Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If photo-curing printing technology uses a single printing material channel, then the device structure remains simple, but only monochrome printing can be achieved
Solution Approach 1:
The printing head assembly is segmented into multiple independent discharging assemblies (first discharging assembly and second discharging assembly), each responsible for different colors. This segmentation allows each sub-assembly to remain relatively simple while collectively achieving color printing capability, resolving the contradiction between versatility and complexity.
Solution Approach 2:
The bearing member is designed as a universal support structure that can simultaneously hold both the discharging assembly and the optical assembly. This multi-functional design allows a single component to serve multiple purposes, reducing overall device complexity while enabling color printing through coordinated operation of multiple assemblies.
2Adaptability or versatility
If multiple discharging assemblies are integrated on one bearing member, then color printing is enabled, but the device structure becomes more complex
Solution Approach 1:
Multiple discharging assemblies and the optical assembly are merged onto a single bearing member, forming an integrated printing head assembly. This merging approach consolidates multiple functions into one structural unit, enabling color printing while managing complexity through unified design rather than separate independent systems.
Solution Approach 2:
The bearing member is designed with three-dimensional spatial arrangement capabilities, allowing discharging assemblies and optical assemblies to be positioned at different spatial locations and angles. This dimensional arrangement optimizes the layout of multiple components, reducing structural complexity by utilizing spatial efficiency rather than requiring linear or planar arrangements.
