Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If paramagnetic beads are used in assays, then high-throughput multiplex analysis is enabled, but external electromagnetic forces cause bead clumping and orientation issues leading to inaccurate results
Solution Approach 1:
A shield structure is introduced as an intermediary element between the external electromagnetic environment and the paramagnetic beads. The shield acts as a mediator that blocks or attenuates external electromagnetic forces, preventing them from directly affecting the beads during analysis, thus maintaining both high-throughput capability and result accuracy
2Ease of operation
If paramagnetic beads are manipulated in solution, then assay procedures can be performed, but external electromagnetic forces interfere with bead behavior causing variability
Solution Approach 1:
The shield serves as a protective intermediary that creates an electromagnetic isolation zone around the assay environment. This allows standard assay procedures to be performed without modification while preventing external electromagnetic forces from causing bead behavior variability, thereby maintaining both operational ease and measurement precision
3Adaptability or versatility
If multiple laboratory devices are used for assays, then comprehensive analysis is possible, but device complexity and mechanical vibrations increase
Solution Approach 1:
The system merges multiple assay functions into a single integrated platform that can perform comprehensive multiplex analysis. The shield encompasses this integrated system, protecting it from external electromagnetic forces while enabling diverse assay capabilities without requiring multiple separate devices, thus reducing overall system complexity and mechanical vibrations
