Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sample holders for ion beam cutting and polishing face challenges in handling samples, especially in difficult conditions, such as inside a glove box, and inadequate cooling, leading to potential deformation or damage of heat-sensitive samples.
Innovation Solution
A sample holder with a retaining mechanism that can be mechanically actuated to open and close, facilitated by a loading device, allowing easy insertion and removal of samples, and incorporating a design that supports cooling through thermally conductive materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional sample holder design is used, then the sample can be held during ion beam processing, but the insertion and removal of samples is difficult and time-consuming, especially in glove box conditions
Solution Approach 1:
The sample holder employs a dynamic retaining mechanism that can transition between open and closed states. The retaining component is movable along the holding component, allowing the holder to open for easy sample insertion/removal and close for secure sample retention during ion beam processing, thus resolving the contradiction between ease of operation and time loss
Solution Approach 2:
The sample holder is divided into functionally independent components: a holding component, a retaining component, and a movable mechanism. This segmentation allows the retaining mechanism to be actuated independently to facilitate quick sample loading while maintaining secure clamping during operation, addressing both ease of operation and time efficiency
2Reliability
If the retaining mechanism is made secure to hold the sample firmly, then sample stability during ion beam processing is improved, but the mechanism becomes more complex and harder to operate in confined spaces
Solution Approach 1:
The retaining mechanism utilizes spring-loaded or elastic deformation-based retention where the holding component automatically exerts clamping force on the sample. This self-service mechanism provides reliable sample retention without requiring complex actuation systems, maintaining both high reliability and operational simplicity
Solution Approach 2:
An intermediary mechanical element (such as a spring or elastic component) is introduced between the actuating force and the sample retention function. This intermediary converts simple linear motion into effective clamping force, achieving reliable sample holding with a relatively simple mechanism that is easy to operate in confined glove box environments
3Object-affected harmful factors
If cooling mechanisms are added to the sample holder, then heat-sensitive samples are protected from ion beam heating, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The cooling function is extracted as a separate, modular component that can be attached to or integrated with the sample holder. This allows the basic sample holder structure to remain simple and easy to manufacture, while the cooling mechanism can be added only when heat-sensitive samples require protection, balancing manufacturing ease with heat protection capability

AI summary
A sample holder includes a main component comprising a first surface area, and a retaining mechanism comprising a holding component. The retaining mechanism is configured to retain a sample between the holding component of the retaining mechanism and the first surface area in a closed state of the retaining mechanism. The retaining mechanism is further configured to enter an opened state upon mechanical actuation of the retaining mechanism. The opened state allows insertion and removal of the sample. The retaining mechanism is further configured to revert to the closed state once the mechanical actuation is removed.
