Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a super absorbent polymer is used to concentrate a sample solution, then the concentration of the sample solution is improved, but the concentration fold ratio cannot be controlled
Solution Approach 1:
The device divides the sample solution into two parts: a first sample solution that is absorbed by the super absorbent polymer, and a second sample solution that is held in the holding chamber. This segmentation allows independent control of absorption amount and held amount, enabling precise control of the concentration fold ratio while achieving high concentration.
Solution Approach 2:
The invention changes the parameters of the super absorbent polymer (particle size, absorption capacity) and the holding chamber (volume, shape) to optimize the concentration process. By adjusting these parameters, the device can control the concentration fold ratio while maintaining high concentration effectiveness.
2Quantity of substance
If water is completely absorbed by the super absorbent polymer, then the concentration fold ratio is improved, but the extraction of concentrated solution becomes difficult
Solution Approach 1:
The holding chamber acts as an intermediary that stores a portion of the sample solution separately from the absorption process. This mediator allows the concentrated solution to be extracted easily through the piston without requiring complete absorption by the super absorbent polymer, thus maintaining ease of operation while achieving high concentration fold ratio.
Solution Approach 2:
The device performs preliminary action by holding a portion of the sample solution in the holding chamber before the absorption process. This preliminary separation ensures that the concentrated solution can be easily extracted later through the piston, avoiding the difficulty of extracting from a completely absorbed state.
3Ease of operation
If a piston with holes is used to extract the concentrated solution, then the ease of extraction is improved, but the particle size control of the super absorbent polymer becomes critical
Solution Approach 1:
The invention specifies precise parameter ranges for the super absorbent polymer particle size (0.1-5.0 mm) to ensure proper function with the piston holes. By controlling this parameter, the device achieves both easy extraction through the piston and maintains the integrity of the absorption process.
Solution Approach 2:
The piston with holes utilizes hydraulic principles to extract the concentrated solution. The hole size (0.01-0.5 mm) is designed to work with the super absorbent polymer particle size, creating a system where fluid dynamics enable easy extraction while maintaining control over the polymer particles.
