Slide Operation Dovetail Groove Sliding Stage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dovetail groove sliding stages are bulky, complex, and difficult to operate due to the reliance on control knobs for positional adjustment, leading to slow and cumbersome movement of sliding components.
Innovation Solution
A slide operation-type dovetail groove sliding stage that eliminates the control knob by using a sliding lock screw, force application rod, and reaction force rod to directly manipulate the sliding component, allowing for easy operation and compact design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a control knob with rack-and-pinion or feed-screw mechanism is used for positional adjustment, then fine adjustment and load bearing are achieved, but the device becomes bulky and operation becomes slow
Solution Approach 1:
The patent extracts and removes the control knob and its associated rack-and-pinion or feed-screw mechanism from the sliding stage. By eliminating these complex transmission components, the invention achieves both faster operation (direct sliding without rotational conversion) and reduced device size, while maintaining positioning capability through the dovetail groove structure itself
Solution Approach 2:
Instead of using a rotational control mechanism (knob) to achieve linear movement, the invention inverts the approach by enabling direct linear sliding through the dovetail groove. The positioning function is inverted from being achieved through rotational-to-linear conversion to being achieved through direct linear motion control
2Manufacturing precision
If a control knob mechanism is used for sliding the component, then positional adjustment is achieved, but the height and complexity of the device increase
Solution Approach 1:
The patent removes the control knob and its complex transmission mechanism (rack-and-pinion or feed-screw) from the sliding stage design. This extraction eliminates multiple moving parts, reduces mechanical complexity, and lowers the device height while preserving the essential positioning function through the simplified dovetail groove structure
Solution Approach 2:
The dovetail groove structure itself is made to serve multiple functions: it provides both the sliding guide and the positioning mechanism. By making the groove structure multi-functional, the invention eliminates the need for separate control mechanisms, thereby reducing overall device complexity
3Ease of operation
If rack-and-pinion or feed-screw mechanism is used, then controlled sliding is achieved, but the device height increases making it bulky
Solution Approach 1:
The patent extracts and eliminates the control knob and its transmission mechanism from the sliding stage. This removal directly reduces the vertical height of the device by eliminating the need for rotational-to-linear conversion components, resulting in a more compact design while maintaining controlled sliding capability through the dovetail groove structure

Function Achieved in This Case
The solution simplifies the driving mechanism, improves operability, and reduces the height of the sliding stage, enabling quick and precise positional adjustments without the need for a control knob, resulting in a more compact and user-friendly system.

AI summary
The slide operation-type dovetail groove sliding stage may include a sliding lock screw for locking sliding of a sliding component, by causing the screw to abut on an inverted triangle-shaped protrusion, provided on a sidewall of a sliding component approximately parallel to a sliding direction and coupled to the sliding component, to bring the protrusion into contact with a dovetail of the fixed component and by tightening the screw. The sliding lock screw may be used as a sliding adjustment screw for performing fine adjustment of a degree of sliding of the sliding component with respect to the fixed component by adjusting an amount of rotation of the screw which abuts on the protrusion to bring it into contact with the dovetail of the sliding component, and a driving means which an operator grasps to perform an operation of sliding the sliding component to a desired position.
