Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a combination of mirror group, scanning sensor, and light source is added near the device carrier to obtain better image resolution, then the detection precision is improved, but the device volume and weight increase significantly
Solution Approach 1:
The patent combines the scanning sensor and mirror group into a single integrated scanning detection assembly that moves together as one unit, eliminating the need for separate moving components. This merging reduces the overall device volume and weight while maintaining the detection precision through the coordinated operation of the integrated components.
Solution Approach 2:
The scanning detection assembly is designed to perform multiple functions simultaneously - scanning, detecting, and imaging - using a single integrated structure. This multi-functionality eliminates the need for separate dedicated components for each function, thereby reducing device volume and weight while achieving the required image resolution.

Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device achieves high-efficiency detection and high accuracy in locating biological particles by integrating the photomultiplier tube and charge-coupled device, reducing the overall volume and weight, and minimizing mechanical interference.
Implementation Method 1
The light source emits a high-penetration light (e.g. near-infrared light, laser light) and illuminates a plurality of biological particles on a device carrier, so that at least part of the biological particles emit an emission light after being illuminated
Implementation Method 2
The filter and spectroscope group includes a beam splitter located on a light path of the emission light and is adapted to separate the incident emission light into a first detecting light and a second detecting light that account for different proportions of the emission light
Data Source
AI summary
A detecting device for detecting biological particles includes an optical system including an excitation light source, a filter and spectroscope group, a photomultiplier tube, and a charge-coupled device. The excitation light source illuminates the biological particles on a detecting carrier of the detecting device. A kind of target biological particles in the biological particles is excited to generate an emission light. The emission light enters the filter and spectroscope group to be separated into a first detecting light and a second detecting light. After the photomultiplier tube receives the first detecting light, the photomultiplier tube transmits a regional positioning signal to a processor of the detecting device. After the charge-coupled device receives the second detecting light, the charge-coupled device transmits an image signal to the processor. The processor obtains a precise location of the target biological particles based on the regional positioning signal and the image signal. A detecting method of the detecting device is also provided.
