Movable Print Head Support for Digital Decorator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Digital decorator machines for ceramic tiles and similar materials face issues with non-functioning print heads being exposed to degrading agents, leading to malfunctions and increased maintenance needs due to their proximity to the decorated surface during four-color process operations.
Innovation Solution
The machine features movable print head supports that can be positioned above the surface when not in use, along with a protective casing and removable protection to shield the heads from degrading agents, and allows for easy exchange and maintenance of print elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If non-functioning print heads are kept close to the product surface for quick access, then operational readiness is improved, but the heads are exposed to degrading agents causing malfunctions
Solution Approach 1:
The support structure enables the print heads to dynamically change position between an upper inactive position (protected from degrading agents) and a lower operating position (close to product surface for dispensing). This dynamic positioning resolves the contradiction by allowing the system to optimize for protection during non-operation and for accessibility during operation.
2Adaptability or versatility
If multiple print elements are arranged side-by-side for versatile decoration, then adaptability is improved, but the complexity of protecting non-functioning heads increases
Solution Approach 1:
The decoration machine is divided into multiple independent print elements, each with its own support structure capable of independent movement between active and inactive positions. This segmentation allows each print head to be individually protected or deployed based on operational needs, providing versatility while managing complexity through modular design.
Solution Approach 2:
The support structure serves multiple functions: it holds the print head in an operational position during decoration work, moves the print head to a protected position when inactive, and provides a removable protection barrier. This multi-functionality reduces the need for separate protection mechanisms for each print element, simplifying the overall system.
3Manufacturing precision
If print heads remain stationary close to the surface, then positioning precision is maintained, but exposure to degrading agents increases
Solution Approach 1:
The system dynamically adjusts the position of print heads based on operational state. During active decoration, heads are positioned precisely close to the product surface. During inactive periods, heads are moved to an upper protected position, eliminating exposure to degrading agents while maintaining positioning precision when needed.
