Printing Apparatus Casing with Movable Cover and Printhead Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing printing apparatuses, such as thermal transfer overprinters, are vulnerable to damage from liquids and solids during cleaning processes, leading to malfunction and reduced lifespan, and current protection methods are time-consuming and labor-intensive.
Innovation Solution
A casing with a moveable cover member that provides integrated ingress protection, allowing the printhead to be protected by moving between open and closed positions, and includes a cleaning portion for simultaneous printhead cleaning during production line cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a waterproof bag or hood is manually covered during cleaning, then protection against liquids is achieved, but time consumption and storage space requirements increase
Solution Approach 1:
The cover member is integrated into the printing apparatus housing, merging the protection function with the existing structure. This eliminates the need for separate waterproof bags or hoods, reducing storage space requirements and eliminating manual covering operations during cleaning.
Solution Approach 2:
The cover member is made moveable between open and closed positions, allowing dynamic adjustment during cleaning operations. This enables the cover to be opened for cleaning access and closed for protection, eliminating the need for separate protective covers and reducing time consumption.
2Object-affected harmful factors
If the printing apparatus is removed from the production line during cleaning, then protection against liquids is achieved, but labor intensity and risk of incorrect reinstallation increase
Solution Approach 1:
The moveable cover member allows the printing apparatus to remain installed on the production line while providing liquid protection. The cover can be opened for cleaning access and closed for protection, eliminating the need to remove and reinstall the apparatus and reducing labor intensity.
Solution Approach 2:
The cover member is segmented from the main housing, allowing independent movement and operation. This segmentation enables the cover to be opened for cleaning while the printing apparatus remains in place, reducing the complexity of removal and reinstallation operations.
3Object-affected harmful factors
If dummy parts are exchanged with functional parts during cleaning, then protection against liquids is achieved, but time consumption and risk of incorrect reinstallation increase
Solution Approach 1:
The moveable cover member provides continuous protection without requiring part exchanges. The cover can be opened for cleaning access and closed for protection, eliminating the time-consuming process of removing functional parts and installing dummy parts.
4Ease of operation
If the cover member is made moveable for cleaning access, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The cover member is designed as a flexible component that can be easily moved between open and closed positions. This flexible design provides cleaning access without requiring complex mechanical mechanisms, reducing the increase in device complexity.
