Microscope Micro-Distance Adjustment for 3D Sample Observation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional portable minimized microscope devices struggle with adjusting the distance between the objective lens and the sample due to fixed focal lengths and sample thickness variations, limiting observation of three-dimensional samples to specific sections, requiring cumbersome sample repositioning or preparation.
Innovation Solution
A micro distance adjusting mechanism with a first and second element, connected by a screw-connecting portion, allows for relative rotation and movement within a 0.1mm to 3.5mm range, enabling quick adjustment of the objective lens position relative to the sample.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the focal length of the objective lens is fixed and the distance between the objective lens and the sample carrier is fixed, then the microscope device has a simple structure, but it cannot observe three-dimensional samples at different sections or surfaces with varying thicknesses
Solution Approach 1:
The patent applies the dynamics principle by making the distance between the objective lens and the sample carrier adjustable through a micro distance adjusting mechanism. The first and second elements can relatively move along the optical route, allowing the objective lens to dynamically adjust its position to accommodate different sample thicknesses and sections, thereby resolving the contradiction between adaptability and structural simplicity.
Solution Approach 2:
The patent implements parameter changes by enabling the distance parameter between the objective lens and the sample carrier to be variable rather than fixed. The micro distance adjusting mechanism allows this parameter to change within a specific range (0.1mm to 3.5mm), facilitating observation of three-dimensional samples at different depths and sections while maintaining overall structural simplicity.
2Adaptability or versatility
If the portable minimized microscope device maintains constant relative position with the smart communication device, then the device structure is simplified, but it cannot adapt to different sample thicknesses or improper sample positions
Solution Approach 1:
The patent applies dynamics by introducing a micro distance adjusting mechanism that allows the objective lens to dynamically adjust its position relative to the sample carrier. This enables adaptation to different sample thicknesses and improper sample positions without requiring complex repositioning operations, thereby improving ease of operation while maintaining structural simplicity.
Solution Approach 2:
The micro distance adjusting mechanism enables the microscope device to self-adjust to different sample conditions. The first and second elements can relatively move to automatically accommodate varying sample thicknesses, reducing the need for manual sample repositioning or preparation, thus improving operational convenience.
3Length of moving object
If the micro distance adjusting mechanism allows relative movement between first and second elements, then the distance adjustment range is increased, but the relative rotation range is limited to less than 360 degrees
Solution Approach 1:
The patent implements parameter changes by defining specific ranges for the relative movement between the first and second elements. The distance adjustment range is set to 0.1mm to 3.5mm, and the relative rotation range is limited to less than 360 degrees. This parameterization allows for sufficient distance adjustment capability while keeping the rotation mechanism simple and manageable.

AI summary
A micro distance adjusting mechanism includes a first element having a first body, a second element having a second body, and a connection member. The first body has a first through hole on an optical route, and the second body has a second through hole on the optical route. The objective lens unit is telescoped in the first and second through holes. The first body and the second body are relative-movably connected, and the first and second bodies make a relative movement during the micro distance adjustment. The connection member is connected to the first body or the second body in an axial or radial direction. The relative movement includes a relative displacement and/or a relative rotation, the range of the relative rotation is less than 360 degrees, and the range of the micro distance adjustment is 0.1mm~3.5mm.
