A sample loading device and electrostatic levitation apparatus with a cylindrical sample storage part, loading bar, and transfer bars that allow for sequential sample loading and levitation, along with various tips for different tests, such as needle tips for inducing meta-stable crystal phases and quick cooling tips, enable precise control over sample positioning and testing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single sample loading mechanism is used, then the device structure is simple, but the ability to perform various tests on multiple samples efficiently is reduced
Solution Approach 1:
The loading tip is designed with multiple functional capabilities: it can load samples onto the sample holder, position samples precisely using the sample transfer vertical through-hole, and perform various tests including inducing meta-stable crystal phases with needle tips and quick cooling with cooling tips. This multi-functional design allows one component to replace multiple specialized devices, increasing versatility while managing complexity
Solution Approach 2:
The loading tip is segmented into different functional regions: the needle tip portion for inducing crystal phases, the main body for sample transfer, and the cooling tip portion for quick cooling. These segmented functions can be selectively used depending on the test requirements, allowing the device to handle multiple test types with a single integrated component
2Measurement precision
If precise sample positioning control is implemented, then testing accuracy is improved, but the complexity of controlling electric field and sample positioning increases
Solution Approach 1:
The sample transfer vertical through-hole acts as an intermediary mechanism that simplifies precise positioning. Instead of complex multi-axis positioning systems, the through-hole provides a predefined, accurate pathway for sample transfer from the loading bar to the sample holder. This intermediary structure inherently guides sample placement with high precision while avoiding the need for complex active control systems
Solution Approach 2:
The sample transfer vertical through-hole is pre-formed in the loading tip at a specific position and orientation. This preliminary structural preparation ensures that when sample transfer occurs, the sample is automatically positioned with high accuracy without requiring complex real-time control adjustments during the transfer process

AI summary
Sample loading device and electrostatic levitation apparatus. The electrostatic levitation apparatus includes a sample storage part including a rod-shaped sample standby part having an external diameter of a first diameter and a rod-shaped sample loading part having an external diameter of a second diameter and a sample cover part covering the sample standby part. The sample storage part has a loading bar inserting hole formed in its center. The loading bar inserting hole is formed through the sample standby part and is formed successively through a portion of the sample loading part. The sample standby part has sample storage vertical through-holes. The sample loading part has a single sample transfer vertical through-hole. The sample transfer vertical through-hole is formed on a surface where the sample storage vertical through-hole is viewed, penetrates the sample loading part, and is connected to the loading bar inserting hole.
