Solution Overview
Problem
Existing photon measuring and reading devices for chemiluminescence immunoanalyzers have complex structures due to separate control mechanisms for the distance between the detection device and the detected object and the shutter, leading to inconsistent operations and affected data quality.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate control mechanisms are used for the distance between detection device and detected object and for the shutter, then the device can perform independent control of each function, but the overall structure becomes complex and inconsistent operations may occur
Solution Approach 1:
The patent combines the control of photon counter movement and shutter operation into a single integrated control mechanism. The control system receives one control signal and simultaneously actuates both the photon counter positioning mechanism and the shutter mechanism, ensuring synchronized operation while reducing structural complexity compared to separate control systems
2Adaptability or versatility
If separate control mechanisms are used for photon counter movement and shutter control, then each component can be controlled independently, but inconsistent operations occur affecting data quality
Solution Approach 1:
The control system integrates photon counter positioning and shutter control into a single synchronized operation. A single control signal triggers both the movement of the photon counter to the detection position and the opening/closing of the shutter simultaneously, ensuring operational consistency and preventing data quality issues caused by timing mismatches
3Device complexity
If fixed optical aperture is used in photon counter, then the structure is simple, but the application range is limited
Solution Approach 1:
The patent replaces the fixed optical aperture with a variable aperture mechanism that can dynamically adjust its opening size. The aperture is configured to be movable relative to the photon counter's light-receiving surface, allowing the detection area to be adjusted according to different measurement requirements, thereby expanding the device's application range without significantly complicating the overall structure

Implementation Method 1
a double head motor with an output shaft at both ends
Implementation Method 2
a linkage mechanism for driving the sliding rod to move up and down is arranged between the output shaft at the tail end of the double head motor and the sliding rod
Implementation Method 3
The core detector of the chemiluminescence immunoanalyzer is a photomultiplier tube, which is a vacuum electronic device that can convert weak optical signal into electrical signal
Implementation Method 4
detected by single photon and transmitted to amplifier, and amplified by high-voltage current
Implementation Method 5
The chemiluminescence analysis system forms an excited state intermediate by catalyzing a chemiluminescent substance using a catalyst and oxidizing the same using an oxidant. When the excited state intermediate returns to a stable ground state, photons are emitted at the same time
