Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a powder material is used for 3D modeling, then productivity is improved through additive manufacturing, but surface smoothness deteriorates leading to rough surfaces
Solution Approach 1:
The patent applies parameter changes by modifying the surface properties of powder particles through coating with organic materials and surfactants. This changes the surface energy and wettability parameters, enabling better surface finish during the 3D modeling process while maintaining manufacturing efficiency.
Solution Approach 2:
The patent uses composite materials by creating coated powder particles consisting of a base material core with an organic material shell and surfactant layer. This composite structure combines the structural integrity of the base material with the surface-active properties of the coating, achieving both productivity and surface quality.
2Manufacturing precision
If layer thickness is reduced to improve dimension accuracy, then manufacturing precision is improved, but layer strength deteriorates leading to collapse
Solution Approach 1:
The patent changes the chemical and physical parameters of the powder surface through organic coating and surfactant addition. This modifies adhesion properties and material strength characteristics, allowing thin layers to maintain sufficient strength while achieving high dimension accuracy.
Solution Approach 2:
The organic material coating and surfactant act as intermediaries between the powder particles and the binding agent. This intermediary layer enhances interlayer adhesion and structural integrity, preventing collapse of thin layers while enabling precise dimensional control.
3Adaptability or versatility
If mixed powder is used to achieve desired properties, then adaptability is improved, but fluidity deteriorates causing uneven distribution
Solution Approach 1:
The patent applies parameter changes by introducing surfactants that modify the surface energy and flow characteristics of the powder mixture. This enables mixed powders with diverse material properties to maintain good fluidity and uniform distribution during the modeling process.
Solution Approach 2:
The patent applies local quality by ensuring uniform coating distribution across all powder particles. This consistent surface treatment throughout the powder batch maintains uniform flow properties and fluidity, enabling adaptable material compositions to be processed evenly.
