Solution Overview
Problem
Conventional scanning probe microscopes require manual replacement of probes, which is inconvenient and often results in misalignment of the probe position, necessitating rearrangement of optical systems.
Innovation Solution
A scanning probe microscope with a carrier holder and tray system that allows for automatic probe replacement and precise reattachment using protrusions and holes, eliminating the need for manual alignment and optical system rearrangement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If manual probe replacement is used in conventional SPM, then the probe can be replaced, but the operation convenience deteriorates and time is lost
Solution Approach 1:
The system enables automatic probe replacement through self-service mechanisms where the scanner head automatically detaches and reattaches probes without manual intervention. The carrier holder with protrusions and carriers with corresponding holes work together to achieve automatic positioning and attachment, eliminating the need for manual probe replacement operations.
2Productivity
If manual probe replacement is used in conventional SPM, then the probe can be replaced, but the replacement time increases
Solution Approach 1:
Multiple probes are pre-loaded onto carriers in advance and stored in the tray. When probe replacement is needed, the system simply needs to exchange the entire carrier rather than manually handling individual probes. This preliminary preparation of probes on carriers significantly reduces the time required for probe replacement operations.
3Manufacturing precision
If manual probe replacement is used in conventional SPM, then the probe can be replaced, but the positioning precision deteriorates
Solution Approach 1:
The carrier holder is designed with specific local features (protrusions) that correspond to matching features (holes) on the carriers. This localized precision fitting mechanism ensures that each carrier is attached at the exact correct position, maintaining consistent probe positioning accuracy regardless of how many times probes are replaced.
4Ease of operation
If manual probe replacement is used in conventional SPM, then the probe can be replaced, but the device complexity increases due to optical system rearrangement
Solution Approach 1:
The carrier and carrier holder design creates a reproducible, standardized interface that ensures the probe is always attached in the same position. This copying of the precise positioning geometry eliminates the need for complex optical system rearrangements, as the probe tip consistently returns to the same location relative to the optical systems.
