Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a liquid reservoir portion is used for storing reagents in microfluidic devices, then reagent storage capacity is improved, but precise quantitative release control deteriorates
Solution Approach 1:
The device is divided into separate functional modules: a liquid reservoir portion for storage and a body portion with puncturing portion for controlled release. This segmentation allows the storage function to be optimized for capacity while the release mechanism is optimized for precision, resolving the contradiction between storage capacity and release control.
Solution Approach 2:
The puncturing portion acts as an intermediary mechanism between the liquid reservoir and the microfluidic system. It provides a controlled interface that enables precise quantitative release of reagents from the reservoir, transforming the uncontrolled storage capacity into controlled dispensing capability.
2Productivity
If reagent release is made rapid and efficient, then detection speed is improved, but storage stability deteriorates
Solution Approach 1:
The liquid reagent is pre-loaded and sealed in the liquid reservoir portion before use, maintaining storage stability. The puncturing mechanism is prepared in advance but remains inactive until needed, allowing rapid release only when required. This preliminary preparation resolves the contradiction between storage stability and release speed.
Solution Approach 2:
The device transitions from a static sealed storage state to a dynamic release state through the puncturing action. The puncturing portion remains retracted during storage to maintain stability, then advances to puncture and enable rapid release when needed, providing dynamic control that reconciles storage stability with detection speed.
