Solution Overview
Problem
Existing analysis devices face challenges in reliably fitting together the chip and cartridge components, which are crucial for accurate component analysis in samples, often resulting in positional misalignment and inefficient sample measurement.
Innovation Solution
The analysis device incorporates a placement section, a pressing member, and a measurement member to securely fit the chip and cartridge together, using positioning pins and a pressing mechanism to ensure precise alignment and sealing, allowing for reliable measurement of sample components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the chip and cartridge are designed to be assembled manually without additional fitting mechanisms, then the device structure remains simple, but positional misalignment occurs between the chip and cartridge
Solution Approach 1:
The patent introduces a cartridge as an intermediary component that mediates between the chip and the analysis device. The cartridge contains positioning protrusions that engage with corresponding recesses in the chip, ensuring accurate positioning during assembly. This intermediary structure enables reliable fitting without requiring complex direct coupling mechanisms between the chip and device housing.
2Manufacturing precision
If positioning protrusions and recesses are added to ensure precise fitting, then positioning accuracy improves, but the device structure becomes more complex
Solution Approach 1:
The patent divides the assembly into three distinct segments: the chip, the cartridge, and the analysis device housing. The positioning protrusions and recesses are distributed across these segments rather than concentrated in one complex interface. Specifically, the cartridge has positioning protrusions that fit into recesses in the chip, while the cartridge housing fits into recesses in the device housing, creating multiple simple positioning interfaces instead of one complex interface.
3Manufacturing precision
If the chip and cartridge are fitted tightly to prevent misalignment, then positioning accuracy improves, but sample introduction becomes difficult
Solution Approach 1:
The patent applies different fitting tightness to different regions of the chip-cartridge assembly. The main body of the chip is tightly fitted to the cartridge through positioning protrusions and recesses to ensure positioning accuracy. However, the sample introduction region maintains a looser fit with gaps that allow easy insertion of samples. This localized differentiation of fitting quality enables both precise positioning and easy sample introduction.
