Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If independent driving structures are used for moving components in a kit, then the components can be moved independently, but the structure becomes complicated and the cost increases
Solution Approach 1:
The patent combines multiple independent driving structures into a single integrated piston system. The piston can move linearly to transfer liquids between chambers and rotate to align different sub-chambers with the detection chamber, eliminating the need for separate driving mechanisms for each component and simplifying the overall structure.
Solution Approach 2:
The piston is designed as a multi-functional component that performs both linear movement for liquid transfer and rotational movement for chamber alignment. This universal component replaces multiple specialized driving structures, reducing system complexity while maintaining independent control over different operational functions.
2Ease of operation
If independent driving structures are used for moving components in a kit, then the components can be moved independently, but the cost increases
Solution Approach 1:
By merging multiple independent driving structures into a single piston assembly, the patent reduces the number of parts that need to be manufactured and assembled. This integration lowers manufacturing costs while preserving the ability to independently control liquid transfer and chamber alignment operations.
3Productivity
If multiple sub-chambers are used for different reagents, then reagent handling efficiency improves, but the device structure becomes more complex
Solution Approach 1:
The patent merges multiple sub-chambers containing different reagents into a single rotatable plate assembly. The piston can rotate this plate to bring different sub-chambers into alignment with the detection chamber sequentially, enabling efficient reagent handling through a single integrated structure rather than multiple separate chamber systems.
Solution Approach 2:
The rotatable plate with multiple sub-chambers introduces dynamic reconfiguration capability. Instead of fixed complex piping and valve systems, the system uses simple rotational movement to dynamically connect different reagent chambers to the detection chamber, simplifying the overall structural complexity while maintaining high productivity.
