Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If on-site testing is implemented, then analysis speed and autonomy are improved, but measurement precision and reliability deteriorate
Solution Approach 1:
The patent introduces a sealed cartridge as an intermediary component that contains the sensor and sample chamber. This cartridge acts as a mediator between the sample collection cup and the electronic reader, ensuring that the sensor only contacts the sample fluid within a controlled, sealed environment. The cartridge's sealing mechanism prevents contamination while enabling rapid on-site analysis, thus resolving the contradiction between analysis speed and measurement precision.
2Productivity
If on-site testing is implemented, then autonomy and speed are improved, but risk of contamination and hygienic shortcomings increase
Solution Approach 1:
The system is segmented into distinct components: a sample collection cup, a sealed cartridge containing the sensor and sample chamber, and an electronic reader. The cartridge acts as a self-contained, sterile unit that is sealed before sample analysis. This segmentation allows the sensitive sensor components to be protected from contamination while enabling autonomous on-site testing, thus resolving the contradiction between autonomous analysis capability and contamination risk.
Solution Approach 2:
The cartridge is designed as a disposable, single-use component that is sealed and discarded after one analysis. This eliminates the need for complex sterilization and cleaning procedures, ensuring hygienic conditions for each test while maintaining autonomous on-site operation. The disposable nature of the cartridge directly addresses the contamination risk while preserving the speed and autonomy benefits.
3Measurement precision
If traditional laboratory analysis is used, then measurement precision is improved, but loss of time and cost increase
Solution Approach 1:
The patent replaces complex laboratory mechanical analysis systems with a simplified electronic sensor-based measurement system. The sensor directly measures parameters such as electrical conductivity, impedance, or capacitance of the sample fluid, eliminating the need for time-consuming laboratory procedures. This substitution maintains measurement precision while dramatically reducing analysis time and cost.
4Ease of operation
If wireless communication components are added to the lid element, then ease of operation and data transmission are improved, but device complexity increases
Solution Approach 1:
The antenna and electronic circuitry are merged with the lid element structure, forming an integrated assembly. The support member on the lid element serves as the mounting structure for both the sensor and the wireless communication components. This merging eliminates the need for separate housings or additional structural elements, thereby improving ease of operation through wireless data transmission while minimizing the increase in device complexity.
