Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing three-dimensional modeling apparatuses face challenges in maintaining fabrication quality due to dispersion of modeling materials when colliding with objects, leading to variations in landing positions and degraded accuracy.
Innovation Solution
A three-dimensional modeling apparatus that applies a predetermined external force, such as an electric field, airflow, or gravity, to the modeling material during flight to reduce variations in landing position and improve accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the modeling material is caused to fly to the object without external force application, then the material can reach the object surface, but the material disperses upon collision and landing position varies, degrading fabrication quality
Solution Approach 1:
The patent applies an external force to the modeling material during its flight before it reaches the object surface. This preliminary action counteracts the dispersion tendency and inertia that would otherwise cause inconsistent landing positions and degradation of fabrication quality. By acting on the material while it is still in flight, the system prevents the harmful effects of uncontrolled collision and dispersion.
2Manufacturing precision
If ultraviolet irradiation is applied after the modeling material adheres to the object, then the material is cured, but the material may disperse during collision before curing, degrading fabrication quality
Solution Approach 1:
The patent applies an external force to the modeling material during its flight to prevent dispersion before the material adheres to the object surface. This preliminary counteraction occurs before the harmful dispersion effect can manifest, ensuring that the material maintains its integrity upon collision and adhesion, thereby enabling subsequent ultraviolet curing to proceed without quality degradation.
