Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional detection devices are used for heavy metal ions, then detection capability is provided, but manufacturing cost is high and portability is poor
Solution Approach 1:
The patent extracts the image capturing unit and data processing unit from the detection device, relying instead on the mobile electronic device's camera and processor. This extraction significantly reduces the manufacturing cost and improves portability while maintaining detection capability through the plasma generation unit and light decomposing unit that remain in the portable device.
Solution Approach 2:
The mobile electronic device serves multiple functions: it acts as the power source, provides the image capturing unit for spectral analysis, and handles data processing. This multi-functionality eliminates the need for separate components in the detection device, reducing its complexity and cost while maintaining full detection capability.
2Measurement precision
If the device includes an image capturing unit and data processing unit, then detection accuracy is improved, but manufacturing cost increases
Solution Approach 1:
The image capturing unit and data processing unit are extracted from the detection device and transferred to the mobile electronic device. The detection device only retains the plasma generation unit and light decomposing unit, significantly reducing manufacturing cost while the mobile device's camera and processor maintain detection accuracy through spectral analysis.
Solution Approach 2:
The mobile electronic device acts as an intermediary that provides the image capturing and data processing functions. This intermediary approach allows the detection device to focus on the core plasma generation and light decomposition functions, reducing its manufacturing complexity and cost while maintaining accuracy through the mobile device's computational capabilities.
