Sample Imaging with Light-Guided Container ID Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image capturing devices struggle to associate biological sample images with culture information efficiently, as conventional methods require separate dedicated devices for acquiring container identification information, which can obscure the image and necessitate manual handling.
Innovation Solution
An image capturing device that includes an image capturing unit, a light guide unit, and a mobile unit to change positions, allowing simultaneous imaging of a sample and identification information on a surface different from the bottom, without the need for additional dedicated devices, by using a light guide unit to guide light from the identification surface to the image capturing unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a dedicated reading device or camera is used to acquire container identification information, then the identification information can be acquired, but the device complexity increases and the image quality may be obscured
Solution Approach 1:
The patent combines the identification information acquisition function with the sample imaging function into a single image capturing device. The image capturing device includes both a light guide unit for guiding light from the identification surface and an image capturing unit for capturing images, eliminating the need for separate dedicated reading devices or cameras.
Solution Approach 2:
The image capturing device is designed to perform multiple functions: it can capture images of the sample through the bottom surface and also acquire identification information from the identification surface. This multi-functional design reduces device complexity while maintaining acquisition accuracy.
2Loss of information
If the image capturing device is positioned to image the identification surface, then the identification information can be acquired, but the sample imaging is blocked
Solution Approach 1:
The patent divides the imaging process into two separate positional states: a first relative position for acquiring identification information from the identification surface, and a second relative position for imaging the sample through the bottom surface. The mobile unit transitions between these positions to perform different functions sequentially.
Solution Approach 2:
The patent employs a mobile unit that can dynamically change the relative position of the image capturing device with respect to the container. This dynamic positioning allows the device to switch between capturing identification information and imaging samples, resolving the conflict between these two functions.
3Measurement precision
If the optical axis intersects the container bottom surface, then the sample can be imaged, but the identification surface cannot be observed
Solution Approach 1:
The patent performs identification information acquisition as a preliminary action before sample imaging. The mobile unit first positions the device to acquire identification information, then transitions to the second relative position for sample imaging. This sequential approach ensures both functions are completed without interference.
4Adaptability or versatility
If separate dedicated devices are used for identification information acquisition, then the functions are specialized, but the installation complexity and handling time increase
Solution Approach 1:
The patent merges the identification information acquisition function and sample imaging function into a single integrated image capturing device, reducing installation complexity and simplifying handling operations while maintaining the specialized capabilities of both functions.

AI summary
An image capturing device for observing a sample housed in a container includes: an image capturing unit; a light guide unit that guides light from an identification surface to the image capturing unit, the identification surface being a surface of the container different from a bottom surface of the container and to which identification information is attached; and a mobile unit that changes a relative position of the image capturing unit with respect to the container. In a first relative position in which the optical axis of the image capturing unit deviates from the container, the image capturing unit images the identification surface via the light guide unit. In a second relative position in which the optical axis of the image capturing unit intersects the container, the image capturing unit images the sample via the bottom surface.
