Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a burned program is used in the driver chip to control droplet movement, then the driving signal can be provided stably, but the droplet can only move in a single fixed path and cannot meet diverse movement route needs
Solution Approach 1:
The patent transforms the static, fixed droplet path into a dynamic, user-configurable path. By providing an interface that allows real-time editing of droplet movement paths and dynamically generating driving signals based on user input, the system enables the droplet to adapt its movement route according to different experimental needs without requiring program reburning or complex modifications.
2Ease of operation
If the driver chip uses a fixed burned program, then the device structure remains simple, but it requires complex program modifications and repeated burning to change droplet paths
Solution Approach 1:
The system enables users to independently configure and edit droplet movement paths through an intuitive interface without requiring professional programming knowledge or access to the driver chip's internal program. The path planning window allows users to visually define movement routes, and the system automatically generates the corresponding driving signals, making the droplet path configuration serviceable by end users themselves.
3Adaptability or versatility
If multiple path options are provided in the interface, then droplet movement flexibility is improved, but the interface complexity increases
Solution Approach 1:
The patent segments the droplet movement path into discrete, manageable components that can be independently configured and edited. The path planning window divides the movement route into multiple path points or segments, allowing users to modify individual segments without affecting the entire path, thereby reducing the perceived complexity while maintaining high versatility.
