Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual operation or basic suction mechanism is used for dispensing, then device complexity is low, but productivity and working efficiency are poor
Solution Approach 1:
The device is divided into functionally independent modules: a head device for suction and discharge operations, a separate automation mechanism with piston member and shaft members, and a control system. This segmentation allows each module to be optimized independently while maintaining overall system efficiency.
Solution Approach 2:
The dispensing tip is designed to be automatically mounted and detached by the head device itself through coordinated movement of the tubular rod and guide portion, eliminating the need for external manual intervention in the mounting process.
2Productivity
If automation mechanism is added to dispensing tip, then productivity improves, but device complexity increases
Solution Approach 1:
The automation mechanism is integrated into the head device structure, where the piston member, shaft members, and tubular rod work together as a unified system. This merging reduces the need for separate external automation components and simplifies the overall system architecture.
Solution Approach 2:
The head device serves multiple functions: it holds the dispensing tip, provides automated suction through piston movement, enables discharge through controlled movement, and facilitates automatic mounting/detachment of the dispensing tip. This multi-functionality reduces the need for additional specialized components.
3Extent of automation
If dispensing tip is manually operated, then ease of operation is high, but extent of automation is low
Solution Approach 1:
The control system receives feedback from the shaft members' positions and the piston member's movement state to automatically adjust operations. This feedback mechanism enables the system to perform complex automated sequences while maintaining operational simplicity through centralized control.
Solution Approach 2:
The shaft members act as intermediaries between the control system and the piston member, translating control signals into precise mechanical movements for automated dispensing tip operation, thereby simplifying the user interface while enabling complex automation.
4Productivity
If automated mounting and detachment is implemented, then productivity improves, but device complexity increases
Solution Approach 1:
Instead of actively gripping or clamping the dispensing tip for mounting, the system uses a passive approach where the tubular rod and guide portion create a constrained path that guides the dispensing tip into place through their own movement, inverting the traditional active mounting mechanism.
Solution Approach 2:
The head device automatically performs the mounting and detachment of the dispensing tip through its own structural movement, without requiring external mounting mechanisms or manual intervention, making the system self-sufficient for tip replacement operations.
