Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional electric field generation methods are used, then the system is simple, but the ability to manipulate and measure charged species accurately is limited
Solution Approach 1:
The electrode system is segmented into multiple electrode elements (first electrode element, second electrode element, third electrode element) that can be independently controlled. Each electrode element can generate electric fields in specific regions, allowing precise manipulation of charged species at different locations within the sample region.
Solution Approach 2:
Different regions of the sample are subjected to different electric field conditions. The first region receives an electric field from the first and second electrode elements, while the second region receives a different electric field from the second and third electrode elements. This local differentiation enables selective manipulation and measurement of charged species in different areas.
2Adaptability or versatility
If uniform electric field is applied, then the system is simple to control, but the interaction with target analytes is insufficient
Solution Approach 1:
The electric field configuration is made dynamic by enabling independent control of multiple electrode elements. The controller can adjust the voltage applied to each electrode element separately, allowing the system to adapt to different measurement requirements and manipulate charged species with varying charges and masses.
Solution Approach 2:
The system changes electric field parameters (strength, direction, distribution) by independently controlling the voltage applied to each electrode element. This allows optimization of electric field conditions for different types of charged species and different measurement objectives.
