Solution Overview
Problem
Traditional fixture structures for position fine-tuning in device testing are bulky, leading to labor-intensive and time-consuming procedures, and often result in inaccurate testing results or damage to the device under test due to improper alignment.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a traditional fixture structure is used for position fine-tuning, then the alignment can be achieved, but the structure becomes bulky and the procedure consumes labor and time
Solution Approach 1:
The fixture structure is divided into multiple independent plates (first plate, second plate, third plate) that can be separately positioned and adjusted. Each plate has its own linear groove and guide slider components, allowing independent fine-tuning of position without requiring a bulky monolithic structure. This segmentation enables precise alignment while reducing overall structural complexity.
Solution Approach 2:
The invention introduces orthogonal linear grooves (first linear groove along X-axis, second linear groove along Y-axis) that allow position adjustment in multiple dimensions. The guide sliders move along these orthogonal grooves, enabling two-dimensional fine-tuning of the second plate's position relative to the first plate, achieving precise alignment without increasing structural bulk.
2Manufacturing precision
If a traditional fixture structure is used for position fine-tuning, then the alignment can be achieved, but the procedure becomes time-consuming
Solution Approach 1:
The fixture structure incorporates movable guide sliders that can dynamically adjust the position of the second plate along the linear grooves. This dynamic adjustment mechanism allows operators to quickly fine-tune alignment by simply moving the sliders rather than performing complex manual adjustments, significantly reducing the time required for position fine-tuning while maintaining high precision.
Solution Approach 2:
The invention replaces complex mechanical adjustment mechanisms with a simpler guide slider system that moves along predefined linear grooves. This substitution eliminates the need for complicated procedures while maintaining alignment precision, as the grooves constrain the movement paths and the sliders provide direct positional control.
3Ease of operation
If a regular rail structure is used, then the position adjustment can be achieved, but the overall volume and thickness increase
Solution Approach 1:
The guide sliders are nested within the linear grooves cut into the plates, with the sliders fitting inside the groove channels. This nesting arrangement allows the position adjustment mechanism to be integrated within the plate thickness rather than adding external rail structures, significantly reducing the overall volume and thickness of the fixture while maintaining full position adjustment capability.

AI summary
A position fine-tuning structure includes a first plate, a second plate and a guide slider. A top surface of the first plate is recessed with a first linear groove. A bottom surface of the second plate is recessed with a second linear groove. The bottom surface of the second plate directly covers the top surface of the first plate, so that the second linear groove is orthogonal to and in communication with to the first linear groove. The guide slider includes a first pillar and a second pillar which are overlapped with and orthogonal to each other. The first pillar is parallel to the first linear groove and slidably located within the first linear groove, and the second pillar is parallel to the second linear groove and slidably located within the second linear groove.
