Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If ink containing inorganic pigment is used for printing, then cosmetic makeup quality is improved, but pigment precipitation occurs and ejection properties deteriorate
Solution Approach 1:
The ink circulation device circulates ink before it reaches the inkjet head to prevent pigment precipitation in advance. The circulation path includes a reservoir and pump system that continuously moves the ink, keeping pigments suspended and preventing them from settling before ejection.
Solution Approach 2:
The ink circulation device operates continuously to maintain ink flow and pigment suspension. The pump continuously circulates ink through the circulation path, ensuring that the ink remains in a stable, non-precipitated state throughout the printing process.
2Manufacturing precision
If inkjet printing is used for cosmetic application, then printing precision is improved, but ink mist generation increases
Solution Approach 1:
The body deelectrification device converts the harmful effect of static electricity (which causes ink mist) into a benefit by neutralizing the static charge. The capacitor discharges accumulated static electricity, preventing mist generation while maintaining the precision of inkjet printing.
Solution Approach 2:
The body deelectrification device changes the electrical parameter of the system by discharging static electricity. This parameter change (removing static charge) prevents the electrostatic forces that would otherwise cause ink to atomize into mist during ejection.
3Object-generated harmful factors
If static electricity accumulates in the printer body, then ink mist increases, but deelectrification is needed
Solution Approach 1:
The body deelectrification device uses a capacitor that can be periodically discharged to remove static electricity. This is a simple, low-cost solution compared to complex continuous deelectrification systems, providing effective mist reduction through periodic energy discharge.
Solution Approach 2:
The body deelectrification device replaces complex mechanical deelectrification mechanisms with an electrical solution using a capacitor. This substitution simplifies the overall device complexity while effectively managing static electricity and reducing ink mist generation.
4Reliability
If ink circulation device is added to prevent pigment precipitation, then ejection properties are improved, but device complexity increases
Solution Approach 1:
The ink circulation device serves multiple functions: it prevents pigment precipitation, maintains ink flow, and can be integrated with the existing inkjet system. This multi-functionality justifies the added complexity by providing several benefits from a single integrated system.
Solution Approach 2:
The ink circulation device is merged with the inkjet printer system, combining the circulation function with the existing ink delivery mechanism. This integration reduces overall system complexity compared to having separate circulation and printing systems operating independently.
