Multi-Color 3D Pen Nozzle for Simultaneous Extrusion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional 3D pens can only extrude a single color at a time, requiring frequent material changes and preventing the blending of different colors, which significantly reduces operator efficiency and creativity.
Innovation Solution
A 3D pen design that allows simultaneous extrusion of multiple colors using a shell, control mechanism, transmission mechanisms, feeding mechanisms, and a nozzle, enabling users to load all materials at once and switch colors without powering off, with features like microprocessor control, temperature adjustment, and speed control for blending primary colors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a conventional 3D pen extrudes a single color drawing material at a time, then the device structure remains simple, but the operator's working efficiency decreases due to frequent material changes
Solution Approach 1:
The patent divides the single extrusion system into multiple independent extrusion systems, each capable of handling a different color drawing material. The nozzle is segmented into multiple extrusion holes (e.g., three holes for three colors), and multiple drawing material storage chambers are provided. This segmentation allows simultaneous extrusion of multiple colors, eliminating the need for frequent material changes and significantly improving working efficiency while maintaining manageable device complexity through modular design.
Solution Approach 2:
The patent creates a multi-functional nozzle that can simultaneously perform multiple extrusion functions. The nozzle structure includes multiple extrusion holes that can output different colored drawing materials at the same time, making a single device capable of creating multi-color 3D drawings without requiring multiple separate pens or frequent material swaps. This multi-functionality directly addresses the efficiency problem while keeping the device integrated rather than requiring multiple separate units.
2Adaptability or versatility
If a conventional 3D pen uses a single color drawing material, then the device operation is simple, but the ability to blend colors and create mixed colors is lost
Solution Approach 1:
The nozzle is divided into multiple extrusion holes, each corresponding to a different color drawing material. This segmentation allows different colors to be extruded simultaneously or selectively, enabling color blending capabilities. The control system can independently manage each extrusion hole, providing versatility in color combination while maintaining relatively simple operation through automated control.
Solution Approach 2:
The patent merges multiple color streams at the nozzle tip, allowing drawing materials of different colors to be extruded simultaneously and blend together. The multiple extrusion holes are positioned to allow their outputs to mix, creating new colors directly at the extrusion point. This combining approach provides color blending versatility while the automated control system keeps operation straightforward.
3Loss of time
If frequent material changes are required, then single color extrusion is maintained, but time is lost and operator focus is disrupted
Solution Approach 1:
The patent provides multiple drawing material storage chambers that are pre-loaded with different colored drawing materials before operation begins. This preliminary preparation eliminates the need for frequent material changes during the drawing process. The operator can select and switch between pre-loaded colors without stopping to replace materials, significantly reducing time loss and maintaining operator focus throughout the creative process.
Solution Approach 2:
The integrated multi-chamber design allows the device to store and access multiple drawing materials simultaneously, making the device itself multi-functional rather than requiring external material swaps. This universal storage capability reduces time loss by having all needed materials readily available, while the compact integrated design keeps the added complexity manageable within a single device structure.
