacuum destruction
Solution Approach 1:
A cooling unit is introduced as an intermediary component between the anode electrode and the environment. This cooling unit acts as a heat sink that absorbs and dissipates the heat generated at the anode electrode, allowing high voltage to be applied for high output power while preventing overheating through active thermal management.
Solution Approach 2:
The cooling unit is designed to remove heat generated at the anode electrode before the temperature reaches critical levels that would cause vacuum destruction. By continuously or periodically activating the cooling mechanism in advance, the system maintains safe operating temperatures even during high-power operation.
2Productivity
If high voltage is applied to increase X-ray emission, then productivity is improved, but object-generated harmful factors increase due to excessive radiation discharge
Solution Approach 1:
The shielding unit, positioned between the X-ray generation area and the external environment, converts the harmful radiation into a contained phenomenon. By strategically placing shielding materials, the system allows useful X-ray emission for imaging while blocking harmful radiation from reaching technicians and surrounding areas, effectively managing radiation exposure.
3Ease of operation
If insulation columns are provided to adjust electrode positions, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The electrode positioning system is segmented into modular insulation columns that can be independently adjusted. Each insulation column serves as a discrete unit for positioning specific electrodes, allowing flexible adjustment of electrode positions while maintaining a relatively simple overall structure. The segmented design enables ease of operation without requiring complex integrated positioning mechanisms.
