Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple test modules are integrated on a single base to detect multiple water quality parameters simultaneously, then detection efficiency and productivity are improved, but device complexity and manufacturing precision requirements increase
Solution Approach 1:
The test paper is divided into multiple independent test modules (first test module for chlorine, second test module for hardness, third test module for pH, fourth test module for cyanuric acid, fifth test module for bromine, sixth test module for alkalinity) arranged on a single base. Each module contains specific detection substances and is spatially separated to prevent interference, allowing simultaneous detection of multiple parameters while maintaining functional independence.
Solution Approach 2:
A single test paper base integrates multiple test modules that can detect different water quality parameters (chlorine, hardness, pH, cyanuric acid, bromine, alkalinity) simultaneously. This multi-functional design eliminates the need for separate test papers for each parameter, improving detection efficiency and productivity.
2Area of stationary object
If multiple test modules are placed close together on the base to save space, then area utilization is improved, but color bleeding between modules occurs reducing measurement precision
Solution Approach 1:
Hydrophobic isolation lines are introduced between adjacent test modules on the base. These isolation lines act as barriers that prevent water from spreading between modules, thereby preventing color bleeding and interference between adjacent detection zones while allowing the modules to be arranged in close proximity for efficient space utilization.
3Measurement precision
If hydrophobic isolation lines are added between test modules to prevent color bleeding, then measurement precision is improved, but device complexity and manufacturing steps increase
Solution Approach 1:
Hydrophobic isolation lines in the form of thin film structures are applied between test modules. These thin film barriers effectively prevent water spreading and color bleeding between adjacent modules, improving detection accuracy. The thin film design minimizes the added complexity compared to bulkier isolation structures.
4Measurement precision
If specific detection substances and carriers are used for each parameter to prevent interference, then measurement precision is improved, but loss of substance and manufacturing cost increase
Solution Approach 1:
Each test module is equipped with specific detection substances tailored to the parameter it detects (e.g., DPD for chlorine, EBT indicator for hardness, phenol red for pH). This localized optimization ensures high detection accuracy for each parameter while minimizing unnecessary reagent usage in other modules, as each substance is precisely where needed and not wasted in other detection zones.
