Additive Manufacturing Marking Device for Substrate Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in additive manufacturing of buildings or their components lies in accurately positioning the structure or component on a surface, particularly due to environmental conditions and obstacles, which can lead to incorrect placement and collisions with existing reinforcements, requiring time-consuming and error-prone manual measurements or complex marking mechanisms.
Innovation Solution
A device with a material dispensing unit that can move in multiple degrees of freedom, equipped with a marking device operatively connected to the conveyor device, allowing for efficient and accurate marking of the printing path on the surface without material output, using a laser or aerosol marking system that can be activated and deactivated based on the printing path, ensuring precise alignment and avoiding collisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual measurement and marking methods are used to position the printing path, then the positioning accuracy can be improved, but the time consumption and error probability increase significantly
Solution Approach 1:
The patent replaces manual mechanical measurement and marking operations with an automated optical marking system. A marking device with a laser or aerosol marker automatically marks the printing path on the substrate based on digital positioning data, eliminating the need for manual measurement and marking while maintaining high positioning accuracy and significantly reducing time consumption.
Solution Approach 2:
The system enables self-positioning and self-marking capabilities. The marking device is integrated into the 3D printing system and automatically determines the printing path position based on substrate detection, then autonomously marks the path without requiring external manual intervention, making the system self-sufficient in the positioning and marking process.
2Manufacturing precision
If a pen marking device is clamped in the material dispensing unit, then the printing path can be marked visually, but the material dispensing unit may collide with obstacles such as reinforcements
Solution Approach 1:
The patent extracts the marking function from the material dispensing unit by providing a separate, dedicated marking device. This marking device can be independently positioned and controlled, allowing it to mark the printing path from a safe distance without interfering with the material dispensing operation or risking collision with obstacles like reinforcements.
Solution Approach 2:
The marking device acts as an intermediary between the positioning system and the substrate. It receives positioning information from the control system and translates it into visual marks on the substrate, serving as a mediator that enables accurate path visualization without requiring direct contact between the material dispensing unit and the substrate surface.
3Manufacturing precision
If the pen marking device is used to mark the substrate, then the printing path can be visualized, but complex control systems and fastening mechanisms are required to manage vertical movement and marking activation
Solution Approach 1:
The marking device is designed as a multi-functional component that integrates positioning, marking, and activation control into a single unit. It can be positioned vertically to match the substrate surface and automatically activated based on the printing path requirements, eliminating the need for separate complex control systems and fastening mechanisms while maintaining marking accuracy.
