Rotary Imaging System Camera Rotation for Living Sample Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing living imaging technologies face challenges with sample slippage during movement, leading to inaccurate image information and increased system costs due to the need for multiple cameras to capture images from different positions.
Innovation Solution
A rotary imaging system where the camera unit is fixedly connected to a rotation module, allowing it to rotate independently with respect to the sample table, using a circular guide rail and pulley system to maintain stability and accuracy, enabling flexible imaging angles without moving the sample table.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the sample table is driven by a three-axis motion mechanism to achieve translation or rotation, then the sample can be imaged at different positions, but the sample may slide during movement causing image information to deviate
Solution Approach 1:
Instead of moving the sample table to change imaging angles, the patent inverts the approach by rotating the camera unit around the stationary sample. The rotation unit drives the camera unit to rotate along a circular arc, allowing the sample to remain fixed while achieving multi-angle imaging, thus eliminating sample slippage and maintaining image accuracy
Solution Approach 2:
The patent segments the imaging system into independent components: a stationary sample table unit and a rotatable camera unit with multiple cameras. Each camera can be independently positioned at different angles around the sample, allowing precise angular adjustment without affecting the sample position, thereby resolving the contradiction between adaptability and measurement precision
2Adaptability or versatility
If multiple cameras are used to image the sample at different positions, then complete image information can be obtained, but the system cost increases greatly
Solution Approach 1:
The patent makes a single camera unit multi-functional by enabling it to rotate to multiple positions around the sample. The rotation unit allows one camera unit to perform the function of multiple stationary cameras by capturing images from different angles sequentially, significantly reducing system cost while maintaining complete imaging capability
Solution Approach 2:
The patent transforms the static multi-camera system into a dynamic single-camera-unit system. The camera unit can dynamically rotate to different angular positions around the sample, adapting its position as needed. This dynamic capability replaces the need for multiple fixed cameras, reducing device complexity and cost while preserving multi-position imaging functionality
3Adaptability or versatility
If the camera unit rotates with respect to the sample table unit, then flexible imaging angles are achieved, but mechanical loss may increase
Solution Approach 1:
The patent uses a circular guide rail with pulleys to guide the camera unit along a circular arc path during rotation. This curved trajectory allows smooth rotational movement with continuous contact guidance, reducing mechanical friction and energy loss compared to angular or linear motion mechanisms, while achieving flexible imaging angle adjustment
