Solution Overview
Problem
Existing sample holders for ion beam cutting and polishing, particularly in glove boxes, face challenges with precise alignment, inadequate cooling, and difficult sample insertion, leading to potential damage and reduced preparation quality.
Innovation Solution
A sample holder with a mechanical actuation-based retaining mechanism that automatically opens and closes, combined with a loading device for easy sample insertion, and enhanced cooling capabilities using thermally conductive materials to support fragile and heat-sensitive samples.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a traditional sample holder design is used, then the structure is simple, but the sample insertion is difficult and imprecise alignment cannot be achieved
Solution Approach 1:
The sample holder is divided into a main body and a separate retaining mechanism that can be independently actuated. This segmentation allows the alignment features (main body) to be precisely positioned while the retaining mechanism provides easy operational control for sample insertion and removal.
Solution Approach 2:
A retaining mechanism acts as an intermediary between the operator and the sample. This mediator provides a controlled interface that facilitates precise sample placement while maintaining ease of operation through mechanical actuation that automatically reverts to a closed state.
2Ease of operation
If the retaining mechanism remains closed, then the sample is securely retained, but the sample cannot be inserted or removed
Solution Approach 1:
The retaining mechanism transitions between static closed states (for secure retention) and a dynamically opened state (for sample insertion/removal). The mechanical actuation provides controlled dynamic access while the automatic reversion ensures reliable return to the secure closed state, balancing ease of operation with retention reliability.

Function Achieved in This Case
Facilitates quick and precise sample insertion, reduces preparation time, increases success rate, and ensures effective cooling to prevent thermal damage during ion milling processes.
Implementation Method 1
The retaining mechanism may comprise a spring, with the spring being compressed when the retaining mechanism is actuated. The spring, in its preloaded state, may press the holding component of the retaining mechanism towards the first surface area of the main component
Implementation Method 2
enhanced cooling capabilities using thermally conductive materials to support fragile and heat-sensitive samples

AI summary
Examples relate to a sample holder (100), to a loading device (200), and to a method for inserting a sample into a sample holder. The sample holder (100) comprises a main component (110) comprising a first surface area (112). The sample holder (100) further comprises a retaining mechanism (120) comprising a holding component (122). The retaining mechanism (120) is configured to retain a sample (14) between the holding component (122) of the retaining mechanism and the first surface area (112) in a closed state of the retaining mechanism. The retaining mechanism is configured to enter an opened state upon mechanical actuation of the retaining mechanism, the opened state allowing insertion and removal of the sample, with the retaining mechanism being configured to revert to the closed state once the mechanical actuation is removed.
