Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the flow channel is designed as a closed structure, then fluid delivery reliability is improved, but cleaning difficulty increases and maintenance cost rises
Solution Approach 1:
The flow channel assembly is divided into separable components including the fluid seat, nozzle mounting plate, and nozzle platen that can be disassembled from each other. This segmentation allows the closed structure to maintain reliability during operation while enabling easy access for cleaning and maintenance by separating the components.
2Stability of the object's composition
If the nozzle is fixed securely in the flow channel, then fluid delivery stability is improved, but assembly complexity increases
Solution Approach 1:
Positioning cylinders and positioning grooves are pre-formed on the nozzle mounting plate and nozzle platen respectively. These preliminary positioning features guide the nozzle into correct alignment during assembly, ensuring stable positioning without requiring complex adjustment procedures or multiple assembly steps.
Solution Approach 2:
The positioning cylinders and grooves create a self-aligning assembly system where the nozzle automatically finds its correct position when the components are brought together. This self-service positioning mechanism eliminates the need for complex external alignment tools or procedures.
3Reliability
If multiple components are used to secure the nozzle, then nozzle fixation reliability is improved, but disassembly time increases
Solution Approach 1:
The fixation system is segmented into modular components where the nozzle mounting plate and nozzle platen can be independently removed. This allows the nozzle to be accessed and serviced without requiring the disassembly of the entire fluid seat structure, significantly reducing disassembly time while maintaining reliable fixation during operation.
