Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If light is emitted to the entire sensor matrix, then all regions are illuminated for measurement, but unnecessary light exposure increases energy consumption and reduces measurement precision
Solution Approach 1:
The illumination device emits light selectively to only those regions of the sensor matrix where test samples are present, rather than illuminating the entire matrix. This localized illumination approach reduces unnecessary light exposure and energy consumption while maintaining measurement precision for the actual sample regions.
Solution Approach 2:
The sensor matrix is divided into multiple regions, and the illumination device selectively illuminates only the specific regions containing test samples. This segmentation allows the system to target light emission precisely where needed, improving energy efficiency without compromising measurement accuracy.
2Quantity of substance
If light is emitted to all regions, then complete coverage is achieved, but resource consumption increases
Solution Approach 1:
The system applies local quality by directing light emission only to regions containing test samples, thereby reducing the quantity of light resource consumed and minimizing energy loss from illuminating empty or irrelevant areas of the sensor matrix.
Solution Approach 2:
Instead of providing full coverage illumination to the entire sensor matrix, the system applies partial action by illuminating only the necessary regions where samples are located, thereby conserving light resources and reducing energy consumption.
3Loss of energy
If selective region irradiation is implemented, then energy efficiency improves, but device complexity increases
Solution Approach 1:
The system uses feedback mechanisms to determine which regions of the sensor matrix contain test samples and requires illumination. By continuously monitoring sample positions and adjusting light emission accordingly, the system achieves energy efficiency while managing control complexity through intelligent feedback-based decision making.
Solution Approach 2:
The illumination device operates autonomously by detecting the presence and position of test samples and automatically adjusting its illumination pattern. This self-service capability reduces the need for complex external control systems while maintaining energy efficiency through adaptive, sample-driven illumination decisions.

AI summary
According to one embodiment, the illumination device includes a lighting unit and a control unit. The lighting unit emits light at the intensity to be emitted toward the region to be irradiated in a two-dimensional region of a measurement device. The measurement device acquires optical information and biochemical information and/or electrical information for an object corresponding with positional information. The control unit determines the region to be irradiated and the intensity to be emitted, based on the biochemical or electrical information by the measurement device, the positional information of them, and the threshold conditions predetermined, and controls the irradiation of the lighting unit depending on them.
