Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If separate equipment for ion component analysis and heavy metal component analysis is used, then analysis capability is improved, but facility space consumption and maintenance requirements increase
Solution Approach 1:
The patent integrates ion component analysis equipment and heavy metal component analysis equipment into a single integrated analysis platform. The system uses a shared sample introduction unit with multiple syringe pumps that can selectively introduce samples to different analysis modules, thereby reducing facility space while maintaining both analysis capabilities
Solution Approach 2:
The sample introduction unit is designed as a universal platform that can serve multiple analysis functions. It includes a first syringe pump for ion analysis and a second syringe pump for heavy metal analysis, both controlled by a single control unit that can switch between different analysis modes and equipment configurations
2Measurement precision
If separate equipment for ion component analysis and heavy metal component analysis is used, then analysis capability is improved, but maintenance requirements increase
Solution Approach 1:
By merging ion and heavy metal analysis equipment into one integrated system, the patent reduces the total number of equipment units that require maintenance. The shared components such as the sample introduction unit and control system need to be maintained only once, rather than separately for each analysis type
Solution Approach 2:
The universal sample introduction unit with multiple syringe pumps can be maintained as a single platform. The control unit manages both ion and heavy metal analysis functions, reducing the complexity of maintaining separate control systems and simplifying operational procedures
3Measurement precision
If traditional analysis methods are used, then measurement is performed, but abnormal data fluctuations occur frequently due to suspended solids
Solution Approach 1:
The patent implements preliminary filtration of the wastewater sample before analysis using the pretreatment sampler. This preliminary action removes suspended solids that would otherwise interfere with the analysis, preventing abnormal data fluctuations and improving measurement reliability
Solution Approach 2:
The system introduces an intermediary filtration step between sample collection and analysis. The pretreatment sampler acts as an intermediary that separates suspended solids from the liquid phase, ensuring that only clarified samples reach the analysis equipment, thereby improving data stability
