Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple motors and electrical control systems are used to switch modules for different fluorescent substances, then the system can achieve switching functionality, but the volume and cost of the apparatus increase
Solution Approach 1:
The patent combines multiple switching functions into a single mechanical module that simultaneously switches the light source, excitation filter, and emission filter. This single module replaces what would traditionally require multiple separate motors and control systems, thereby reducing the overall apparatus volume while maintaining full switching functionality for different fluorescent substances.
Solution Approach 2:
The invented switching module serves multiple functions simultaneously: it controls the light source selection, excitation filter selection, and emission filter selection all through one mechanical actuation. This multi-functional design eliminates the need for separate switching mechanisms for each component, reducing both volume and cost.
2Adaptability or versatility
If multiple motors and electrical control signals are used to control each module, then the system can achieve switching capability, but the switching speed and synchronicity deteriorate
Solution Approach 1:
By merging the switching control of multiple optical components into a single mechanically coupled module, all components switch simultaneously in one motion. This eliminates the delays and synchronicity issues inherent in multi-motor electrical control systems, achieving much faster and more synchronized switching.
3Adaptability or versatility
If multiple motors are used to control each module and lens, then the switching functionality is achieved, but the cost of the apparatus increases
Solution Approach 1:
The patent merges multiple expensive motor components into a single mechanical switching module that can be manufactured more simply and at lower cost. The single-module design reduces the bill of materials and assembly complexity, directly reducing apparatus cost while maintaining full switching functionality.

The system achieves efficient switching of excitation beams with reduced volume and cost, improving synchronicity and shortening configuration time by using a single motor and meshing structures for rotational synchronicity, enabling precise matching of light sources, filters, and spectroscopic modules to the device under test.
Implementation Method 1
a link belt pivotally connecting the first pivotal connection element, the second pivotal connection element and the motor, wherein the motor drives the first shaft and the second shaft to rotate synchronously through the link belt
Implementation Method 2
A light source corresponding in position to a reflecting surface of the first reflecting component is changed because of rotation of the first shaft to provide the excitation beam of the light source to the optical transmission path

AI summary
A fluorescence detection system is provided and adapted to provide a selectable excitation beam to an optical transmission path for irradiation of a device under test, including a driving module, a lighting module, a first optical module and a second optical module. The driving module includes a first shaft and a second shaft parallel thereto. The lighting module is fixed to the first shaft. The first optical module and the second optical module are fixed to the second shaft. A driving operation enables the driving module to rotate the lighting module, the first optical module and the second optical module simultaneously, determining quickly a combination of one light source, one filter and one spectroscopic module on the optical transmission path, with the combination corresponding in position to the device under test, so as to reduce the volume and cost the fluorescence detection system.
