Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 3D dispensing technologies face challenges in processing multiple sides or faces of a 3D substrate efficiently, requiring multiple axes of motion for the print head but often resulting in complex and costly systems with increased hardware and space requirements.
Innovation Solution
A 3D dispensing apparatus and method utilizing at least two dispense heads with a motion control module enabling three orthogonal linear motions and two divergent rotational motions, allowing simultaneous operation in a compact system with reduced hardware and computer controls, and simplified tool-path generation, where the dispense heads and fixtures are arranged to realize rotational movements through a slave unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple axes of motion are added to process multiple sides of 3D substrate, then processing capability is improved, but system complexity and hardware requirements increase
Solution Approach 1:
The patent combines multiple dispense heads into a single integrated system that shares common motion control mechanisms. Multiple heads are mounted on a moving platform that executes coordinated 5-axis motion, allowing simultaneous processing of multiple articles or multiple sides of articles without requiring separate motion systems for each head.
Solution Approach 2:
The motion platform and control system serve multiple functions by enabling both positional movement and rotational orientation of the dispense heads. The system can process multiple sides of 3D substrates, handle multiple articles simultaneously, and adapt to different processing requirements through programmable motion sequences.
2Productivity
If multiple dispense heads operate simultaneously, then productivity increases, but hardware requirements and space needs increase
Solution Approach 1:
Multiple dispense heads are arranged in a compact configuration where they share common support structures and motion mechanisms. The heads are positioned to operate in coordinated fashion over a shared workspace, maximizing the use of available space and minimizing the overall footprint of the system.
Solution Approach 2:
The system utilizes 5-axis motion including two rotational axes to enable dispense heads to access multiple sides and angles of 3D substrates. This dimensional capability allows simultaneous processing of multiple articles in a compact arrangement without requiring additional linear space.
3Adaptability or versatility
If 5-axis motion is implemented, then processing versatility improves, but control complexity increases
Solution Approach 1:
The system employs automated motion control with programmable sequences that manage the complexity of 5-axis coordination. The control software handles the intricate calculations and synchronization of multiple axes automatically, reducing the need for manual intervention and simplifying operation despite the underlying complexity.

AI summary
A 3D dispensing apparatus and method. The apparatus includes a motion platform, at least two dispense heads for dispensing and multiple fixtures for holding articles to be processed simultaneously, a motion control module for automated motions of said dispense heads relative to said fixtures. Said motions includes three orthogonally X-Y-Z arranged linear motions and first and second rotational motions, the rotational axis of the first rotational motion being divergent from the rotational axis of the second rotational motion. The dispense heads or the fixtures are arranged to a slave unit being arranged to realize at least one of said two rotational movements so that the dispense heads or the fixtures therein realize simultaneously and equally said rotational motion.
