Specimen Holder Tilt Adjustment for Parallel Surface Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing specimen holders lack the ability to adjust the tilt of specimens during preparation for ion beam milling and mechanical polishing, which is essential for achieving parallel surfaces and optimal milling positions.
Innovation Solution
A specimen holder with a holder main body, a specimen mount, and a pressing member that includes a rod-like adjustment jig, allowing the specimen mount to be tilted by inserting the adjustment jig into a through-hole, enabling adjustable tilt and position adjustments for precise specimen alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a specimen holder without tilt adjustment capability is used, then the device complexity is reduced, but the manufacturing precision of the specimen surface is insufficient
Solution Approach 1:
The specimen holder employs a dynamic tilt adjustment mechanism where the specimen mount can be tilted relative to the holder main body by rotating the pressing member around a pivot point. This allows the holder to transition from a fixed to an adjustable configuration, enabling precise control of the specimen surface angle during mechanical polishing to achieve parallel surfaces without over-complicating the overall structure.
Solution Approach 2:
The holder enables change of the tilt angle parameter of the specimen mount. By adjusting the pressing member's rotational position, the tilt angle can be varied to optimize the specimen surface orientation for polishing operations, thereby improving manufacturing precision while maintaining a relatively simple structural design.
2Ease of operation
If a specimen holder with tilt adjustment mechanism is added, then the ease of operation for specimen alignment is improved, but the device complexity increases
Solution Approach 1:
The pressing member serves dual functions: it applies pressing force to secure the specimen mount to the holder main body, and it acts as the adjustment mechanism for tilting the specimen mount. This self-service design allows the same component to perform both clamping and alignment adjustment, improving ease of operation without significantly increasing device complexity.

AI summary
A specimen holder includes a holder main body, a specimen mount to which a specimen is to be fixed, and a pressing member which slidably presses the specimen mount against the holder main body, wherein a through-hole is provided in the specimen mount, and the specimen mount is tilted with respect to the holder main body by tilting a rod-like member which is inserted into the through-hole.
