Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional light calibration methods are used, then light source intensity can be measured, but the process becomes complex and costly due to disassembly requirements and expensive equipment
Solution Approach 1:
The light detector is integrated directly into the carrier for biochemical examination, merging the calibration function with the sample carrier. This eliminates the need for separate calibration equipment and simplifies the calibration process while maintaining measurement precision.
Solution Approach 2:
The system performs self-calibration by using the carrier with integrated light detector to measure light source intensity directly within the device. This self-service approach eliminates the need for external calibration equipment and complex disassembly procedures.
2Weight of moving object
If light sources are integrated into biological detection devices, then device portability is improved, but light source calibration becomes more difficult due to varying designs and positions
Solution Approach 1:
The carrier with integrated light detector serves multiple functions: it acts as both the sample carrier for biochemical examination and the calibration tool for light source intensity measurement. This universal design works across different biological detection device configurations without requiring device-specific calibration procedures.
Solution Approach 2:
The carrier acts as an intermediary between the light source and the measurement system. By integrating the light detector into the carrier, the system mediates the calibration process directly at the point where light interacts with samples, simplifying operation across various device designs.
3Measurement precision
If expensive light source calibration equipment is used, then measurement accuracy is improved, but equipment cost and device weight increase
Solution Approach 1:
The light detector is merged with the carrier structure, eliminating the need for separate expensive calibration equipment. This integration maintains measurement accuracy while significantly reducing equipment costs and overall device weight.
Solution Approach 2:
Instead of using expensive external calibration equipment, the system uses a simplified light detector integrated into the carrier that copies the essential measurement function. This approach achieves sufficient measurement accuracy at much lower cost.

AI summary
An operating method of a biological detection calibration system, adapted for a biological detection device which includes a light source for emitting a light to detect a biological sample. A step is performed to detect whether a light calibration device exists on the biological detection device, wherein the light calibration device includes a carrier and a calibration sample disposed on the carrier, and the calibration sample includes a light detector. If the light calibration device exists, the intensity of the light detected by the light detector is read to determine whether the intensity of the light detected by the light detector is less than a predetermined value. If the intensity of the light detected by the light detector is less than the predetermined value, a driving voltage of the light source is enhanced, such that the intensity of the light detected by the light detector reaches the predetermined value.
